Mencoder b-frame question
Hi, I am a newbie who just started to learn how to encode about 2 weeks ago. Everything seems OK but when I try to use B-frame, there is stuttering produced (but nothing wrong in mplayer).
I cancel all options except b-frame in this video. mencoder Robotica_1080.wmv -o test.mp4 -nosound -ovc x264 -x264encopts bitrate=1350:bframes=1:level=41:global_header:keyint=150 -vf scale=640:-2,expand=aspect=16/9 -fps 24000/1001 -of lavf Please help me -- Video source: http://download.microsoft.com/downlo...otica_1080.exe |

MEncoder displays this warning for a reason, I think
Code:
** MUXER_LAVF ***************************************************************** REMEMBER: MEncoder's libavformat muxing is presently broken and can generate INCORRECT files in the presence of B-frames. Moreover, due to bugs MPlayer will play these INCORRECT files as if nothing were wrong! ******************************************************************************* x264 does write proper MP4 and MKV files.
