  • How to manipulate large media files in Node.js in a non-blocking way

    26 août 2017, par Jacob Prud'homme

    I am currently creating a Node.js app that receives an audio/video stream, writes it progressively to the disk, then transcodes it with ffmpeg once the stream has ended and sends it somewhere else to be stored, deleting it locally.

    Besides the fact that I can transcode the stream before writing it to streamline the entire thing (this feature is planned), what is the best way to handle these operations on potentially large files ?

    I am aware of spawing child processes (the method I’m currently using), but I’m not sure how they actually function, even after much reading. I’m not even sure using "spawn" is exactly what I want here (is "fork" a better option ?).

    Essentially, I want to know how to transcode -> upload -> delete the file without blocking Node.js so that multiple users can do the same thing simultaneously. Also, I am thinking of putting all 3 operations in a single bash script so that they happen synchronously in sequential order, is this fine ?

  • How to stream WEBM Video by Media Source Extensions API

    4 octobre 2023, par Mahmoud Khudairi

    I'm developing video streaming website using MSE.

    


    Each video converted to FragmentedMP4 (h264,aac => avc1,mp4a)

    


    It is working very fine but what if I wanted to use webm format ? like YouTube or Facebook they sometimes use it.

    


    I want to know how to get index (like sidx atom in fmp4) from VP8, VP9 or vorbis codec
I use bento4 and ffmpeg to get metadata from video and audio
but bento4 is for MP4 Just, and use MP4BoxJS to parse index in browser by JavaScript.

    


    What should I use ? ffmpeg or what to create fragmented webm or something like that and get index stream info to append segments to MSE SourceBuffer and sure it should be seekable stream..

    


  • How can I record video with FFMPEG in ISO BMFF format ready for Media Source Extensions ?

    17 novembre 2015, par Matt

    I’m trying to record video using ffmpeg and then play it back on a player using MSE. Here’s the script I’m using :

     ffmpeg -i /dev/video0 -c:v libx264 -profile:v baseline -level:v 13 -g 250 -r 25 -keyint_min 250 -strict experimental -pix_fmt yuv420p -movflags frag_keyframe+empty_moov -b:a 96k sintel.mp4

    This works except for the fact that there is an mfra box at the end of the video file, which I believe is not supported by MSE. How can I remove this mfra box ?
