Is it a limitation using videoloopback ? no. v4l2loopback does not know nor care about frames or formats. it simply passes the frames from one application to another. there is no colorspace-conversion of resampling or the like involved. OK. it's gstreamer that doesn't set the framerate correctly. you could force it by running: $ echo @60 | sudo tee /sys/devices/virtual/video4linux/video1/format in practice i don't think that this framerate setting will do much. Yes, it doesn't change anything. For info, i get 60 fps when I use the application streamViewer. how do you know? It is written in the top window border : Acquisition [ cptured: 2854, skipped: 1, fps : 61.40 ] Seeing the video capture in the Gem window, i guess it is at 60 fps. So, in this case, information about framerate return by : $ v4l2-ctl --all -d /dev/video1 or $ cat /sys/devices/virtual/video4linux/video1/format is incorrect. Thank you for your help IOhannes, now I can get the stream from a XIMEA camera in Gem. Do you think, it will be much better/faster/stable to get a v4l2 driver from XIMEA than to use a pipe with gstreamer/v4l2loopback ? ++ Jack fdsmard IOhannes ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSFzakAAoJEOuluecjw8GUxh8H/3uYQ0ZG0on0w8h1J6Rox2Tr kiIt4tSeV3fBPJfaBugYky6e003MprM8aLSyEE2ugbDMQ2tGX7O3qtau1jqpuRd6 gSA7l5R4UVK+whIunilwmG+mrBytwVUi4lx9CRmaRIgcN6GNYJO9mIDMKgOwNO7S B86SOYGX7TtKr7vTyC+z9jIq/fDaKgNQTN85gyYgimqdtP/zt1rIhkoomDuQO5u1 9IpezxPxu7JnEWqSjLJ+1VPM69k6JNsOga5A9Vv6IKvHbgWiK42n+Zr2KE4+HxlZ ZEAPJNNQg/sWH+/fAd+84tsQpAxUEr5bgTpw3ROt+wBumwk2S8wZzVZDA1BZ9rE= =1w9V -END PGP SIGNATURE- ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] outlet_float crashes on windows
Hi,
trying to compile an external for Windows XP I get a very strange
error: pd crashes when calling outlet_float on an external outlet
(even if it isn't connected). The very same code runs well on both OSX
and Linux (same pd version, but has been running there for several
years). Bypassing the outlet_floats by sending to dedicated receivers
in the patch makes everything work as expected without any problems
(which makes it even stranger as it is a pretty involved external with
internal dynamic loading and connection of abstractions communicating
with internal in- and outlets with proxies using outlet_float and such
internally without any issues).
This is my first attempt with supporting Windows and my setup might be
screwed up, so I thought I'd ask on the list whether someone has an
idea how to further investigate into the problem. I'm compiling on a
virtual machine with XP and latest MinGW. I'm linking against a pd.dll
of pd-0.43-44 using all header files from that version as well. The
test is done with a pd of the same version.
Unfortunately I don't know anything about getting a debugger to work
on Windows. (I remember it was already painful to get it working with
inspection and breakpoints on my linux machine).
Below are the relevant code snippets of the external.
Any ideas?

[PD] Pd Extended zip file from downloads page, network install issues
Dear List, The technology department at the learning institution I work at have agreed to install Pd Extended. They used the zip file (not the install) on puredata.info to do a network install (not something I know very much about). Pd Extended loads and runs core audio functionality fine but libraries appear to be missing, no GEM objects I tested work, neither does [cup] Does anyone know if there is a way to get a network install of Pd Extended to load all the libraries automatically?

[PD] Pd to Raspberry Pi SPI
Background: I'm very well versed in Max, but still a newbie in Pd. I'm working on a project to that will use Pd running on a Raspberry Pi, and that will generate control voltages using DACs (ideally something like a MCP4922 or similar, http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en020399 ). I know about Miller's gpio external, found here: http://crca.ucsd.edu/~msp/syllabi/206.13w/index.htm , but it does not do any of the SPI interfacing, which is the way that will need to interface with the DACs. Is there any possibility (Miller or anyone smarter than I am on this stuff) to extend the gpio external to include SPI interfacing?
