Implement video player with PYSIDE/PYQT and use Pyinstaller to pack and publish

The first time with Pyqt/pyside, encountered a lot of problems. All the problems encountered in the video release this piece encountered, but finally succeeded, here to summarize the problems encountered.

Read the frame in the video, show it by frame, the format must be qimage, but the format of the frame read with CV2 is NumPy array, it must be converted to Qimage, so try:

1. Using pyqtgraph:

The NumPy type of frame through pyqtgraph conversion to qimage, and then through the Setpixmap display, the program in idle execution is correct, but in the release, encountered a lot of disgusting problems, because it is to help others do, I do not have so much time to solve the problem, Then a second approach was adopted.

                Frame,stat=pyqtgraph.makeargb (frame, lut=none, Levels=none, Scale=none, usergba=true)
                frame= Pyqtgraph.makeqimage (frame, alpha=none, Copy=true, Transpose=false) #
                
                Frame=qpixmap.fromimage (frame)
                Self.pictureLabel.setPixmap (frame)

2. Use PiL to save the image, and then read it through Qimage, and convert it to qimage format directly:

But with the new problems encountered, through the CV2. Videocapture ("001.avi") read the video file, through the conversion below, the color channel incredibly chaotic, I tried to use Numpy.roll () will channel flip, but the effect is not ideal, and slowed down the speed, really helpless ~, so there is a third way to try

                Frame=image.fromarray (frame)
                frame.save (' 2.jpg ') 
                self.image.load ("2.jpg")
                Self.pictureLabel.setPixmap (Qpixmap.fromimage (self.image))

3. Use Cv2.cv.fromarray () to convert the read NumPy frame, then save and then read ~

This success, through the Pyinstaller packaging after finally can be displayed normally.

                Frame=cv2.cv.fromarray (frame)
                cv2.cv.SaveImage (' 2.jpg ', frame)
                self.image.load ("2.jpg")
                Self.pictureLabel.setPixmap (Qpixmap.fromimage (self.image))

The above three methods do not have errors in idle, that is, when packaging the release encountered an error. And when it comes to containing pyqtgraph libraries, there are a lot of difficulties in packaging the release process, which eventually forced me to abandon the use of pyqtgraph.

In the use of Pyinstaller packaging, but also encountered some problems, this article is using the Pyinstaller 2.1 version.

First CD into Pyinstaller, Python setup.py install, then execute Python pyinstaller-f-W yourpy.py (-F is packaged as a file,-W is Windows edition, no small black window).

It is recommended that you perform a Python setup.py install before each package (so you will avoid a lot of trouble)

Put a picture on the background of the video window, set the background, if he did not show, in C:\Python27\Lib\site-packages\PyQt4\plugins find imageformats this folder, and EXE put in a piece, on the line, All right, paste the program:

The program has three buttons, each button press down, will play two consecutive videos, and then click Will pause. The final interface is as follows:
