Re: [linux-dvb] linux-dvb Digest, Vol 35, Issue 16
Hi Christian,
it seems like you have broken usb controller hardware, search the
em28xx mailinglist for crash and em28xx, someone also had the same
problem earlier already I think!
Hi,
thanks for the hint, and I am apparently running into exactly the same
problem, as the patch on the em28xx list helped.
drivers/usb/host/ehci-hcd.c:611
/* complete the unlinking of some qh [4.15.2.3] */
if (status STS_IAA) {
if (ehci-reclaim) {
COUNT (ehci-stats.reclaim);
ehci-reclaim_ready = 1;
bh = 1;
} else {
printk(KERN_ERR AUA: ehci reclaim NULL status: %u\n, status);
}
}
I see now in dmesg
AUA: ehci reclaim NULL status 32
But the DVB stick works. Thank you for the great work.
I will try to follow up in the usb-dev mailing list nevertheless.
Chris

All :-)
Sioux is back :-)
I see my email has generate a big work...
Thanks guys
I am happy... even if I hope none of you will get money for that becouse
otherwise I want some cents for me too. :-)
and also I hope no RIAA or SIAE or any yellow finace police in futures
days will ring to my door for have done only few stupid testing and
report on this mail list :-)
So,
Hermann give me instruction what I have to do for test the patch you
sent me like:
1. what I have to type on my keyboard to test the file you sent (how I
install that)?
2. what you need for my signed-off?
I told you I am not a developer... just a crazy sioux...
Before start the test I must clean some alias.
Ciao.
P.S.
I don't like give you my signed-off with my real name :-) if ok I can
do it with my nick name..
that's ok for you?

Hi,
OK, seems we have enough rules and documentation now.
Based on what I seem to know about the card and is prior in this thread
on the linux-dvb ML, the patch is correct. Some spaces, also between
braces, are introduced by checkpatch.pl. Please review.
Sioux, please test and check and Sign-off with me or take at least some
credit for your work on it.
Cheers,

- saa7134: add Twinhan Hybrid DTV-DVB 3056 PCI
- Thanks go to Sioux for providing code and asking to fix the auto
detection.
- S-Video seems to be untested and likely a Composite over S-Video
input is also there. The remote is not yet investigated.

Hi Sioux! Am Samstag, den 08.12.2007, 22:16 +0100 schrieb sioux: All :-) Sioux is back :-) I see my email has generate a big work... Thanks guys Not much work to set up some lines and you had all ready so far. It takes more time to look up the latest known status on the lists. In this case, we had to start also to look for coding style issues running seven years old code against a script and I was not sure if I have to fix all what comes up over all places, when submitting some new lines ... (then I ask also, who took it previously?) I am happy... even if I hope none of you will get money for that becouse otherwise I want some cents for me too. :-) and also I hope no RIAA or SIAE or any yellow finace police in futures days will ring to my door for have done only few stupid testing and report on this mail list :-) No money and totally legal. So, Hermann give me instruction what I have to do for test the patch you sent me like: It's your patch suggestion with the fix for the auto detection you asked for and taking Egidio's previous test report into account. 1. what I have to type on my keyboard to test the file you sent (how I install that)? If you have a recent v4l-dvb snapshot from the master repository at linuxtv.org, put it into it and name it, say, sioux.patch. patch --dry-run -p1 sioux.patch If no error. patch -p1 sioux.patch make make rmmod make rmmod make install modprobe -v saa7134 Check if the auto detection does work and test all you can, analog TV, digital TV, radio and the other inputs. Report what you can't test and what goes wrong and maybe needs further fixes. 2. what you need for my signed-off? You have the link to read about it. No fake allowed. Just a line Signed-off-by: your_name your.e-mail.somewhere I told you I am not a developer... just a crazy sioux... Before start the test I must clean some alias. Ciao. P.S. I don't like give you my signed-off with my real name :-) if ok I can do it with my nick name.. that's ok for you? I don't make the rules, not even Linus, some gambling in the markets force us to take care to document our code. For just adding a new card it might be a bit too much currently ... See above and read. It is up to you. If you don't like it, you get at least credit as Sioux. Happy testing, that is the work now.

[linux-dvb] H.264 DVB-T support for dvb-utils and w_scan
DTT tests have just started here in NZ and they are going to be using
H.264 for the video signal. Using the existing builds of dvb-utils-1.1.1
the video PIDs don't appear in the channels.conf because they are using
0x1b for the video stream type.
If I dump the PMT for one of the channels using dvbsnoop it contains the
following info
Stream_type: 27 (0x1b) [= AVC video stream as defined in ITU-T Rec.
H.264 | ISO/IEC 14496-10 Video]
reserved_1: 7 (0x07)
Elementary_PID: 514 (0x0202)
reserved_2: 15 (0x0f)
ES_info_length: 16 (0x0010)
DVB-DescriptorTag: 82 (0x52) [= stream_identifier_descriptor]
Descriptor_length: 1 (0x01)
component_tag: 5 (0x05)
MPEG-DescriptorTag: 14 (0x0e) [= maximum_bitrate_descriptor]
Descriptor_length: 3 (0x03)
reserved_1: 3 (0x03)
maximum_bitrate: 16050 (0x3eb2) (= 802500 Bytes/sec)
MPEG-DescriptorTag: 2 (0x02) [= video_stream_descriptor]
Descriptor_length: 3 (0x03)
multiple_frame_rate_flag: 0 (0x00)
frame_rate_code: 3 (0x0003)
MPEG_1_only_flag: 0 (0x00)
constrained_parameter_flag: 1 (0x01)
still_picture_flag: 0 (0x00)
MPEG-DescriptorTag: 6 (0x06) [=
data_stream_alignment_descriptor]
Descriptor_length: 1 (0x01)
alignment_type: 2 (0x02)
as VideoStream: (= video access unit) as AudioStream:
(= reserved)
At present the tools scan/dvbscan and w_scan assume that the video has a
stream type of 0x01 or 0x02.
For dvb-utils the following diff will provide H.264 scan support
--- linuxtv-dvb-apps-1.1.1.orig/util/scan/scan.c
+++ linuxtv-dvb-apps-1.1.1/util/scan/scan.c
@@ -755,6 +757,7 @@
switch (buf[0]) {
case 0x01:
case 0x02:
+ case 0x1b: /* H.264 video stream */
moreverbose( VIDEO : PID 0x%04x\n,
elementary_pid);
if (s-video_pid == 0)
s-video_pid = elementary_pid;
In the case of the tool w_scan a similar line is needed in the function
parse_pmt.
