The in-app FFmpeg container demuxer classified every DTS variant as
plain DTS (profile-blind MIME mapping at the demux boundary), so
DTS-HD MA lost its lossless identity downstream, and it ignored
container display-aspect-ratio overrides. media3's extractors get both
right.
Delete the FFmpeg demuxer (JNI, extractor, and its setting); ExoPlayer
direct play demuxes with media3's DefaultExtractorsFactory again, and
mpv - the Android default - reads container display dimensions itself.

Direct play on Android kept accumulating container patches: AVI with
XviD packed-bitstream timestamps and missing VOL csd played broken,
ASF/WMV and MPEG-PS/VOB had no media3 extractor at all, and MKV needed
a custom extractor stack for zlib-compressed subtitles, LOAS/LATM
audio, cueless seeking, and font attachments.
Demux progressive containers with libavformat behind media3's
extractor API. An AVIO bridge serves libavformat from the
ExtractorInput: every position divergence defers into a RESULT_SEEK
round trip, header reads replay from a block cache while
avformat_open_input restarts, and avformat_seek_file executes seeks
with bounded loader round trips. Packets feed media3's TrackOutputs,
so decoders, passthrough carriers, Dolby Vision RPU/EL conversion
(dvh1 codecs string surfaced from DOVI side data), and the subtitle
pipeline are untouched: embedded fonts feed AssHandler over JNI, ASS
reaches libass as per-sample dialogue, SRT/VTT render as cues, VobSub
maps through media3's VobsubParser, and LOAS/LATM AAC unwraps via
LatmTrackOutput.
Under the default Auto preference FFmpeg demuxes AVI, ASF/WMV,
MPEG-PS, and Matroska/WebM and sits behind media3's list as an
any-container fallback; MP4/TS keep media3's extractors. A playback
setting exposes auto / FFmpeg first / media3 only, and the JNI
load-failure path falls back to stock media3. The custom Matroska
extractor stack and its reflection keeps are retired.
Verified on Pixel 7 (API 36), Box R 4K Plus TV (API 34), and SHIELD
TV (API 30): instrumentation playback suites, the minified R8
reachability gate, and an on-device container matrix with forward and
backward seek landings plus visual subtitle checks.

MKV files whose Tracks element follows media clusters could direct-play with audio but no video. Upgrade Media3 to 1.11.0 and cover the extractor regression.
