What software did you use to watch the surveillance video of the community? I asked about the property, but I don't know what brand of monitoring software it is. Video is in MPEG4-4 file format.

-

MPEG4-4 is a video compression standard in China. The compressed video effect is basically the same as DVD, but the size is similar to the traditional MPEG 1 format. In this way, we can accommodate the next DVD-like movie on two CDs. At present, three movie FTP servers have been established, most of which are compressed movies in MPEG4-4 format, and the extension is AVI.

Although the effect of MPEG4-4 movies is good, it also has some disadvantages, that is, a lot of software must be installed to play, and even if installed, some machines will not be able to play because of such problems. The most common faults are that the picture is silent, or the picture is silent, and so on. In addition, playing movies in MPEG4-4 format requires a higher machine. If your machine is slow, or the software is too complicated, the effect may not be ideal. Next, I will specifically introduce how to install the software to play MPEG4-4.

Name description

Windows Media Player 7.1Microsoft Media Player 7.1,which is the tool we use to play movies in AVI, ASF and WMV formats.

Windows Media Player 8 is installed on Windows2000, but Windows98 cannot be used. The function is basically the same as version 7. 1, which takes up more resources.

DirectX 8.0 must be installed. However, it is said that DirectX 8. 1 will have problems and has not been tested.

DivX 4. 12 must be installed. Core plug-in

You need some AVI files of AC3 filter, otherwise there will be no sound, so you'd better install them. If it is installed under Win98, please execute the registerfilters-98.bat file; If it is installed under Win2000, please execute the registerfilters-win2000.cmd file.

Subtitle processing is like playing a DVD. Users can choose whether to play subtitles and in which language. It is recommended to install vobsub2.05 or above.

MicroDVD can replace the software of Windows Media Player to play MPEG4 files.

Installation sequence:

DivX 4. 12->； AC3 filter->; DirectX 8.0-& gt； VobSub 2.0X-& gt； Media player 7. 1

According to the above instructions, generally speaking, you can play files such as AVI.

After it can be played, let's see how to add subtitle files.

When watching VCD before, we found that subtitles are a part of the image, and we can only watch whatever subtitles we give. But it's different on DVD. In DVD, dubbing and subtitles are optional. For example, we can choose to play an audio track of a certain language when playing, so that that is the pronunciation of that language; So do subtitles. We can choose subtitles in different languages.

We can choose to play subtitles in different languages. This requires the support of VobSub software.

Installing VobSub is very simple, and it can be used without configuration after installation, so I won't talk about it here.

A subtitle file is an independent file, usually called *. Sub or *. Srt, etc. If you have these files, then you can load subtitles. Without this file, generally speaking, there are no subtitles when playing. Take *. Take srt as an example. If the subtitles are in srt format, it is very simple. Just put it in the same directory as *. Avi file and start the player.

If it's a subtitle of *. Sub, it will be more troublesome. Subtitles are usually 1 or 3 files added together. If there are three files, then there are also *. Idx and *. Ifo file. Note: Users must change *. The avi file is saved with the same name as *. ifo，*。 Idx and *. Subfile. Remember!

So you can subtitle.

When playing, you will find a green arrow icon in the small icon in the lower right corner of the screen, which is the icon of VobSub. You can choose the language and other information to play in it. Very convenient.

If you really can't fit the subtitles, the most common situation is that there is only sound and the screen is black, so just delete all the files except *. Avi in the movie catalog. This shows that there is something wrong with your VobSub. And this kind of problem is very common, please check your installation steps patiently.
