Much thanks for this valuable information.

Because I want to add several audio streams to a MP4 video, I'm looking for an audio codec, with optimal compression. As AAC in my context needs 128 kb/s, but Vorbis only 90 kb/s, I thought, it was a good choice.

Which audio codec you would suggest, which has a wide range of compatibility, except AAC?

Maybe Opus?

For the video I want to use HEVC.

Is there a possibility to encode AAC_HE with FFmpeg and would it make sense?
