I think this bug can be considered fixed now that the raop2 patches have landed
in the "next" branch. The code will be released in PulseAudio 11.0.

Maybe you could try "Configuration file for local devices" in the instruction.

Alex,
Thanks, actually it was fixed in the mainstream:
https://github.com/pulseaudio/pulseaudio/commit/ff06e24eb5e4c00c2b80172dbce0971376fc167f
So I believe this should be in the tree now (as Colin Leroy rebased in against
master recently).

Hakan,
Thank you for trying and reporting.

Successfully compiled and used Fujita-san's Pulseaudio-raop2 fork on Trusty
(Ubuntu 14.04), but I had to apply the patch in the attached URL to make it
compile...

Anyhow, now works like a charm on my Bowers & Wilkins Zeppelin air, so if
Fujita-san wants, it can be added to the list of supported devices...

Thanks for the great work!

I tried Hajime's raop2-for-merge2 branch on my Linux Mint 16 today.
I observed the same effect (no local sound devices). Both local sound and the
connection to my AppleTV 3 failed with "invalid sample format specification" in
the logs, which made me curious.

I tracked the problem: the bug seems to be in PA's handling of configuration
data. If no explicit value is provided, PA should use the default value.
Instead, garbage on stack was returned. The following patch fixes the default
initialization, and both local sound and AppleTV are working fine now.

This is indeed a great work. It works like a charm with my local XBMC. However,
the branch from Hajime Fujita doesn't support IPv6. It should at least ignore
it, but I think it's better to implement it the right way. See
https://github.com/hfujita/pulseaudio-raop2/issues/1 for some details.

Thank you very much to Fujita-san, Matthias et al for all your efforts on this.
I have been hoping for this for quite a while (e.g.

and am very grateful you have tackled this.  It seems to be working very nicely

paprefs requires module-gconf to be loaded in pulseaudio. Did you compile
pulseaudio with gconf support?

Greetings, I have checked out the code from the git repo posted with latest
patches (thanks guys!) and was able to compile it on my Fedora box after
figuring out which libraries I needed in their Fedora equivalent. 

The one thing I noticed while compiling was that I had to disable the
"--enable-x11" flag, I'm not sure if I'm missing another library or if Fedora
just does things in such a different way that I need to use a more extensive
config flag.

It did compile without issues other than that. However, the next step when I
launch paprefs to enable the Apple airplay stuff, and the checkboxes are greyed
out. I am not sure how to proceed. I tried doing an strace to perhaps get some
sort of logical hint I might follow. But have nothing.

Ideas? I can screenshot what I'm seeing but its pretty straight forward.

Hi Matthias,

Okay, actually it took more than I had originally expected, but I finally fixed
a bunch of bugs (some made by you, others by me) and integrated the packet
retransmission feature. It works quite well in my environment, but needless to
say it should be tested in many environments!

That's right - though I think the receiver should not simply ignore the payload
type. But that's not for me to decide.

I think that adds me to the mass of people who don't get C pointer semantics
right :). Thank you for clarification.

Makes sense to me - maybe in my real-world capture case I just overheard the
glitch... it was late last night.

Feel free to do so.

Hi Matthias,

Come to think of it, when I first try your original patch, I didn't see
retransmission request burst, that means it also worked for my device. Sorry
for having jumped into the wrong conclusion.

> A possible explanation could be that my remote device accepts re-sent audio 
> packets at the streaming port > (regardless of payload type(!)) if the 
> sequence number matches the one requested.

This would make sense. In principle there is no order guarantee for UDP/IP, so
the device should expect reordered/delayed packet.
So if the device ignores the payload type field, the behavior would be the same
as for natural reordered packet.


BTW, by reading raop_packet_buffer.c, I realized that pb_get_packet() did not
work (i.e. did not copy the data to the given user buffer).
> packet_data = packet->packet;
This is just manipulating the pointer, not touching the data referenced by the
pointer.

FYI, in C, it should have been either:
for (i = 0; i < len; i++)
packet_data[i] = packet->packet[i];
or
memcpy(packet_data, packet->packet, len);

As a result, even the retransmission packet was accepted by the device, we
could not expect to hear a meaningful sound from it.
Probably this is the reason that I experienced sound glitch on retransmission
when I tried your patch first.

