• Set protocol-level metadata in AVFormatContext any time a packet is read.

  1er août 2014, par Andrew Stone

  Set protocol-level metadata in AVFormatContext any time a packet is read.
  If any option named "metadata" is set inside the context, it is pulled up to
  
  the context and then the option is cleared.

• How to make a nonstreamable mp4 streamable from a JS browser client ?

  14 mai 2020, par Daniel Kobe

  For my service we are sending videos that need processing. Unfortunately some of the videos are non streamable. By that I mean the metadata information is at the end of the file and not the beginning. With ffmpeg you can make a video streamable with this command : ffmpeg -i source.mp4 -a:v copy -a:c copy -movflags faststart output.mp4

  



  Is there anyway I can replicate ffmpegs faststart logic from a JS client ?

  



  I see that there are libaries like ffmpeg.js but I was hoping to avoid having a huge library in the code.

  


• FFmpeg loglevel with level prefix

  13 mai 2020, par Matan Marciano

  I want to add level prefix to ffmpeg logs.
Im using ffmpeg -loglevel level+info -i input
And it is working as well in my Mac (ios) but is not working in my Ubuntu 18 with ffmpeg version 3.4.6-0ubuntu0.18.04.1

  



  When I am running it in my Ubuntu I got :

  



  Invalid loglevel "level+info". Possible levels are numbers or:
"quite"
"panic"
...
...
...
"trace"


  



  Please advise
