Do not prefer an unsupported audio stream (iPhone 16)

[clsid2]

Sample file: https://www.sendspace.com/file/5p09hb

Video recorded by iPhone 16. It contains two audio streams: AAC and apac (not yet supported by FFmpeg?).

The splitter selects the second track by default causing audio playback to fail. Turning off option to prefer best quality track solves that. But a better fix perhaps would be to ignore unknown/unsupported audio formats in the best track selection choice. Or just ignore this specific format if that is easier.
