Our pipeline

gst-launch-0.10 filesrc location=/mnt/usb/301869/L2.0_320_176.mp4 typefind=true ! aiurdemux name=demux demux.video_000000 ! queue ! vpudec ! mfw_v4lsink demux.audio_000000 ! queue ! aacparse ! beepdec ! alsasink -v

Attached gst_debug log of Vpudec.

It is not reproducing always. On repeated playback we observed sometimes.

If we enable gstreamer debug log, we are able to reproduce always.

We are using gst-fsl-plugins version 3.5.7 and gstreamer version 10.36

Result of "uname -a" is

Linux freescale 3.0.35-2154-g94689e1 #180 SMP PREEMPT Wed Mar 4 15:24:49

CST 2015 armv7l GNU/Linux

BSP version is 3.0.35 based customized BSP.

Board is IM6D based customized board .

This is very urgent, for a production program. SOP is very close.

Please help us analysing this ASAP.

Thanks and Regards:

Hi ramakrishnakamath ,

From the log can't see avaliable information to locate the root cause, could you use gplay to play on your board? How about the log when export GST_DEBUG=GST_ELEMENT_FACTORY:3? could you share the normal playback log?

By the way , could you share the video clip, then we can try to reproduce on our side.

best regards

Jack

Hi,

Please tell me what is difference in playbin2 and our pipeline? We are using elements used by playbin2 only.

We will try and update to you if we are able to reproduce this with playbin2.

I got log of both scenarios. Please let me know where can i upload files to send you?

Thanks and regards,

Ramakrishna Kamath

Hi Ramakrishna Kamath

playbin2 will select the gstreamer plugins to constrcut a pipeline automatically by Rank value, commonly, freescale plugin has the highest priority. Your pipeline plugins are selected by your self, some plugins maybe not has the highest priority.

By the way, I can't access your video clip, could you find a netdisk and upload it and tell me to download it?

best regards

Hi Ramakrishna Kamath,

How many times will you reproduce this issue when use playbin2 by repeat mode? Could you check to play with GST_DEBUG=GST_ELEMENT_FACTORY:3 and share log?

I use your video clip and play repeatly more than 20 times, can't reproduce the issue.
