Vlc using vdpau, no decoding

[i-rinat]

Hi. Could you check again with VLC of version 2.2.3 or later, please? I believe that VLC 2.2.2 had an issue with creating/destroying/using VDPAU decoder resource.

opensuse 13.1 x86_64
vlc 2.2.4
libvdpau-va-gl1 0.3.6

• vlc pref > input/codecs > hardware decoding = automatic

there is progress

this time video is displayed but no full screen , you can't change the image ratio
hardware decoding is used:

---

...

core debug: using hw decoder module "vdpau_avcodec"

avcodec info: Using OpenGL/VAAPI/libswscale backend for VDPAU for hardware decoding.

...
vdpau_display debug: using back-end OpenGL/VAAPI/libswscale backend for VDPAU

...

i can suspend the video but if i stop the video then vlc crashes

Could you try with libvdpau-va-gl from master branch? I've pushed changes regarding fullscreen scaling some time ago. But that was long after v0.3.6, so there's no point in testing with that version. Also, does it still crash with newer libvdpau-va-gl?

with master branch version 0.39

with vlc pref > input/codecs > hardware decoding = automatic

it seems there is no hw decoding

see the log

it is very different from the previous test where we see clearly that hw decoding is used

with vlc pref > input/codecs > hardware decoding = VA-API via X11
we get

...
core debug: using hw decoder module "vaapi_x11"
avcodec info: Using Intel i965 driver for Intel(R) Haswell Desktop - 1.7.1 for hardware decoding.

opensuse 13.1 x86_64
vlc 2.2.4
libvdpau-va-gl1 0.4.0

vlc pref > input/codecs > hardware decoding = automatic

first test with a flv video
result: vlc crash

second test with a ts video
result : sound but no picture

vlc_nopicture.log.txt

opensuse 42.2 x86_64
VLC 2.2.4
opengl 3.0
intel graphical adapter

libvdpau_va_gl1 is installed by default(not very sure if it is me or the opensuse installer).
what is sure is that libvdpau_va_gl1 is supplied in standard opensuse repo openSUSE-leap-42.2-oss

there is no more problem with Vlc: no more crash or video sizing problem
