Audio fails when seeking with ngx_http_mp4_module

[Igor Ajdisek]

When you try to seek into the part of the video that hasn't been downloaded yet, video continues but audio disappears, although mp4 fIle requested contains moov atom at the begging and flash player sends ?start=0 with initial request.

This happens only with ngx_http_mp4_module. If we use nginx with compiled ngx_mod_h264_streaming module this works without any issues with the same file on the same server (kernel).

Tested with JW and Flowplayer.

Could you try the latest version: 1.1.9 ?

[Igor Ajdisek]

It seems 1.1.9 also has this issue.

nginx version: nginx/1.1.9

Could you create debug log of the request ?

[Igor Ajdisek]

starts with ?start=0
and then seek is made to ?start=136.01
error message: "client closed prematurely connection while sending mp4 to client"

full log available here:

[Maxim Dounin]

This should be fixed in 1.1.12 (r4383), the problem seems to be the same as in ticket #72.

Great news! Thanx!
