ROS2 image transport for Foxglove CompressedVideo messages
This plugin provides a ROS2 image transport for encoding messages in Foxglove’s CompressedVideo
message format, using the FFMpeg library.
These messages can be recorded in a rosbag for processing with e.g. Foxglove Studio.
There is also an unsupported decoder provided for testing purposes. Use at your own peril.
Supported systems
Continuous integration is tested under Ubuntu with the following ROS2 distros:
Installation
From packages
sudo apt-get install ros-${ROS_DISTRO}-foxglove-compressed-video-transport
From source
Set the following shell variables:
repo=foxglove_compressed_video_transport
url=https://github.com/ros-misc-utilities/${repo}.git
and follow the instructions here
Make sure to source your workspace’s install/setup.bash
afterwards.
If all goes well you should see the transport show up:
ros2 run image_transport list_transports
should give output (among other transport plugins):
"image_transport/foxglove"
- Provided by package: foxglove_compressed_video_transport
- Publisher:
This plugin encodes frames into foxglove compressed video packets
- Subscriber:
This plugin decodes frames from foxglove compressed video packets
Remember to install the plugin on both hosts, the one that is encoding and the one that is decoding (viewing).
Parameters
Publisher (camera driver)
Here is a list of the available encoding parameters:
-
encoding
: the libav (ffmpeg) encoder being used. The default islibx264
, which is on-CPU unaccelerated encoding. Depending on your hardware, your encoding options may include the hardware acceleratedh264_nvenc
orh264_vaapi
. You can list all available encoders withffmpeg --codecs
. In the h264 row, look for(encoders)
. -
preset
: default is empty (“”). Valid values can be for instanceslow
,ll
(low latency) etc. To find out what presets are available, run e.g.fmpeg -hide_banner -f lavfi -i nullsrc -c:v libx264 -preset help -f mp4 - 2>&1
-
profile
: For instancebaseline
,main
. See the ffmpeg website. -
tune
: See the ffmpeg website. The default is empty(“”). -
gop_size
: The number of frames between keyframes. For foxglove, this must be set to 1. The larger this number the more latency you will have, but also the more efficient the transmission becomes. -
bit_rate
: The max bit rate [in bits/s] that the encoding will target. Default is ``8242880`. -
delay
: Not sure what it does, but doesn’t help with delay. Default is empty (“”). -
pixel_format
: Forces a different pixel format for internal conversions. Experimental, don’t use. -
qmax
: Max quantization rate. Defaults to 10. See ffmpeg documentation. The larger this number, the worse the image looks, and the more efficient the encoding. -
measure_performance
: For performance debugging (developers only). Defaults to false. -
performance_interval
: How many frames to wait between logging performance data.
The parameters are under the foxglove
variable block. If you launch
your publisher node (camera driver), you can give it a parameter list on the way like so:
parameters=[
params_path,
{
'.image_raw.foxglove.encoding': 'h264_vaapi', # 'libx264'
'.image_raw.foxglove.profile': 'main',
'.image_raw.floxglove.preset': 'll',
},
],
See the example launch file for a V4L USB camera
Subscriber (viewer)
The subscriber plugin is used for debugging purposes and is not supported.
Setting encoding parameters when launching camera driver
The launch
directory contains an example launch file cam.launch.py
that demonstrates
how to set encoding profile and preset for e.g. a usb camera.
