[FFmpeg-devel] FFMPEG4.0 open mp4 from HTTP server report : stream 1, offset 0x1c33: partial file

[whmiao]

Hi,

I run cmd like: 


ffmpeg -i http://js.a.yximgs.com/udata/W_8_UAn4tpgi8_zh.mp4 e:\test.mp4


It Will report error: stream 0, offset 0x30: partial file 


If i download the file ,save in local storage, run cmd like


ffmpeg -i e:\W_8_UAn4tpgi8_zh.mp4 -y e:\ou.mp4 


It works well.


Full comand line outputs:
