PVRCarbon (and player) for IVI-shell

PowerVR Insider

Hello,
I have this two questions:

1.) PVRCarbon tracing
How to capture correctly a trace with PVRCarbon for weston IVI-shell ?
Weston IVI-shell — weston 12.0.90 documentation (pages.freedesktop.org)

2.) PVRCarbon replaying
LD_PRELOAD=<library.so> ./PVRCarbonPlayer --ws=??? .pvrcbn
What is the correct command to replay this trace file from IVI-shell ?

Thanks and Best Regards
Gotthard

Hi Gotthard,

When taking recordings in IVI-shell the method used for standard linux recording should work.

For playing back recordings, ./PVRCarbonPlayer recording_name.pvrcbn should work as long as the player is able to detect the windowing system. If it is not detected, then you can use the parameter --ws= to match the setup you are using (possibly wayland or x11).

Please let me know if you come across any issues when taking or playing PVRCarbon recordings.

Best regards,
Alejandro
