VIDEO POST PROCESSING(9)

💖 Video Post Processing 💖

okay so you're in the Kernel API Manual, and this is the Video Post Processing(9) page — literally the VPP zone, bestie. ✨ VPP handles all the Post Processing after the Scanout from the VIU. We handle the following post processings:

• Postblend — blends the OSD1 only 💅 We exclude OSD2, VS1, VS1 and Preblend output.
• Vertical OSD Scaler — for OSD1 only; we disable the vertical scaler and use it only for interlace scanout. 🦋
• Intermediate FIFO — with default Amlogic values. 🎀

😭 What is missing 😭

no cap, this page also lists what is not here yet:

• Preblend for video overlay pre-scaling 🙈
• OSD2 support for cursor framebuffer
• Video pre-scaling before postblend
• Full Vertical/Horizontal OSD scaling to support TV overscan
• HDR conversion 🌈
