Why is there no image but sound or no sound but image for video playback? Which codec is needed for a certain video file playback to work properly? These must be the problems you have encountered before. With VideoInspector, you can find out the video’s audio and video codecs and solve the video playback problems by downloading the appropriate codecs in real time.
Once VideoInspector is running, you first need to open the video file you want to process by using the “File→Load” menu command or the Ctrl+O key combination (you can also load it by using the “File Info” box under the “Browse” button under the “File Info” box to load the file). In the default Open File dialog box, you can see that the supported video formats are the common AVI, MPEG, Quicktime, Matroska and other four formats (Figure 1).
Once the file is loaded, the software automatically analyzes the validity and completeness of the movie and gives parameters for the length of playback. The “Video” column gives information about the video resolution, frame rate, video codec, etc. The “Audio” column gives the number of channels, sample rate, bit rate, audio encoder and other information. On the right side, it will also show whether the audio/video encoder is installed or not. If it is not installed, click the “Download” button to download and install it. If video or audio is missing during playback, choose to download the video codec or audio codec in question to solve the problem (Figure 2).
