Error when reading a video.

[sotelo]

Describe the bug
I am able to use VPF to read/write videos but there's a particular video where I get the following error:

Codec not supported on this GPU
Decoder not initialized.Cuvid parser faced error.
Cuvid parser exception happened.

Here's the video:

The codec of the video is h264 and the size is 1080x720 so I don't understand why I get this error. Could you please help me figure this out?

Which GPU do you have? The video is h264 encoded by nvenc at 4:4:4. Is bit depth 10bit? Did you encode with the same GPU as you're now trying to decode?

Relevant code location throwing the error

VideoProcessingFramework/src/TC/src/NvDecoder.cpp

Lines 208 to 219 in 3ba39fb

	CUVIDDECODECAPS decodecaps;
	memset(&decodecaps, 0, sizeof(decodecaps));
	decodecaps.eCodecType = pVideoFormat->codec;
	decodecaps.eChromaFormat = pVideoFormat->chroma_format;
	decodecaps.nBitDepthMinus8 = pVideoFormat->bit_depth_luma_minus8;
	ThrowOnCudaError(m_api.cuvidGetDecoderCaps(&decodecaps), __LINE__);
	if (!decodecaps.bIsSupported) {
	throw runtime_error("Codec not supported on this GPU");
	}

Hello! Thank you for the fast response. I'm using a NVIDIA GeForce RTX 3090 GPU.

I used this code to preprocess the video:

def format_file(video_path, output_path):
    command = (
        f"ffmpeg -hide_banner -loglevel quiet -y"
        f" -i {video_path} -r 25 -vf scale=1080:720 -c:v h264_nvenc -acodec aac -ar 16000 {output_path}"
    )
    subprocess.call(command, shell=True, stdout=None)
