[FFmpeg-devel] [PATCH] avcodec/nvenc: add repeatSPSPPS flag for streaming

[Agatha Hu]

Still using attachment to prevent word-wrapping.
For video streaming, repeatSPSPPS flag should be set as 1 besides 
disableSPSPPS=0, elsewise if running ffmpeg before vlc/ffmpeg, there 
will be no video header, decoder can't work properly.
