Description Mario Kleiner 2012-09-29 21:15:55 UTC

when i tried to test the camerabin2 element in the OSX 2012.9 universal SDK:

/Library/Frameworks/GStreamer.framework/Commands/gst-launch-0.10 -v -m camerabin2

This fails immediately with:

ERROR: from element /GstCameraBin2:camerabin20: Missing element 'encodebin' - check your GStreamer installation.

Indeed encodebin is missing from the SDK.

I've only tested with x86_64 on OSX, but it may be missing from other SDKs, e.g., 32-Bit SDK or Windows SDK as well.

Thanks for reporting, this is fixed in GIT now and this fix will be included in the next release.
Comment 2 Mario Kleiner 2012-11-30 15:22:02 UTC
Retested with 2012.11 SDK. This time the encodebin plugin which was omitted last time is bundled, but now it fails one step further.

If i set camerabin2's "mode" property to 2 for video recording i get:

          Error from element image-encodebin: Your GStreamer installation is missing a plug-in.
           Additional debug info: gstencodebin.c(1703): create_elements_and_pads (): /GstCameraBin2:ptbvideocapturepipeline/GstEncodeBin:image-encodebin:
No available muxer for format 0x124383980.

If instead i leave it at its default of 1 for still image capture, it complains about some missing jpeg encoder:

ERROR: Pipeline doesn't want to pause. 
Got message #59 from element "image-encodebin" (element): missing-plugin, type=(string)encoder, detail=(GstCaps)image/jpeg, name=(string)"JPEG\ encoder";

No available muxer for format 00000000056C9400 

e.g, by calling gst-launch -v -m camerabin2

In any case, now different other required plugins are missing for camerabin2 to work.

Could somebody please test this with some webcam and make sure that at least basic video capture works, before marking the bug as fixed?

Comment 3 Sebastian Dröge (slomo) 2013-02-19 12:35:34 UTC
I can confirm that, it looks like jpegparse or any other element is missing. The error message is a bit misleading
Comment 4 Thiago Santos 2013-05-06 18:20:54 UTC

can you check if you have jpegenc and jifmux in your sdk version? You can try running the following commands from your gst-sdk environment.

gst-inspect-0.10 jpegenc
gst-inspect-0.10 jifmux

I'm testing with current gstreamer-sdk git and I got those 2 installed.

Unfortunatelly at the moment I have no cameras connected to my osx computer, so I'm unable to properly get camerabin2 running.
Comment 5 Thiago Santos 2013-05-07 15:19:08 UTC
So I wrote a small script that sets videotestsrc as the video source for camerabin2 and it works with current git of gstreamer-sdk.

Comment 7 Mario Kleiner 2013-07-03 17:19:03 UTC
Retesting with 2013.6, camerabin2 still doesn't work at all with default settings. I found a workaround for my app, so the problem is "solved" for my purpose, as shown in this commit:


My hunch from reading through the gstencodebin.c code is that maybe the missing "jifmux" plugin or other missing jpeg muxer (formatter?) in the SDK is causing the problem?

Below is the debug output without the workaround, with "image-profile" property left at its default value.
