- Frequently Asked Questions
- ==========================
- What is libmegapixels?
- This is a library for accessing V4L2 cameras on modern ARM platforms that
- use the media-request pipeline to do routing of cameras to the SoC hardware
- to process the pixels in various ways. It's intended to be called instead of
- opening the plain V4L2 device so it can configure the hardware to a specific
- mode and then it hands over the V4L2 handles to let your application do the
- normal Linux camera procedures.
- What is the correct way to display the name 'libmegapixels'?
- Just follow the correct grammar rules for your language. Being difficult
- about the capitalisation of project names is just a massive waste of time.
- How is libmegapixels different from using V4L2
- Libmegapixels is just a glue layer on top of V4L2 to make writing
- applications that use the new media request pipeline a lot easier. Once the
- pipeline has been configured libmegapixels will just hand over a file
- descriptor for a regular V4L2 device to get the frames from.
- Does this mean the camera stack is completely open?
- Yes, libmegapixels does not support the Android mess that is closed-source
- userspace sensor drivers and also provides an open source AAA algorithm.
- Using closed modules in libmegapixels is prohibited, but it's only a
- library for accessing V4L2 so whatever happens in the applications is up to
- the applications.
