OME and HLS ABR Rendition names for OvenPlayer

[bchah]

When you set up a playlist in OME you can set labels like "Original", "Proxy", or whatever is needed.

In WebRTC ABR these labels show in OvenPlayer because they are pulled from messages received by OME (OvenPlayer.../providers/WebRTCLoader.js:741)

But in HLS there are no signals coming from OME and the quality information is calculated based on the HLS Manifest (OvenPlayer.../providers/Hls.js:110)

This leads to a user experience where WebRTC quality selection looks like this:

And HLS quality selection looks like this:

Even though I am feeding the exact same parameters to the playlist configuration in OME:

 <Playlist>
<Name>ABR_HLS</Name>
<FileName>hls_abr</FileName>
<Rendition>
        <Name>Original</Name>
        <Video>original_video</Video>
        <Audio>aac_audio</Audio>
</Rendition>

<Rendition>
        <Name>Proxy</Name>
        <Video>proxy_video</Video>
        <Audio>aac_audio</Audio>
</Rendition>

</Playlist> 
<Playlist>
<Name>ABR_WebRTC</Name>
<FileName>abr</FileName>
<Options>
        <WebRtcAutoAbr>false</WebRtcAutoAbr>
</Options>
<Rendition>
        <Name>Original</Name>
        <Video>original_video</Video>
        <Audio>opus_audio</Audio>
</Rendition>

<Rendition>
        <Name>Proxy</Name>
        <Video>proxy_video</Video>
        <Audio>opus_audio</Audio>
</Rendition>

</Playlist>

I don't think this is something that can be easily changed on the OvenPlayer side, until the HLS manifest includes the rendition names somewhere. Is it possible for OME to send these rendition names to the manifest so we can use them in OvenPlayer? Or perhaps there is a way to create this behaviour that I am just not aware of yet!

Unfortunately, HLS doesn't have a good way to do that. We could work around this in a non-standard way, but that's not my style.

So you would not be comfortable including a NAME attribute as part of #EXT-X-STREAM-INF?

I'm afraid that Apple Safari will throw an error when I use an attribute that isn't in the RFC.

I just tried a test with Safari 18.3 (latest) and it read a playlist like this with no problem:

#EXTM3U
#EXT-X-VERSION:7
#EXT-X-INDEPENDENT-SEGMENTS

#EXT-X-STREAM-INF:BANDWIDTH=1000000,RESOLUTION=854x480,CODECS="avc1.4d401f,mp4a.40.2",NAME="480p"
