HLS playback issue

We are trying to playback AES-128 encrypted HLS playlist, attaching the Playlist below
CODE: SELECT ALL
#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=164000,CODECS="mp4a.40.2,avc1.66.30",RESOLUTION=320x136
0001/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=496000,CODECS="mp4a.40.2,avc1.66.30",RESOLUTION=400x170
0003/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=696000,CODECS="mp4a.40.2,avc1.66.30",RESOLUTION=480x204
0004/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1328000,CODECS="mp4a.40.2,avc1.4d001f",RESOLUTION=640x272
0006/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1928000,CODECS="mp4a.40.2,avc1.4d001f",RESOLUTION=800x340
0007/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=3128000,CODECS="mp4a.40.2,avc1.4d001f",RESOLUTION=1024x434
0009/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=4128000,CODECS="mp4a.40.2,avc1.64001f",RESOLUTION=1280x544
0010/renditions.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=5128000,CODECS="mp4a.40.2,avc1.640028",RESOLUTION=1920x816
0011/renditions.m3u8


We are not able to playback the above playlist, but if we are playing the master file for each resolutions directly giving the path for that file, that playback works but passing the above playlist is not working can you please help or point why this is happening..?

Appreciate any help/input as this is critical for us to get it working as adaptive streams.

Error which Roku throws up is : Media Format not detected, before throwing this message it tries to download segments but fails and eventually throws the Error message.

Thanks,
Abhi

Re: HLS playback issue

I put your URL into the SimpleVideoPlayer example in the sdk, and it played. Make sure you are setting the StreamFormat to "hls".

Re: HLS playback issue

Hi,

Unfortunately we are still unable to playback the video. The app just freezes after showing part of the progress bar. We are using a Roku 3 with software version 6.2
We are able to play most other streams both encrypted and non encrypted, not sure what is unique about this one. Also we have ruled out any network related issues since the same is playing back on other devices. Is there anything else you suspect

Thanks
Satish

With version 7.0 of the firmware it crashes the box hard, so be happy it just freezes. 😄

I can play back each rendition separately, but it appears to crash when it switches streams. I'm no expert on encryption in HLS, but I noticed that each rendition uses the same key, but a different IV. I wonder if that could be causing the problem. :?:

By the way, you might want to add System Logging to your code to see what's going on:
log = CreateObject("roSystemLog")
log.SetMessagePort(port)
log.EnableType("http.connect")
log.EnableType("http.error")


I haven't looked at the example code, so you may need to add something to the event loop to print the roSystemLogEvent events.
