I think you have the wrong subforum.
I'm guessing you're asking if there is a shader that can play a video as a texture. I think you're looking for this:
6.1.3 AnimMap <frequency> <texture1> ... <texture8>
The surfaces in the game can be animated by displaying a sequence of 1 to 8 frames (separate texture maps). These animations are affected by other keyword effects in the same and later shader stages.
<Frequency>: the number of times that the animation cycle will repeat within a one second time period. The larger the value, the more repeats within a second. Animations that should last for more than a second need to be expressed as decimal values.
<texture1> ... <texture8>: the texturepath/texture name for each animation frame must be explicitly listed. Up to eight frames (eight separate .tga files) can be used to make an animated sequence. Each frame is displayed for an equal subdivision of the frequency value.
Example: AnimMap 0.25 animMap 10 textures/sfx/b_flame1.tga textures/sfx/b_flame2.tga textures/sfx/b_flame3.tga textures/sfx/b_flame4.tga would be a 4 frame animated sequence, calling each frame in sequence over a cycle length of 4 seconds. Each frame would be displayed for 1 seconds before the next one is displayed. The cycle repeats after the last frame in sequence is shown.
Design Notes: To make a texture image appear for an unequal (longer) amount of time (compared to other frames), repeat that frame more than once in the sequence.
