I realise you've probably solved this, but here's a patch explaining how to do this as clear as I could make it. But remember, in PD, there's always a better, more graceful way to something !

To be honest, I don't know how to do that. As for me, I prefer to convert videos with all audio tracks. The best tool that I have used is M4V Converter for Mac. It is designed for all iTunes users. If you have purchased or rented movies/TV shows from iTunes store, you may knew all iTunes videos are encrypted with fairplay DRM protection, it can be played on Apple devices only. There is no right for you to re-encode or share it to other devices, even you have paid for it. Fortunately, now it is much easier for you to use such a DRM removal tool to crack DRM protection and convert videos from M4V to MP4 with lossless quality. You can catch more info about it on HERE. Wish this tip is helpful to you. Good luck.

@Mikssa Pure Data does not play video with sound. It uses "Gem" to play only the video. It can be made, with some difficulty, to play them together, but that is not really useful.
The audio has to be split out from a video, and then re-synchronised from the two discreet sources. To do that any compression has to be removed, so a tool like http://www.squared5.com/ is most useful.

The playing of the video (in an acceptable format) can be done with Gem, or any other program, controlled by a Pure Data patch directly for Gem, or through network messages or system shortcuts for other programs.
Pure data users are not usually interested in the original soundtrack, preferring to make their own and sync to a manipulated video, or far more often to control a generated sequence of images. Sometimes they use the image to generate the audio.
Their work is always interesting..... and sometimes they produce art.....

Some video and audio has special codec. If there is no sound, that is most likely that the audio codec can't be decoded.
Normally I will try a video converter to convert the file to another compatible file.
You can take a look from this link here if you want to get some media converters.

@caddiesytgvwo Pure Data does not play video with sound. It uses "Gem" to play only the video.
It doesn't matter what the format is, Gem has no sound outputs.
The sound needs to be separated from the video with something like http://www.squared5.com/ (probably still the most comprehensive free converter) and then Pd can sync an audio player by reading the audio into a table and controlling the Gem frame-rate like this..... av-sync.pd
There are limitations to the length of the audio file that can be loaded into ram and played (90sec) in 32-bit Pd, that can be overcome with some difficulty......but that is another subject.
