[Ffmpeg-devel] [PATCH] Fix A/V sync in some NSV files

The NSV demuxer currently assumes that a video frame's timestamp  
increases by one on each frame, but some low-bitrate NSV files omit  
video frames for some NSV frames, and expect the timestamp to  
increase by one every NSV frame. This is most noticable in http:// 
samples.mplayerhq.hu/nsv/64vp3.nsv where the video runs several times  
faster than the audio. The attached patch fixes this by  
unconditionally incrementing the video's timestamp with each NSV frame.
