I am sorry, I meant T530, not L530

Thanks for taking the time to reporting this issue.

These messages are bad news: libva is not able to load i965_drv_video.so

if you could run 

$ LIBVA_TRACE=~/libva-vainfo vainfo

and the library is compiled with logging support, you might know the reason why it is not loading the library.

Now, gstreamer-vaapi should be able to abort and let the gstreamer playbin renegotiate a new decoder (the software one, usually) that might work. But I am not sure if that feature was already there in version 0.5.10.

I see black screen in Epiphany and green screen in Firefox, but Totem works fine. i965_drv_video.so can be successfully loaded.

I suspect that is a different problem, perhaps related with bug #745660

Just a note, it seems to be an Ironlake HW, older than SNB ;)

I think the "need info" flag could be removed since I answered all questions

Indeed.

By the way, what's the reply of this command in your setup

$ file /usr/lib64/dri/i965_drv_video.so

The question is why the VA library is unable to open the driver, what's failing.

Setting back to NEEDINFO, though, above all, this bug looks outside of the scope of gstreamer-vaapi, but a libva's one (or even the distribution) because, given the input, libva is unable to load the backend. It could be because of mismatched symbols, wrong ABI, etc.

Hello, I'm experiencing a similar issue with totem, I also reported to https://bugzilla.redhat.com/show_bug.cgi?id=1123536 (check the last comments)
I'm experiencing this bug since I've upgraded to F23, check my comment in the bug report for version info. I don't know what version of gstreamer1-vaapi is now in F22. VLC works fine with VAAPI.

My vainfo output looks different from Germano's:

It is because your issue is a different problem.

The issue your are facing is described in bug 753099, judging from the log message you commented in https://bugzilla.redhat.com/show_bug.cgi?id=1123536 :

(totem:4561): Cogl-WARNING **: driver/gl/cogl-framebuffer-gl.c:983: GL error (1280): Invalid enumeration value

I forgot to say that Comment #13 is about Thinkpad X220




===== Thinkpad R500 =====
$ file /usr/lib64/dri/i965_drv_video.so
/usr/lib64/dri/i965_drv_video.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=251fa6b7cc6692bf90b5a86002213ed12c165fb8, stripped

Moving to Product:GStreamer, Component:gstreamer-vaapi

This seems to be a problem in the distribution (fedora 22) which is not maintained nowadays.

As comment 13 says, the driver is not installed in the Thinkpad X220, but installed in the Thinkpad R500. 

If the problem persist, please reopen and upload the trace files.
