• Use a video editing library (not executable) via Node [on hold]

  25 septembre 2018, par Merc

  I need to edit clips using node. I am looking around, and most (if not all) libraries seem (like Fluent FFMpeg) seem to be based on the fact that they run FFMPEG as an executable and get the resulting output.

  That’s not what I want. I worked with FFMPEG executable in the past, and I know how flaky it is in terms of return codes and error codes.

  Ideally, I would love to find a native library for video editing and make calls using node.

  In terms of libraries :

  • Gstreamer
  • FFmpeg/LibAV (does they come with C libraries to bind to ?)
  • libVLC

  In terms of binding with them :

  • node-gir. Gstreamer seems to have updated git files

  • native bindings. For example Gstreamer has gstreamer-superficial. I couldn’t find any javascript bindings forFFMPEG — only "run the executable and hope for the best" libraries

  • VLC has a bindings library that is quite old and had its last commit years ago.

  Am I getting this all wrong ?
  My ideal outcome is to have a nice, robust library that I use directly using node, but my lack of experience in terms of using native libraries, and the somehow fragmented world of video editing libraries.

• Tagline challenge : what’s in a tagline ?

  23 octobre 2018, par Joselyn Khor — Marketing

  

  Our new website needs a new tagline !

  We’ve been going with the words “liberating analytics” for a few years and believe it’s time for a refresh.

  Coming up with a new tagline is leading to a few sleepless nights so we’ve decided to reach out to you guys to see if you’re up for a challenge.

  We’ve tried a few options but they don’t seem quite right, just yet :

  “Complete analytics”
  “All-in-one analytics”
  “Your analytics”
  “Beyond analytics”
  “Analytics for humans”

  We’ve gone through about 46 so far and none have stuck so we want your ideas. Are you feeling the options above, or can you (surely) come up with one even better ?

  Leave it in the comments section of our Mastodon, Facebook, Twitter pages, DM or post about it. You can also get in touch through the site ! Do whatever is necessary to let us know. Have what it takes to think of a tagline for a global analytics company ?

• ffmpeg recoded mp4 files error on mobiles in Video JS

  10 janvier 2019, par KJS

  We are converting seriously old .flv files to MP4 with FFMPEG. These are at least 10 years old.
  Back then all were rendered with early versions of Adobe Premiere.

  On desktop browsers all the files work and stream (...watching them feels like going back a century !)

  But when requesting the videos on the same pages on mobile devices (android and ios) Video JS doesn’t even show up.
  Perhaps the codec is just too old, but I was wondering if there could be another reason when converting them with this line :

  for i in *.flv; do ffmpeg -i "$i" "${i%.*}.mp4"; done

  If not, is it possible to detect this in Video JS, so we can show an announcement that the video is only visible on desktops ?

  I hope someone here has this knowledge !
