0.74.1 - 2019/03/19
LAV Video
- Fixed: VP9 video could produce wrong timestamps, resulting in a black screen or other playback disruptions
- Fixed: Decoding VP9 from a non-keyframe (ie. after a seek, or badly cut file) would not always recover properly once a keyframe was encountered
0.74.0 - 2019/03/16
LAV Splitter
- Changed: Using GnuTLS for HTTPS and other TLS protocols, improving performance and compatibility with a lot of web streaming services (ie. YouTube Live Streams through youtube-dl, and more)
- Fixed: Keyframes in MP4 files were being reported with a slightly offset timestamp, resulting in slow keyframe seeking
- Fixed: Subtitles that stretch over chapter boundaries could be lost in Ordered Chapter MKV files
- Fixed: Fonts embedded in MKVs without a proper mimetype were not being imported (now it checks the file extensions for .ttf/.otf as well)
