• Hardware decoding will now by default automatically fall back to CPU decoding if no suitable hardware decoder can be found, note that if anything else goes wrong it is still considered an error, tis behavior can be controlled with the hwfallback argument
• The maxdecoders argument has been added to make it possible to reduce the number of concurrent decoder instances used to conserve memory (4x4k h.264 decoders with max reference frames can use up to 1GB of memory total in addition to the internal cache)
• Default internal cache size is reduced to 100MB for video decoding
• Improved framerate guessing code to handle even weirder cases
• Fixed seeking performance for CFR h.264 in AVI and possibly others
• Index files are now by default stored in $XDG_CACHE_HOME/bsindex when not running on windows
