* fix: allow WAV direct play by aliasing pcm and wav codecs
WAV files were being transcoded to FLAC even when the browser declared
native WAV support. The backend normalizes ffprobe's pcm_s16le (and
similar PCM variants) to the internal codec name "pcm", while browsers
advertise WAV support as audioCodecs:["wav"] in their client profile.
The direct-play codec check compared these literally and rejected the
match with "audio codec not supported", forcing a needless FLAC
transcode.
Added {"pcm", "wav"} to codecAliasGroups so the matcher treats them
as equivalent. The container check runs first, so AIFF files (which also
normalize to codec "pcm" but use container "aiff") cannot
accidentally match a WAV direct-play profile.
* feat: include profile details in direct-play rejection reasons
The transcodeReason array returned by getTranscodeDecision previously
contained one generic string per failed DirectPlayProfile (e.g., five
copies of "container not supported"), making it hard to correlate a
reason with the profile that rejected the stream.
Each rejection reason now embeds the offending source value (in single
quotes) along with a compact representation of the full profile that
rejected it, rendered as [container/codec]. For example, clients with
two distinct ogg-container profiles (opus and vorbis) produced two
identical rejection strings; they now read "container 'wav' not
supported by profile [ogg/opus]" and "container 'wav' not supported
by profile [ogg/vorbis]", making each entry in the transcodeReason
array unique and self-describing.
A small describeProfile helper renders profiles as [container/codec]
(or [container] when no codec is constrained).
* refactor(stream): address code review — narrow pcm/wav match, tighten tests
Responds to reviewer feedback on the initial PR:
- Replace the symmetric pcm↔wav codec alias with a contextual
isPCMInWAVMatch check in checkDirectPlayProfile. The alias
unconditionally equated the two names in matchesCodec, which would
let AIFF sources (also normalized to codec "pcm") falsely satisfy
a codec-only ["wav"] direct-play profile that omitted containers.
The new check additionally requires src.Container == "wav" before
bridging the names, closing the false-positive path.
- Tighten the rejection-reason test assertions to verify the new
formatted output (source value + profile descriptor) instead of
just matching loose substrings like "container", preventing
unrelated rejections from satisfying the expectations.
- Add coverage for the WAV→wav-codec acceptance path and for the
AIFF-in-wav-codec-profile rejection path to pin down the contract
of isPCMInWAVMatch.
* refactor(codec): rename isPCMInWAVMatch to matchesPCMWAVBridge for clarity

* fix(server): capture ffmpeg stderr and warn on empty transcoded output
When ffmpeg fails during transcoding (e.g., missing codec like libopus),
the error was silently discarded because stderr was sent to io.Discard
and the HTTP response returned 200 OK with a 0-byte body.
- Capture ffmpeg stderr in a bounded buffer (4KB) and include it in the
error message when the process exits with a non-zero status code
- Log a warning when transcoded output is 0 bytes, guiding users to
check codec support and enable Trace logging for details
- Remove log level guard so transcoding errors are always logged, not
just at Debug level

* fix(server): return proper error responses for empty transcoded output
Instead of returning HTTP 200 with 0-byte body when transcoding fails,
return a Subsonic error response (for stream/download/getTranscodeStream)
or HTTP 500 (for public shared streams). This gives clients a clear
signal that the request failed rather than a misleading empty success.

* test(e2e): add tests for empty transcoded stream error responses
Add E2E tests verifying that stream and download endpoints return
Subsonic error responses when transcoding produces empty output.
Extend spyStreamer with SimulateEmptyStream and SimulateError fields
to support failure injection in tests.

* refactor(server): extract stream serving logic into Stream.Serve method
Extract the duplicated non-seekable stream serving logic (header setup,
estimateContentLength, HEAD draining, io.Copy with error/empty detection)
from server/subsonic/stream.go and server/public/handle_streams.go into a
single Stream.Serve method on core/stream. Both callers now delegate to it,
eliminating ~30 lines of near-identical code.
* fix(server): return 200 with empty body for stream/download on empty transcoded output
Don't return a Subsonic error response when transcoding produces empty
output on stream/download endpoints — just log the error and return 200
with an empty body. The getTranscodeStream and public share endpoints
still return HTTP 500 for empty output. Stream.Serve now returns
(int64, error) so callers can check the byte count.

* fix: use ADTS format for AAC transcoding to avoid silent output on ffmpeg 8.0+
The fragmented MP4 muxer (`-f ipod -movflags frag_keyframe+empty_moov`)
produces corrupt/silent audio when ffmpeg pipes to stdout, confirmed on
ffmpeg 8.0+. The moof atom offset values are zeroed out in pipe mode,
causing AAC decoder errors. Switch to `-f adts` (raw AAC framing) which
works reliably via pipe and is widely supported by clients including
UPnP/Sonos devices.
* fix: exclude AAC from transcode decision, as it is not working for Sonos.

When a client requests transcoding with an explicit format (e.g.,
format=opus) but no maxBitRate, buildLegacyClientInfo was adding a
direct play profile matching the source format. Since there was no
bitrate constraint to block it, MakeDecision would match the source
against the direct play profile and return the raw file instead of
transcoding. This fix only adds the direct play profile when no
explicit format was requested (bitrate-only downsampling) or when the
requested format matches the source format (allowing direct play when
no actual transcoding is needed).
* refactor: rename core/transcode directory to core/stream
* refactor: update all imports from core/transcode to core/stream
* refactor: rename exported symbols to fit core/stream package name
* refactor: simplify MediaStreamer interface to single NewStream method
Remove the two-method interface (NewStream + DoStream) in favor of a
single NewStream(ctx, mf, req) method. Callers are now responsible for
fetching the MediaFile before calling NewStream. This removes the
implicit DB lookup from the streamer, making it a pure streaming
concern.
* refactor: update all callers from DoStream to NewStream
* chore: update wire_gen.go and stale comment for core/stream rename
* refactor: update wire command to handle GO_BUILD_TAGS correctly
