from_coding_type maps 0x20 (MVC dependent view) to Codec::H264, so the existing
PAT/PMT scan surfaces the SSIF right-eye substream as a second video stream on
its own PID instead of dropping it as Unknown. No new parser: the dependent eye
rides the same demux path as any other TS video stream. Removes the throwaway
3D-structure probes (findings captured in prior commit messages).
Empirical (300, clip 00042): base .m2ts (1567 extents, 25.85 GB) is entirely
inside the SSIF LBA span; dependent = SSIF − base = 1567 ranges, 9.59 GB
(exact vs 35.43−25.85). 200/200 sampled dependent-view units decrypt under the
base UK. => de-interleave needs no SSIF parsing (complement of the base extents
we already resolve), and the dependent eye needs no extra key.
Dev tool for the 3D build: uses the library UDF reader (7z cannot parse these
ISOs) to dump base .m2ts vs SSIF sizes and the MPLS ExtensionData entries
(STN_table_SS + SS sub-path). Not product code.
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>.
