Abstract: At present, Windows system was used to design the player for most of the railway passenger cars. But the Windows system is vulnerable to viruses and can easily cause a crash when a passenger car is often powered off and reset. In order to solve these problems, this article proposed the construction of the player using GStreamer framework based on the Linux system, gave the system running effect diagram. The verification results showed that the audio and video player got clear and stable playback effect with short development cycle and strong practicability under the GStreamer framework.
