Converting directory full of h264 to images

  • 772

first time here. Please be gentle. let me know what I missed out on and I will correct it.

my question is similar to this. So, I am hoping to get an answer for my specific query too.

How can I convert .264 file to .mp4

I have an entire directory with frames in .h264 format. These are generated from WebRTC for a single video.

I am able to convert the very first frame to image. However, when I am trying it for the subsequent frames, I am getting an error with ffmpeg. I am assuming there might be some dependency on the prior frames because of which I am getting this error.

How can I convert all the frames in that directory to images (jpeg or png)

video conversion ffmpeg mp4 h264

  1. Typical H.264 frames are interdependent, so most frames can't be decoded individually.

    Use cat to combine them all and pipe to ffmpeg:

    cat *.h264 | ffmpeg -i - frame-%04d.png

  2. You could try to use handbrake.

    $ HandBrakeCLI -Z Universal -i myinputfile -o myoutputfile

    I found it here. Maybe it'll help.

    And pleases also provide the error message, so we can help you more effectively.
