Hello, apparently its pretty cool these days from what ive read. Im wondering if its possible to datamosh in pd if possible in real time, from what ive read its fairly simple (just playing with i frames and p frames) but i dont know how to do this in pd.
Thanks in advance.

yeah i'm with you on this, i've used some of the share-wared dedicated to this but i would love to bring it into PD.

the closet i've got is messing around with a [pic_motionblur] witch outlets to the first inlet of a [pix_compare] and via a [pix_delay] into the second inlet of the [pix_compare]

Sadly "Just playing with the p-frames and i-frames" is not something that a lot of AV IDEs allow you to do. In order to do this, you've really got to get inside the file before it is decoded, and most stuff deals with the video stream post-codec. Gridflow *might* have an answer? Pinkelephants way seems like it would approximate the effect, as would using "visual flow" to distort an image.

P.S. What shareware is dedicated to this?

I don't think it's possible to do datamoshing in Pure Data. You can get the binary data of a file but to then strip out only the I and P frames would be difficult. Plus, objects like [binfile] would be slow to do it real time. Still, it's worth a shot

There is a jpg glitch external for Pd https://github.com/badgeek/fux_videoglitch

Also, someone (sver3) got glitchy results from Pd but I think this relates to his graphics card
