Local HTTP output stream - no sound

[krzemin]

Hi! Thank you for keeping this awesome piece of software alive!

I was trying to play output http stream, but unfortunately it doesn't work as intended - there is no sound being played.
I tried both FLAC and OPUS stream. While the playback is active, it periodically prints HttpStream updateStatus 1 1 output.

MacOS ➤ ./Cantata -d http-stream

I use MacOS 14.5, but on my second Linux machine similar issue appears (I can provide logs from the other machine as well if needed).

Both http output streams are directly produced by MPD flac/opus encoders, reverse-proxied by nginx. They play fine in other players (mpv, vlc).

There were a lot of changes to QtMultimedia API in Qt6 and I wasn't able to fully check if it still works. This is probably a result of the migration and I will need to take a look as to what exactly changed.

The linked PR should fix the audio output. There might still be edge cases, but I will merge it as soon as the tests pass.
