I've noticed that version of proxy hosted here: http://mingfeiy.azurewebsites.net/ is working. However, latest code version "d3fdebab10edc385076e8cc70424eccf12570644" yields different results and it's not working.

Can we please make sure that code in repository up-to-date with working example? It'd save developers' time...

Here is the proof. Let's take a sample from the page.

The URL to 1st level proxy is the following:

http://mingfeiy.azurewebsites.net/Home/Manifest?playbackUrl=http://amssamples.streaming.mediaservices.windows.net/830584f8-f0c8-4e41-968b-6538b9380aa5/TearsOfSteelTeaser.ism/manifest(format=m3u8-aapl)&webtoken=Bearer%3deyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1cm46bWljcm9zb2Z0OmF6dXJlOm1lZGlhc2VydmljZXM6Y29udGVudGtleWlkZW50aWZpZXIiOiI5ZGRhMGJjYy01NmZiLTQxNDMtOWQzMi0zYWI5Y2M2ZWE4MGIiLCJpc3MiOiJodHRwOi8vdGVzdGFjcy5jb20vIiwiYXVkIjoidXJuOnRlc3QiLCJleHAiOjE3MTA4MDczODl9.lJXm5hmkp5ArRIAHqVJGefW2bcTzd91iZphoKDwa6w8

Here is first 3 lines from the response:

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="AAC_und_ch2_128kbps",URI="http://mingfeiy.azurewebsites.net/api/ManifestProxy?playbackUrl=http%3a%2f%2famssamples.streaming.mediaservices.windows.net%2f830584f8-f0c8-4e41-968b-6538b9380aa5%2fTearsOfSteelTeaser.ism/QualityLevels(125435)/Manifest(AAC_und_ch2_128kbps,format=m3u8-aapl)&token=Bearer%3deyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1cm46bWljcm9zb2Z0OmF6dXJlOm1lZGlhc2VydmljZXM6Y29udGVudGtleWlkZW50aWZpZXIiOiI5ZGRhMGJjYy01NmZiLTQxNDMtOWQzMi0zYWI5Y2M2ZWE4MGIiLCJpc3MiOiJodHRwOi8vdGVzdGFjcy5jb20vIiwiYXVkIjoidXJuOnRlc3QiLCJleHAiOjE3MTA4MDczODl9.lJXm5hmkp5ArRIAHqVJGefW2bcTzd91iZphoKDwa6w8"

This response is correct. And here is what the code in the repo yields for the same input.

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="AAC_und_ch2_128kbps",URI="QualityLevels(125435)/Manifest(AAC_und_ch2_128kbps,format=m3u8-aapl)"

Here is online runnable code snippet that mirrors the current repo code: http://rextester.com/VOKH35266.

Hi Mingfei Yan,

Thank you for this solution you save day. I have translated your controller code to PHP

We have an asset with added text track.
When we try to stream the video on ios/mac devices without content protection everything is fine and user can see closed captions. But when I turn on the content protection (now we modify azure response via hls proxy) closed captions are not rendered. I suspect that something should be added to the proxy to render closed captioning but can't get what exactly.
@mingfeiy do you have any idea how to resolve it?
Thank you

We've setup the proxy, by taking the latest pull.

If we enter the token and Manifest URL here at http://mingfeiy.azurewebsites.net/ setup, and get the HLS URL, and open this on safari or in iPhone SKD's AVPlayerViewController it plays the video fine.

If we enter the token and Manifest URL to our proxy setup, get the HLS URL, provide this to iPhone safari or even in iPhone SDK, it doesn't play the video.

Here're the scenarios, so far:

1. We had to provide the token to http://mingfeiy.azurewebsites.net/ proxy with a prefix of Bearer=long_long_long_token which works fine.
2. If we enter the same Bearer=long_long_long_token to our proxy setup, it can't play the video on the embedded AzurePlayer on home page, and it shows Unable to decrypt the encrypted video source 0x20500004
3. If we enter token without Bearer= prefix, it can play the video on the homepage in embedded AzurePlayer. But the HLS URL generated isn't playing the video on safari or in iPhone sdk.

What changes have been introduced b/w both versions that are preventing the latest proxy to play the video? Or are we missing something else?

The code is the repository and sample does not work when the Asset Name contains the space. It's due to improper URL encoding.

It makes 2nd level HLS playlist to contain malformed URIs like that (notice not encoded spaces):

#EXTINF:6.006000,no-desc
http://xxxx.streaming.mediaservices.windows.net/00000000-b4bd-4800-8d88-8fbbc0f53a41/SpaceX Interplanetary Transport System 2.ism/QualityLevels(394896)/Fragments(video=180180000,format=m3u8-aapl)

Is there one? if not, please update this.
