Hi,
I use VLC on an atom based HTPC running windows 7 which requires hardware acceleration to correctly play back 1080p H264 video. Upgrading to vlc 2.2.1 broke 1080p playback for me - with dxva enabled playback is a jerky slideshow. Reverting to 2.1.5 has fixed things so I think there is a bug or reversion in 2.2.1 which breaks dxva playback on my system. The GPU is an AMD Radeon 5450, I have the latest catalyst 14.12 drivers installed.
Please let me know if you need any additional debug info.
Thanks in advance for any help resolving this.
