[gst-devel] Gstreamer 264 problem

[Zixia Huang]

Thanks Tim.

I tried byte-stream=true. Now the saved 264 stream can be played using
ffmpeg.

However, it seems that now ffdec_h264 in gstreamer cannot correctly decode
the stream from x264enc when byte-stream is set to true.

So my question now becomes how ffdec_h264 can correctly decodes the stream
either from x264enc (when byte-stream=true) or from a 264 file encoded using
libx264?

Thanks,
Zixia
