[QUOTE="joecrow, post: 1199333, member: 128337"] Hi After much testing I have somewhat isolated the problem of the long stop. I does not occurr if I set Hardware Decoder to use" for Hardware Accelaration to none in LAV filters. As soon as I use DXVA2 Copy Back for hardware accel. the long stop appears in both Madvr and HEVC branches regardless of EVR or Madvr, sorry I did not try in the std. 1.15. The problem only seems to happen with a GPU that supports HEVC, i.e I do not recall it being so bad when I was using a non HEVC AMD GPU(HD6670) either with Catalyst or Crimson drivers, but would need to retest to be 100% sure. Deselecting HEVC from hardware accelaration in the LAV also does not help. The bottom line is that the problem is not specific to Madvr, or the Madvr branch but seems to be a LAV/DXVA2 copyback/AMD RX 460 issue (assumming no one has seen this with Nvidia or Intel GPUs that support HEVC etc. Hope that helps toward a resolution.;) So I can avoid the long stop by not uising hardware accel. but then I have a heavy CPU load when viewing HD TV.:rolleyes: I will try thje new Dshowhelpers and report back tomorrow, maybe.:p [/QUOTE]
