I've mostly tried .mov or .mp4 files; as far as I can see, they all use H.264
I can't explain why this happens.
I'm running the patch on OS X 10.9.4

Hello,

I've built a very simple video player in pd using GEM. Just the standard player with a gemwin object and the gemhead pix_film pic_texture chain. The movies play, but at the wrong speed. I've just exported a movie from my video editor with 24 frames per second. I know the the default argument in the gemwin object is 20, but whatever number I give as an argument, it never matches the actual speed of the video.
I have an auto $1 message as an input the the left input of pix_film, so everything should work, at least according to several tutorials I have consulted, but actually films play more or less at double speed (or more) when I just try to play them by toggling auto $1.
What am I doing wrong?

Thanks a lot!
