Fix bug in nginx-vod-module

I need somebody who can fix some small bug in an nginx module I am using: [login to view URL] The problem is, there is a glitch in the manifests it returns. The example file in the attachment specifies two French and two German audio tracks with different titles. I have encoded the MP4 file with the following command: ``` ffmpeg \ -i "[login to view URL]" \ -i "[login to view URL]" \ -i "[login to view URL]" \ -i "[login to view URL]" \ -i "[login to view URL]" \ -map 0:v \ -map 1:a -metadata:s:a:0 language=deu -metadata:s:a:0 title="German" \ -map 2:a -metadata:s:a:1 language=deu -metadata:s:a:1 title="German (translation only)" \ -map 3:a -metadata:s:a:2 language=fra -metadata:s:a:2 title="French" \ -map 4:a -metadata:s:a:3 language=fra -metadata:s:a:3 title="French (translation only)" \ -c:v libx264 -vf scale="480:360" \ -r 25 -b:v 400000 -c:a aac -ar 48000 -b:a 128000 \ -t 10 \ [login to view URL] ``` When I run mediainfo, I can see that the tracks are there. ``` # mediainfo --Output="Audio;Audio Title: %Title%\n" [login to view URL] ``` Result: ``` Audio Title: German Audio Title: German (translation only) Audio Title: French Audio Title: French (translation only) ``` However, the manifest that the nginx-vod-module returns is containing only two of the four entries. And the ones it contains have a wrong title, which gets auto-generated by the module: ``` ... <AdaptationSet id="3" lang="fr" label="Français" segmentAlignment="true"> ... ``` The problem can be reproduced reliably (I can show you how), so should be quite easy to find and fix it.
