[http @ 0x7ff34800a800] Stream ends prematurely at 10350130, should be 335862362

using FFmpegFrameGrabber to intercept frames, the input uses the http stream, but in the process of intercepting frames, after intercepting a period of time it prints a log of the stream ending prematurely, as follows log ： ` Warning: [mov,mp4,m4a,3gp,3g2,mj2 @ 000000000169cbc0] Packet corrupt (stream = 0, dts = 2114701) Warning:

After my test, if the original video quality is high, it takes longer to keep the picture after intercepting it, then this problem will occur, when I use a low quality video I don't have this problem, but I don't know the exact reason, I hope to get help, thanks!
