Sometimes you can only hear the sound in the MP4 video without any picture. Besides, there are also other troubles you are in apart from this. Are you aware of them? What is causing the MP4 video not run on the media player? If you are facing the problems, in this article, more detailed information will be introduced and please be patience to read through the whole article .

Part 1: Possible Reasons for MP4 No Video Problem

Sometimes, when we are struggling to download videos from the Internet or copy them from other places, once we put them on our computer, they will not play properly. Many people think that it is a problem with the computer, and it is recommended to upgrade the computer system. What is the specific reason? For the detailed information, the possible reasons are described below.

Damaged MP4 files

The reasons for MP4 file corruption are: The storage medium such as memory card when recording MP4 video is full; Camera or device error while recording video; Interruption when moving MP4 files from one storage drive to another; MP4 header file is damaged due to unknown error; CRC error or interruption during MP4 video file download; Virus infection or storage drive contains bad sectors of MP4 video; Changing the file format of MP4 video files, from one format to another also causes MP4 movie damage. If possible, you had better download the MP4 video from the Internet one more time.

Hardware acceleration

Sometimes we play video only with sound, but the screen is green. This dynamic problem is not caused by the unreasonable design of the driver. It is caused by the player and the incompatibility with your driver. The solution is very simple. You can just open any video website, right-click the settings after playing, and remove the hook before enabling hardware acceleration. Generally speaking, enable the hardware acceleration on your computer can speed up the running of the media player, however sometimes it can block the MP4 video to be read completely by the media player. In such a case, you had better turn off the hardware acceleration function.

Lack of MP4 codec

In most cases, when we open MP4 videos, we use the video player that comes with the system, and because the system's built-in player is not capable of encoding and decoding, it appears or not when playing some videos. The reason can be that there is no sound on the screen or the screen cannot be opened at all. Even if the video is of the same format, it will not be played properly because the video encoding is not supported. Specifically, if you try to play the MP4 video on Windows Media Player, but the MP4 codec has not been implemented into this media player, then it may result in the MP4 playback failure on the player.

Part 2: Download and Install MP4 Codec

Instead of downloading a specific MP4 codec, you can turn to K-Lite Codec Pack which has already contained all the audio and video codecs needed for various multimedia files. By downloading and installing the K-Lite Codec Pack, you wouldn’t be able to install any other further codecs anymore in the future. Therefore, I will recommend you to download the codec pack as your firm solution.

Step 1. Go to K-Lite Codec Pack website and find the download option. Then click the download button to start downloading the codec pack which is usually in WAR format.

Step 2. Unzip the K-Lite Codec Pack WAR file and click the install icon in the file to start installing the file step by step. You had better select the “Easy Installation” mode which is much more convenient and simple.

Step 3. Restart your media player and load the MP4 file to the player again to make it work properly.