If you don't mind, I'll take a look and rewrite the code. (At the same time
I'll adapt the code to the latest raop2-for-merge branch.)


Thanks,
Hajime

Hi Hajime,

sorry for keeping you up late with that patch. I would not have sent it if it
had not worked for me. Thank you for testing and (hopefully) fixing it!

>retransmission happens.

I had a similar approach to yours regarding packet retransmission testing (i.
e. intentionally skipping packets in send_audio_packet()). When running this
version with retransmission disabled, result were exactly as you describe - the
remote device kept sending retransmit request. With retransmission enabled, the
device sent exactly one retransmit request (assuming that means the remote
device accepted the re-sent packet).
A possible explanation could be that my remote device accepts re-sent audio
packets at the streaming port (regardless of payload type(!)) if the sequence
number matches the one requested.

Should have looked up [1] and [2] before sending this patch :/.

I will test retransmission with Airtunes and my Minx Air. Maybe we can get some
information about the retransmission scheme from that.

Maybe a better way would be to add a flag parameter for retransmission and
another parameter for the sequence number (with c->seq as default).

I'm pretty sure there are better ways to do what I did :). As mentioned, my
experience in C (or anything without automatic memory management) boils down to
two weeks of patching.
Any feedback is welcome.

Will try your version with my device tonight and report back.

Greetings,

Matthias

A patch to Matthias's packet retransmission patch (85150)

This patch provides several fixes to Matthias's patch, so that it works for
Pioneer VSX-43.
This is an experimental patch with several dirty hacks, thus should not be

Hi Matthias,

Thank you for taking a crack on the packet retransmission feature.
I was so excited that I almost forgot to have a dinner. :)

I tried your patch (on v4.0+raop at this moment), but unfortunately it did not
work, in a sense that I still hear some sound jump when a packet retransmission
happens.

After a quick research, I found several issues:
1. "payload type" of the retransmission packet should be 86 (0x56) [1]
2. retransmission packets should be sent to the control port [1], not to the
streaming port
3. based on observation of a packet sequence from iPad to VSX-43, the
retransmission packet seems to have a special structure. shairport's
implementation for retransmission handling [2] supports this observation. 

struct retrans_pkt_hdr {
uint16_t rtphdr; /* = htons(0x80d6), where 0xd6 = 0x56(payload type) +
0x80(marker == on) */
uint8_t a; /* unknown; seems always 0x01 */
uint8_t b; /* unknown; seems some random number around 0x20~0x40  */
uint16_t orig_rtphdr; /* maybe; seems always htons(0x8060) */
uint16_t retrans_seq_num; /* in network byte order */
uint32_t retrans_ts; /* RTP timestamp in the original packet */
};

I almost figured out the structure, but I couldn't figure out meanings in 'a'
and 'b' members above.

I wrote a patch for Matthias's patch (attachment #85150) to try the above idea.
I also included a simple packet loss injection scheme to test the feature
efficiently. It intentionally skips 2 consecutive frames (~= 16ms data) per
each second.
(Of course, this dirty hack should be removed in the final version.)

This works for VSX-43. It is difficult to tell if it works by listening to the
music, but I confirmed by the following method.
1. if I disable the retransmission under packet loss injection, the device asks
for retransmission of the same packet (seq. no.) again and again, and I see a
burst of log output.
2. if I enable the retransmission, retransmission request per packet appears
only once. This proves that the device accepts the retransmission packet.
See send_audio_packet() in raop_client.c to try this.

I'm not sure if this works for other devices, as I'm not 100% sure about the
retransmission packet format.

[1]: http://nto.github.io/AirPlay.html#audio-rtpstreams
[2]: https://github.com/abrasive/shairport/blob/master/hairtunes.c#L476

Besides the functionality issues above, I have a few questions regarding
design.
1. in send_audio_packet(), it seems dangerous to use (retrans_seq_num > 0) as a
flag, as the sequence number may wrap (1 in 65536).
2. I'm not sure if we really need to malloc buffer at resend_packets(). Can't
we just use the buffer stored in the pb? Since malloc may fail, I'd rather
avoid calling malloc whenever possible.

