I think I may have found a bug not sure.

if I have a video rendition like this. And I call the medialist like this. It refuses to load the video chunklist, it keeps loading the medialist module. When configuring ABR as sintel\_720, sintel\_1080 its ok.

[http://localhost:1935/playback/amlst:sintel.mp4/playlist.m3u8](http://localhost:1935/playback/amlst:sintel.mp4/playlist.m3u8)

Any ideas ?

```auto
MediaListRendition rendition = new MediaListRendition();
		segment.addRendition(rendition);
		
		rendition.setName("mp4:sintel.mp4");
		rendition.setBitrateAudio(131072);
		rendition.setBitrateVideo((int)resolutionMap.get("bitrate") * 1000);
		rendition.setWidth((int)resolutionMap.get("width"));
		rendition.setHeight((int)resolutionMap.get("height"));
		rendition.setAudioCodecId("mp4a.40.2");
		rendition.setVideoCodecId("avc1.66.30");
	

```

If I configured it like so it seems to be working ??

```auto
MediaListRendition rendition = new MediaListRendition();
		segment.addRendition(rendition);
		
		rendition.setName("mp4:sintel.mp4?videoIndex=0");
		rendition.setBitrateAudio(131072);
		rendition.setBitrateVideo((int)resolutionMap.get("bitrate") * 1000);
		rendition.setWidth((int)resolutionMap.get("width"));
		rendition.setHeight((int)resolutionMap.get("height"));
		rendition.setAudioCodecId("mp4a.40.2");
		rendition.setVideoCodecId("avc1.66.30");

```

The same problem using the source file for the first audio rendition. I have to tell it to load an index ?

```auto
rendition.setType(IVHost.CONTENTTYPE_AUDIO);
		rendition.setWowzaAudioOnly(true);
		rendition.setName("mp4:sintel.mp4?audioIndex=0");
		rendition.setBitrateAudio(131072);
		rendition.setAudioCodecId("mp4a.40.2");
		rendition.setLanguage(lang);
		//set language from code
		rendition.setTitle(languageCode.getDisplayLanguage());

		//configure HLS properties
		WMSProperties props = rendition.getProperties(true);
	    props.setProperty("cupertinoTag", "EXT-X-MEDIA");
	    props.setProperty("cupertinoTag.GROUP-ID", "aac");
	    props.setProperty("cupertinoTag.DEFAULT", index == 0 ? "YES" : "NO");

```
