pub fn renderer_codecs() -> (String, String)Expand description
What the renderer that will actually decode video on this platform can play.
Returns (video_codecs, audio_codecs) as Jellyfin-style comma lists.
This exists because the answer was previously derived in four places and
hardcoded in a fifth, each of them assuming the webview was decoding:
the device profile, the transcoding targets, the direct-play audio
narrowing, the client-side audio override, and get_video_stream_url’s
VideoCodec. On Android the decoder is ExoPlayer, so every one of those was
wrong there — the observed cost being an hevc source re-encoded to h264
because its audio was eac3, and dts forced to transcode though the device
decodes it.
One source, so the copies cannot disagree again.
