- timeformat node: localtime_s/gmtime_s (reversed args, 64-bit time_t)
on Windows — MinGW has no localtime_r/gmtime_r
- the multithread suite test passed non-NUL-terminated property names
(str::as_ptr) to the C property suite — UB that resolved to garbage
lookups on the CI runner
- libsnappy off on the MinGW FFmpeg build (only feeds the hap encoder;
its pkg-config entry does not reach the static link)
- FFmpeg for Windows no longer enables libopenh264 (redundant with the
native h264 decoder + x264 encoder; its MinGW packaging does not
satisfy the static link — Wels* undefined references)
- suites_test's question-type call passed a 3-placeholder format with
one variadic arg — UB that vsnprintf turns into a SIGSEGV on glibc
(masked on macOS); use a placeholder-free format
FFmpeg 8 removed the standalone hardware decoders (h264_videotoolbox/
vaapi/nvdec/d3d11va no longer exist in its configure) — hardware decode
now only exists as a hwaccel attached to the software decoder. The new
oakcodec::hwdecode module therefore opens the regular decoder with the
platform's hardware device context attached (VideoToolbox on macOS,
VA-API then NVDEC on Linux, D3D11VA then NVDEC on Windows): FFmpeg
engages the matching hwaccel, decodes into hardware surfaces, and we
transfer them to system memory (NV12/P010) ahead of swscale.
- HardwareDecoding config switch, default ON by mandate; a checkbox in
Preferences > Rendering (EN/ZH); device creation failure skips to the
next candidate and finally to software; a decode-time failure on a
hardware session reopens it as software and retries once.
- hw_decoder_name() observability hook plus a HW_TRANSFERS counter so
tests can prove the hwaccel really engaged (not silently software).
- Verification: demo.mp4 H.264 decodes through VideoToolbox with a
transferred hardware surface, and the pixels match the software
decode within 0.05; switch off forces software.
- build-ffmpeg.sh also enables nvdec when ffnvcodec headers exist.
- screenshot example inits i18n and captures both zh-CN and en-US
(docs/screenshot-window{,-en}.png)
- dock tabs size to content (no more 64px truncation); viewer/panel
titles follow the design (素材查看器·name etc.)
- mock project carries V1/V2 video + A1/A2 audio clips rendered as
rounded green bars; timeline clip geometry/rounded corners match the
design; status bar visible with full content; audio meter strip
docked at the program viewer's right edge; project explorer rows
have icons
- tests/waveform_e2e.rs: waveform cache extracts real peaks and hits
cache on re-query (P4 acceptance)
