Hello,  
About MP4 module, my files are around 100-200MB, 30-50minutes videos.  
When I try to seek more then 14-20min from start, I got “video not  
found” and this error in nginx log:  
2011/11/17 01:17:46 [error] 15463#0: \*19 start time is out mp4 stts  
samples in "/home/host/download/4040292549.mp4

How can I fix this, anyone have this error and know something about ?

Could you show “nginx -V” output ?

Could you create debugging log of the request ?

Thanks a lot. It’s working fine now.

Dealing with this trouble again (nginx 1.0.12, 1.0.14):

2012/04/10 12:06:59 [alert] 22812#0: \*1571 pread() read only 0 of

I believe that I have this patch already applied:  
if (start\_time \< (uint64\_t) count \* duration) {  
start\_sample += (ngx\_uint\_t) (start\_time / duration);  
count -= start\_sample;  
ngx\_mp4\_set\_32value(entry-\>count, count);  
goto found;  
}

The message suggests video.mp4 is corrupted (or just truncated).

The “video.flv” file isn’t likely to be an mp4 file. You have to  
use flv module for flv pseudo-streaming, not mp4.
