Video playback frustration

vvvv beta question
1

I’ve been trying real hard to learn vvvv and I’m just in love with it. But video control and playback is really getting on my nerves. I’ve seen many threads here at the forum and so far I just got more and more confused.

Is it really that hard to control a small video in realtime? How could I accomplish:

  1. reverse playback
  2. controlling speed of playback
  3. looping
  4. playing only a portion of a video.
  5. Quicktime playback (specially H.264)

I managed to loop and to play only a portion of a video. Playing only a portion of a video was also quite easy, although I could not fully understand the “Do Seek” and “Seek Position”.

As you can see I’m overall a bit confused about how video works within vvvv. I would really appreciate if anyone could help me on this matter. Attached I’m posting the patch I’m using to experiment.

Thank a lot!

question 1 to 4 can be realized by DoSeek & SeekPosition

with DoSeek you take control over the playhead of the video. the video jumps to any position set at SeekPosition.

once using DoSeek, the Play and Loop Pin become useless. See attached patch for playing a video back and forth.

for more infos about Codecs such as H264 (which isn’t recommended in vvvv) refer to the documentation http://vvvv.org/documentation/faq-codecs
