Bug Fixes

devcontainer

• Add -y flag to brew upgrade in postStartCommand

ffmpeg

• Add libavcodec 63 version guards for pix_fmts field move
• Pass original NvBufSurface fd through DRM_PRIME format_modifier
• Propagate hw_frames_ctx in VIC scale filter output
• Use original NvBufSurface fd for encoder DRM_PRIME input
• Propagate hw_frames_ctx on DRM_PRIME output frames
• Make VIC scale filter reinit-safe for FFmpeg 7.x
• Add VIC filter passthrough and use MMAP encoder for DRM_PRIME
• Use feature detection for FF_PROFILE compatibility guard

nvmpi

• Use GPU compute for VIC filter to avoid Tegra driver deadlock
• Use VIC compute mode instead of GPU for scale filter transforms
• Use internal buffer copy for encoder DMABUF input
• Guard decoder pool release callback against use-after-free

nvmpi, ffmpeg

• Use registered surface copy for VIC filter DRM_PRIME input
• Serialize NvBufSurfTransform to prevent Tegra driver deadlock

Features

ffmpeg

• Dlopen lazy-loading for libnvmpi — no link-time dependency
• Add DRM_PRIME output support to all nvmpi decoders
• Add DRM_PRIME input support to all nvmpi encoders
• Add hwcontext_nvmpi for -hwaccel nvmpi support
• Add DRM_PRIME to CUDA zero-copy transfer via EGL interop
• CUDA interop for hwcontext_nvmpi

nvmpi

• Add DMA-BUF fd passthrough API for zero-copy decode/encode
• VIC hardware scale filter

nvmpi, ffmpeg

• Add VIC hardware scale filter for zero-copy DRM_PRIME scaling

Testing

ffmpeg

• Add VIC scale filter hardware test suite
• Add diagnostic test case for VIC scale filter pipeline
