make fate HWACCEL=auto fails wih CUDA_ERROR_INVALID_IMAGE

[Slava Andrejev]

I tried to run make fate HWACCEL=auto. It failed on ljpeg test.

Here is the command line that the test is using:

% ffmpeg -nostdin -nostats -cpuflags all -flags +bitexact -idct simple -sws_flags +accurate_rnd+bitexact -fflags +bitexact -threads 1 -hwaccel auto -threads 1 -

I have information that lossless JPEG is not supported by the GPU. How to make this regression test run in software even if HWACCEL is specified?

[Carl Eugen Hoyos]

No GPU supports lossless jpeg.

This ​https://en.wikipedia.org/wiki/Lossless_JPEG is I think not supported by Nvidia... You can ask them ​https://devtalk.nvidia.com/default/topic/379117/cuda-programming-and-performance/lossless-jpeg-fast-decompression-on-cuda/post/2704877/#2704877

Anyway ffmeg still does not do Cuda Flac! And that one much more better vs simple flac! But they do not care...

[Slava Andrejev]

I asked, it's not supported. The question is not about the support, the question is how to make make fate run giving the circumstances.
