hi, sorry for my bad english,
i read in internet, you can use GPU to help FFMPEG to run faster,
i have this intel HD graphic 4600, and nvidia geforce gtx 750 ti,
can i use it for FFMPEG?
if it can, can it set priority(like priority in task manager) to low or background?,
(i dont want my display lag when browsing)
thanks for reading

Specify h264_nvenc, hevc_nvenc, h264_qsv, or hevc_qsv as the encoder.
You can always use Windows' Start command to start programs at low priority.
Code:Start /b /low "Window Name" ffmpeg.exe...

Add to the command line after the source input:
Code:-c:v h264_nvenc
-
something like this
Code:"c:\ffmpeg.exe" -i "%~1" -c:v h264_nvenc -f segment "%~dp1output\%~n1.%%03d.mp4"
Code:[h264_nvenc @ 000002935ebf6480] Driver does not support the required nvenc API version. Required: 9.0 Found: 8.1 [h264_nvenc @ 000002935ebf6480] The minimum required Nvidia driver for nvenc is 418.81 or newer 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
thanks for the reply -

You might have to force the GOP size to match the desired segment time. For example, with a 25 fps video set the GOP size to 50 to match the 2 second segment size:
Code:-g 50

i will try it later. currently, the batch is processing 500mb of a video file, i don't know when it done,
meanwhile i looking for alternative way, making a list without -c:v h264_nvenc(or hevc_nvenc, h264_qsv, hevc_qsv),
and split the result using -c:v h264_nvenc, and i did not make any progress -
-
adding '-strict_gop 1' might help
users currently on my ignore list: deadrats, Stears555 -
thanks for the reply, i added the '-strict_gop 1', the result is like this
Code:"c:\ffmpeg.exe" -i "%~1" -c:v h264_nvenc -g 50 -strict_gop 1 -f segment "%~dp1output\%~n1.%%03d.mp4"
i still prefer using " -c:v h264_nvenc",
i know it very slow (almost 5x slower), but it precise,
thanks for your concern
