Re: [E-devel] Any Improved Pulseaudio support for Mixer planned?

[Flávio Ceolin]

I'm using the same edj of the current mixer, so  it looks exaclty the
same, but i intend to replace the label with the channel name with a
toggle to become easy change the volume of any output. The config
dialog was replaced by a standalone application similar the
pavucontrol (with less functionality). The cool thing is that the
default output is gotten from pulseaudio exaclty as gnome-applet (and
probably the kde mixer) does, so we'll have the same behaviour on E.

I intend to publish it, at the moment i've a mixer like pavcontrol
that makes possible change volume and redirect streams for different
sinks (outputs).
As Gustavo said, it was done integrating the pulseaudio with ecore
mainloop. The applet for E is not finished yet. I just need few days
to clean the code before push it.

Sorry, my mistake. I forgot to change the version of elocation for the
elementary.pc.
It should be fixed now (revision 81142).

Hi, I've already committed because k-s needs it to keep his work in
the efl tree build system. As he's changing a lot the build system and
intends to simplify the options we agree that the best option should
be commit it and then working in the possible errors.

The main reason to support it, it is what raster said, add and remove
support for engines without need rebuild the libecore_evas. It's also
pretty good for the packagers because they don't need build with many
engines enabled by default increasing the number of dependencies.

[E-devel] Ecore_Evas engines

[Flávio Ceolin]

Hi folks,

I have recently committed in IN-EFL/ecore some patches implementing
support for loadables modules. It makes the engines been loaded when
they are needed. I did not break the api, so each engine still has its
own api. It's far from ideal, should exists one api used by all the
modules but at least until the next version, we need keep the api.

The modules (engines) usually exports just on symbol, the "new"
function, the other necessary functions are in the engine's interface.

Some points to considerer:

1) I've tested the engines that i'm able to build, which means, sdl,
(opengl,software)_x11, buffer, wayland_(egl,shm). Windows, wince,
cocoa and ps3 i do not even built.

2) I've commited in the IN-EFL to someone working with one of these
engines try to build and possibly report to me the problems.

3) Engines such as (software,opengl)_x11 are been build in just one
module initially and exporting the "new" functions and interfaces
necessary.

4) I'm working to port it to new efl tree (expending more time and
been more careful) with the build system. If no one oppose i'll commit
it soon.

5) I break the build between the commits, i did it to make easier
understand how the engines were ported

Best Regards,
Flávio Ceolin

Yep, initially yes, but it's possible create support for multiple
points using this api, I know that is worse in both cases performance
and precision of interpolation.

It's easier make this code upstream first and then extend it for
support multiple points than the opposite.

[E-devel] ecore-audio and pulseaudio

[Flávio Ceolin]

Hi folks,

I've been working with pulseaudio for while and now we've implemented
audio envelopes in PulseAdudio. The code is not upstream yet, but it
can be found in this repository
(http://git.profusion.mobi/cgit.cgi/ceolin/pulseaudio/) (branch ramp).

Using this code is pretty simple, for example, to apply an envelope on
a sink pa_context_set_sink_volume_ramp_by_index, to apply on a
sink-input (stream) pa_context_set_sink_input_volume_ramp.

The audio envelope works in the follow way, the user states the final
volume, how long this envelope should last and the interpolation type
(which can be, cubic, logarithm or linear). In the internals
PulseAudio figures out how many samples are in the estipulated
interval and then using the interpolation type chosen it changes the
samples volume until the volume desired. The difference between apply
an envelope on a sink or sink-input is that when using over the sink
the envelope is applied in all streams of that sink.

Some feedback from people (Daniel :) ) working with ecore-audio would be great.

Flavio Ceolin

Besides the problem with the main_loop pointed out by raster, i've
found some small issues in the patch. I've attached your patch with
the review. Overall, the patch is working properly :)

 No, never do this.

 One should have a global setter and maybe a getter to enable or disable
 features, or even better just load multisense if it's required.

 [Prince] Multisense load is not needed during
 compilation/decompilation, because it inculdes remix and its
 plug-in(i.e. eetsndreader, ALSA) load, which are specificaly
 required during runtime only.
 As per your suggestion above, should we add interfaces for
 setter/getter to enable this feature in edje ? Please share your
 opinion.

I've tested in rev 72117 and now 72400 in both the problem happened. I
built with these options:
/configure --enable-tests --enable-build-examples --enable-multisense
CFLAGS=-Wall -g -O0

As for the patch, I took a look in it and I would like to understand
some points.

+static void
+pa_player_playbuffer(RemixEnv *env __UNUSED__, PA_Player_Data
*player, RemixPCM *data, RemixCount count)
+{
+   int ret;
+   RemixCount i;
+   RemixPCM value;
+   size_t length;
+
+   length = count * sizeof(RemixCount);

Shouldn't it be
length = count * sizeof(RemixPCM);

+
+   for (i = 0; i < length; i++)

Shouldn't check if length is greater than the size of the buffer ?

+ {
+value = *data++ * (player->max_value);
+*(player->playbuffer + i) = (PLAYER_PCM) value;

With this cast we are discarding part of the data, is it ok ?

+ }
+
+   ret = pa_simple_write(player->server, player->playbuffer, length,
&player->error);
+
+   if (ret < 0) WRN("pa_simple_write() failed: (%s)",
pa_strerror(player->error));
+
+   return;
+}

I' ve found a segfault when running edje_player (multisense example,
multisense.edj), you could check it in the attached file.
It's valid you know that this problem is not happening when running
the edje-multisense's example.
Also, I didn't understand the point 5 (edje can compile without
availability of remix).
As far as I could see there is no way to build multisense without
libremix right ?

Hi folks,

I bring bad news, I've found other problems with emotion. They are:

1) position_set when the emotion is paused
   If you do a position_set with the emotion paused and then do
position_get it'll
   return the old position.

2) pause the video before the "open_done" or "length_change" is not working.

Re: [E-devel] Problem with ecore_con_url

[Flávio Ceolin]

Well, the problem is that my libcurl was build with the flag
--enable-threaded-resolver
and during the resolve phase there's no fd to wait on.
As fair as I know, the libcurl package in, at least gentoo, fedora and
arch, is using this flag.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes

[E-devel] Problem with ecore_con_url

[Flávio Ceolin]

Hello efl developers,

Trying to use ecore_con_url I wrote a simple test (file in attached)
but ecore_con_url_get is failing.
Digging into the code I figured out that the function curl_multi_fdset
(in the ecore_con_url.c:1769) sets fd_max to -1 then ecore_con_url
cannot set up a fd_handler.
I also tested ecore_file_download_example.c and the same is happening.

Someone knows what is the matter ? My curl version is 7.21.7 and my
efl revision is 60739.

I'm sending two patches for the elm_genlist (they are very similar to
the patch for the elm_list).

Like the first mail, one patch is just to add a simple test in the
elementary_test the other one contains the functionality itself.

Furthermore it is very easy to add these signals if necessary in the future.

[E-devel] Swipe event for the elm_list

[Flávio Ceolin]

Hello,

I have done a patch to add a new event for the elm_list similar to the
iphone swipe's effect.
The event is quite simple, it's triggered when a horizontal drag plus
mouse release occur.

There are two patches, the first is the feature itself and the second
is just two examples for elementary_test.
