  • [DH] libavformat/hlsenc.c

• FFmpeg : Read profile level information from mp4

  31 mars 2016, par Martin

  I have a mp4 file and need the profile level of it. FFmpeg says, it has baseline profile, which is what I need, but I need also the level.

  Here is what I get from FFmpeg :

  At least one output file must be specified

  Is there any option other than -i I can use to get the level information ?

• How to use PHP FFMPEG to alter audio binary header bytes offset

  27 mai 2019, par SomniusX

  I use the following method to create a WNB file that is flashable to my Electric Unicycle Ninebot Z10

  First audacity to make the file raw pcm 16khz 16bit mono littleendian
  Then wnb-slicer golang app to convert that raw file into wnb.

  Today i did the same with ffmpeg

  ffmpeg -i $1 -acodec pcm_s16le -f s16le -ac 1 -ar 16000 -acodec pcm_s16le $1.raw
  
  ../wnb-slicer-master/wnb-slicer -file-name $1.raw

  where $1 is the original file

  About an hour ago i did the ffmpeg part with php-ffmpeg but i can’t have golang run on a webserver.

  So i thought if ffmpeg does bytes manipulation like the golang app does here

  Thank you in advance !

  p.s. this project will help all electric unicycle owners of the Z series wheels to change audio voices/sounds on their wheels !!
