commit a02dfb1262564528a011f0d3e2a97cdce33bd90a Author: Diego de Souza <[email protected]> AuthorDate: Wed Jun 24 00:30:45 2026 +0200 Commit: Timo Rothenpieler <[email protected]> CommitDate: Tue Jun 23 23:58:45 2026 +0000 avcodec/cuviddec: map new NVDEC 4:2:0/4:2:2/4:4:4 output formats The switch to the new NVDEC pixel formats made cuvid_derive_output_format() and the format probe select AV_PIX_FMT_P012 for 12-bit 4:2:0, AV_PIX_FMT_P210/P212 for 10/12-bit 4:2:2 and AV_PIX_FMT_YUV444P10MSB/ YUV444P12MSB for 10/12-bit 4:4:4, but cuvid_handle_video_sequence() still only mapped the older formats to a CUVID surface format. Decoding such streams therefore failed with "Unsupported output format" (AVERROR(EINVAL)); because every packet then errored without producing a frame, the failure could also manifest as a hang rather than a clean error exit. The system-memory copy path in cuvid_output_frame() rejected the same formats with AVERROR_BUG. Map P012 to cudaVideoSurfaceFormat_P016 (mirroring P010), P210/P212 to cudaVideoSurfaceFormat_P216 (mirroring P216) and YUV444P10MSB/YUV444P12MSB to cudaVideoSurfaceFormat_YUV444_16Bit (mirroring YUV444P16); the hardware surface is physically 16-bit and the pixel format only records the number of valid bits. Add the same formats to the system-memory copy path, whose per-plane geometry is already derived generically from the pixel descriptor.
