--- Comment #9 from Gregoire <gregoire at gentil.com> ---
Last important comment, I need libav to play the file WITH hardware
acceleration on Gstreamer1.5. I'm 100% that it's hardware decoded. It seems
that Libav is only used for a deinterlace plugin.
Without libav on Gstreamer1.5, there is no error but the playback is completely
jerky.
Here is a comparison of the dumpelements between Gstreamer 1.5 with and without
libav:
DUMPELEMENTS: inputselector1 uridecodebin1 decodebin0
amcvideodec-omxqcomvideodecoderavc1 capsfilter1 h264parse1 multiqueue1 qtdemux1
typefind source playsink vbin vconv conv2 videobalance scale conv identity
vqueue glimagesinkbin0 sink glcolorconvertelement0 gluploadelement0 vdbin
vdconv streamsynchronizer0
DUMPELEMENTS: inputselector1 uridecodebin1 decodebin0
amcvideodec-omxqcomvideodecoderavc1 capsfilter1 h264parse1 multiqueue1 qtdemux1
typefind source playsink vbin vconv conv2 videobalance scale conv identity
vqueue glimagesinkbin0 sink glcolorconvertelement0 gluploadelement0 vdbin
deinterlace vdconv streamsynchronizer0
The only difference is the presence of deinterlace in-between vdbin and vdconv.