Hi Hajime, hi all,

(Bear with me, this is still my first time coding C). 
I implemented a packet retransmission buffer (see attached patch).
It's a simple circular buffer. Each sent audio packet is stored in the buffer,
discarding the oldest packet. Buffer size is set to 1000 packets, according to
[1].

At a retransmission request from the remote device, the requested packet is
retrieved from the buffer and re-send with a retransmission header.

Hajime: The attached patch is against your v4.0+raop branch. I tried to keep
the patch to raop_client.c small - it would be great if you could merge it into
your raop2-for-merge branch. I could help out if you are short on time.

I also attached a snippet of a packet dump with my Minx Air. Packets 7 and 8
and 17 and 18, respectively, show a successful retransmission request and
reply.

All: Please test it and report back if you find any flaws.

Btw.: Hajime, you can add another device to your supported device list: Pioneer
VSX-922.

While testing the packet buffer I noticed that the volume level set via PA (I
use the gnome applet shipped with ubuntu 12.04) is not linear. Looking at the
code and comparing it to [2], I think that the volume calculation is wrong. In
the code, volume is calculated between VOLUME_MIN (-144) and VOLUME_MAX (0). I
think it should be calculated between (-30.0) and (0.0), as seen in [2].
Fixing this should be easy.

Greetings,

Matthias

Hi Karl,

> PULSE_SERVER=192.168.0.4:4713 firefox &

I've tested that workaround but didn't get a good result either.

It seems that Flash does not understand the correct sampling rate. This guess
is based on the following facts:
* When I play sound from Flash, apparently its tempo gets slower than the
original.
* By looking at the packet dump, there are sometimes sequences of packets whose
audio payload is all zero (0x00). Probably this "silence" frames cause sound
jumps and result in sound glitch.
* When I look at the net, many people are complaining about the sample rate
issue in Flash

For example, I found several discussions in Chrome+Flash.
* http://code.google.com/p/chromium/issues/detail?id=229918
* https://code.google.com/p/chromium/issues/detail?id=32757#c64
However, the workaround there (setting default-sample-rate to 48000) did not
work.

Hi,

I have reformatted all the patches and uploaded to this `raop2-for-merge`
branch.
https://github.com/hfujita/pulseaudio-raop2/commits/raop2-for-merge

Now it is supposed to support both TCP/UDP protocols.
Because I don't have any TCP devices (e.g. old Airport Express?), I would be
very happy if someone could test it on TCP devices.

I'll later update the instruction to use it.

This might not be relevant, but playing music from flash was a particular
problem also with the original pulseaudio over network protocol.

However there was a workoround:

http://askubuntu.com/questions/122148/flash-in-browsers-does-not-play-sound-accurately-using-pulse-network-audio

In the first answer here the culprit is pointed out to be: "that Flash is
somehow sending the sound to PulseAudio in such a way that it creates a lot of
network traffic (think lots of tiny packets, not bandwidth); this overwhelms
the network "tunnel" PulseAudio has created"

the workaround was the to "cut out the middle man" by disabling discovering of
airtune devices and just starting the web browser like this:

PULSE_SERVER=192.168.0.4:4713 firefox &

I havent been able to test this with Hajime's RAOP module though.

Taking a quick look at wireshark I can se that a lots of tiny packets is not
the problem at least not here. And the bandwith is about the same ca 180kbit/s
with flash as with working aplications. 

The only diference I can se is that the Flash aplication is sending music
packets over the network even when it is paused.

Hope this information can be useful in someway.

I had a quick look through the developer documentation but did not find
anything. However, if you look at module-raop-sink.c, function
sink_process_msg, it looks to me as if the connect sequence is called when a
PA_SINK_RUNNING state is set. Perhaps we could do the connect (and only this)
when PA_SINK_INIT state is set.
Setting PA_SINK_RUNNING (in my understanding) is set when the sink is connected
and should play audio - this is were audio playback (i.e. sending sync and
audio packets) should happen.

