It does, however, give you more control over how indexing is done. Normally you do not need to call this function manually it's invoked automatically if necessary by Source. Indexes a number of tracks in a given source file and writes the index file to disk, where it can be picked up and used by Source. Int errorhandling = 3, bint overwrite = False, bint enable_drefs = False, bint use_absolute_path = False]) Function reference Indexįfms2.Index(string source indextracks = , If you want a progress report on the indexing, you can use the supplied ffmsindex commandline program. If you wonder why FFMS2 takes so long opening files, the indexing is the answer. This is done automatically when using Source(),īut if you want to you can invoke the indexing yourself by calling Index(), or by running ffmsindex.īy default the index is written to a file so it can be reused the next time you open the same file, but this behavior can be turned off if desired.
Image files: Most formats can be opened if seekmode=-1 is set, no animation supportīefore FFMS2 can open a file, it must be indexed first so that keyframe/sample positions are known and seeking is easily accomplished. M2TS, TS: Seeking seems to be off a few frames here and there. VOB, MPG: Seeking seems to be off by one or two frames now and then. WMV: Frame accurate(?) but avformat seems to pick keyframes relatively far away. Open-GOP H.264 will sometimes produces corruption when seeking. Transport Streams will not decode reliably without seekmode -1. Interlaced H.264 mostly works these days, but seeking may occasionally result in corruption. Because of LAVF's demuxer, most raw streams (such as elementary h264 and other mpeg video streams) will fail to work properly. DonateĬollecting weird clips from the internet and making them play takes more time than you'd think. If you are religious you may consider this the second coming. The source is MIT licensed and can be obtained from. Opens files using FFmpeg and (almost) nothing else.
