Nodes

video_player

This node has two main functions.

It can play a video.avi-file with the VLC-Media-Player and closes automatically after playing back the file.
It can publish the video-data to a topic, which the ROS environment can deal with. The modus can be changed in the launch file.

Parameters

mode (string)

Describes in which way the node works (VLC-playback, ROS-stream). "mode_I" => VLC player, "mode_II" => ROS-stream. Default: "mode_II" = ROS-stream.

gscam_config (string)

Used for calling the gstreamer. Example: "filesrc location=~/catkin_ws/src/tools_robin/video_player/data/Video1/Video.avi ! avidemux name=demux demux.video_00 ! decodebin ! ffmpegcolorspace ! video/x-raw-rgb ! identity name=ros ! fakesin";

test_client

A simple node to test the video_player.

Launch Files

video_player.launch - Launches the video_player_node.
