The mobile version of the media player allows you to synchronize sound and image when playing a video on a smartphone or tablet. Here is how to use this function.
Bluetooth headphones provide significant freedom but sometimes suffer from a major flaw: latency in the transmission of sound. For example, it may take more than a second between the time the sound is sent from the mobile device and the time it is delivered to your ears. This shift is not a problem for listening to music, but it is very unpleasant for watching videos because the sound and the image no longer match. If you have the VLC player for iOS or Android, luckily you can correct it:
- Start playing the video in VLC and start listening to find out whether the sound is shifted or not. If there is a lag, tap the screen to bring up the controls, then tap the button with the three little dots.

- Tap on icon with speech bubble to bring up the audio shift menu. Then tap on the button – to create a negative offset. It is then necessary to proceed by trial and error, but a delay of -1000 ms (1 s) is a good start.

- Tap somewhere else on the screen. VLC then offers to save your settings so as not to have to redo the operation the next time you use the player. Note that the computer version of VLC also has an audio shift function.
