Extract yuv frames from yuv video

Question

What is the best way to extract individual yuv frames from a yuv video? Can we use ffmpeg?

I'm able to extract individual jpg frames but am struggling to extract individual yuv frames. I know that I can write my own script in python to extract this as the frames in yuv videos are just stacked against each other in raw format but wondering if there's a command line command I can just use for this.

Solution

Using ffmpeg,

ffmpeg -f rawvideo -framerate 25 -s 1280x720 -pixel_format yuv420p -i in.yuv -c copy -f segment -segment_time 0.01 frames%d.yuv

Replace the framerate, size and pixel format with the correct values, of course.

Thanks @mulvya! So the idea is to segment the video, and I should modify the segment_time such that only one frame is included in the segment? Will it be possible to precisely extract just one frame when fps is not integral (e.g: 24.58)? Should I first convert fps into 1 fps and then do this? Thanks!

As long as segment_time is less than 1/fps, each segment will be one frame.

Oh yes of course. Thanks @mulvya! Do you know what I should change if I want to use mp4 (hevc/h265 encoding) as input. Is the only way to first convert to yuv video and then apply the above

ffmpeg -i in.mp4 -f segment -segment_time 0.01 frames%d.yuv
