Error:"Configured Videosink video-output-bin is not worikng"
-
Hi,
No it's not the wrong place, however you might have hit something that nobody else encountered.
From the error message it seems to be looking for the Jack server on your Pi, did you install it ?
-
AFAIK, you should be able to configure it to start automatically on system startup.
Right now, the video sink error doesn't ring a bell
-
I have tried with an app to play mp3 file It gives the same jack error but play the file too.and if I start jack using qjackctl and then run the app the error disappears but sound quality degrades.
Video is still not playing.
Could this due to wrong cross compilation of Qtmultimedia?? -
What option did you pass when configuring ?
-
in qt base
./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi -qpa xcb -gstreamer0.10
and I have build QtMultimedia saperately -
GST_DEBUG=3 ./player gives the following errors
xvimagesink xvimagesink.c:1443:gst_xvimagesink_get_xv_support: error: Could not initialise Xv output and
xvimagesink xvimagesink.c:1443:gst_xvimagesink_get_xv_support: error: No port available
and xvinfo gives no adaptors present
so can it resolved or is there any way to set QtMultimedia to use other videosink?? -
@Haresh Have you resolve the problem? I have similar problem:

I dont realy need sound, only video. -
I made a tiny bit of test code just to get the pi camera up and running, using Qt Multimedia and Camera/VideoOutput in QML. I don't get the xvimagesink-error you get, but i get it if i try to create a pipeline using gst-launch and xvimagesink as sink. So i guess depending on how you use Multimedia, you won't always get xvimagesink.
Also, what camera are you using on the Pi?
I use the RPi camera, and for 2 weeks i got a black screen where i should've got video. Turns out all i had to do was set the framerate and/or resolution to a reasonable value in the Camera class in QML. If not, Qt will try to launch RPi camera with 100 fps and god knows what resolution, which was too much. Got the same problem trying to run a normal webcamera with 30fps on fullscreen. So if you get a black screen where your video should've been, consider trying smaller resolution/framerate, or maybe increase GPU ram in config file in /boot/. Dunno the consequences of the latter, but i saw it being mentioned somewhere. I assume black screen with no errors means video stream is taking too much resources.For the audio, i got no clue, but you can try searching for the files where the error occurs and see if you can find out more related to what spawns the error. Its on git.
You tried running it using sudo? Because all the other errors might just be follow-up errors related to the OS not giving you access to the jack in the first place for all i know. -
Hello,
Got another problem though I have managed to cross compile Qt5 with gstreamer1.0 support it is unable to play HD videos on pi.
I checked using GST_DEBUG=3 and it seems like it still uses gstreamer0.10.
So Do anyone have got HD video playing on pi and can suggest me to get it playing??
