Some of the compression algorithms have been implemented in hardware on GPU, so for even speedier decompression the decoder can in some cases use hardware decompression, in that case, you also have a video driver involved and the driver depends on the type of video card you have installed.Īfter the decompression, we have an uncompressed image of a video frame. Typical video compression is lossy and uses similar techniques as image compression, like jpeg for each frame in the image and also the fact that not every single pixel changes between frames. There are a whole lot of different compressions out there and they are constantly being improved upon. This basically takes the video stream and reads it in compressed format and decompresses it. Then we need a video decoder for the video stream. This piece of container parsing code is also sometimes called a splitter as it is splitting up the video file into separate streams of the same data type i.e streams for audio, video, etc. How the format stores its data is dependent on the video format i.e. So the first thing we need is to read the data in the container and split it out into its different parts. A video file, i.e the container, contains video, audio, and perhaps other data.

To decode a video we first need to load and parse the video file format. So what happens when a video is indexed and what is the problem here? What happens during video indexing? But even so, we have reports of people getting crashes when they index large lists of videos.

We also code to handle broken videos, conflicting codecs, and so on.

We have put in plenty of effort to fix bugs in our software to make this as stable as possible. After each video is indexed the current playlist is saved so the program can continue where it left off in case the program crashed, the power went out, Windows decided it was the perfect time to do an update, or the program closed down for any other reason. Having videos on a fast device and having a fast multicore CPU will help but even so, if you have many videos it will take considerable time.įrom the start, we made sure you can add a list of files to index so that you can let it work along if you have hundreds or thousands of videos to index. Just reading through the large files is a time and CPU-consuming process. Indexing videos are always going to be a pretty time-consuming process since the video file needs to be read and decoded. We have worked very long to make sure Fast video cataloger indexing is stable and can handle just about all video formats.
