PixeLINK usb camera now works

[jeffhcon]

I made the PixeLINK-19962CE1E747-2CE1E747 usb camera work under aravis.

The PixeLINK-19962CE1E747-2CE1E747 usb seems to work at first but then the camera hangs. Try it with arv-viewer.

See the attached "values" output to describe the camera:

Platform description: Aravis 0.8.26

x86_64 Debian 11

The solution was to change src/arvuvstream.c

Double the size of the these macros:

#define ARV_UV_STREAM_MAXIMUM_TRANSFER_SIZE    (1024*1024 * 2)
#define ARV_UV_STREAM_MAXIMUM_SUBMIT_TOTAL     (16*1024*1024)

Rebuild, and it works fine.

I realize this is a total hack. If someone in the know can direct me to a proper solution, I would appreciate it. Thanks. Jeff

Hi @jeffhcon , thanks for the report

Could you attach the output of arv-camera-test-0.8 --duration=1 -d device,stream (with and without your patch)?
