Hi Carl,
Just now gone through the documentation, and got know -r used for FPS. So I had
made changes and executed the command as follows,
but I got the same following errors while playing using ffplay. Kindly please
help me in this regard.
Command:
ffmpeg -f alsa -thread_queue_size 1024 -i
Hi Carl,
Thanks for the reply. -f 25 for encoding the video in 25 FPS (because 1000
milliseconds / 40 milliseconds = 25 frames) and tell FFmpeg to use every frame
as a key frame (-g 1).
Thanks & Regards,

Hi,
I’m trying to record audio and video from webcam with ffmpeg using below
command, but I’m unable to play all generated files using ffplay.
Command:
ffmpeg -f alsa -thread_queue_size 1024 -i hw:0 -f video4linux2 -i /dev/video0
-c:a aac -t 0:10 -segment_time 00:00.040 -f segment