Btw.: I just tested your latest patch (with the memchunk offset) and kindly ask
you to put "Cambridge Audio Minx Air 200" on your supported device list. Works
like a charm :).

Matthias

I meant for example,

1. launch a movie player and start playing any movie
2. the picture starts moving almost immediately but the sound track have to
wait until the Airplay device is initialized (usually takes a few seconds)
3. Therefore there will be a huge gap between the picture and the sound track.

I'm not sure how the circular buffer would resolve this issue. (Buffer in
general sounds like increasing the delay.)
I think the fundamental issue is that a client (movie/music player) thinks that
the audio device (PulseAudio) is ready and starts playing the picture, while
atcually it is not ready yet.

I guess there should be some way to tell the application that "we are not ready
yet", or at least tell some latency. I think we need to understand more about
PulseAudio internals.

Of course not :) Anyone is welcome to fork from my tree.

However, please note that I'm now completely reformatting all patches
(including Martin's) so that
* they could support both TCP and UDP protocols at the same time
* they could easily be merged into master

So in near future my current "v4.0+raop" branch will be revoked and I'll move
to the new, clean branch.
However even in that case, I think I can take care of moving your additinal
patches to the new branch if these patches are relatively small.

Hi Hajime,

I'm not a law expert either. To be honest, I hate to dig through compatibility
descriptions of "free" software licenses instead of happily hacking a packet
buffer while listening to music over Airtunes 2 (tm) by Apple (tm) (I'll add an
extra (tm) here and there just to be sure ;)).

Just to clarify: I would be happy to release libSALAC under LGPLv3. PA would
only link to libSALAC. Library use of a LGPL library should be ok for GPL code.
libSALAC, in turn, could "library use" Apache V2.0 ALAC. But that's just my
understanding - I'm not a software lawyer (and I don't want to be one).

You mentioned a "huge latency" in your project description on github [1]. If by
"huge latency" you mean the interval of time between "playing a sound" and the
_first time_ your airplay device plays that sound, I could think of a way to
circumvent this:

1. Implement a circular packet buffer (I am about to do this).
2. Start filling the circular buffer when module_raop_sink is loaded (i. e. in
module-raop-sink.c function thread_func, whether the sink is in a "running"
state or not).
3. Send packets from the packet buffer using pa_raop_client_send_audio_packet
(as in the current implementation).
4. As a side effect, one could easily implement packet resending by using the
sequence information of the packets in the circular buffer (which in the end is
just an array).

I also noticed this delay - looking at the packet dump of a sound clip played
via airtunes it seems as if:

1. pa_sink_render_full (in module-raop-sink.c) is subsequently called after the
sink is in running state, but
2. the playback starts *after the first three timing packets are exchanged*
(after RTSP RECORD).

As a result, there is a gap (in matter of time) between the moment when
pulseaudio moves the sink from your previously selected device to the airplay
device and the point in time where the timing packet exchange is done.

If you listen to several sound clips (read: songs of a playlist) subsequently,
the interval between the player announcing a new song and start of playback is
minimal.

However, there will always be a delay between sound data relayed to PA and
playback on the remote device.

Hajime, would you mind if I forked your project github to test my packet
buffer?

Good night,

Matthias

Hi Matthias,

Thank you so much for the testing and reporting.

By looking at your patch for ALAC support, I found out that the real issue
might not be in the ALAC encoding, but in the raw buffer handling.
I wrote a one-line patch inspired by your patch.
https://github.com/hfujita/pulseaudio-raop2/commit/3b35e02e473873f64e2a5967f4cc55e05ae9d00a
This fixes the "rough sound" issue in my VSX-43+Ryhthmbox, even without Apple's
codec integration.
I'm happy to hear any results from testing this patch.
(However, the sound from Adobe Flash is still terrible. I suppose this is due
to a different cause.)

Regarding ALAC licensing, I actually had a similar concern. That's why I
haven't made my ALAC integration branch public, while I already have it
locally.

