Test device modules

This page is updated to the 2.0.0 release

For testing purposes, we've developed two mock sources, one for video and one for audio.

Audiotest and Videotest are two device modules providing autogenerated sources to test Galicaster without any device connected. They are configured in a similar way to regular device modules.

Videotest

Admmited values:

  • name: Name assigned to the device.
  • device: Device type: videotest
  • flavor: Matterhorn "flavor" associated to the track. (* presenter* |* presentation* |* other* )
  • location: Device's mount point in the system (e.g. * /dev/video0* ).
  • file: The file name where the track will be recorded.
  • caps: GStreamer capabilities of the device.
  • pattern: type of pattern to show. Run gst-inspect-0.10 videotestsrc fore more information. (0-20)
  • color1: pattern foreground color, indicated on Big endian ARGB. Run gst-inspect-0.10 videotestsrc fore more information. (0,4294967495)
    • color2: pattern background color, indicated on Big endian ARGB. Run gst-inspect-0.10 videotestsrc fore more information. (0,4294967495)

Pattern options

  • (0): smpte - SMPTE 100% color bars
  • (1): snow - Random (television snow)
  • (2): black - 100% Black
  • (3): white - 100% White
  • (4): red - Red
  • (5): green - Green
  • (6): blue - Blue
  • (7): checkers-1 - Checkers 1px
  • (8): checkers-2 - Checkers 2px
  • (9): checkers-4 - Checkers 4px
  • (10): checkers-8 - Checkers 8px
  • (11): circular - Circular
  • (12): blink - Blink
  • (13): smpte75 - SMPTE 75% color bars
  • (14): zone-plate - Zone plate
  • (15): gamut - Gamut checkers
  • (16): chroma-zone-plate - Chroma zone plate
  • (17): solid-color - Solid color
  • (18): ball - Moving ball
  • (19): smpte100 - SMPTE 100% color bars
  • (20): bar - Bar

Audiotest

Admmited values:

  • name: Name assigned to the device.
  • device: Device type: audiotest
  • flavor: Matterhorn "flavor" associated to the track. (presenter|presentation|other)
  • location: Device's mount point in the system (e.g. /dev/video0).
  • file: The file name where the track will be recorded.
  • file: The file name where the track will be recorded.
  • wave: Generated waveform sample. Run gst-inspect-0.10 audiotestsrc fore more information. (0-12)
  • frequency: Test signal central frequency. (0-20000)
  • volume: Percent volume of the pattern. (0-1)
  • vumeter: Activates data sending to the program's vumeter. (True|False) Only one device * `should be activated.
  • amplification: Gstreamer amplification value: < 1 decreases and > 1 increases volume. Values between 1 and 2 are commonly used. (0-10)
  • player: Whether the audio input would be played on preview. (True|False)

  • (0): sine - Sine
  • (1): square - Square
  • (2): saw - Saw
  • (3): triangle - Triangle
  • (4): silence - Silence
  • (5): white-noise - White uniform noise
  • (6): pink-noise - Pink noise
  • (7): sine-table - Sine table
