Support for h264 mpeg4 ?

[Luis Linietsky]

Thanks Sebastian,
I have been reading some more on docs.gstreamer.

I added "ffmpeg" to the build script, as follows:

GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) ffmpeg

and when I try to build the Tutorial5 project, I'm getting following error:

I also try building  hlsdemux, but I got the following output:

Am I missing something ?
Thanks !

Please read the documentation at

Especially at the Android.mk part. That's what you need to do to link additional plugins.


For h264 and mpeg4 you will either need to ffmpeg plugin, or the androidmedia plugin
(which only works on JellyBean and newer but uses the system/hardware codecs).

Use the hlsdemux plugin, encryption is not supported yet though.
