https://github.com/FFMS/ffms2/blob/mast ... ursynth.md

代码: 全选

AVI, MKV, MP4, FLV: Frame accurate
WMV: Frame accurate(?) but avformat seems to pick keyframes relatively far away
OGM: Frame accurate(?)
VOB, MPG: Seeking seems to be off by one or two frames now and then
M2TS, TS: Seeking seems to be off a few frames here and there
Image files: Most formats can be opened if seekmode=-1 is set, no animation support


试试L-SMASH或者ffms2000吧。

我试的这些wmv文件 用lsmash
src = core.lsmas.LWLibavSource(r"F:\123\1.wmv",threads=1)
都会报Python exception: lsmas: failed to construct index.

ffms2000跟ffms2都是ffms.dll这个文件么
在第2个链接里面下载了ffms.dll
src = core.ffms2.Source(r'F:\123\1.wmv',threads=1)
压完还是少了5秒

回到 “VapourSynth”
