Device Scripts for a profile

From 1.3 every profile can establish a configuration script. The script will be executed before the profile is loaded.
Usually a script will configure a certain device but it could include any other task.

To specify the script to be executed include is full path on the profile data section

name = profile
script = /home/user/scripts/script1.py

Configure a Logitech c920 to a power line frequency of 50Hz

v4l2-ctl -d /dev/webcam -c power_line_frequency=1

Configure Encoder and Muxer

Most of the device plugins of Galicaster are now able to configure the encoder and muxer where the data will be stored.
Exceptions include:

  • Hauppauge can't define the encoder nor the muxer.
  • RTP only allows to define the muxer

Parameters and examples:

  • videoencoder
    • x264enc quantizer=22 speed-preset=2 profile=1
    • xvidenc bitrate=50000000
    • ffenc_mpeg2video quantizer=4 gop-size=1 bitrate=10000000
  • audioencoder
    • lamemp3enc target=1 bitrate=192 cbr=true
  • muxer
    • flvmux
    • avimux
    • mpegtsmux

Note: Pulse parameter is encoder not audioencoder, this denomination will be modified for the next RC.

To know more of the paramaters of each muxer and encoder consult the Gstreamer documentation. Consult us for instructions to configure your custom encoder and muxer.
