GStreamer encoding profile for the Meizu M6 player

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

RELEASE: GStreamer 0.10.26 'Think Twice'

This mail announces the release of GStreamer 0.10.26 'Think Twice'.

GStreamer is a streaming media framework that allows the construction of
graphs of elements which operate on media data.

Applications using this library can do anything from real-time sound
processing over playing video to capturing audio, video, and even other
types of media data. Its architecture allows for adding new data types
or processing capabilities simply by installing new plug-ins.

GStreamer is the core module, containing libraries, headers, the basic
object hierarchy, and a set of media-agnostic core elements.

I tried to change the flags (and checked with the logs that I had 
changed the correct bytes), but it didn't work. About the bugs, I think 
I'll open them all at once, once this is resolved and I know exactly if 
this has an impact or not.

Couldn't test this one, I have difficulties in finding the right bytes 
to modify.

Replaced the "dmlh" by "JUNK", didn't work either.

For these modifications, I created the corresponding binary diffs with 
bsdiff, so once I'll fiund the right places to change, I'll easily be 
able to test all the combinations.

Slide show with music interspersed with short videos

Hello,
  I'm looking for a Linux/Gnome app that will play a playlist containing
music and videos.  I'd like to show photos as a slideshow while the
music is playing.

Totem is close in that it will cope with a playlist including music and
video.  It plays Goom or whatever while music is playing and interrupt
that while a video is playing but I can't find a slideshow plugin.

Is there anything out there?

Huge regards,

Owen.
