Hi, I am running a custom Deepstream application based on the Deepstream reference app. I have an HDMI capture card connected that is connected to a video input source (in this case just another computer playing videos). the Deepstream is running as a live-source inferencer on the video input. I have the following strange behaviour:
- If I start the application with the input source plugged into the HDMI input, I have a small delay (roughly 0.5 to 1 second) between the input and what is shown on the Jetson OSD. If I unplug and re-plug the input, the delay disappears.
- If I start the application without an input source plugged into the HDMI input, and then plug it in once the application is running, there is also no delay.
If I set the FPS rate at 30 instead of 60, the delay disappears. However, I would like my application to run at 60FPS; and the scenarios above show that it is at least feasible.
I figured it may be something with timestamp/buffering issues, but can’t seem to find a fix. Please find below my configuration file:
