video/out/hwdec_cuda: use mp_msg for ffnvcodec logging - #18224
Merged
Conversation
ffnvcodec falls back to fprintf(stderr) unless FFNV_LOG_FUNC and FFNV_DEBUG_LOG_FUNC are defined by the user (https://github.com/FFmpeg/nv-codec-headers/blob/master/include/ffnvcodec/dynlink_loader.h#L80-L84). Define these callbacks so CUDA loader messages go through mpv's normal logging instead.
