• How can I play an MPG file using Electron on windows without converting it ? [closed]

  1er novembre 2024, par Indy Singh

  I am trying to play MPG files in an Electron app on Windows. The files contain mpeg1 encoded video. I am using the video element. I can play MP4 files, but the MPG files do not play. One requirement is to be able to play the video from some arbitrary start time.

  


  Electron uses the Chrome engine to render output. Google Chrome app also cannot play MPG files.

  


  Electron uses ffmpeg.dll to play the video file. As far as I can tell ffmpeg.dll contains the mpeg1 decoder, but the video element does not appear to make use of it.

  


  I know I can convert the video before playing, however conversion takes several minutes and is not an ideal user experience. As a fallback I can convert small segments as needed, which still takes a bit of time, so it is not ideal.

  


  Streaming the video from a server process with on-the-fly conversion is possible, but I believe it may not work well with the need to seek. I could be wrong here.

  


  Any other suggestions would be welcome.

  


  EDIT 1 :
I am developing an Electron App using the programming languages TypeScript, JavaScript and HTML5 and the tools Nodejs and Electron. I did not post a code snippet as I am looking for an approach, not a fix for code. Not sure why this question got flagged as being 'not about programming'.

  


  A Google search does not show many options other than those mentioned below.

  


  EDIT 2 :
Thanks to the suggestion from VC.One I am looking at the JSMPEG library. It does look like it could possibly do the job but with 'numerous limitations'. It also say the other alternative called Broadway is 'huge, compiled with emscripten and quite complicated'

  


  EDIT 3 :
I am now looking hls.js, which I think will likely work for my needs. It integrates well with using the html5 video element. I can use it with on-demand decoding of the MPG MPEG1 video file in small segments.

  My projector is connected at 1920x1080 59.9

  How I can force a graphic card to give output at 25fps or How I can play 25 fps video smoothly with 59.9 refresh rate.
