video - How to use ffmpeg with h.265 (or h.264) coded? -

normally start recording camera image command:

ffmpeg -y -f vfwcap -r 25 -i 0 out.mp4

but i'm not sure coded use in here (i'm beginning adventure ffmpeg), found on this webpage command:

ffmpeg -i input -c:a copy -x265-params crf=25 out.mov

but when run - following error: input: no such file or directory"

i changed input word above 0, command is

ffmpeg -i 0 -c:a copy -x265-params crf=25 out.mov, error stays similar (0: no such file or directory). how can grab camera image , save file while using h.265?

you'll have better understanding of how ffmpeg works , each parameter means. documentation is here, have fun.

in case:

          |------ input ------||----- output ------|  ffmpeg -y -f vfwcap -r 25 -i 0 -c:v libx265 out.mp4 

your input vfwcap device id 0 captures @ rate of 25 fps. output mp4 file containing video stream encoded libx265.

if use -i 0 wihtout format assumes you're trying input file, , can't find file.

for work need have x265 encoder installed on system , ffmpeg compiled with libx265 support.
