Thank you,
I updated GStreamer to version 1.6.1 and applied patches from Nicolas
(https://bugzilla.gnome.org/show_bug.cgi?id=733864).
This resolved the issue witch "CODA PIC_RUN timeout".
At the moment situation looks a little bit different:
1. Playing flv videos (video codec: Sorenson Spark Video) allows me to
play multiple videos and EOS message is received.
2. Playing h264 videos with lower resolution runs smoothly (no CODA
PIC_RUN timeout) but when video reaches it's end - no message is
reaching the qt application and thus I can only stop it manually.
* Is there a resolution of this problem with missing end-of-stream
detection?
3. When playing h264 videos in HD resolution (tested with
big_buck_bunny_1080p_h264.mov) the problem with "CODA PIC_RUN timeout"
still occurs with small difference - when I press STOP "CODA PIC_RUN
timeout" messages don't show up anymore while before they were showing
up repeatedly (every second) until my qt application stopped.
- Another strange behaviour is that after I get "coda 2040000.vpu:
failed to allocate bitstream ringbuffer" message -> the video starts
running again (when I press PLAY) and it starts detecting end-of-stream
(!) - see attached file

That shouldn't happen anymore in recent kernels. In the past, repeated
reqbufs calls would leak buffers because the cleanup was only done on
close.
Dear Phillip,
Unfortunately I'm using i.MX6 device so kernel provided by Freescale is
v3.14 and I am using kernel provided by Phytec company which is based on
mainline but the newest version is 3.19 and I cannot upgrade it.
I have already came upon some patches you provided:
starting with
https://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg77439.html
and another pack starting with
http://www.spinics.net/lists/linux-media/msg91575.html
but I think that some of these are dependent on other components like
e.g. "[PATCH 07/10] [media] coda: drop custom list of pixel format
descriptions".
* Is there a possibility for you to give me a list of patches to apply
(and maybe dependent packages) so I can try to apply them manually?
I hope it's not too much too ask..
Best regards
Piotr Lewicki

The video is stopped but I can see last frame on the screen although in
qt application it should receive end-of-stream message and stop the
video (resulting with black screen).
Looks like the coda driver is constantly fed empty buffers, which don't
increase the bitstream payload level, and the PIC_RUN times out with a
bitstream buffer underflow. What GStreamer version is this?
I believe this is side effect of how the MFC driver worked in it's
early stage. We had to keep pushing empty buffer to drain the driver.
So GStreamer still poll/queue/poll/queue/... until all capture buffers
are received. I notice recently that this behaviour can induce high CPU
load with some other drivers that don't do any active wait when a empty
buffer is queued. I would therefor suggest to change this code to only
push one empty buffer for your use case. An submitted patch to support
CMD_STOP can be found here, though is pending a re-submition by it's
author.

For proper EOS detection with CODA driver (using EPIPE return value),
you indeed need GStreamer 1.6+.
cheers,

QML debugging is enabled. Only use this in a safe environment.ny_1080p_h264.mov
QEglFSImx6Hooks will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
