  • Allow to have multiple transmuxers, but choose only the one that is valid depending on whether it supports the codecs or not
  • Supported codecs: AAC, AC-3, EC-3, H.264, MPEG/MP3
  • It is prepared to allow more codecs in the future (HEVC/H.265) (no muxed)

I did not find any public streams with MPEG-TS and AC-3 or EC-3. But I tested it in private.

We need to both review this and investigate test failures on Safari.

The Safari and ChromeMac failures look new, but the Tizen ones look like the same flaky tests we have yet to resolve in main.

It's interesting that it doesn't happen on GitHub's Mac VMs, though.

Is an explicit packet length invalid for video? Why wouldn't you just account for an explicit packet length in subarray() below?

It's a design issue, because there are video nalus packages that may overlap with other PES.