Since I'm not a law expert in any sense, the following should not be taken
seriously :)
In the most optimistic way of thinking, header section in each ALAC source file
states that the file is licensed under the Apache License, so I hope we can
just believe it.
However, still I'm not sure if it's okay to link Apache Licensed library into
PulseAudio. The license file in the pulseaudio top directory says that the
server side implementation of PA should be treated as GPL-licensed. So the
question would be "can we link Apache Licensed library to GPL product"?

One possible workaround would be to find another encoder implementation, such
as in libav.

Hi Hajime,

I'm back from my vacation - the first thing I did when I entered my home was to
boot up my laptop and compile your version of pulseaudio :).

First of all, congratulations and thanks for the great job. Second: I also
encountered your "rough sound" issue when playing music with 'banshee'. Reading
your entry here I wondered what that expression meant, but I can't think of a
better description. Sounds like my Minx Air turned into a 20$ bluetooth speark
;).

I used to test my patches with 'banshee' (as it's preinstalled with ubuntu
12.04) and 'gst123'. I also used 'banshee' to test your version of the raop
module - which resulted in the "rough sound" described above.

Today I merged my work on ALAC encoding into your branch. The sound distortion
(using banshee) is gone now. I confirmed that using my Minx Air using RSA
encryption and without encryption (by commenting out encryption in
raop_client.c).

That leaves me at a point where I don't want to be: This is not a programming,
but a license issue. As pointed out in the ALAC trac [1], the license of the
ALAC codec part is ambiguous (Apple Licence vs. Apache V2.0).

Though, as I already wrote: Timothy Gu created a debian package of Apple's (tm)
ALAC library [2]. I used his library to create a simple encoder library [3].
My patch - as the time of writing it's incomplete and more a proof of concept -
uses these libraries (read: libsalac which in turn uses libalac).

I'm not sure if this "library use" could affect the license of any software
that uses libsalac or libalac. Any software license laywers here ;)?

So, back to the technical discussion: It sounds to me (pun intended) as if the
"rough sound issue" can be resolved using "true" ALAC encoding - and in turn,
that present "encoding" does not work correctly in some situations. I've got no
idea why this should affect rhythmbox, gst123 and banshee but not vlc (wild
guess: are rhythmbox, gst123 and banshee built with gstreamer support?).

I did a packet dump of some playback with your branch and libsalac. It shows
series of retransmit requests. I am currently working on a packet retransmit
buffer implementation.

Until then, please find attached a patch for libsalac to Hajime's branch.
Works for me with my Minx Air. As the license issue is still unresolved, this
is just a proof-of-concept patch and should not be included in any software
distribution whatsoever as I do not want to be hunted by Apple's (tm) laywers.

[pulseaudio-tickets] [Bug 42804] raop module does not work with shairport

--- Comment #26 from Hajime Fujita  ---
Thanks Matthius,
Unfortunately it seems that your patch is for some irrelevant files. Looking
forward to hearing from you again after you come back from vacation.

Here are several outcomes of my research these days.

First, I noticed that there were several encryption methods defined in the
protocol[1]. Martin's code only supports RSA and always does encryption. This
may work for Apple devices, but my VSX-43 for example only supports et=0 (no
encryption) and et=4 (MFiSAP). This was the reason that I could not hear any
sound from my device.

I wrote a patch for automatically switching RSA encryption, depending on
device's capability announce. (before that I upgraded the code base to v4.0)
https://github.com/hfujita/pulseaudio-raop2

I also embed ALAC encoder to raop module (which I haven't made public yet --
since I'm not 100% sure about license conditions). Actually, VSX-43 played
sounds either with or without ALAC encoding.

[1] http://nto.github.io/AirPlay.html#servicediscovery-airtunesservice

So Matthuis, your Minx Air 200 required ALAC compression, (i.e. it did not
accept uncompressed PCM+ALAC header) right?

I'm now having an issue that the sound skips every second, propably the same
issue as you have. I'm now trying to understand how the time is managed inside
PulseAudio and figure out how to fix it.

Hi all,

I'm in a hurry as I'm leaving for the holidays tonight.

Just wanted to share my work of the last weeks. I tried to set up a git fork of
http://repo.or.cz/w/pulseaudio-raopUDP.git/shortlog/refs/heads/raop at
http://repo.or.cz/w/pulseaudio-raopUDP/pulseaudio-raop-alac.git but could not
commit my changes. Don't ask why - it's also my first time working with git.

