Is it the same issue?
I was facing the same issue (I am on Debian), installed random additional gst packages, which solved the issue for me. (Sorry, I've installed bunch of them, not able at the moment to pinpoint which one really solved the problem for me)
Indeed. The missing package to install was gstreamer1.0-python3-plugin-loader
, thanks!
Now it works, but I'm limited to 5 images per second, because of the Fraction issue.
from webcam-filters.
Just FYI, same issue here:
webcam-filters --list-dev-caps /dev/video0

When trying to use manual input framerate:
$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3 --input-framerate 10/1
gst-stream-error-quark: Internal data stream error. (1): ../gstreamer/libs/gst/base/gstbasesrc.c(3127): gst_base_src_loop (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
streaming stopped, reason not-linked (-1)
from webcam-filters.
Looks like a bad assumption on my part when parsing device's framerate. Seems like they can be sets as well.
Can you post the output of webcam-filters --list-dev-caps /dev/videoX
?
For me it looks like
'/dev/video0' Capabilites

I've tried to set resolution and framerate manually with the following but without the luck
webcam-filters --input-dev /dev/video4 --output-dev /dev/video6 --background-blur 150 --input-width 800 --input-height 600 --input-framerate '30/1'
Correction, based on @jashandeep-sohi input, changed to
webcam-filters --input-dev /dev/video4 --output-dev /dev/video6 --background-blur 150 --input-framerate '5/1'
which seems to be working.
from webcam-filters.
Oh my! So many options to choose from :)
Ok, I'll think of a patch for this.
In the mean time you should be able to side step the issue, by setting --input-framerate
to one of the concrete framerates. @bobek in your case that would only be 5/1
or 2/1
unfortunately.
from webcam-filters.
In my case (Logitech C920 HD Pro), the capability list is:
$ webcam-filters --list-dev-caps /dev/video0

The only thing is that if one doesn't specify any constraint (like --input-width
), the resolution / framerate chosen is not the best, and moreover the command exits immediately without error instead of staying running:

Yes, this was conscious change. I'm picking the input that's closest to --input{width, height, framerate}
rather than exactly that. Picking the "best" (i.e. the highest framerate, width, height) might not give you the best experience. For example, I doubt you could push 60fps through this without getting some serious frame drops. So the defaults for --input{width, height, framerate}
are a "reasonable" 720p at 30fps and we select a input that's closest to that.
If you'd like to default to 1080p at 30fps (or something else more optimal), I'd just create an alias:
alias webcam-filters='webcam-filters --input-width 1920 --input-height 1080 --input-framerate 30'
from webcam-filters.
Ok, I think I've fixed this. Could you try
webcam-filters==0.2.1a0
and see if that helps?It works better, thanks!
The only thing is that if one doesn't specify any constraint (like--input-width
), the resolution / framerate chosen is not the best, and moreover the command exits immediately without error instead of staying running:Yes, this was conscious change. I'm picking the input that's closest to

Ok, I wasn't aware it was on purpose, so no problem. Thanks for the explanation.
But there is still the other problem that makes it exit instantly after launch if I don't specify any size / framerate constraint. There isn't any error message, the return code is 0
, the light on my webcam is lit for an instant, then everything stops and I get the shell prompt. Do you want me to open another issue for this?

Interesting, yes please. Sorry, I misunderstood that was also an issue. Closing this one.
