[FFmpeg-user] Changing start number in segment name - ffmpeg mpeg dash encoder

[韦林]

it seems ffmpeg had hardcode starting from 1.
you could modify source code file 'libavformat/dashenc.c’ in function dash_init, member ‘segment_index' of OutputStream.
i’m not sure which unexpected result would be raised up.
