Usage
FFMpegSource(string source, int track = -1, bool forceseek = false)
FFmpegSource(string source, int track = -1, bool forceseek = false)
source: source file
track: video track nubmer as seen by the relevant demuxer, must be a video track
negative values means the first found video track
forceseek: seek even if the format has no registered index, only useful for containers with limited avformat support
Compatibility
AVI, MKV, MP4, FLV1: Frame accurate
AVI, MKV, MP4: Frame accurate
OGM: Messed up first frame and seeking produces smearing with forceseek=true, incredibly slow seeking without
WMV: No seeking
VOB: No rff flags, otherwise it appears to work
