self.myMovieTexture=MovieTexture(“myavi”)
assert self.myMovieTexture.read(avipath), “Failed to load video!”
in panda171,it is ok
in oanda180, self.myMovieTexture.read(avipath) got some err
Thank you for the report! Do you have a link to the failed avi file so I can try it out too?
Thanks!
David
What operating system are you using? What is the error message? Does it play in spite of the error message, or does it fail to play completely? When did you download Panda3D 1.8.0?
Thanks.
David

I can’t reproduce the !scale.is_nan() error, so I don’t know how that happened. There was a temporary bug in a much older build of 1.8.0 that would have allowed that error, but it has been fixed for a long time.
However, I did find a bug in MovieTexture.getTime() that was returning the wrong value, which was causing your program to terminate the movie early. I’ve committed this fix, and it should be available in the next buildbot release.

Well, are you sure the filename is correct?
David
the filename is correct
I use panda170 to run the demo ,it is ok
Oh, wait. You’re seeing “MovieVideo::open error 1”? This means that you didn’t build Panda with ffmpeg support. (HAVE_FFMPEG wasn’t defined.)
Did you build your own Panda? Did you provide a working ffmpeg library? It doesn’t seem that makepanda located ffmpeg. When you run makepanda, look for a message like this at the start:
WARNING: Could not locate thirdparty package ffmpeg, excluding from buildDavid
Thanks!
I download ffmpeg library,and it is ok now.
Is there a download link to all the thirdparty?
This is available on the 1.7.2 SDK download page. There’s not yet one provided for the 1.8.0 build, though, but the 1.7.2 version should be close enough.
