• Why won’t this mp4 play in a video-js tag any longer

  18 octobre 2019, par Velocedge

  I’m using ffmpeg to convert files to MP4. I’ve made some modifications to the ffmpeg string but now it seems no matter what I use, the video won’t play in an HTML5 tag (Chrome browser). Normally, I just used "-vcodec libx264 -s 1280x720 -ar 22050". When I try to load it in the video tag, I get the following error on http://family.gotsport.net/lmw/GotSport/videoPlayer.asp?WS=1&URL=/VideoFiles/2/4_70_highlight :

  The media could not be loaded, either because the server or network failed or because the format is not supported.

  No matter what parameters I use (or don’t use), it still won’t play. However, if you just call the url directly, it will play in Chrome (http://family.gotsport.net/videofiles/2/2_70_highlight.mp4). I’m using the 7.0.0 version of video-js from their CDN (although older versions give the same result).

  Video tag looks like :

  <video class="video-js vjs-default-skin" autoplay="autoplay" controls="controls" preload="auto"> 
  
      <source src="/VideoFiles/2/4_70_highlight.mp4" type="video/mp4"></source>
  
  </video> 

  Here is the MediaInfo output from the file that won’t play :

  Do you see anything that would keep this format from playing in an HTML5 video tag ?

• Convert m3u8 File URL to a GIF File [closed]

  30 juin 2023, par nxsi

  I have a m3u8 File URL that I got using the MusicKit API (Apple Music) which is an animated cover art for an album. (A quick side question on that. Is m3u8 the only format that Apple Music returns for animated cover arts ?)

  


  So, Now that I have that m3u8 file URL, I want to convert it to a GIF for the ease of use of GIFs.
I've tried using ffmpeg but I don't really seem to make it work at all with NodeJS.

  


  Here is a sample File URL of what Apple Music returns (https://mvod.itunes.apple.com/itunes-assets/HLSMusic116/v4/cb/ac/9e/cbac9e42-0c8a-9798-0016-52ce447cdc78/P359486356_default.m3u8)

  


  TLDR ;
1- Is m3u8 the only format of animated cover arts that the MusicKit api returns ?
2- Can I convert that m3u8 file URL to a GIF, If so, How ?
3- Are there any other ways than ffmpeg to use in NodeJS ?

  


  I've tried using ffmpeg and the furthest I got was a GIF that was corrupted and not done correctly.
Here is the command I tried :

  


  ffmpeg -i "https://mvod.itunes.apple.com/itunes-assets/HLSMusic116/v4/cb/ac/9e/cbac9e42-0c8a-9798-0016-52ce447cdc78/P359486356_default.m3u8" -vf "fps=10,scale=320:-1:flags=lanczos" output.gif
