Video decode about ffmpeg.wasm HOT 4 CLOSED

For a quick solution, you can use Worker.run with the solution here: https://stackoverflow.com/questions/27568254/how-to-extract-1-screenshot-for-a-video-with-ffmpeg-at-a-given-time

We will consider adding this api to Worker to make it more convenient.

Can you elaborate more about this requirement? Not sure about the meaning of frames by frames.

I think they want to extract the "real" frames of the video. This is (at least when I last tried it) really hard to do using web APIs (e.g. by drawing a video to a canvas and saving the frames), because you end up with the frames from the display frame rate rather than the video's frame rate.

I think this problem may actually be semi-solved by a new upcoming feature in browsers: HTMLVideoElement.requestAnimationFrame().

Hi @jeromewu Sorry for the late reply.

I meant the video frames, video frame extractor at a particular start and end time.
