Re: [PD] cannot get pix_record to work

I've also tried with "auto 1", with and without the bangs, and nothing changes.

Hi,

I've recently tried all the codecs but without success... :-/ (pd-ext 0.42.5 // gem 0.92.3 // Ubuntu 10.04)

Sorry...

If someone knows a way to make it works, I'll be happy too...

Cheers...

Some more detailed information of what happens:

1 I start Pd Extended
2 I open the patch which uses pix_record
3 send it "codec 5"
4 send it "open filename.mov"
5 send it "record 1"
6 send it a bang at every frame
7 send it "record 0".

(it is always receiving the gemlist)

Result: it only records the first frame (not a black frame, an
actual frame).

If I repeat steps 4-7, i records only one frame again (overwriting
the file, as expected). If I repeat only steps 5-7, it does nothing,
doesn't even touch the file (this may be expected).

If I close the patch (but not Pd), and repeat steps 2-5, it crashes.


This is Pd Extended 0.42.5, gem 0.92.3 compiled sep 22 2010 (comes
with pd extended), Ubuntu 10.04


Apart from the crash which I can avoid, is there something I am
missing to have it record more than one frame??? Does anybody know
of a codec that gives less issues? (there are too many to try them all).

thanks

    Hi,

    Time ago I succesfully used pix_record in Windows by trying
    different
    codecs until I found one that wouldn't make it crash.

    Now I'm trying to use it in linux and I managed to create the output
    file and it seems it records one black frame, but nothing more.
    The file
    seems to have the correct dimensions in pixels but it never grows to
    more than a few Kb.

    I use "codec 5" which is ffmpeg mjpeg.

    I have:

    [gemhead 99]
    |
    [t b a]
    | /
    [pix_snap 500 500]
    |
    [t b a]
    | /
    [pix_record]

    Well I'm simplifying it, because I have a spigot so that the
    situation
    is equivalent to the picture above only after I've sent the
    "record 1"
    message.

    I send to pix_record, in this order:
    "file output.mov"
    "record 1"
    ... now for every frame I send it a bang (and the gemlist of course)
    "record 0"
    ...now i stop banging it

    I've verified that pix_snap is snapping as expected (I've tried
    putting
    a pix texture after it and using the texture on a square).

    Any idea?

    It prints this message to the console when it receives the
    "file" message:
    encoding as Quicktime (QT7 compatible)

    but it doesn't print any message when it gets the "record 1" and
    "record
    0" messages.

    thanks
    m.
