How to extract YUV source files from MPEG2 TS file?

Question

I have a 1920x1080 mpeg2.ts file. I need to get raw YUV files for each frame. I tried ffmpeg but no luck. As a result, I have many small files. I expect each frame to be 1920x1080x1.5 = 3110400 bytes.

Answer 1

You can also use the -vframes option to get one yuv frame, as shown below:

 ffmpeg -i video.ts -pix_fmt yuv420p -vframes 1 foo-1.yuv 

Answer 2

When using an image as the format (-f image2), it assumes the mjpeg format, which is an image compression format. So yes, your solution is correct, you need to remove -f image2.
