0.74

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)

0.73.1

0.73.1 - 2018/10/11
LAV Video

• Fixed: Container-provided color information will only overwrite video bitstream color information if its set and valid

LAV Audio

0.73

0.73.0 - 2018/10/05
LAV Splitter

0.72

0.72.0 - 2018/06/19
LAV Video

• Changed: Enabled CineformHD decoding by default, since the decoder has much improved
• Fixed: Decoding Matroska files with Linked Segments which used old x264 4:4:4 encodes could result in corruption

LAV Audio

• NEW: Blu-ray Dolby Digital Plus 7.1 decoding and bitstreaming support
• NEW: LAV Audio will fallback to audio decoding if bitstreaming is not supported by the audio renderer/hardware