Will try again after my vacation.

Until then, this is the state of play:

1. I wrote a simple wrapper library for Apple's C++ ALAC library. You can fetch
it from http://repo.or.cz/w/libsalac.git. 
It needs libalac from https://github.com/TimothyGu/alac.
After the usual

%autoreconf -i -a && ./configure && make && make install

copy "libsalac.h" from "/usr/local/include/libsalac-1.0/src" to
/usr/local/include/libsalac-1.0".

2. I modified my copy of pulseaudio (see the attached patch) to use libsalac
(configure.ac and Makefile.am).

3. I used libsalac to use Apple's ALAC Encoder to encode audio packets with
ALAC. Careful: I set the initial volume to "-21" in the source. This is
obviously a workaround as the initial volume was not set correctly and audio
was played near mute.

4. As a result, I am now able to play music via pulseaudio to my Minx Air 200.
There are glitches every second (I suspect the sync packets are not quite
right).

Please give it a try.

I also started to implement a packet buffer for resending. I will commit that
when it reaches a stable state.

Hi Matthias,

I'm afraid that this could be out of the topic from this issue, but I have
Pioneer VSX-43 and it does not play music with my latest patch (in comment
#21). If I try to stream music from PulseAudio, the reciver turns into the
AirPlay streaming mode, so the setup phase seems to be woking. I also tried to
use node-airtunes before but for some reason it did not work (node-airtunes
itself did not launch) in my environment.

I'm looking forward to hearing about your further experiments. Using true ALAC
encoding sounds promissing.

Hajime, I just found a bug in someone elses code and patched it - thanks should
go to Martin and Christophe for implementing UDP in the raop sink.

Btw: My patched version of Martin's code works with shairplay (in the sense of
"it plays a song from my host remotely") but does not work with my Minx Air
200. I also have a Pioneer VSX-922 to test with. I will try that device next.

I also tried node_airtunes by Laurent Perrin
(https://github.com/radioline/node_airtunes) and it worked out of the box with
my Minx Air (did not test with shairplay yet). Its implemented in Javascript
and C++ using node.js and seems pretty mature. It uses ALAC to encode audio
frames (whereas raop_udp  just adds an ALAC header and sends PCM frames at the
moment).

I compared the RTP/RTSP/RTCP streams of both implementations (to my Minx Air
200) and found the following differences which I plan to have a deeper look on:

* raop_udp (as mentioned before) sends PCM frames with an ALAC header and
encrypts these with an AES key. If I read
http://git.zx2c4.com/Airtunes2/about/#streaming-audio-to-an-airtunes-2-compatible-server
correctly, one should either send PCM frames (with an ALAC header?) unencrypted
or encode the frames with ALAC and optionally encrypt them (as does
node_airtunes).

* Due to that (as I suspect at the moment) packets sent by node_airtunes are
much smaller (86 bytes) than those sent by raop_udp (~ 1470 bytes). As this is
close to the network MTU (at least in my setup) this _could_ be the reason why
my remote device does not play songs remotely due to network issues. UDP is
connectionless in the end. My remote shairplay box is connected to my WIFI
bridge via cabled ethernet, whereas the Minx Air 200 is connected via WIFI. As
the Minx also has a RJ-45 connector, I will try to connect it using an ethernet
cable and test again.

My next steps after testing the cabled setup would be:

1. Remove the ALAC header from the frames sent by raop_udp.
2. Use Apple's free implementation of ALAC to encode frames with ALAC before
sending if 1. does not work.

I will report back as soon as I found some time to work on this.

@Martin and Matthias,

First, thank you guys (and Christophe, of course!) for your interest and hard
work on RAOP2. I realized the same UDP port issue which Matthias described, and
wrote a patch independently.

https://github.com/hfujita/pulseaudio-raop2/commit/bcec418665ae3650471acc59b9b849cc55646843

In my patch it will first try to bind the local port, since some of the default
port might already be used by other applications, then announce that port to
the server (AirPlay device).

