• Convert HEVC video to a more widely supported format using fluent-ffmpeg in Node.js

  21 juin 2021, par Daniel Loiterton

  My app allows users to upload videos from their phones. However, the latest iPhone default format (HEVC / H.265) does not seem to be supported by Chrome and other browsers, so some users cannot stream the videos.

  


  I'm already using fluent-ffmpeg on my Node.js backend to read metadata and extract thumbnails from the uploaded videos. How would I go about converting HEVC videos to something else ? What format/options would be appropriate for streaming to browsers ? Ideally I'd like to keep files fairly small, and I'm willing to sacrifice some quality to that end.

  


• Can you call out to FFMPEG in a Firebase Cloud Function

  27 juillet 2024, par Dave Parks

  Per the Firebase Cloud Functions documentation, you can leverage ImageMagick from within a cloud function : https://firebase.google.com/docs/functions/use-cases

  



  Is it possible do something similar but call out to FFMPEG instead of ImageMagick ? While thumbnailing images is great, I'd also like the capability to append incoming images to a video file stored out on Firebase Storage.

  


• Java, FfMPEG : Gson not found even though it's there.

  19 avril 2018, par We are Borg

  I am working on a Spring-MVC application in which we are using FFProbe to get media information. Unfortunately, it’s not working on our live instance. We have ffmpeg & ffprobe installed on same path. The error we get is GSON is not foudn, although we have it.

  Error log :

  Usage :

  Error thrown on first line.
  
  FFprobe ffprobe = new FFprobe("/usr/bin/ffprobe");
  
  FFmpegProbeResult probeResult = ffprobe.probe(filePath);

  I can confirm that ffprobe file is available on /usr/bin. What am I doing wrong here ? Thank you.
