• avaudiodec: fix playback issue with WMA files, would throw an error

at EOS with FFmpeg 5.x

• Fix input buffering capacity in live mode for aggregator,

video/audio aggregator subclasses, muxers

• glimagesink: fix crash on Android
• subtitle handling and subtitle overlay fixes

• Miscellaneous bug fixes, memory leak fixes, and other stability and

reliability improvements
