I'm launching encoding ffmpeg using GPU with 2 outputs: one using H264_NVENC and one using HEVC_ENV.

To enable video stats output I'm putting -vstats before input file. To specify output of video stats for each output I'm putting -vstats_file <output>.vstats.txt before each output file name.
But I'm getting video stats only for last speficied output and with name of last specified -vstats_file option.

How to enable multiple video stats output (different codecs uses different I, P, B frames)?
