Greetings, With the recent FFmpeg 5.1 supporting AV1 using VDPAU, should decoding AV1 occur on the GPU automatically (NVIDIA 3000 series), similarly to decoding VP9?
ffmpeg -y -hwaccel vdpau -i input_av1.mp4 output.ts # decodes on the CPU ffmpeg -y -hwaccel vdpau -i input_vp9.webm output.ts # decodes on the GPU Are the following incorrect usage? Both segfaults. ffmpeg -y -hwaccel vdpau -c:v av1_cuvid -i input_av1.mp4 output.ts # segfaults ffmpeg -y -hwaccel vdpau -c:v vp9_cuvid -i input_vp9.webm output.ts # segfaults Thanks, Mario On Wed, Jul 13, 2022 at 9:44 AM Mario Roy <[email protected]> wrote: > Hi, > > What are the recommended arguments for folks using NVIDIA 3000 series > graphics and decoding AV1 media?
