When i try decoding a sample using -hwaccel cuvid I get
[h264 @ 000001ab70730020] decoder->cvdl->cuvidCreateDecoder(&decoder->decoder,
params) failed -> CUDA_ERROR_INVALID_VALUE: invalid argument
[h264 @ 000001ab70730020] Failed setup for format cuda: hwaccel initialisation
returned error
That same sample works just fine if i instead use -hwaccel nvdec. And seeing
this
hwaccel is merely a ffmpeg.c specific implementation using AVHWFramesContext,
much
like the libavcodec hwaccel, i figured it was best to just remove it and map
cuvid
to nvdec in order to not break existing cli scripts.
The same can probably be done with the VideoToolbox one, but not the QSV as
there's
no such hwaccel in libavcodec (One should probably be written).
It should be working fine still, but there's really no reason to keep it.
