Youtue Watch Me Android application closing unexpectedly
18 septembre 2015, par KichuI create android application from https://github.com/youtube/yt-watchme.
When I try to create the event using the "CREATE LIVE EVENT" button.It throws some following error. I think it’s happening due to the camera permission issue.

x264 library speed - Altivec vs SSE4 -
15 août 2015, par Asain KujovicI have simple cheap dualcore intel-3ghz-debian and access to super-expensive powerPc7-Aix.
And after few days of strugle, i compiled libx264 and tested it on both computers :
- GCC : library x264 on intel (with SSE2 capabilities) and
- GCC on 16 core powerPc (with altivec).
... and result is that cheap intel is x2 times faster ! (with altivec disabled, intel is 10x times faster)
My question : is this normal ?
Does all other powerPC-users have same results ? Can powerPc-altivec-optimisation of x264 library work at same speed with intel... or MMX/SSE optimisation is officially at least 2 times faster for this library ?I am not interested in multi-thread options. Number of cores and threads are irrelevant. Just simple one-thread x264 encoding with default "medium preset" using rawvideo as source, sse vs altivec.
Maybe native Aix XLC compiler provide better results ? (i managed only gcc to work)
... mac-powerpc-users maybe know something about this.

How to install JavaCV on Android and use FrameGrabber
9 octobre 2016, par MarkCould someone tell me where I’m doing wrong ? These are the steps that I have followed :
- Downloaded the adt-bundle-windows from android developer website
- Created a new project and a libs/armeabi folder
-
Extract all the *.so files from javacv-android-arm.jar, opencv-2.4.3-android-arm.zip, and ffmpeg-1.0-android-arm.zip directly into the newly created "libs/armeabi" folder, without creating any new subdirectories.
(A part that I don’t understand is "Extract all the *.so files from javacv-android-arm.jar", I simply inserted the javacv-android-arm.jar file inside libs/armeabi folder)
- Navigated to Project > Properties > Java Build Path > Libraries and click "Add JARs...".
- Selected both javacpp.jar and javacv.jar from the newly created "libs" folder.
After that I have downloaded OpenCV2.4.3 from here and ffmpeg from here and extracted the files on my C :/ root.
Finally after setting my system path...,C:\opencv\build\x64\vc10\bin;C:\ffmpeg-64\bin;C:\Program Files\Java\jdk1.7.0_10\bin...if I try to use simply FrameGrabber in my Android application...
