Don't mind the mess!
We're currently in the process of migrating the Panda3D Manual to a new service. This is a temporary layout in the meantime.
Panda now supports AVI format for textures in Panda.
The movie subsystem is implemented using FFMPEG. Therefore, it supports all of the formats that FFMPEG supports. The functions to control the movie are as follows:
movie.play() movie.stop() movie.setTime(t) movie.getTime() movie.setLoopCount(n) movie.getLoopCount() movie.setPlayRate(speed) movie.getPlayRate() movie.isPlaying()
If you want to hear the movie's audio as well, you need to load it twice: once as a texture, and once as a sound file:
Then, you can synchonize the video to the audio:
From that point forward, playing the audio will cause the texture to update. This is more accurate than synchronizing the video manually.
For powers-of-two limited graphics hardware
If your graphics hardware does not support non power-of-two texture, your movie texture size would be shifted up to the next larger power of two size. For example, it you have a movie of 640 x 360 in size, the generated texture would be actually 1024 x 512. The result is a texture that contains a movie in the lower-left corner, and a black pad region to the right and upper portion of the texture.
To work around this limit, you have to display just the lower-left portion of the texture. To see a complete demonstration of this process, see the Media Player sample program.
The video texture works by decoding on a frame by frame basis and copying into the texture buffer. As such, it is inadvisable to use more than a few high res video textures at the same time.
Certain encoding formats do not work. So far, DV format has been determined incompatible with Panda.Previous Top Next
