Hi guys I'd like to start by explaining that when it comes to video codecs, colour formats and such, I do not have a clue! I am currently doing a small program that captures a single frame of video in the YUV420 format from a video recording device, and dumping it to file using the SDK provided with the device. OpenGL apparently does not support having different resolutions on its textures. 0 context to render their content. There is no documentation on it, because it is opaque. Use an OpenGL texture. The idea behind the "opaque" format is that it's whatever the device manufacturer decides is most appropriate for the device. OpenMAX includes OpenMAX AL in NDK, MediaCodec, and OMX-IL (which is not Google code, but must be implemented by the author).
