May be add a separate egl_context parameters to configure texture decoding and
texture encoding separately (which should be the same if both encode and decode
to texture is enabled)?

Done. Added a new method
PeerConnectionFactory_nativeSetVideoHwAccelerationOptions2 (2) since the jni
compiler does not like to functions with the same name.
