Hello,
I was wondering if I installed all the gstreamer plugins I need and I found this site: There is a particular command that checks if video output gets displayed. With ximagesink I get the output I expect while xvimagesink displays this message : I'm using Ubuntu 16.04 inside a virtual machine. How should I solve this problem? Thank you _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi,
Do you have Xorg running in your virtual machine or is it console only? If it's console only, it will not work. Try running the "xvinfo" command to make sure that your X / drivers are installed correctly. Question, what do you need to implement? If you don't need to display video on the screen and just need to write into a file or stream it somewhere, it might not be worth installing X just for this test. If you want to check whether video can be displayed but don't want to have X running, you can try with aasink or cacasink - they'll use ASCII art on your console.

Hello Vivia,
Thank you for replying. >Do you have Xorg running in your virtual machine or is it console only? I don't think I have them installed, unless they were installed automatically. >Try running the "xvinfo"command to make sure that your X / drivers are installed correctly. This is the output. X-Video Extension version 2.2 screen #0 no adaptors present I guess it's not installed properly. >Question, what do you need to implement? Actually, I'm working on a media player project . I need to display video on screen. I was checking if gstreamer plugins were installed correctly because I got an error in my project. > If you want to check whether video can be displayed but don't want to >have X running, you can try with aasink or cacasink - they'll use>ASCII art on your console. I can't do that ( I think ). Gstreamer is a backend for the library I'm using for my project. I looked through the source files and I saw that for video output it checks for: gconfvideosink, autovideosink, xvimagesink and ximagesink in that order. I would need to edit the source files. What would you suggest to install? Could you provide me a link ? I know I'm asking for a lot but I don't want to break something without knowing. Thank you ! _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi Tatiana,
Refer to the Ubuntu documentation about how to install the default desktop environment (do they still use Unity nowadays? I don't know what the package name should be in any case?). Start the desktop environment, log in graphically, open a console in there, and then it should work out of the box. I *think* that the package you want to install is simply called ubuntu-desktop , but I might be wrong.
