Hi, Thanks, I am working on some possible solutions now. One idea I have is to skip MediaPlayer altogheter and write some native-code that will communicate directly with Stagefright/OpenCore. However, after a quick look through their source, they seem to not allow me the freedom I want either. A possible solution would be to feed the raw h264 bytestream to the media-framework (if possible) and send the frames back up to the GUI through JNI.
Btw, do you have any or know of any examples of how to use Stagefright/ Opencore? -Kristian On Oct 27, 9:01 pm, Dana L <[email protected]> wrote: > There have been a couple of threads on this topic over the past few > weeks.
