'constrained-baseline' is an alternative profile name, and
'gst_amc_avc_profile_from_string' not recognize it, which made
create_amc_format return -1 with the warning "Unsupported profile
'constrained-baseline'".

"Profile" is not used currently, so try to comment out related
branches in create_amc_format.


Also, you may try this:
http://dev.lemote.com/files/upload/software/rtsp-demo/mcplayer.tar.bz2 [1]

And modifies the pipelines in mcplayer/src/com/lemote/mcplayer/MCPlayer.java.

e.g.
Try "hw encoding test", this will encode videotestsrc output and send
to an udp addr.
If you can see data sent on the net, the encoder is probably working.

Then you can run a receiver on an other machine(Note: take care of
firewalls), the pipeline will be:
gst-launch-1.0 -v udpsrc uri=udp://0.0.0.0:3057
caps='application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96,sprop-parameter-sets=(string)\"J0LgH41oBQBbpsgAAAMACAAAAwBAeKEVAA\\=\\=\\,KM4ESSA\\=\"'
! rtpjitterbuffer latency=10 ! rtph264depay ! avdec_h264 ! videoscale
! autovideosink


[1] Building instructions.
1. cd /path/to/mcplayer
2. android update project -t TARGET -p . # Get TARGET from 'android list'
3. ndk-build && ant debug
