I have found the file media_profiles.xml in my /etc/ folder (among
attachments.  Is it the same of /etc/media_codecs.xml?

In row 31 of the file I read:

  <!ATTLIST Video codec (h264|h263|m4v) #REQUIRED>

so I thought that gst element would be amcviddec-m4v for mpeg decoder. I
have tried it but element is not found by the app.

decodebin2 seems to work(but I cannot be sure that it's using android media
codec.

How can I see if it is present on my Android device? Which file should be
written for gst-omx? I have found related documentation only for specific
devices but not for Android devices.

Thanks in advance,
