Summary of the bug:
When trying to use an nVidia GPU for decoding video, it fails with the
following output (a full trace attached):
[h264 @ 0x558d24633900] NVDEC capabilities:
[h264 @ 0x558d24633900] format supported: yes, max_mb_count: 65536
[h264 @ 0x558d24633900] min_width: 48, max_width: 4096
[h264 @ 0x558d24633900] min_height: 16, max_height: 4096
[h264 @ 0x558d24633900] Error creating a NVDEC decoder: 1
[h264 @ 0x558d24633900] Failed setup for format cuda: hwaccel
initialisation returned error.
[h264 @ 0x558d24633900] Format cuda not usable, retrying get_format()
without it.
The trace attached is for an AVC video, but the same occurs for HEVC.
The system has two GTX 1080 Tis (1b06 rev a1), and the driver version is
384.111. I have managed to run CUDA programs without problems.
How to reproduce:
{{{
% ffmpeg -loglevel trace -hwaccel cuvid -i small.mp4 small2.mp4
ffmpeg version 3.4.git-1
built on gcc 7 (Debian 7.2.0-19)
}}}
