Subject: Problems running gstreamer v4l2 on Yocto
Date: Fri, 15 Aug 2014 15:13:56 +0200 [thread overview]
Message-ID: <53EE0794.40107@dfki.de> (raw)
Dear all,
I am trying to set up a USB webcam with Yocto using gstreamer. The
camera is detected by my Yocto /Poky distro and tested with VLC (build
with yocto).
I am using the following build
==
Build Configuration:
BB_VERSION = "1.22.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "Ubuntu-14.04"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "odroid-xu"
DISTRO = "poky"
DISTRO_VERSION = "1.6.1"
TUNE_FEATURES = "armv7a vfp neon"
TARGET_FPU = "vfp-neon"
meta
meta-yocto = "daisy:87671f72e7459d5d5ddb37691354fab970c557ee"
meta-oe
meta-networking
meta-multimedia
meta-gnome = "daisy:d85b01997ce8cc354ccc53f97fdffc79cf2277d5"
meta-odroid = "master:bbdf8273297e310736c48a7c6490c84fe1dea6d9"
meta-ros = "master:f6ba83122674a80bc4beb03ebfc60ea003493ec0"
meta-gumstix = "daisy:b160dd5ca424e0f8b76871187a76095b06af7d58"
meta-dfki = "master:82995e78f5792a91af0a6ca28f2bc63ce0a904a9"
==
I execute the following command
gst-launch v4l2src device=/dev/video0 ! ffmpegcolorspace ! ximagesink
This works perfectly on my Ubuntu 14.04 laptop as well as on my Linaro
Image (14.04) for my embedded system (using the same camera).
I have build all gstreamer-plugins-* with Yocto.
The very same command on my Yocto distro produces:
==
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device
'/dev/video0' cannot capture at 32768x32768
Additional debug info:

Call to S_FMT failed for UYVY @ 32768x32768: Invalid argument
==
Something wrong with the build config of gstreamer with Yocto?
Cheers,
Markus
