Make the two codec tables answer for each other, and stop describeAudio printing a NUL
The FFprobe codec vocabulary is written out in at least four places and none of them had a test. Two had already drifted apart. `x264`, `hev1`, `x265` and `vp09` resolved in `CodecNames.videoFromName` and returned null from `AndroidDeviceCodecs.mimeForCodecName`, so the app identified the codec for the source card and for routing and then ran the device capability check blind on the same string; `mpeg4` ran the other way and rendered as a raw name. Nothing could notice, and the reason is structural: a `when` cannot be enumerated, so no test can ask one table what the other one knows. Both are maps now, for that reason alone, and `CodecVocabularyTest` walks the two key sets. A name added to -- or removed from -- one side alone fails the build. The one legitimate asymmetry is listed rather than implied: `mpeg4` is decodable input with no `VideoCodec` to name it, so `CodecNames` is right not to carry it. That list is itself checked, because otherwise it is an escape hatch -- any future divergence could be waved through by adding the name to it, and adding `x265` to it now fails. THIS CHANGES BEHAVIOUR for `x264`, `hev1`, `x265` and `vp09`. A null from `mimeForCodecName` means "unknown to us: assume the platform can handle it and let a failed export trigger the FFmpeg fallback", which is the right policy for a name nobody recognises and the wrong one for a name recognised one file over. A device without the matching decoder now sends those four to FFmpeg up front instead of spending a doomed hardware attempt to discover it. No input loses hardware it could have used: each alias resolves to the MIME its canonical spelling already resolved to, so a device that has the decoder still answers true. `ConversionRouterTest` still passes and that is not evidence either way -- every `canDecode` in it is a hand-written stub that never reaches this table. #74 is the same family one level down. `describeVideo` answered "Unrecognised" for `InputProbe.UNPARSEABLE` and `describeAudio` had no such arm, so an unparseable audio codec would have fallen through to `?: name` -- and the sentinel opens with a NUL, so the source-info card would have rendered a `Text` beginning with U+0000. The two now share one body, which is what stops the next arm being added to one side only. Two corrections to that ticket, taken from the file rather than from the ticket, since it warns about exactly this: - It quotes `audioFromName` as opening with `null, InputProbe.UNPARSEABLE -> null`. It did not; it opened with `null -> null` and the sentinel reached `else`. Naming the sentinel in the shared lookup therefore changes no answer and is documentation, not the fix. - It says `describeVideo`'s arm has no test of its own. It did -- `descriptions stay readable for unknown and missing codecs` asserts it -- so deleting the shared arm now reddens three tests across both sides, not one. Mutations run, each on the full 386-test suite: add "avc3" to CodecNames only -> CodecVocabularyTest red on two counts, CodecNamesTest green: 8 tests, 0 failures, which is the ticket's point about per-table arm tests delete the UNPARSEABLE arm -> CodecNamesTest red on three, one of them quoting the NUL back add "x265" to DECODE_ONLY_NAMES -> CodecVocabularyTest red on the escape hatch delete "vp09" from the MIME map -> CodecVocabularyTest red on three, which is the state this commit is fixing Audio is not cross-checked, and that is a gap rather than a decision: the device capability check is video-only, so this module has no second audio table to compare `AUDIO_ALIASES` against. `Media3Engine.audioMimeTypeFor` is the other half and belongs to #85. `MediaProbe.shortName` (#84) is the fourth table and is untouched here for the same reason. Closes #87. Closes #74. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Apply ktlintFormat
Tool output only, no hand edits, so this is safe to read with whitespace diffing off. It is its own commit for exactly that reason: a whole-repo reformat folded into the commit that configured the formatter would have made both unreviewable. What it did, mostly: trailing commas on wrapped argument lists, signatures collapsed onto one line where they fit inside 120 columns, import order, and four genuinely unused imports removed. Unit tests pass unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Let the user pick a container and codecs independently, and remux without re-encoding
OutputFormat was a closed enum of twelve (container, videoCodec, audioCodec) triples, defended on the grounds that a closed set was what made routing decidable. Two things it could not express: changing the container while copying the streams, and choosing codecs per track. OutputSpec replaces it as the vocabulary; OutputFormat stays as presets over it. Decidability moves to ContainerCapabilities, which is explicit and unit-tested rather than implicit in whichever combinations somebody enumerated. The matrix is indexed by (container, codec, trackType, mode), not one boolean. "Can MP4 carry AV1" and "can this app encode AV1" have different answers, and copy is where the difference shows: a single flag would refuse a legitimate remux or promise an encode neither engine can deliver. COPY is a codec value rather than a flag, so every exhaustive `when` in the codebase had to say what it does about copying. CopyPlanner resolves it before anything else reads the request, and inherits ConcatPlanner's rule that an unproven match is never a copy — a needless re-encode costs time, a wrong stream copy costs a file that will not play. Container now drives -f, the extension and the SAF MIME type, so Matroska without video is .mka and MP4 without video is .m4a without a preset for each. FLAC was declared as Container.MKV with a .flac extension, inert only while nothing read the container; it now has its own. Six containers added: MOV, MKV audio, MPEG-TS, AVI, FLV and WMV/ASF. Routing asks the plan, never the request. COPY belongs to none of the capability sets, so testing the request directly sends every remux to FFmpeg on the first check — and nothing notices, because -c copy produces a correct file, just on the CPU. The router also learns what Media3 can *carry* as opposed to encode: its MP4 muxer takes AAC, Opus, Vorbis and PCM but neither MP3 nor FLAC. MediaProbe now separates "no video track" from "could not parse" and reports the source container, which MediaExtractor cannot supply at all. FFprobe runs on every pick for that reason, not as a fallback. The Advanced picker shows the whole matrix and lets an impossible combination be selected on purpose, then explains it and offers alternatives. Convert is what blocks the job. ConversionWorker validates too, so a stale queued spec fails with the reason rather than being coerced into something else. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

Rename the project to LibreMediaConverter
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.
