Hello ,
When i tried to run with ffmpeg below command
ffmpeg -i /apache/data/data/mediarecordserver/50892/callee/ConnecTEB_50892_callee.webm -c:v h264_nvenc -profile high444p -pixel_format yuv444p -preset default output.mp4
get an error like this →
[h264_nvenc @ 0x2cc1380] Failed creating CUDA context for NVENC: 0x3e7
[h264_nvenc @ 0x2cc1380] No NVENC capable devices found
[h264_nvenc @ 0x2cc1380] cuCtxPushCurrent failed
Error initializing output stream 0:0 – Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
[aac @ 0x2ccb640] Qavg: 301.643
[aac @ 0x2ccb640] 2 frames left in the queue on closing
Conversion failed!
How can i get over this problem ?
