Why would I want a YV12 codec?

Well, you might not want one. This codec probably won't be all that useful to anyone who isn't involved in developing image processing or codec (compression/decompression) software. YV12 is a planar Y'CbCr 4:2:0 image format, and is often used as an intermediate format by reference codecs such as the ISO/IEC MPEG-4 video decoder reference code. It's not a very good choice for end users, because it doesn't really compress video that much, and it stores pixel data in a manner that's not particularly convenient for playback.

That said, you might find this codec useful if you're a developer working in image processing. As mentioned above, YV12 is a planar format, meaning that for each image, the luma data for all pixels is stored consecutively, followed by the chroma data — this method of accessing pixel components is convenient for many image processing techniques.
