How to display opencv video in pyqt apps

The code for this tutorial is here

Opencv provides are useful, but limited, method of building a GUI. A much more complete system could be acheived using pyqt. The question is, how do we display images. There are quite a few possible routes but perhaps the easiest is to use QLabel since it has a setPixmap function. Below is some code that creates two labels. It then creates a grey pixmap and displays it one of the labels. code: staticLabel1.py

from PyQt5.QtWidgets import QWidget, QApplication, QLabel, QVBoxLayout
from PyQt5.QtGui import QPixmap, QColor
import sys

Method for animating Android fragment positions during a add/replace/remove transition using custom properties. This method does not require subclassing target views with additional setter methods, but instead requires subclassing the fragment...something you are likely already doing.
/**
* An example of adding these transitions to a Fragment. This simple
* version just applies opposite transitions to any Fragment whether it is
* entering or exiting view. You can also inspect the transit mode parameter
* (i.e. TRANSIT_FRAGMENT_OPEN, TRANSIT_FRAGMENT_CLOSE) in combination to do
* different animations for, say, adding a fragment versus popping the back stack.
*
* Transactions without an explicit transit mode set, in this example, will not
* animate. Allowing the initial fragment add, for example, to simply appear.

`classes.dex` method count helpers. Requires smali/baksmali from https://code.google.com/p/smali/ and dexdump from the build-tools in the Android SDK be on your PATH.
function dex-method-count() {
cat $1 | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'
}
function dex-method-count-by-package() {
dir=$(mktemp -d -t dex)
baksmali $1 -o $dir
for pkg in `find $dir/* -type d`; do
smali $pkg -o $pkg/classes.dex
count=$(dex-method-count $pkg/classes.dex)
name=$(echo ${pkg:(${#dir} + 1)} | tr '/' '.')
