* Override mp3 remux container
The server generally filters out invalid containers for HLS in most cases. However, MP3 is a special case because, while it is technically possible and allowed as a codec for fMP4 on the server side, most browsers do not support it. Override the remux container to force MPEG-TS for MP3. The server will still direct play MP3 in an MP3 container. This is useful for supporting universal containers like MKA.
* Fix lint

The previous check was too naive, assuming that most browsers that support playing MP3 directly in an mp4 file can support MP3 with HLS. However, this assumption is wrong. In fact, most browsers won’t play MP3 with HLS, with Safari being the only exception. Even on Safari, MP3 support with HLS is limited to the mpegts container, and it won’t play MP3 in the fmp4 container.
The current container setting was set 4 years ago and does not reflect current browsers. We should prioritize using fmp4 when possible and fallback to mpegts if necessary.
AV1 should be supported by Apple devices that support hardware
acceleration. Software decoding is not yet supported on Safari.
