Hello, The following patchset adds basic MediaCodec support to libavcodec, ie: only h264 is supported and the HWAccel part (Surface output) is missing.
JNI comes as a dependency. The JNI support is based on the same patchset I've sent some time ago with some improvements. I originally developed the patch against the Ndk API (Android >= 5.0) but then changed my mind and go with the JNI version for two main reasons: * there are still too many android 4 devices * there is still needs for some jni bits as the MediaCodec Ndk API does not provide a way to known the codec name which is mandatory to workaround or blacklist some implementations (ie: do not use known software decoders, workaround OMX.SEC.avc.dec as it returns invalid stride and slice-height values, ...) I decided to mimic the Ndk API minus a few differences (see mediacodec_wrapper.h) so it can be ported more easily to the C API in the future. The other reason being it is to totally hide the JNI code. The HWAccel part is on my todo list but I wanted a real use case to develop the API against. The development branch can be found here: https://github.com/mbouron/FFmpeg/tree/feature/mediacodec-support --enable-jni and --enable-mediacodec is required to build the h264_mediacodec decoder. av_jni_register_java_vm(vm) must called before lavc is used. The patchset also includes supports for Android content uris which is not mandatory for the mediacodec supports but helps dealing with them more seamlessly. In order to use this support, av_jni_register_application_context(env, context) must be called before lavf/lavu is used.
