@rounce

I have fixed this bug. The problem is "Duplicate AUD nal unit problem".

[arty777]

Apple ipad doesn't play for now , you have posted a hotfix?

[arty777]

newestbie , i download your branch https://github.com/newestbie/nginx-hls-module , but when compile have issue

i comment //#include "redefine.h"
compile success, but stil does't work on apple devices ... can you please help us :)

[marcelpoelstra]

@arty777 this issue has nothing to do with the fixes that newestbie made.
It has been there since the beginning, and is easy to fix.
The problem is in Mime type. This module does not send the mime type header for m3u8 by itself, so your browser on IOS doesn't know how to handle the m3u8
I was able to solve that by compiling in the "headers_more" module for NGINX, and add the header "Content-Type: application/vnd.apple.mpegurl" to the m3u8 location.
After that it runs fine, even with the older "not fixed" versions of this module.

[rounce]

nginx conf include mime.types by default:
inside of mime.types
application/vnd.apple.mpegurl m3u8;
Thus, the default nginx configuration already provides the required Content-Type

[marcelpoelstra]

In theory it does, but when you check the m3u8 location for your module with curl, you will find out that the content type header is missing.
I guess it has to do with the m3u8 not being a real file but is generated on the fly.
The only way I could solve that (and it works fine so no problems there) is to force-include the header at the m3u8 location.

[arty777]

without 3-rd part module "headers_more"

location /hdd0/{
add_header Content-Type application/vnd.apple.mpegurl;
....

[marcelpoelstra]

You're right headers_more is not required, my mistake. I had to use it for other custom headers and used it for this header as well but you can do without, like you did.

Your post however clearly shows what I meant ;) So including the Content-type header is for sure the solution.

and wideo doesn't work on ipad , can you please help

[marcelpoelstra]

try to open up the direct m3u8 link in Safari on a Mac (not in another browser and not on a PC!)
If that runs your video it shows you at least that the m3u8 module is working fine.
On the website you link to all video is shown in a Flash player so if that is the only way to show it, it will never run on an Apple device, since IOS devices do not support Flash and will never run the player, let alone the video.
You need to use a player application that is at least multi platform and has support for both native HTML5 (to support IOS, Android and probably some more devices or browsers out there) and fall back to flash when HTML 5 is not supported. That is the only way to get it running on all devices. Google is your friend, there are many of these around.
Last but not least, also make sure you have no crossdomain issues. These are also very common when serving m3u8 and videofiles from different locations or embedded in portal sites. Depending on what CDN is used (or even your own CDN) these can mostly be easlily fixed.

@arty777

I forgot comment out #include "redefine.h"

Can you play this url?
http://125.39.67.194/j.m3u8

[newestbie]

@thevideoxpress @rounce

my issue is not MIME issue.

http://125.39.67.194:81/j.m3u8

made by rounce's original code. it can not play well on iOS.

you can download the mp4 file at here:
http://125.39.67.194:81/j.mp4

The mp4 file was copied from a flv file using "ffmpeg -a copy".
The issue look like DTS/PTS problem, but it isn't.
