Can not play avi video on DM355

Where did you get or how did you generate the AVI file?  DM355 MPEG4 decoder is not a universal decoder; therefore it cannot decode any MPEG4 video file.  It can decode MPEG4 video file encoded in DM355 itself or an MPEG4 stream that has been processed via ArcSoft MediaConverter tool (a few forum posts exists on this such as http://community.ti.com/forums/p/935/6791.aspx#6791)

It's e regular movie file, that I converted to mpeg4 avi using the ArcSoft's MediaConverter. Is it possible at all to convert any media file in DM355 playable format?

Yes, this should be possible, though I have not personally tried it (on my todo list).  May I ask where you got the gstreamer port from?

As I mentioned above, it is gst-ti-plugin-full-0.99.00.tar.gz, downloaded from https://gstreamer.ti.com/gf/project/gstreamer_ti/frs/

Thank you for the clarification; we have had a few gstreamer ports available for our DaVinci processors, but the one above from gstreamer.ti.com is the one I would recommed people use going forward.  I should also mention that this port will be supported via community and forums available at gstreamer.ti.com, with additional engineering services available from RidgeRun (TI third party) for a fee.  Diego from RidgeRun is a regular poster in this community and should be able to offer more details. 

Hi Juan,

Yesterday I obtained the MediaConverter tool from TI. I converted several movies to MPEG4 avi-files, but none of them could be played by gsreamer on dm355:

# ./decode_avi.sh -f /opt/media_demo/mc-sample_mpeg4.avi

gst-inspect mad
gst-inspect osssink

Obviously the problem is not in gstreamer, because it plays normally avi-files, muxed with ffmpeg from mpeg4 video stream for dm355 and mp3 audio stream.

Any Ideas?

To be honest, I have not tried MediaConverter tool myself, but I agree the problem seems to be with the stream itself, which means AVI file (I assume produced by MediaConverter) is not quite right.  I know there are others in this community that have requested MediaConverter tool so maybe one of them can chime in and share the lessons they have learned.  I would also search the community as I believe there are a couple of long threads on this subject.

Well, there is a solution.

Now gstreamer can play avi files processed with the MediaConvertor.
