Hey Guys,

I am getting a ton of these errors on certain videos.

“no mp4 trak atoms were found in”

I have tried changing the mp4\_max\_buffer\_size. However, this has not  
helped me solve the problem.

Is there something else I can try to solve this?

Version  
~# /usr/local/nginx/sbin/nginx -v  
nginx version: nginx/1.0.15

OS  
Debian 6 x86\_64 (Fully updated)

Complete log entry  
2012/04/27 11:27:39 [error] 19642#0: \*1714719 no mp4 trak atoms were

Let me know if there is anything you need.

Actually,

I did a little more testing it seems this is coming from video files  
that missed bytes on the upload.

I was able to fix this by re-uploading the file.

Thanks
