* craft-media: MXF identification on every writer entry point, and a total metadata budget write_opatom_pcm_as takes the company, product and version that WriterConfig already has, and the product UID is derived from the product name, so an app that names itself writes the bytes it wrote before the move. Everything read while opening shares a 256 MiB budget: a file made of metadata sets, each under the 64 MiB value limit, is refused instead of read whole. * craft-media-testkit: hostile-input hammer Truncations, bit flips, extreme-value overwrites in both byte orders and deletions of a valid input, each run under catch_unwind with a time budget. CRAFT_MEDIA_HOSTILE_MULT multiplies the iterations for soak runs. Ported from storytold/filmcraft#1794 (filmcraft-testkit's hostile module). * craft-media: MXF hostile-input hammer The hammer over three synthetic OP1a files and over an index segment, a primer pack and a metadata set parsed directly, and the regression test for sync_before on a track without samples (the fix is already in the module). Ported from storytold/filmcraft#1794 (crates/mxf/src/tests/hostile.rs). * craft-media: MXF picture descriptors give the H.273 code points of their colour labels PictureInfo::color_codes maps the colour primaries, transfer characteristic and coding equations labels the writer uses (Rec. 709, BT.2020, PQ, HLG) to their code points, whatever the label's registry version byte. Ported from storytold/filmcraft#4100 (the crates/mxf part). * craft-media: MXF writer describes interlaced pictures, and the reader gives the field dominance PictureDesc::interlaced writes the SeparateFields frame layout with a field's stored and sampled height, the 1080i video line map and the field dominance (bottom_field_first: 2). PictureInfo::field_dominance reads it back. Ported from storytold/filmcraft#4497 (the crates/mxf part). * craft-media: AVI hostile-input hammer The hammer over the four synthetic layouts (idx1 relative and absolute, rec lists, no index, OpenDML), opened with and without the OpenDML index. Ported from storytold/filmcraft#1794 (crates/avi/src/tests/hostile.rs). * craft-media: AVI says how an H.264 or HEVC stream frames its NAL units The bytes after a video stream's format header are nothing, Annex B parameter sets (ffmpeg with global headers) or an avcC / hvcC record (a stream copied from MP4, with length-prefixed chunks). Stream::nal_framing tells them apart and gives the length-prefix size, so a caller hands the decoder the header's parameter sets and turns length prefixes into start codes. codec_params said the bytes were never a record. Ported from storytold/filmcraft#2303 (the container part of NalSetup in filmcraft-codecs; the decoder wiring stays in the app). * craft-media: MPEG-TS / PS hostile-input hammer The hammer over transport streams (188- and 192-byte packets, six stream types), program streams (MPEG-2 and MPEG-1 packs, private stream 1) and the frame-header helpers for every codec. Fewer rounds than in FilmCraft, where tests build with optimisation. Ported from storytold/filmcraft#1794 (crates/mpegts/src/tests/hostile.rs). --------- Co-authored-by: Logan Jennings <loganwjennings@gmail.com> Co-authored-by: JonRC <jonarc06@gmail.com> Co-authored-by: Michael de Meyer <249562202+oblivion8282-1337@users.noreply.github.com> Co-authored-by: tylerjenningsw <tylerjennings2@outlook.com>
