V5L recorder tool, can't record more than 2 cameras when use h264/lraw format

Autonomous Vehicles DRIVE PX 2 DriveWorks
1

Does there is any plan to release patch or update to fix it?

V5L version : 5.0.5.0
Device: Drive PX2 : autoCruise (P3470) & autoChauffeur (P2379)
Firmware Version : 4.02.02.00

whe use h264 as format;

plus : I ran prerecorder-checker was working. (3 cameras, lraw format)
The result is Ok with 3 cameras and GPS.
But there still many driveworks exceptions thrown.

seem the screenshot as below.

Dear d0121006,

May I know did you run recorder-qt with raw format option? is it OK?
And could you please help to check this topic after reboot the system? Thanks.

Hello,

I have similar issues, I can’t use recorder-qt to record raw but h264 is fine.

h264 config.json file:

"camera": {
        "separate-thread": true,
        "record-thread-priority": 0,
        "write-file-pattern": "camera_*",
        "sensors": [
          {
                "protocol": "camera.gmsl",
                "params": "camera-type=ar0231-rccb,csi-port=ab,camera-count=2,camera-mask=0011,output-format=h264,fifo-size=6,async-record=0",
                "channel-names": ["ab_0","ab_1"]
          },
          {
                "protocol": "camera.gmsl",
                "params": "camera-type=ar0231,csi-port=cd,camera-count=1,camera-mask=0001,output-format=h264,fifo-size=6,async-record=0",
                "channel-names": ["cd_0"]
          }
        ]
    }

raw config.json file:

"camera": {
        "separate-thread": true,
        "record-thread-priority": 0,
        "write-file-pattern": "camera_*",
        "sensors": [
          {
                "protocol": "camera.gmsl",
                "params": "camera-type=ar0231-rccb,csi-port=ab,camera-count=2,camera-mask=0011,output-format=raw,fifo-size=6,async-record=0",
                "channel-names": ["ab_0","ab_1"]
          },
          {
                "protocol": "camera.gmsl",
                "params": "camera-type=ar0231,csi-port=cd,camera-count=1,camera-mask=0001,output-format=raw,fifo-size=6,async-record=0",
                "channel-names": ["cd_0"]
          }
        ]
    }

prerecord-checker works with both config files.

When pressing the start recording button in recorder-qt with the raw configuration file it exits and throws the following errors in the terminal:
