Streamline recording only captures ~1 second

Chloe Tibets

New to streamline. Testing out an unreal engine based application on the Vive Focus 3 headset, it will only record around a second of data. It won't prompt that it failed, but when you stop recording you get just .8s seconds of data. Also, I do not get any live streamed data while recording.

Unsure why this could be happening, the application uses OpenXR if that helps.

    Hi,

    The capture log is truncated and the capture itself does not indicate reason of failure.

    Would it be possible to run local on-target capture with debugging on:

    1. Push gatord profiling agent to the target: adb push <ArmPerformanceStudio_dir>/streamline/bin/android/arm64/gatord /data/local/tmp
    2. Run local capture: adb shell '/data/local/tmp/gatord -S no -l com.HTXLabs.EMPACT -m com.epicgames.unreal.GameActivity -d -o /data/local/tmp/local_capture.apc > /data/local/tmp/gator-debug.txt 2>&1' (if needed, add "-t <n>" to set capture time in seconds)
      1. Pull profiling assets from the target: adb pull /data/local/tmp/{local_capture.apc,gator-debug.txt} .
      2. Send back zipped local_capture.apc directory and gator-debug.txt

      Also it would be worth to capture logcat output while taking the capture. 

      Thanks

        Hi Michal, 

        I have gotten gatord onto the target, but am having issues getting a local capture to happen. I've checked and confirmed gatord is on device, and can see a gator-log.txt and gator-debug.txt on device. Any other ways / commands to get a local capture to start?

        I will also send over a logcat from a recent attempt, unsure if it will be of any help.