I'm actually not working on shairport (working on my AV receiver), but I think
we can share most of the findings.

In the first place, please accept my apologies for posting this here - I did
not find a better way to contact you.

Hi Martin,

thank you for your work on
http://repo.or.cz/w/pulseaudio-raopUDP.git/shortlog/refs/heads/raop. I followed
this bug report for about two weeks and started messing around with your
version of Christophe's code.

I also ran into the UDP socket problem: pulseaudio would connect to my
Cambridge Audio Minx Air 200 (further on: remote device) just fine and starting
to RECORD. However, as soon as the remote device sends timing packets it would
end up in an infinite loop as pulseaudio would not react on the packets sent by
the remote device. Tcpdump showed packets coming from $REMOTE_TIMING_PORT to
local ip on $DEFAULT_TIMING_PORT and IGMP port unavaible messages bouncing
back.

Digging through man pages of bind() and connect() I finally found the bug in
raop_client.c. In rtsp_cb(), lines 667 and 668 open_udp_socket() is called with
c->control_port and c->timing_port respectively. open_udp_socket() binds the
socket with port c->control_port or c->timing_port (read from MDNS) - however,
c->timing_port is the _sending_ port on the remote device. Local timing_port
should be DEFAULT_TIMING_PORT. I renamed the parameter should_bind to
local_port in the definition of open_udp_socket() and used this to bind().

With this modification, the timing packets are received correctly, timing
responses are sent and my host starts sending audio packets. There are some
errors regarding "invalid control packets" which i plan to have a look at later
on.

I attached a patch with my changes in raop_client.c. I had to reconstruct it
from my sources using vi as my IDE (Eclipse CDT) seems to have changed every
single line in the file...

Please forgive any errors in the patch as this is my first time programming in
C - I code ABAP for a living. Besides that, I am happy to help out with testing
and will report back if I see any progress.

At last, could any of you tell me how to get shairplay (or any other software)
to work (to the point mentioned above) with pulseaudio? pulseaudio does not
seem to find the MDNS entry of my local copy of shairplay. avahi_discover
reports a similar entry as that by my remote device; however, it just does not
show up in the list of available devices in the pulseaudio device list.

I would actually like to see this functionality added as well. There are many
reports across the web (reddit, arch, fedora, raspberry pi) where this is
causing issues. 

I'm willing to put up a reward for getting this done. The first developer to
get Airplay working with iOS 6 _and_ 7 gets $200 to the paypal address of their
choice.

But it must work for iOS 6 and the upcoming 7 on PulseAudio version 3.x and
4.x.

I can't talk for other maintainers, but I have zero interest in spending time
trying to implement a proprietary protocol. I don't have any AirPlay devices,
and I won't buy them either.

I'm happy to receive patches for this bug, though.

Pulseaudio 4.0 just came out. Has this been fixed? This bug has been open for
ONE YEAR, SIX MONTHS, AND 24 DAYS. I find it exhaustingly embarrassing that
this major project can't support a simple UDP stream. 

XBMC just added airplay support. But guess what. It is completely useless until
this bug is closed. You'd think the most popular music device of all time would
be able to send a stream to Pulse Audio.

NOPE. I will check in periodically on this bug. It needs attention. UDP was

I got raop_play to work with shairport (running raop_play via CLI, don't know
if the entire app is working) through a Wifi network. I posted a small patch in
the SourceForge traker a while ago :
http://sourceforge.net/tracker/?func=detail&aid=3577877&group_id=119473&atid=684238
More or less the same fix as Fernando Herrera (comment #9) proposed btw, but
different solution.

I also started to implement the UDP stuffs in a pulseaudio sink, based on
Christophe Fergeau initial work :
http://git.zx2c4.com/pulseaudio-raop2/ (Christophe code)
http://repo.or.cz/w/pulseaudio-raopUDP.git/shortlog/refs/heads/raop (Mine)

Sadly, I got a similar error in shairtunes.

[pulseaudio-tickets] [Bug 42804] raop module does not work with shairport

2013-02-20 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=42804

--- Comment #12 from Martin  ---
Are there any news on this? Maybe someone else has a sucessful test now?
Sadly there are no more changes since the initial commit of raop_UDP until now.

