• Electron ffmpeg integration

  27 avril 2017, par Raider Dave

  I am in way over my head here. I am normally a coldfusion/javascript/jquery developer but now have taken on a task that assumes I know more than I do.

  I am trying to write an application in electron that will allow me to select a group of video files and convert them to mp4 files while also compressing them. The files are football plays and a normal game consists of about 160 plays and 18gb. We need to compress these down to about 4gb. I have used programs like Prism to do this, but the intended users are not technically savvy nor do they all have windows - some have Macs.

  I have an electron project that I have started and got the first part to work. I can start the app and select the input files. But I have tried all kinds of different solutions found online to call ffmpeg and pass it the parms to convert a file. Is there an easy way to call ffmpeg with parms and then wait for it to finish before continuing ?

  I am on Windows 10 but will also need to run on Apple OS. Please, if you have a simple example of how to do this, I would appreciate it.

  Thanks !
  Dave

• Restreaming video containing two languages live with ffmpeg

  9 novembre 2012, par user1810837

  I have a project where i need to restream a live stream which has two languages setup on the audio.
  Spanish on left and English on right

  The stream mapping is :

  Stream #0:0: Video: h264 ([7][0][0][0] / 0x0007), yuv420p, 512x288 [SAR 1:1 DAR 16:9], q=2-31, 1k tbn, 1k tbc
  
  Stream #0:1: Audio: mp3 ([2][0][0][0] / 0x0002), 44100 Hz, stereo, s16, 18 kb/s

  I need to restream this back live with just the English from the right side or just spanish from the left side, I tried looking everywhere but did not find any type of solution .

  Since this needs to be done live, I can't be using other programs to separate video and audio to get it done.

  This needs to be done through ffmpeg and I wonder if it even capable of doing so with original built or it would need some custom modification.

• ffprobe Input buffer exhausted before END element found

  9 juillet 2021, par puneet jain

  While fetching the stream details with ffprobe getting Input buffer exhausted before END element found saw few other similar errors reported but the solution was more of to fix it using the audio separately and kind of recompiling it.
How can I handle it without adding a new compilation ?

  


  ffprobe -loglevel error -select_streams v:0 -show_entries stream=width,height:stream_tags=rotate  -of json testVideo.mp4

{
[aac @ 0x7fc06201cc00] Input buffer exhausted before END element found
