I am capturing the screen using DXGI and obtaining a ID3D11Texture2D if I download that to CPU and use av_hwframe_transfer_data, the encoder works fine.
But I am trying to remove that step of downloading the texture to CPU and trying to pass it directly, trying to send the GPU memory pointe directly into the encoder. But when I try to do that I am getting the following error:
[h264_nvenc @ 00000191233e1bc0] Error registering an input resource: invalid call (9): [h264_nvenc @ 00000191233e1bc0] Could not register an input HW frame Error sending a frame to the encoder: Unknown error occurred
I am basically doing same that this user of stackoverflow → c++ - FFMPEG using AV_PIX_FMT_D3D11 gives “Error registering the input resource” from NVENC - Stack Overflow with similar results…
And I am using latest version of ffmpeg at the minute, v6.0.
Any tips on how to proceed with this ?
