Ffmpeg frame extraction with Nvidia GPU acceleration throws "Output file #0 does not contain any stream"


I am trying to use nvidia gpu accelerated decoder api with ffmpeg, to extract all frames from a video file (.MTS) to a folder, but it looks like it's failing for some reason; I could not find an answer or similar issues.

Command used:

ffmpeg -vsync 0 -hwaccel cuvid -c:v mpeg2_cuvid -i raw_video.MTS -q:v 2 -f image2 output_folder/image_%05d.jpg

Traceback:

I am pretty sure -hwaccel cuvid -c:v mpeg2_cuvid is correct as the file type seems to be MPEG-2 in the file properties, but similar issues happen with the other cuvid decoders as well:

enter image description here

I have also tried to run without -c:v flag but then a cuda error is raised and it runs on the cpu:

[h264 @ 0x55949e6d7e00] decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed -> CUDA_ERROR_INVALID_VALUE: invalid argument [h264 @ 0x55949e6d7e00] Failed setup for format cuda: hwaccel initialisation returned error.

Any help will be much appreciated.

Solution

  • The video codec is actually h264. MPEG2-TS is a container/packaging format and need not contain only MPEG-2 video streams.

    When decoding a video using a hardware decoder such as cuvid, the decoded frames are in an hardware-specific data layout in hardware device memory. Before they can be transferred to system memory, they need to be converted to an acceptable layout.

    Add the filters hwdownload to copy the frames to system memory, and a format filter immediately afterwards to specify the downloaded format for hwdownload. nv12 is a variant of yuv420p for which a hW->SW conversion is available in ffmpeg.

    ffmpeg -hwaccel cuvid -c:v h264_cuvid -i raw_video.MTS -vf hwdownload,format=nv12 -vsync 0 -q:v 2 -f image2 output_folder/image_%05d.jpg
