[FFmpeg-devel] [PATCH] libavformat/cdg: unset duration on packets

[Guillaume Desmottes]

CDG doesn't ensure a constant framerate as we can have holes in the CDG
stream. So there is no guarantee of the duration of a single frame, it
will be displayed until a new packet with CDG instruction arrives in the
stream.
