sample_camera is a single-threaded application designed to demonstrate the use of SAL APIs, and frame drops can occur when using multiple cameras. For improved performance and synchronization in such scenarios, we recommend utilizing the recorder application. This application is better suited to handle multiple cameras effectively.
Vick , can you give more specifics on recorder application? what is the path for this in driveworks ?
Please check Recording Tools located under /usr/local/driveworks/tools/capture for more specifics on the recorder application.
where can we find the source for this tools ? Just the tool doesnt help us. So this tool is just used only for recording and no rendering on to screen ?
vick, is this recorder application tested by nvidia ? if so for how many cameras ?
I see with 8 cameras even with this recorder application ICP_FRAME_DROP being reported.
The source code for these tools is not provided. Regarding rendering, you would need to implement your application based on the sample_camera code, as the tools primarily focus on recording functionality.
Yes, the recorder application has been tested in conjunction with Hyperion for data collection. For the ICP_FRAME_DROP issue you’re experiencing with 8 cameras, I recommend creating a new topic (linked to this sample_camera one) this and providing the relevant details for further assistance.
got it. Yeah i think the solution should be a multithreaded application . I get your point now. thank you. may be we can close this case, saying that sample_camera is not a solution for multiple cameras
Thank you for your understanding. If you have any more questions or need further assistance on the recorder application, please don’t hesitate to reach out.
