  • About youtube-dl

    30 octobre 2017, par 王延康

    As you all know, youtube-dl can download videos from youtube.com. Usually we use the directive e.g. youtube-dl -f 266+140 www.youtube.com/xxxxxx. Then youtube-dl will download the 266(only video) and 140(only audio) individually and then merge them with a wink.

    However, recently when I download a 4K HD video, the quality of the analyised audio only have 128kps. But I have the same audio at 320kps. I’ve tried only download the video without audio and use the ffmpeg to merge them. But the speed was so slow far less than the normal download ways.(266+140) So here comes the question, how can I use the youtube-dl and the ffmpeg to merge my video and 320kps audio quickly just like youtube-dl did ?

  • How to merge video and camera recording together in browser (Chrome especially) ?

    5 juillet 2021, par lzl124631x

    Goal

    


    I want to record/generate a video in browser (Chrome especially) with a custom video (e.g. .mp4, .webm) and camera recording side-by-side.

    


    --------------------------------------------------
|                        |                       |
|  Some Custom Video     |       My Camera       |
|                        |                       |
--------------------------------------------------


    


    What is working

    


    I can use MediaRecorder to record my camera, and play the recording side-by-side with my video, and download the recorded video as a webm.

    


    Challenge

    


    I'm facing difficulty merging the video and camera recording into a single video file side-by-side.

    


    My investigation

    


    MultiStreamMixer

    


    I first looked into MultiStreamMixer and built a demo with it (See codepen).

    


    enter image description here

    


    The issue with it is that it stretches the video content to fit them in the same size. I can specify different width/height for those two streams but it doesn't work as expected. My camera got cropped.

    Custom Mixer

    


    I took a look at the source code of MultiStreamMixer and found the issue was because of its simple layout logic. So I took its source code as a reference and build my custom mixer. See codepen.

    


    The way it works :

    


      

    • We first render the streams one by one to an offscreen canvas.

      • 


    • Capture the stream from the canvas as the output video stream

      • 


    • Audio stream is generated separately using AudioContext, createMediaStreamSource, createMediaStreamDestination etc.

      • 


    • Merge the audio and video streams and output as a single stream.

      • 


    • Use MediaRecorder to record the mixed stream.

      • 


    


    It adds black margins to video/camera and won't stretch the videos.

    However, I found the recording is very blurry if you wave your hand in front of your camera while recording.

    Initially I thought it was because I didn't set some setting correctly to the canvas. But later I found that even the my MultiStreamMixer demo or the WebRTC demo (You can't see the text on the teapot clearly in the recording) generates blurry video with canvas.

    


    I'm asking in webrtc group to see if I can get around this issue. Meanwhile I looked into ffmpeg.js

    


    ffmpeg.js

    


    I think this would "work" but the file is too large. It's impratical to let the customer wait for this 23MB JS file to be downloaded.

    


    Other ways that I haven't tried

    


    The above are my investigations thus far.

    


    Another idea is to play the video and recorded video side-by-side and use screen recording API to record the merged version. (Example). But this would require the customer to wait for the same amount of time as the initial recording to get the screen/tab recorded.

    


    Uploading the video to server and doing the work in server would be my last resort.
