EXT-X-START does not work since v0.6.9 on single level manifest

[shoys89]

Environment

• The stream has correct Access-Control-Allow-Origin headers (CORS)
• There are no network errors such as 404s in the browser console when trying to play the stream
• The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
• The issue occurs in the latest reference client on http://video-dev.github.io/hls.js/demo and not just on my page

• Link to playable M3U8 file: http://acdn-vs.thuuz.com/test3a4secoff.m3u8
• Hls.js version: 0.8.2
• Browser name/version: Chrome 60
• OS name/version: MAC OS El capitan

Steps to reproduce

1. Go to http://streambox.fr/mse/hls.js-0.8.2/demo/?src=http%3A%2F%2Facdn-vs.thuuz.com%2Ftest3a4secoff.m3u8&enableStreaming=true&autoRecoverError=true&enableWorker=true&dumpfMP4=false&levelCapping=-1&defaultAudioCodec=undefined

2. The following stream has the following tags #EXT-X-START:TIME-OFFSET=4.5,PRECISE=YES, anyway the playback is starting from very beginning instead of 4 second.

Expected behavior

It should start playing from timestamp 4:00
look that this tag was wortking in older HLS version
HLS 0.6.2 = Working
http://streambox.fr/mse/hls.js-0.6.2-2/demo/?src=http%3A%2F%2Facdn-vs.thuuz.com%2Ftest3a4secoff.m3u8&enableStreaming=true&autoRecoverError=true&enableWorker=true&levelCapping=-1&defaultAudioCodec=undefined

Actual behavior

Starting from 00:00 instead of 00:04

Very interesting. I went back through the history and it looks like it broke in v0.6.9 last November. It had been working just prior to that.

good catch, thanks for bisecting.
regression introduced in v0.6.9 by 8db8ea3
only affecting single stream playlist.
should be fixed now

Thanks, Guillaume!

I was also wondering about the "PRECISE" optional value. (I created the sample above and Maverick and I have been working together on a resolution.) I set it to true and used 4.5 to also test the ability to not render frames before the exact desired time, but I noticed there is no occurrence of the word 'precise' in the code base. Is that capability by any chance supported?

Thanks again,
Galan

seeking to the start of the segment containing startOffset is currently not supported, seek to startOffset will always be PRECISE

Awesome, thank you very much, last question, will the fix be in 0.8.3? if yes when it will be released?

Thanks in advanced.

most probably 0.8.3 will be released over the week-end
