• Flash, Google, VP8, and the future of internet video

  23 février 2010, par Dark Shikari — H.264, HTML5, Theora, VP8, google, x264

  This is going to be a much longer post than usual, as it’s going to cover a lot of ground. The internet has been filled for quite some time with an enormous number of blog posts complaining about how Flash sucks–so much that it’s sounding as if the entire internet is crying wolf. But, of [...]

• hls.js not resolving segment file paths correctly for files hosted on S3 and accessed via cloudfront [closed]

  25 juillet 2024, par Kunal

  I've a HLS video upload on an S3 bucket with following folder structure

  


  https://bucket-name.us-west-1.amazonaws.com/folder/path/to/video/output.m3u8


  


  The contents of output.m3u8 file as following :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:18
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:11.011000,
output0.ts
#EXTINF:13.446767,
output1.ts
#EXTINF:7.273933,
./output2.ts
....
.....
....
#EXTINF:1.468133,
output48.ts
#EXT-X-ENDLIST


  


  The HLS segment and playlist file have been created using ffmpeg as below

  


  ffmpeg -i video.mp4 -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls video/output.m3u8


  


  The HLS.js library tries to download segment files from urls as below, completely ignoring the folder/path/to/video part of the url.

  


  https://bucket-name.us-west-1.amazonaws.com/output0.ts
https://bucket-name.us-west-1.amazonaws.com/output1.ts
https://bucket-name.us-west-1.amazonaws.com/output2.ts


  


  I tried the same HLS video/playlist url with video.js player and that seems to be correctly fetching the segment files, but unfortunately I am restricted to using hls.js and need to make this work, what might I be doing ?

  


  I want to avoid writing absolute segment paths in m3u8 file because its likely that we may change the domain we serve from bucket-name.s3.amazonaws.com to some CDN like cloudfront or maybe even a custom domain, so flexibility will be nice.

  


  I tried manually editing the output.m3u8 file to absolute url of segment files, that worked but is not viable/scalable solution it seems

  


• System.Diagnostics.Process calling FFMPEG fails with international character

  1er septembre 2013, par Petter Brodin

  I'm using System.Diagnostics.Process to launch FFMPEG, and it works as intended on paths that only contain non-special characters.

  string strParam = "C:\myFolder\foo.png";
  
  
  
  Process ffmpeg = new Process();
  
  
  
  ffmpeg.StartInfo.UseShellExecute = false;
  
  ffmpeg.StartInfo.RedirectStandardOutput = true;
  
  
  
  ffmpeg.StartInfo.FileName = Path_FFMPEG;
  
  ffmpeg.StartInfo.Arguments = strParam;
  
  
  
  ffmpeg.Start();
  
  
  
  ffmpeg.WaitForExit();

  The above example works perfectly, but if I use "c :\myFolder\føø.png" I get the following error message :

  Could find no file with path 'C.\myFolder\f├©├©.png'

  This looks like some kind of encoding error, but that's where my ideas stop.
