I can confirm a similar issue. In my case, the problem occurs on older Radeon hardware (HD 3650) which uses the r600 driver. The result is the same, no hardware acceleration is possible through the integrated unified video decoder (UVD). CPU has around 100% load.
It seems that the VA-API is broken, at least for certain systems.
Mesa version: 19.0.8
OS: Kubuntu 18.04.3 LTS with kernel 5.0.0-27
Kaffeine: 2.0.18
