V4L2 API and OpenGL on IMX6Q?

byunggukchoi — Wed, 14 Feb 2018 01:39:18 GMT

I'm trying to capture images from web camera using V4L2 mmap API and process them with OpenGL for performance.

How to implement on I.MX6Q Sabre Auto hardware?

Thanks in advance.

Hi ByungGuk

for web camera one can use gstreamer and sect.7.3.10 Web camera

attached Linux Guide with NXP software BSPs described on

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6series-i.mx-7series-software-and-development-tool-resources:IMX_SW

There is support for V4L2 in NXP Linux BSPs and it is described in Chapter 9 Video for Linux Two (V4L2) Driver

attached Linux Manual. However for using it with web camera seems one will have to develop

custom drivers.

Best regards
igor
