Description

There are some problems showing from logs below.

  1. Many Error saving frame to SVO errors when starting recording
  2. Core dump when write svo file failed, referring to end of logs below
  3. Error when stopping recording (EDIT: when compression_mode is 1, i.e. H264. No such error when it's 0)
    [ERROR] (/builds/sl/ZEDKit/lib/src/sl_input/mmapi/R364/NvV4l2ElementPlane.cpp:256) <�,���> Capture Plane:Error while Qing buffer: Device or resource busy
  4. What is the meaning by NVMEDIA: Need to set EMC bandwidth : 2872000 , is it a error?```
  5. SVO frame rate and frame number mismatch. ZED_SVO_Editor says frame rate is 30 fps, but according to recording duration( ~ 20 seconds), frame number should be about 600, actually it's about 300. And I have tried compression_mode 0(png) and 1(h264). Same result. Besides, replay svo within ZED_Explorer, frame rate is 15 fps! Which is right? And why?

Steps to Reproduce

  1. (Terminal 1) Bringing multi-cameras nodes up by
    ros2 launch zed_multi_camera zed_multi_camera.launch.py cam_names:=[cam0,cam1] cam_models:=[zedx,zedx] cam_serials:=[48895327,47293210]
  2. (Terminal 2) Recording by calling recording service
    ros2 service call /cam1/zed_node_1/start_svo_rec zed_msgs/srv/StartSvoRec "{bitrate: 0, compression_mode: 1, target_framerate: 0, input_transcode: false, svo_filename: /media/vt/test0.svo2}"
  3. (Terminal 2) Stop recording
    ros2 service call /cam1/zed_node_1/stop_svo_rec std_srvs/srv/Trigger

Expected Result

Recording a normal svo file with no errors.

Actual Result

svo file is generated and save but with errors.

The saved svo file can be opened by ZED_Explorer, but with strange frame rate. Don't know if it has relationship with these errors.

ZED Camera model

Environment
