I’m trying to record a time lapse using ffmpeg. My input settings are:
ffmpeg -y -f v4l2 -input_format yuyv422 -framerate 0.333
I have tried to create both x264 and x265 output in an mp4 file.
But when the recording starts, I get this message:
The driver changed the time per frame from 1000/333 to 1/5
This results in the frame rate being sped up 15 times what I asked for! 5fps is the actual frame rate the device is sending, but I thought I could get ffmpeg to basically record at a slower frame rate per this answer, so why isn’t it working?
For what it’s worth, I’m trying to record uncompressed (yuyv422) and compress it directly to the final output format directly for maximum quality, and I don’t want to insert any additional steps like “record at a higher frame rate and then sample it down later”.
