Bug#899384: vlc: Hardware acceleration fails after upgrade to 3.0.2

[Antoni Marcinek]

Hi,

I downgraded to 2.2.7-1~deb9u1. As I remembered I can increase the
speed up to 64x. The messages in the console are the following:

VLC media player 2.2.7 Umbrella (revision 2.2.7-0-g6e32381286)
[000055798d591178] core libvlc: Running vlc with the default
interface. Use 'cvlc' to use vlc without interface.
Failed to open VDPAU backend libvdpau_i965.so: cannot open shared
object file: No such file or directory

There is nothing about VA-API, nor profile(3). So I wonder what is going on...


Anyway, what about the optirun? I think I did see in some forums
people complaining about it (so it is not just my issue).


Cheers,
Antoni
