0.108.2: Dragon Ball GT's picture, built on the installed 0.108.1

Paul's report (4 November 2026, 21:58): Dragon Ball GT on Vortex "won't play on this device".

What the box showed:

• S1 E4 (item 228430) failed with noVideoDecoder=video/x-unknown.
• A 3-minute test of S1 E5 (228431) played sound and English subtitles with no video track (video=none).
• Emby reports every GT episode as H.264 640x480 in MKV with Vorbis audio. The library has only one copy, 64 episodes.
• The cause: the files carry their H.264 in the old Video for Windows wrapper (Matroska CodecID V_MS/VFW/FOURCC). Media3's Matroska reader recognises that wrapper only for DivX/Xvid, H.263 and VC-1, and labels anything else video/x-unknown.
• Paul doesn't own the Emby server, so remuxing the files there isn't an option. He asked for the fix in the app.

The fix:

• tv/orbit/classic/mkv/ is a copy of Media3 1.8.0's Matroska reader (Apache 2.0). It's unchanged apart from its package and one addition: parseFourCcPrivate also maps H.264 FourCCs (H264, X264, AVC1, DAVC, VSSH, either case) to video/avc. The stream is passed as it is, with its parameter sets in band, which the decoder reads.
• OrbitExtractorsFactory is Media3's DefaultExtractorsFactory with only the Matroska reader swapped. The programme, picture and ident players use it.
• Every other format and subtitle path is Media3's own.
• It's built on 0.108.1, the version on the box, so Advent and The Naughty List aren't in it. The same change is on main for later releases.

Checks

• 482 unit tests run, 0 failures. OrbitMatroskaTest adds 3: the H.264 FourCCs map, other FourCCs stay Media3's, and only the Matroska reader is swapped. Lint shows the same warnings as before and no errors.
• Not provable off the box: that GT now shows its picture. After the install, a 3-minute test of S1 E5 must show video=video/avc with a first frame.
• Episode 4: item 228430 stays on the failed list from 21:56. It can be cleared, so it's booked again, once the picture is confirmed.
