MPEG muxer (-mpegopts) †
The MPEG muxer can generate 5 types of streams, each of which has reasonable default parameters that the user can override. Generally, when generating MPEG files, it is advisable to disable MEncoder's frame-skip code (see -noskip, -mc as well as the harddup and softskip video filters).
format=<mpeg1 | mpeg2 | xvcd | xsvcd | dvd> †
stream format (default: mpeg2)
size=<up to 65535> †
Pack size in bytes, do not change unless you know exactly what you are doing (default: 2048).
muxrate=<int> †
Nominal muxrate in kbit/s used in the pack headers (default: 1800 kb/s). Will be updated as necessary in the case of 'format=mpeg1' or 'mpeg2'.
tsaf †
Sets timestamps on all frames, if possible.
(no)reorder †
Enables the frame reordering code, that stores frames in decoding (rather than display) order (de- fault: disabled). Use it only if you believe the video frames in the original stream were stored in- correctly. Works only with MPEG-1/2 video.
init_vpts=<100-700> †
initial video pts, in milliseconds (default: 200)
init_apts=<100-700> †
initial audio pts, in milliseconds (default: 200)
vdelay=<1-32760> †
Initial video delay time, in milliseconds (default: 0), use it if you want to delay video with respect to audio.
drop †
When used with init_adelay the muxer drops the part of audio that was anticipated.
vwidth, vheight=<1-4095> †
Set the video width and height when video is MPEG-1/2.
vpswidth, vpsheight=<1-4095> †
Set pan and scan video width and height when video is MPEG-2.
vaspect=<1 | 4/3 | 16/9 | 221/100> †
Sets the aspect ratio for MPEG-1/2 video.
vbitrate=<int> †
Sets the video bitrate in kbit/s for MPEG-1/2 video.
vframerate=<24000/1001 | 24 | 25 | 30000/1001 | 30 | 50 | 60000/1001 | 60 > †
Sets the framerate for MPEG-1/2 video. This option will be ignored if used with the telecine option.
telecine †
Enables soft telecine mode: the muxer will trick the video stream so as to make it look like encoded at 30000/1001 or 30 fps; it only works with MPEG-2 video when the output framerate, eventually con- verted with -ofps, is either 24000/1001 or 24 fps. Any other framerate is incompatible with this op- tion.
