I just can't seem to get FFMPEG to play nice with hardware acceleration.
After the input file is read the following errors kick-back:
[h264 @ 000002366512e8c0] Video width 5120 not within range from 48 to 4096
[h264 @ 000002366512e8c0] Using more than 32 (40) decode surfaces might
cause nvdec to fail.
[h264 @ 000002366512e8c0] Try lowering the amount of threads. Using 16
right now.
[h264 @ 000002366512e8c0] Failed setup for format cuda: hwaccel
initialisation returned error.
And the encoding continues & completes.
The first error I think is because we are feeding it a video that is 5120px
wide.
The last error is the one that is persistent.
I've been staring at this one for too long and need another set of eyes.
I've tried probably 6 different formulas for compile/config ffmpeg to no
avail.
Here is my last try at this.
