DV Firewire input plugin understand, requested, problems, created

andy

I know that this is a bit of a strange request, but is there a plugin, or could a plugin be created that can access a DV Firewire connection.

I understand that this connection is not seekable as most plugins desire, but it could be made so that whenever you requested any frame, the current frame would be returned.

This would allow me to put up a live image from my camera with avisynth filters working on them.  Of course problems would occur if I tried to encode the video using this type of plugin, but that is not my intention.  I simply want to live showing of video with avisynth filters altering it first.

I do not even know if this is possible, but thanks in advance, HighInBC

I use this little program to output an AVS via firewire to my DVCam with a TV monitor plugged in. I just drag n drop the avs and can see the results on the TV. Perhaps it is what you are looking for?

that is the opisite of what I wanted, I wanted the DV output too the avs input plugin...

I supose I was a little unclear... but hey that program sounds very usefull as I do export avs files to DV tape frequently.

Thanks

I was just looking for exactly the same thing a few days before (see this thread), and it doesn't seem like this is possible at the moment.
LigH elaborated a bit more on the topic in the German  forum: it comes down to avs requesting a lot of information before opening a stream, like frame size and rate, video format and number of frames - and the latter cannot be provided ...

Sasly enough, there seems to be no way to open live streams in avs at the moment. Please let me know if you come up with a solution ...

with kind regards,
Thoralf.

looks like this is one for avisynth 3.0

as far as opening live streams goes... doesn't TCPsource do something like that?  or does it also get the other information?

this would be another killer feature :-)

Shodan closed the thread ... however, my problem is to get a livestream opened by avs. As far as I understood, tcpsource broadcasts video streams over a tcp/ip network, which is quite fine - but the stream still needs to be opened in the first place.

AviSynth isn't designed for realtime streams, and IMO it belongs in dedicated apps, as Dscaler.

ffdshow is capable of streaming live material through AviSynth. It does however ignore the framenumber when AviSynth requests a given frame, and always return the current frame.

does there exists any manual how to setup avisynth using ffdshow?

I tried that, but without success.

would temporal filtering work with ffdshow, cause it is always returning the SAME framenumber ?!?

Simply use the quot;AviSynthquot;-tab in the settings to insert your filters. Works very nice in my experience - I use it for postprocessing instead of the internal filters.

Temporal filters do work - however the results cannot be relied upon. Temporalsoften works nicely for instance, same does MipSmooth in my experience.

Just take your script right click and say open with what ever media player you want and it will on the fly play but lagging so u need a good pc or use ffdshow.
