The video codecs are part of the operating system and therefore PTV Vissim has no influence over which codecs are available. Make sure that the desired codec(s) are installed on your computer before starting PTV Vissim.
For successful playback, you need to ensure that the codec used for recording is also installed on the computer system where it is played back.
Please note that for x264 there is a 32-bit and a 64-bit edition available. Choose the edition that complies with the application for recording/playback (e.g. x264 32-bit for PTV Vissim 32-bit). If you are unsure, you may also install both editions.
As an alternative for playback, you may use a media player with built-in codecs such as VLC media player.
(Please note that using these codecs and other software is at your own risk and is outside the scope of PTV Support.)
