gstreamer-vaapi
Locked
 
|
Hi, I’m trying to get gstreamer-vaapi installed on an Amazon ec2 GPU instance. When I installed gstreamer on an Ubuntu AMI through apt-get, all gstreamer decoding and encoding commands gave me an error like 'gstreamer-vaapi cannot load library’ (I forget the exact error message). vainfo errored that I didn’t have an x-server running. I assumed I needed a newer version of gstreamer so I tried to build from source using cerbero on a redhat AMI. Cerbero built everything successfully (after I installed yasm by hand). I don’t know how to install the cerbero generated packages on my system (rpm -i *.rpm seemed to have no effect). If someone could explain that to me I would appreciate it. But in any case, I ran 'cerbero shell' and I noticed gstreamer-vaapi was not automatically installed. I’m having difficulty compiling gstreamer-vaapi because of missing dependencies and I just have no idea if I’m on the wrong track to getting this all working together. Can I use cerbero to compile gstreamer-vaapi? What is the right way to build all of this together and install it properly on a machine? Thanks!! _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

I'm not sure if vaapi has support for addon GPU. It works for Intel's onboard graphics now. Check if the onboard graphics supports hardware decode/encode
Also, check if vaapi would work on a VM. How would the Intel GMA be shared across multiple VM on a bare metal hypervisor? There seem to be many variable :) |

The first thing would be to get working vainfo. What kind of GPU does Amazon provide? VAAPI works well on Intel GPUs and some other GPU using the gallium drivers. vainfo should work without an X server running, just it warns about it. If vainfo doesn't work, which is the most basic libva tool, gstreamer-vaapi won't work either. vmjl > > I assumed I needed a newer version of gstreamer so I tried to build from > source using cerbero on a redhat AMI.

Here is some info about these machines: I naively thought this would be easy. I am clearly in over my head :( Back to Ubuntu: After install 'apt install vainfo', it coredumps when I run it.

Hi Tim,
I’m sorry if this is a dumb question, but even after following the README instructions here ( https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/nvenc/README ) I can’t find the element nvenc gst-launch-1.0 rtmpsrc location=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov ! decodebin ! nvenc
WARNING: erroneous pipeline: no element “nvenc" But I have gstreamer-plugins-bad installed: libgstreamer-plugins-bad1.0-0 is already the newest version (1.8.2-1ubuntu0.2).
libgstreamer-plugins-bad1.0-dev is already the newest version (1.8.2-1ubuntu0.2). As far as I can tell, nothing in the sys/ directory of gstreamer-plugins-bad is available on my ubuntu distribution. Any suggestions? Thanks! _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Yes, ubuntu doesn't ship the nvenc plugin by default (they can't because it needs to be compiled against the nvidia headers + libs which are not FLOSS software). So you'd have to compile gst-plugins-bad yourself - it's enough to configure it and then cd sys/nvenc; make; make install in there - no need for all the other plugins. Then by default the plugin will be installed into a different prefix, so you either need to copy it into /usr/lib/../gstreamer-1.0/ manually or set the GST_PLUGIN_PATH variable to where it was installed, so that GStreamer finds it. It's a bit fiddly I'm afraid, but I can assure you it'll work :) Cheers -Tim -- Tim Müller, Centricular Ltd - http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi
I’m stuck again, sorry :( . I configured with the nvidia libraries: LDFLAGS="-L/usr/lib/nvidia-367" ./configure --with-cuda-prefix='/usr/local/cuda’ But building nvenc fails when it tries to make the gl module. Here is the error when I try to make gl directly: ~/gst-plugins-bad-1.8.3/gst-libs/gst/gl$ make Making all in glprototypes make[1]: Entering directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl/glprototypes' make[1]: Nothing to be done for 'all'. make[1]: Leaving directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl/glprototypes' Making all in x11 make[1]: Entering directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl/x11' make[1]: Nothing to be done for 'all'. make[1]: Leaving directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl/x11' make[1]: Entering directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl' CC libgstgl_1.0_la-gstglcontext.lo gstglcontext.c: In function ‘gst_gl_context_get_current_gl_api’: gstglcontext.c:607:22: error: ‘GL_CONTEXT_PROFILE_MASK’ undeclared (first use in this function) GetIntegerv (GL_CONTEXT_PROFILE_MASK, &context_flags); ^ gstglcontext.c:607:22: note: each undeclared identifier is reported only once for each function it appears in gstglcontext.c:608:29: error: ‘GL_CONTEXT_CORE_PROFILE_BIT’ undeclared (first use in this function) if (context_flags & GL_CONTEXT_CORE_PROFILE_BIT) ^ gstglcontext.c:610:29: error: ‘GL_CONTEXT_COMPATIBILITY_PROFILE_BIT’ undeclared (first use in this function) if (context_flags & GL_CONTEXT_COMPATIBILITY_PROFILE_BIT) ^ gstglcontext.c: In function ‘_create_context_info’: gstglcontext.c:990:23: error: ‘GL_SHADING_LANGUAGE_VERSION’ undeclared (first use in this function) if (!gl->GetString (GL_SHADING_LANGUAGE_VERSION)) { ^ Makefile:1125: recipe for target 'libgstgl_1.0_la-gstglcontext.lo' failed make[1]: *** [libgstgl_1.0_la-gstglcontext.lo] Error 1 make[1]: Leaving directory '/home/ubuntu/gst-plugins-bad-1.8.3/gst-libs/gst/gl' Makefile:1403: recipe for target 'all-recursive' failed

Hi, I miraculously got it to compile, replacing everywhere it said # include <GL/gl.h> with # include <GL/gl.h> # include <GL/glext.h> "sudo make install" put the libraries in /usr/local/lib/gstreamer-1.0 however, simply copying the files libgstnvenc.la libgstnvenc.so into /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ or /usr/lib/x86_64-linux-gnu doesn’t seem to install the plugin: gst-launch-1.0 fakesrc ! nvenc WARNING: erroneous pipeline: no element "nvenc" On January 18, 2017 at 1:34:29 PM, Nick Kallen ([hidden email]) wrote:

Probably means NvEncodeAPICreateInstance() failed. Might be a case of driver not being loaded or wrong driver version or something. Or some incompatibility of the SDK and the distro/version you use. It's all a bit painful sadly, the joy of proprietary hardware drivers. Cheers -Tim -- Tim Müller, Centricular Ltd - http://www.centricular.com
