For rtsp vdieo stream, I found only VideoCaptureStream can handle it, otherwise I need to give a file as parameter. If I do not do any config in the VideoCaptureStream...
the test program is simple: ``` import ffmpegcv vidin = ffmpegcv.VideoCaptureStream("rtsp url xxxxx") vfile_out = "ffmpegcv_test_out.h264" vidout = ffmpegcv.VideoWriterNV(vfile_out, 'h264', vidin.fps) with vidin, vidout: i=0 for frame in vidin: #cv2.imshow('image',...

Strang thing happened, but it is not related to the ffmpegcv lib. I picked out the ffmpeg command and execute it on bash. e.g, `ffmpeg -loglevel info -i rtsp:////Streaming/Channels/101 -pix_fmt...
