How to modify the video output function of mobile phone?

This depends on whether the chip of your mobile phone has a video output function. If so, you can just solve the line transfer problem. If not, although it is theoretically possible, no one will do it. Yes, just like last time a friend asked me if I wanted to use MP3 to power a small light bulb. It is theoretically possible, but in practice it is meaningless.

Many domestic mobile phones now have this function. Well, last year a friend of mine bought a Desai M888 mobile phone, which has this function, and costs a few hundred yuan. In addition, a USB flash drive player (some are called TV companion or hard disk player) can also directly play in the computer. It costs one to two hundred yuan to play the downloaded video on the TV.

The video output is connected to the TV through an AV cable. When buying a digital camera, it is usually equipped with an AV cable. Both ends of the AV cable There should be two ports, one is the red audio output/input, and the other white one should be the video output/input. If the digital camera does not have a recording function, the audio output line will be dispensed with.
