Can videos played using media_play or media_loop be played backward?

I have tried to do this with media_tune by setting the "rate" parameter to -100. The video will mostly play forward, but will jerk into reverse for a very short blip every few seconds.

Any suggestions?

Thanks

I believe it's impossible but it's possible to flip the video with a rendering too l (adobe primiere).
If it's just one file pm me a download-link of the movie and I'll do this for you...

Thanks for the offer. Actually I need to be able to play the video forward or backward depending on real-time conditions.

To clarify the question, does the engine allow controlling the video this way (forward then backward) with media_tune?

Thanks

i don't know if the media commands of the engine allow it but for sure this also depends on the used video codec.

most codecs don't encode every frame as full image but only the differences to the previous frame(s) so smooth backward playback is tricky. i think you would have to use a codec which encodes every frame as full image like motion jpeg or dv (which actually is motion jpeg too).

Thanks for responding Ventilator.

The videos in question are actually AVI files. Is there a codec involved in playing an AVI file?

Thanks.

you can probably look for some c++ video playing libraries, and make a dll, but that might be a bit more difficult than the worth, if you do it tho, i'd put a few more features into the dll and sell it as a plugin, im sure it'd sell to some people.

I don't think that videos can be easily played in reverse - codecs usually only store the difference of the current frame to the previous one.

Thanks all.

These are all good answers.
