• Hls.js record file

  28 février 2023, par Huhngut

  Hello and thanks for reading,

  


  I have a Hls stream with an m3u8 playlist.
The Video is playing just fine on an Html page with a Video element and https://github.com/video-dev/hls.js

  


  But if I download the segments to join them they are only white pixels. VLC and FFmpeg can't handle them. VLC shows a white pixel for 10seconds and FFmpeg says that there's no stream in the file.

  


  So now I want to know what this hls.js is doing to make it running. To me a non-js developer it all looks a bit confusing. I was able to understand stuff like which function is called when a new segment is loaded. Unfortunately, I was unable to understand stuff about the data. The one character variables are confusing to me.

  


  For now, I capture the stream of the video element and download it later but I don't like this solution at all.

  


  How to help me

  


  


  It would be very nice if anyone can tell me how to hook into the
script and tell it to download directly to the disk so I'm independent
of framerate drops.

  


  If anyone can tell how the script is able to convert the data so that
the element can use it and I would be able to implement or do
it with FFmpeg would be really helpful.

  


  I also thought it might be possible to have a listener when the blob
changes to store its contents.

  


  


  Thanks for everyone helping. I'm trying to find a solution for too many hours now.

  


• Reducing FFmpeg dlls to only what is used ?

  1er juin 2021, par XylemFlow

  I have written Windows software that calls the FFmpeg dlls to encode a sequence of images in a few different formats (animated gif, animated png, mpeg4, wmv, webm). I need to provide the dlls with my software but they significantly increase the download size. Even after zipping everything they increase the size from around 5MB to around 20MB. This isn't a huge problem but I'd like to get the download size down as much as possible.

  


  How easy is it to do this and by roughly how much would I be able to reduce them ? Note that I don't need any decoders and am only encoding those 5 formats. I'm not using any special filters and the encoded videos don't have sound. I'd like to know if it's worth it before I start trying to compile the FFmpeg source and playing with configuration flags.
