• ONVIF Device Manager API and Decoder

  10 juillet 2023, par spiderelite

  I'm working on the source code of the onvif device manager software and I want to find the Api and decoder it uses.

  


  I first separated the odm.player part of the code into another solution and built it separately. the separated part contains these parts from the source code (in order of execution) :

  


  utils.linq
utils.diagnostics
utils.common
odm.player.lib
odm.player.media
live555
odm.player.net
utils.xml
utils.bootstrapping
odm.player.host


  


  Im tring to find the decoder and Api it uses(in the above parts) to decode the media. i need to find the specific part of the program to contain some information from a decoder.

  


  I know the source code is using ffmpeg and live555 libraries but I need to find their use and API in the odm.player part.

  


  I checked odm.player.host because it is the last project and depends on previous ones, but didn't find anything.

  


  what should i do next ? is there any official documentation of the API ? is there any important keyword related to ffmpeg that can I search it in the code ?

  


• Android NDK & FFMPEG : libffmpeg.so is not getting created

  20 février 2015, par Palak Darji

  I am using this to build ffmpeg on ndk :
  roman10’s android ndk r9d - ffmpeg tutorial

  I am able to run build_android.sh script. I am getting libavcodec-55.so and all that files under android folder. But I am not getting this : libffmpeg.so

  The link shows how to compile, but its not clear how to use it. Can anybody guide me ? Thanks.
