Architecture:
- One stream per format, bidirectional PES (read/write on same type)
- IsoStream merged into DiscStream (one type, any SectorReader)
- Disc::copy() for disc→ISO raw sector dump
- IOStream trait deleted, all byte-level Read/Write removed
- ContentReader/OpenDisc/open_title/open_input/open_output deleted
- CountingStream wrapper for progress tracking
Error codes:
- All io::Error English strings replaced with Error enum variants
- From<Error> for io::Error conversion
- Unused variants removed, new stream/mux variants added
Deleted: mkvout.rs, pesout.rs, isowriter.rs, mkv-muxer-plan.md
Updated: all docs, README stream table, CHANGELOG
238 tests, 0 clippy warnings.
Streams are streams — they take impl Read, not Read+Seek or File.
- MkvStream::open takes impl Read (was Read+Seek)
- EBML element skipping uses skip_bytes() instead of seek(Current)
- Byte position tracking uses remaining-bytes counter, not stream_position()
- Removed file_size from open (progress is CLI concern)
- M2tsStream::open takes impl Read (was Read+Seek)
- Buffers first 1MB for FMKV header / PMT scan
- Uses chain reader (buffered head + rest) for sequential reading
- Duration unknown without seeking (0.0) — CLI can set from metadata
- Removed ReadSeek trait (no longer needed)
- WriteSeek kept (MKV muxer container format requires seeking internally)
- Remove unused pes_buf field from M2tsStream and unused TS_PACKET/BD_TS_PACKET constants
- Replace match-with-single-pattern with if let (3 instances in drive/mod.rs)
- Replace match-can-be-? with ? operator for scsi::open call
- Add type aliases PesSetup and MkvHeaderResult to reduce type complexity
- Collapse identical if/else branches in tsmux.rs build_pes_header
- Use RangeInclusive::contains instead of manual range checks
- Make WriteSeek trait pub (was pub(crate) but leaked through pub fn)
- Remove empty line after doc comment in disc.rs
- Fix doc list item indentation in scsi/linux.rs (12 instances)
- Unified Stream trait: read() and write() on one type
- PesFrame serialize/deserialize for wire format
- TsDemuxReader: shared BD-TS demux for any Read source
- MkvStream: PES read from MKV (EBML → PesFrame)
- M2tsStream: PES read via TsDemuxReader
- Network/Stdio output: PES serialization directly (no BD-TS wrap)
- Network/Stdio input: deferred (needs PES deserialization protocol)
- TsMuxer for M2TS output from PES frames
- input() and output() functions return Box<dyn Stream>
Stream trait: read() returns PesFrame, write() accepts PesFrame.
A stream is a stream — you read from it or write to it.
No separate Input/Output traits.
API: libfreemkv::input(url) and libfreemkv::output(url, title, codecs)
Returns Box<dyn Stream>.
- TsMuxer: PES frames → BD-TS packets (new, reverse of TsDemuxer)
- M2tsOutputStream: PES → TsMuxer → file
- NetworkOutputStream: PES → TsMuxer → TCP
- StdioOutputStream: PES frames → stdout
- NullOutputStream: discard
- MkvOutputStream: PES → MKV mux
- All outputs via open_pes_output()
- All inputs via open_pes_input() (ISO, disc)
- No byte-level fallback — everything is PES
- IOStream::keys() default returns DecryptKeys::None
- IsoStream and DiscStream override with real AACS/CSS keys
- Pipeline calls input.keys() instead of separate scan_keys()
- Streams are self-contained: read bytes + provide keys
