C API example to take in 8bit PAL grayscale (parallel) and display on HDMI

jeanmitchel — Sun, 21 May 2017 09:33:55 GMT

Hi,

I am a total newbie at iMx (6 in my case) and kind of lost my mind while browsing through documentation. I'm a bit surprised by the lack of examples, I only found those in a git repo often referred to in iMx documentation. If I look in the wrong place, please show me where to search.

I am trying to read in 8b grayscale parallel video data in PAL format, perform a simple rotation and display the result on HDMI and i would like to do so using the C API's.

As i read from documentation, this format is unlikely to be directly supported by the IPU for on-the-fly processing, correct?

How even to start?

Thanks!

Hi Jean

right, on-the-fly processing is not supported on generic format.

For examples of such format one can check
