Description (last modified by bennylp)

Support for the open source implementation of H.264 codec from http://www.openh264.org.

Implementation features:

  • packetization modes: 1, 0
  • key frame request and indication
  • obey remote's fmtp

Notes:

  • currently transmission is hard coded to use only single NAL (packetization mode 0) regardless of remote's fmtp for interop reason. The same is also done in ffmpeg wrapper.
  • whole frame for file encoding is implemented but currently doesn't work

Below are the steps to use the codec:

For GNU targets:

  1. Run configure with --with-openh264 option specifying the directory of OpenH264 source files. E.g.:
    ./configure --with-openh264=/home/user/src/openh264-trunk
    
  2. Add this to your config_site.h:
    #define PJMEDIA_HAS_OPENH264_CODEC		1
    

For Visual Studio:

  1. Add this to your config_site.h:
    #define PJMEDIA_HAS_OPENH264_CODEC		1