Beside "shareplay", also "airfoil speakers" is a listener, implemented in UDP.
Would be a great improvement if raop_UDP is working.

[pulseaudio-tickets] [Bug 42804] raop module does not work with shairport

2013-02-17 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=42804

--- Comment #11 from Fernando Herrera  ---
First, the shairport uninitialized value error can be skipped just not sending
the application/x-dmap-tagged parameter. Comment the line:

if(raopcl_set_content(raopld->raopcl, "ROAP PLAY", "Via BoBo's NAS", "")) goto
erexit;

anyway sharipoint.pl is not handling that data.

Looking at your output it seems that raop_play is not decoding anything (just a
"done" without any external decoder output). Are you trying to send an mp3
without having mpg321 installed? Yes, raop_play is bad reporting errors.

After this you should get the client sending the stream. 

Next problem is that either raop_play is sending the stream badly or hairtunes
is playing it badly. I get this:


hairtunes: hairtunes.c:363: alac_decode: Assertion `outsize == (4*frame_size)'
failed.

Commenting that assertion on shairport plays audio on the server side, however
audio quality is bad, shairpoint complaints about "overrun." and raop_play
about "ERR: raopcl_sync: read error: Connection refused".

Anyway I think this bug should be only about a pulseaudio raop udp
implementation and we should move the discussion about raop_play+shairpoint
somewhere else :)

https://bugs.freedesktop.org/show_bug.cgi?id=42804

--- Comment #9 from Fernando Herrera  ---
The garbage you are seeing in raop_play from git master is causes by a wrong
initialization secuence. The current code does:

raopcl_connectcontrol(raopcld, 6001);
raopcl_connecttime(raopcld, 6002);

but raopcl_connectcontrol starts a thread (raopcl_sync) which tries to write to
the time server socket (raopcld->tfd) which is only initialized after
reaopcl_connecttime, so it ends up writing to 0 (standard output). That is why
you see those packets on the console.

Changing the order to:

raopcl_connecttime(raopcld, 6002);
raopcl_connectcontrol(raopcld, 6001);

should fix that problem. 

But even fixing this minor problem, it is not working :)

[pulseaudio-tickets] [Bug 42804] raop module does not work with shairport

2013-02-02 Thread bugzilla-daemon
https://bugs.freedesktop.org/show_bug.cgi?id=42804

--- Comment #7 from Rune K. Svendsen  ---
I've succeeded in building the UDP version of raop-play. First I cloned from
this repo:

git://raop-play.git.sourceforge.net/gitroot/raop-play/raop-play

Then I had to make the following change to the Makefile in raop_UDP to get it
to build:

 raop_play: $(OBJS)
-   $(CC) -o $@  -lssl -lsamplerate -lid3tag -lpthread $^
+   $(CC) -o $@ $^ -lcrypto -lsamplerate -lid3tag -lpthread

It's not working with shairport though :/

This is the output of shairport when trying to play the 16 bit sample "ALAC CD
quality test" from here:
http://www.linnrecords.com/linn-downloads-testfiles.aspx

As you can see the third port DBG message is garbled. Not sure what that is
about. Could it be memory corruption?

Looking at the git log of roap-play looks quiet good, the last commit
http://raop-play.git.sourceforge.net/git/gitweb.cgi?p=raop-play/raop-play;a=commit;h=c394ae1139d90b23c2af87fbbfc58d01e480db7d
is named "Initial UDP commit".

Can anyone test it? I do not own a shairport nor airport express device just, I
am just evaluating Linux support to buy it later ...

The same issue was also reported here:

I also tried to report it upstream:
http://sourceforge.net/tracker/?func=detail&aid=3438902&group_id=119473&atid=684236

But I'm not sure if that is really the official upstream bug tracker. I didn't
got any response.

pulseaudio does not work with shairport as shairport only supports RAOP over
UDP and not TCP which PulseAudio uses. But PulseAudio should probably move over
to UDP as well, as the rest of the RAOP-world seems to use that (iOS-devices,
AirFoil etc).
