what chroma types are supported by the setup callback function ?

Any format supported by the VLC video output. The most commonly used are, in YCbCr domain:

• I420: planar 4:2:0, order YUV
• YV12: planar 4:2:0, order YVU
• YUY2: packed 4:2:2, order YUYV
• UYVY: packed 4:2:2, order UYVY

and in RGB domain (always packed):

• RV32: 24-bits depth with 8-bits padding
• RV24: 24-bits depth (like HTML colors)
• RV16: 16-bits depth
• RV15: 15-bits depth (5 per component), 1 bit padding

Most popular video codecs output I420. Video and screen captures are usually in RGB.
