CLI Syntax for input-codec=mjpeg

[Fibo27]

Hi Dusty
I am using Jetpack 5.1.1 on a Orin Nano on which I have compiled the ros_deep_learning module. I also have a robot running on a nano and it is streaming video on rtp.

1. On my Orin, I am able to view the streaming video using "video-viewer --input-codec=mjpeg rtp://@:1234"
2. Also, in jetson inference, I can run any of the modules on the incoming stream like "
   "./detectnet.py rtp://@:1234 --input-codec=mjpeg"
   However when i try to use any of the launch files (I am running Foxy on both the Orin and the Nano on the Robot)
   "ros2 launch ros_deep_learning detectnet.ros2.launch input:=rtp://@:1234 output:=display://0" I would expect to get an error which i get since the default input-codec is h264. Although you mention (as does the code) that the input codec can be changed, I get errors when i try either of the two options mentioned above i.e. using
3. ros2 launch ros_deep_learning detectnet.ros2.launch input-codec:=mjpeg input:=rtp://@:1234 output:=display://0
4. ros2 launch ros_deep_learning detectnet.ros2.launch --input-codec=mjpeg input:=rtp://@:1234 output:=display://0

Can you please help me the syntax for CLI? Thanks

@Fibo27 can you try adding this line of code under here:

ros_deep_learning/launch/video_source.ros2.launch

Line 14 in 84485b9

<param name="latency" value="$(var input_latency)"/>

<param name="codec" value="$(var input_codec)"/>

Unfortunately it appears that I missed that one for mapping input_codec, sorry about that.

Thanks Dusty - no need to apologize - you have done an incredible job with these repos.
The suggested change works like a charm. The syntax to be used is input_codec=mjpeg

On another note I had the issue which has been posted in 115 - it relates to ros_deep_learning not being found after colcon build. I had the same issue - since I am using Foxy - i removed lines 22 through 44, 85 to 92 and 111 in cmakelists.txt and ros1 related xml files from the folder - it solved the problem!

Ah okay!, great thanks 👍 glad you were able to get both those things working :)
