Dear Maintainer,

After upgrading to this version, handbrake appears to have lost the ability to detect and use Vorbis-encoded audio in source files. When opening such a file it pauses (breifly for small files, longer for large files) and eventually presents an audio-free processing environment. The Add button also fails to add the audio track. A source file with MP3 audio encoded works as expected.

Re-coding media with another program to use high-bitrate MP3 then re-passing it through Handbrake for final compression also works.

Thank you for looking into this matter.
