video streaming - RTSP gstreamer pipepline to Android VideoView -

-

i'm trying construct gstreamer pipeline on panda rtsp video+audio android 4.1.2 app. android app uses:

videoview.setvideourl(uri.parse(":rtsp://..."))

to view video. on panda i've built gstreamer-0.10 (to working uvch264_src element take h.264 video logitech c920 camera) , using gst-rtsp-server/exmaples/test-launch serve video+audio via:

./test-launch 'uvch264_src do-timestamp=true mode=2 post-previews=false usage-type=1 iframe-period=2000 peak-bitrate=400000 rate-control=qp auto-start=true name=src ! queue ! video/x-h264,width=640,height=480,framerate=30/1,profile=constrained-baseline ! h264parse ! rtph264pay name=pay0 pt=96 \ alsasrc do-timestamp=true device=plughw:2,0 ! audio/x-raw-int,rate=44100 ! queue ! audioconvert ! ffenc_ac3 ! rtpac3pay name=pay1 pt=97'

i can view stream on vlc (audio isn't in sync), android tablet fails play stream. if remove audio portion of pipeline:

./test-launch 'uvch264_src do-timestamp=true mode=2 post-previews=false usage-type=1 iframe-period=2000 peak-bitrate=400000 rate-control=qp auto-start=true name=src ! queue ! video/x-h264,width=640,height=480,framerate=30/1,profile=constrained-baseline ! h264parse ! rtph264pay name=pay0 pt=96'

then android app has no problem playing it.

how can encode audio+video pipeline such videoview can play it? need mux audio , video mpeg-ts stream first?

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
