Fix PCM audio transcoding to wav returning HTTP 500 and headerless output

2026-08-04T17:52:29Z

`GetProgressiveAudioFullCommandLine` forced the raw PCM muxer and a bogus sample rate whenever the audio encoder was `pcm_*`, regardless of the container the client asked for. Two separate failures came out of it: - `-ar ` + `state.BaseRequest.AudioBitRate` used a *bitrate* as a *sample rate*, and `AudioBitRate` is optional. When it is absent the argument degrades to a bare `-ar`, ffmpeg aborts with `Expected number for ar but found: -ar` / `Error opening output files: Invalid argument` (exit 234) and the request fails with HTTP 500. Every `GET /Audio/{id}/stream.wav` that does not carry an explicit `AudioBitRate` hits this. The sample rate was already being set correctly a few lines below from `OutputAudioSampleRate`, so the line is dropped rather than repaired. - `-f s16le` overrode the muxer even for a real container. A request that did supply a bitrate (`/Audio/{id}/universal` passes `MaxStreamingBitrate`) survived the first bug but produced raw headerless samples served under an `audio/wav` content type, so clients saw a body with no RIFF header. The raw muxer is now only forced when the requested container is actually raw PCM, which keeps the I2S/MCU route from #10321 working. Also drop the `containerInternal = ".pcm"` assignment in `StreamingHelpers.GetStreamingState`: it is written after `state.OutputContainer` has already been read from the same variable and is never read again, so it has no effect and only obscures where the output container comes from. Verified against ffmpeg 8.1.2 with a 96 kHz FLAC source: before, the wav command line exits 234; after, it produces a valid `RIFF/WAVE` 48 kHz stereo `pcm_s16le` file, while the raw `.pcm` route still yields exactly 2 s x 48000 x 2ch x 2 B = 384000 bytes of headerless samples.

Fix Live TV returning unreachable "server-local" streaming URLs to clients.

Append base URL if the published server URL override omits it. Fleshed out unit tests to cover that and https->http reverse proxy scenario(s).

Fix NullReferenceException in GetStreamingState for closed live streams

2026-06-30T05:13:51Z

When a client polls the HLS playlist (e.g. live.m3u8) after a live stream has been disposed because its consumer count dropped to zero, GetLiveStreamWithDirectStreamProvider returns a null MediaSource. The live branch of GetStreamingState then dereferenced it unconditionally, throwing a NullReferenceException and returning HTTP 500 for every poll until the client re-opens the stream. Guard against the null MediaSource and throw ResourceNotFoundException so the request returns 404 instead of crashing. Fixes #17009 Co-Authored-By: Claude Opus 4.8 (1M context)

Keep the queried item's media source as the playback default
