Ok, it seems MP4V video stream is not handled well. Even with --no-audio
nvgstplayer drops a lot of frames in this 352p movie.

Thanks! --no-audio gave 25fps without dropping a single frame in the 720p
Big Buck Bunny movie trailer that has a H264 video stream.
nvgstplayer -i trailer_720p.mov --no-audio --stats

Any workarount to obtain full fps, plus the audio?

BTW I notice that the scaling of the video is not smooth, you can see the
enlarged pixels everywhere for small definition videos or the jagged
borders for big definition videos.
Have anyone else noticed that?


Best, Nico
