FFmpeg live editing
17 octobre 2016, par NikxDaI am trying to create a video editing tool in HTML/CSS and PHP. For the video editing, I am using ffmpeg. Now, the file upload and the general editing works pretty well, but I have a problem. I would like to preview the final result inside an HTML video-tag. Thus, wenn I upload 4 clips and then select seconds 5 to 10 to be cut out, I’d like to immediately view the result so I can decide whether I want to keep it or not. Does FFmpeg support something like this ? If not, what would be the best solution ?
