VAAPI + clutter
Locked
 
|
Dear all,
I am developing an application to visualize multiple streams. I have 4 GtkWidgets (grid of 4 GtkWidgets) displaying 4 video streams, upon click I want to maximize selected window and upon another click minimize back to 4 Widget view. I am developing it using Clutter-gtk and clutter-gst. It works the way I want in Clutter-gst-2.0, but I want to port it to clutter-gst-3.0 and utilize VAAPI hardware acceleration. The application works and it renders video to 4 Widgets upon start, unfortunately, upon click to get back to 4 grid view, the application crashes. But when supplying this pipeline with avdec_h264 encoder instead of vaapih264dec, it runs perfectly: gst_bin_add_many(GST_BIN(pipeline), videodepay, videoparse, videodec, videoconv, sink, NULL); Initially using vaapih264dec, the application quit with error: libGL error: failed to create drawable After supplying "intel" driver to xorg.conf, I no more experience this error, but the application still scrashes. I am running latest Debian with Gstreamer version 1.10.4-1 which should support VAAPI. There is also another way of rendering the video together with use of GTK and it is the OVERLAY approach which I was writing initially, it works but I wanted to take advantage of OpenGL clutter rendering because of my other applications written the same way. Thank you very much Best regards, Ivo -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

On the other hand, assuming avdec_h264 is a gstreamer library, wrapper,
whatever to libav library https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-libav-plugins/html/gst-libav-plugins-plugin-libav.html or codecs. And according to this: https://wiki.libav.org/Hardware/vaapi Could it be possible that when using avdec_h264, could avdec_h264 be in theory also accelerated via VAAPI? I have very low CPU usage when using avdec_h264 on latest Debian. Does anyone know how to get to know how avdec_h264 is linked to libav and with what compile flags it was compiled with? -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Ok, I ran my application in GDB and this is a result from command bt:

Ok, I have Intel HD4000 accesible via kernel driver i915, actually, according
to this, there is no info about VAAPI for HD 4000 https://wiki.archlinux.org/index.php/Hardware_video_acceleration#Installing_VA-API The error I have is related to i965, could it be the VAAPI is calling i965 which is not even loaded? -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Try 'vainfo' and you see the vaapi-support

As you may notice, that backtrace is useless. You would need to install the
debug packages in order to get a proper backtrace that would get us some idea. In the meantime, I'd suggest you to open a bug in bugzilla, in the gstreamer-vaapi component, detailing you crash, with the backtrace. (If you're using arch linux or gentoo, then you should recompile gstreamer with debug flag) https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces On Thu, 11 Jan 2018 at 11:07, horai wrote: > Ok, I got a Netbeans backtrace > > ��??

It is working. Gstreamer-vaapi open 2 times the connection at the beginning for registering purposes and the third is for the video processing itself. In recent versions of libva and gstreamer-vaapi those messages are not printed anymore in console. > > > > > > > -- > Sent from: http://gstreamer-devel.966125.n4.nabble.com/ > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Thank you very much, could it be that there is a bug in the library causing
Gstreamer to crash? -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
