do you think it's possible to recording what's happen in a jit.pwindow and make a automatic import of this video to be read in the same window?

Hello,
do you think it's possible to recording what's happen in a jit.pwindow and make a automatic import of this video to be read in the same window?
thanks

it's possible. but you have to be careful with your timing of messages.

you need to use the successful "write" notification that comes out the dumpout of qt.record to trigger the read message.

that's ok, with you're indications I just put a delay, and it's works fine.

Hello Robert,

Thank you!


i would strongly encourage you to not do it this way. what happens if it's a very long video and there's a lag in the hard drive and it takes more than 1 sec to write to disk?

see if this patch helps explain how to use the write notification:

So, I didn't try with long video, because I want to use it just for few secondes, to record a movement and immediatly play in reverse.

In my patch the video fps is 50 on the first,24 on the second window , which is not the case in you're patch, they are 2 at 50.

second the size of mine is really bigger than yours, my eye don't see the difference of the quality, the flow is 70 mbits/sec for mine and 11mbits/sec for yours, may be it's the jpeg codec...

For 1 minute I see a little fastly apparition in the second window in you're patch, slower in mine,

I am new to jitter, and I tried to understand the process, not so easy!

the message write passes on route object, unpack is here to receive write or not write message ?

why put a gate, if the message write passed in route and unpack?

Prepend and deferlow serve to put the priority of the not write message in front of priority of the write message? In order to not pass the write message before the video is recorded?

So if you’re agree to explain me that, it’s ok, but I really can understand it could be boring, and I will continue to pell and discover jitter!!

all of that for 10 secondes

so I approve you're way is better!

I have questions:

the message write passes on route object, unpack is here to receive write or not write message ?
what are “s” and ”i “
why put a gate, if the message write passed in route and unpack?
Prepend and deferlow serve to put the priority of the not write message in front of priority of the write message? In order to not pass the write message before the video is recorded?
It’s difficult for me to understand!

In any case you give me the solution,
Thank you!
