Media3Engine never called setMuxerFactory or setAudioMimeType, and built a bare
EditedMediaItem, so it always produced MP4 with an H.265 video track. The router
meanwhile sends it WebM, Ogg, WAV and AAC-ADTS jobs, plus audio-only M4A, Opus
and WAV — and ConversionWorker.media3MimeType() mapped VideoCodec.NONE through
its else branch to VIDEO_H265.
The visible result: "extract audio to M4A" transcoded the video to HEVC and
named the file .m4a. Nothing failed, and nothing caught it, because
Media3EngineTest had no audio-only case at all.
media3-muxer already ships WebmMuxer, OggMuxer, WavMuxer and AacMuxer; only the
MP4 ones come pre-wrapped as a Muxer.Factory. Media3Muxers supplies the rest.
Their reported sample MIME types are read from each muxer's own support check
rather than assumed, because Transformer uses those lists to decide whether a
track needs re-encoding.
HardwareTranscoder.transcode now takes the OutputFormat instead of a video MIME
string, which is what gives the container, the audio codec and "this output has
no video" somewhere to travel.
MEDIA3_CONTAINERS stops being private so a test can assert it agrees with the
factories. Those two drifted once already: the router's set was right the whole
time the engine was ignoring it.

Done now rather than later: the application ID is permanent once published --
Play treats a change as an entirely different app -- so this is the last
cheap moment to choose it.
applicationId / namespace dev.jasonmross.mediaconverter -> org.libremediaconverter
source tree java/dev/jasonmross/mediaconverter -> java/org/libremediaconverter
gradle project AndroidMediaConverter -> LibreMediaConverter
theme Theme.MediaConverter -> Theme.LibreMediaConverter
compose theme MediaConverterTheme -> LibreMediaConverterTheme
display name "Media Converter" -> "LibreMediaConverter"
org.* rather than dev.jasonmross.* because "Libre" signals a project rather
than a personal app, and a project-owned namespace lets maintainership move
later without the identifier contradicting reality.
The source trees moved with git mv so history follows the files instead of
showing 42 deletions beside 42 additions.
Verified after the rename: 66 unit tests, and 40 instrumented tests on an
API 36 emulator, 0 failures. The built APK reports org.libremediaconverter,
and no stale jasonmross, AndroidMediaConverter or MediaConverterTheme
identifiers remain anywhere in the tree.
