Hello.
I'm trying to decode and encode video on nvidia GTX960 card, and I've
stuck with a strange problem
If i'm specifying 720p resolution with -s 720x540 parameter - everything works.
But if i'm trying to specify any other resolution, i'm getting such error:
[h264_nvenc @ 0x27ecae0] InitializeEncoder failed: invalid param (8)
It doesn't matter on kind of input of output.
Here is working command:
ffmpeg -vcodec h264_cuvid -i
'udp://@232.0.5.133:1234?fifo_size=1048576&buffer_size=1048576&overrun_nonfatal=0'

Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height
After small research we've found that we're getting that error from
libnvidia-encode.so
Did anyone got same troubles, or may be solved such issue, or just
have any ideas?
