• How to bundle a precompiled binary into an electron app

  1er mai 2023, par Aiotex

  I'm developing an Electron app that uses discord/opus which requires ffmpeg to work. I've downloaded a precompiled binary of FFmpeg for my operating system windoes and I want to bundle it with my Electron app.

  


  I've already tried using npm packages like ffmpeg-static and also tried many solutations such as this one : https://github.com/ganeshrvel/tutorial-electron-bundle-binaries, but I can't get the package to use the binaries I download and instead I just get this error : "Uncaught Error : FFmpeg/avconv not found !"

  


  I'm not sure how to bundle the precompiled binary with my Electron app. Do I need to use any specific build tools or can I simply copy the binary into the app's bin folder ? How do I access the FFmpeg binary from my Electron app ?

  


  Can someone provide step-by-step instructions or point me to a tutorial that explains how to bundle a precompiled binary of FFmpeg into an Electron app ?

  


• Preserve attached picture by cutting audio file with FFMPEG [closed]

  29 avril 2023, par Riccardo Volpe

  I know that there are similar topics already opened and answered here, but none of them can explain what is happening to me :

  


  I need to cut an audio file which has a picture attached to it.

  


  If I do :

  


  ffmpeg -i input.mp3 -ss 00:00:04.50 -t 00:03:07.16 -map_metadata 0 -c:v copy -disposition:v:0 attached_pic -ar 44100 -b:a 320k -f mp3 output.mp3


  


  it doesn't work, that is the output.mp3 file doesn't maintain the original attached cover.

  


  I need to do a three steps job to achieve it :

  


  ffmpeg -i input.mp3 -an -c:v copy -update 1 cover.png

ffmpeg -i input.mp3 -ss 00:00:04.50 -t 00:03:07.16 -c copy output_cut.mp3


  


  in the previous last step I receive a warning about the missed picture which I'm going to add in the following third and last step :

  


  ffmpeg -i output_cut.mp3 -i cover.png -c copy -map 0 -map 1 output.mp3


  


  It works, but here I would ask you if there is a way to do it with just one FFMPEG command, thank you.

  


• Convert video with FFMPEG Library in android

  30 septembre 2017, par Sanat Pandey

  I have a problem that I received a video file from the server which can not be played through video view from the app I am making. I don’t know what the actual problem is because all videos are played through same video view but the video received from the server side is not played. So, I think that I have to integrate FFMPEG in our android app, so I can play every video at a runtime conversion. For this, I have read much more about FFMPEG Library integration with Android through many sites as :

  http://www.roman10.net/how-to-build-android-applications-based-on-ffmpeg-by-an-example/

  Downloaded some projects from GitHub (https://github.com/appunite/AndroidFFmpeg) but unable to succeed in building the Library through NDK. Something I missed and I am working on Windows machine, probably this might be a problem. I want the exact solution regarding this, means step by step solution for building the android project with FFMPEG Library. If you have some useful suggestion then please share with me.
