MPEG-4 ASP video stuttering
Posted: 19 Dec 2005 12:59
I recently made an Xvid ASP encode with mencoder which causes "stuttering" in VLC. Mencoder tested was CVS20050928 and CVS20051102. I have tested the clip on 0.8.4 for Windows and OSX, as well as 0.8.5-svn-20051217. The clip plays flawlessly with Media Player Classic 6.4.8.6 using ffdshow 20051208-gcc4.0.2-sse-x264. Besides the MP4 container (muxed with MP4Box) I also tested AVI and MKV, but the video still stutters. I have also tried various encoding parameters (no B-frames, reduced quality), but to no avail.
Please take a look at the clip and report your findings:
