Mp4 module

luislavena · September 9, 2011, 1:51pm

I’ve commit ngx_http_mp4_module in trunk branch.
The patch for 1.0 and last 0.8 is also available:
http://nginx.org/patches/patch.mp4.txt

The module was tested against JW Player.

The module is not built by default, it should be enabled with
–with-http_mp4_module
If you use 3rd-party mp4 module, it should be removed.
Configuration:

location /mp4/ {
mp4;
mp4_buffer_size 1m; # default 512k
mp4_max_moov_size 10m; # default 5m
}

mp4_buffer_size - initial size of buffer to read mp4 file.
This buffer is also used to keep whole meta data of mp4 file (so
called “moov” atom). Maximum size of moov atom which nginx is capable
to read is set by mp4_max_moov_size.

That’s a good feature
Can you confirm if it’s compatible with proxy cache?

No, currently it can work only with static files.

*) Feature: the module ngx_http_mp4_module.

Or you can use the following patch with nginx-1.0:
http://nginx.org/patches/patch.mp4.3.txt

Documentation is here:
http://nginx.org/en/docs/http/ngx_http_mp4_module.html

Are you planning to include it in your repo packages?

Yes.

Could you create debug log of the request ?
http://nginx.org/en/docs/debugging_log.html

Is this file larger than 4G ?

Thank you. As I supposed it has 64-bit co64 atom, however, it’s strange
that this atom was used for so small size file - 39M.
I will make patch today.

Thank you. As I supposed it has 64-bit co64 atom, however, it’s strange
that this atom was used for so small size file - 39M.
I will make patch today.

Patch for nginx-1.1.3.

I am very curious about what the difference between this modle and the
3rd
modle(http://h264.code-shop.com/trac/wiki/Mod-H264-Streaming-Nginx-Version2).
Which one should I use?

To quote Igors original post: “If you use 3rd-party mp4 module, it
should be removed.”

To my understanding both mod-h264 (code-shop) and mod-mp4 (nginx) are
very similar, as they allow seeking in mp4 files.

The mod_smooth_streaming for Code-shop is the one that is different.

for me,“If you use 3rd-party mp4 module, it should be removed.” just
means they are different.I want to know the detail
Should I use the official mp4 module instead of the 3rd-party one?

Ok,I get it.Thanks very much.

You should use only one of them. If you have issues with 3rd-party,
you can try the official mp4 module. If you have issues with the
official module, you should report them and I wll try to fix them.
