You can use MediaCodecList to enumerate the available codecs. If it comes back with any it should indicate that you're on a device that has Android's codec abstraction present, namely /system/etc/media_codec.xml. This will list both hardware and software codecs, but none of GStreamer's codecs. > > Michi. > > > > > [1] https://requests.ci-train.ubuntu.com/#/ticket/763 > > > > Hope this helps, > > Michael > [1] http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/wily/gst-plugins-bad1.0/wily/view/head:/sys/androidmedia/gstamchybris.c#L1014 I think this will help accomplish specifically what you're looking for.
