Is it possible to create a raw YUV video from H264 encoded video using ffmpeg? I want to open the video with matlab and access Luma, Cb and Cr components frame by frame.

YUV is a class of pixel formats used in video applications, including VLC media player.
YUV is a color model typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, compared to a "direct" RGB-representation.
Here is the command to play a YUV video using ffplay . The parameters are pretty self-explanatory at this point. To control ffplay , you can use your spacebar to pause/play, f to toggle between full-screen and native display size, and the arrow keys to skip forward and back.
Yes you can, you just have to specific the pixel format. To get the whole list of the format:
ffmpeg -pix_fmts | grep -i pixel_format_name For example if you want to save the 1st video track of an mp4 file as a yuv420p (p means planar) file:
ffmpeg -i video.mp4 -c:v rawvideo -pix_fmt yuv420p out.yuv If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
