ffmpeg mapping to mkv introduces "fake" delay relative to video

LibVLC DXVA2 Windows C++ Hardware Acceleration
15 novembre 2016, par Sergiu VladI want to decode a h264 RTSP stream using DXVA2 Accelerated decoder. In VLC it does work but in my code have the following output :
avcodec generic warning: threaded frame decoding is not compatible with DXVA2, disabled
avcodec generic debug: available hardware decoder output format 61 (dxva2_vld)
avcodec generic debug: available hardware decoder output format 128 (d3d11va_vld)
avcodec generic debug: available software decoder output format 12 (yuvj420p)
core generic debug: looking for hw decoder module matching "any": 1 candidates
core generic debug: no hw decoder modules matchedIs this a problem with NV12 conversion ? Is there a way to force DXVA2 ?
Thanks
