GStreamer encoding profile for the Meizu M6 player

[Luis Menina <liberforce freeside fr>]

Hi list !

I'm still investigating on why videos encoded with gstreamer fail to 
play on my Meizu M6 digital player, while converting them with mencoder 
works.

I had since last time [1] tried to generate with gstreamer :
- avi files with a video stream only (no audio stream)
- avi files with an audio stream only (no video stream)
...but they all failed to play too.

So I tried something else : creating a sample file with gstreamer with 
only a video stream, and encoding the file with mencoder with direct 
copy of the video stream.

The fast is that the video produced by mencoder, and based on the 
gstreamer-generated one, works ! As the video stream was untouched 
during the process, that means IMHO that the container is the one at 
fault here.

You can generate the gstreamer test file with this command :
gst-launch-0.10 videotestsrc num-buffers=100 ! 
'video/x-raw-yuv,framerate=(fraction)20/1,width=320,height=240' ! 
videoflip method=clockwise ! xvidenc bitrate=384000 max-bframes=0 ! 
queue ! avimux name=mux ! progressreport ! filesink location=gstreamer.avi

Then, you can generate the mencoder test file with this command :
mencoder gstreamer.avi -ovc copy -o mencoder.avi

You'll find attached both logs generated (and cleaned up a bit) with the 
following syntax :
GST_DEBUG=avidemux:3,riff:3 gst-launch-0.10 playbin2 uri=file:///.....

But you may prefer read directly the attached diff.log file, containing 
the diff of both files, and showing the fields that are different 
between both avi files.

I'd be grateful if someone could tell me which field causes the problem, 
or how I can change those fields values. Even just knowing if the 
problem comes from the firmware of my player or from gstreamer would be 
useful !

Thanks in advance,
--
Luis
