No it hasn't. It plays .mp4 videos fine here, on several systems.
I am using a Thinkpad T530 with Intel graphics. I tried all the
different video output modes, and none of them work. I also tried
disabling hardware acceleration, but that did not help either.
Did you disable it completely in VLC's ? Did you choose a different
output device than "Auto" or "VDPAU" as well when you disabled it?
This seems to be a common problem:

I don't see this as a "common problem" with VLC.
_3_ people have mentioned a problem in this thread, and for two of
them it is solved meanwhile.
Here is the output when I try to play an .mp4:

======================
Well, your problem is definitely related to hardware decoding (not VLC
itself).
Please follow the last post in the thread. Or are you the same person
anyway?
To repeat here:
As you have an intel system, make sure you do not have vdpau-video
installed (although according to your output this seems not to be the
problem, as libva opens /usr/lib64/dri/i965_drv_video.so).
So I would suggest you try to uninstall libvdpau_va_gl1. This redirects
VDPAU to VA-API (libva), so that you can use VDPAU on intel systems as
well.
As VLC supports VA-API directly anyway, this is not really necessary.
Kind Regards,
Wolfgang
