JWPlayer 7.7 HTML5 HLS adaptive streaming not working properly

Hi,

I have installed the new JWPlayer 7.7 to try out the new HTML5 support of HLS for Firefox. I currently use Firefox 48 on Ubuntu.
I have modified the player configuration to use the html5 feature ( hlshtml: true ) and it loads the "caterpillar" provider.

It turned out that the player does not work properly on live HLS video that have different available bitrates. The caterpillar provider, on "auto" mode, stays on the lowest bitrate when the flash provider changes the bitrate properly.

I have also tried tio play HLS playback videos with different bitrates and it works fine; only the live doesn't work.

It there a known bug on that? I have also tried it for Chrome 53, it does not work either.

Here an example of the main m3u8 file:
#EXTM3U
#EXT-X-ALLOW-CACHE:NO
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=64000,CODECS="avc1.42001f",NAME="640x360"
files/poor/index.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=500000,CODECS="avc1.42001f",NAME="640x360"
files/low/index.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1000000,CODECS="avc1.42001f",NAME="1280x720"
files/medium/index.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=3000000,CODECS="avc1.420028",NAME="1920x1080"
files/high/index.m3u8

The files files/*/index.m3u8 look like that:
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:50279
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:2
#EXTINF:2.000000,
live0000050279.ts
#EXTINF:2.000000,
live0000050280.ts
#EXTINF:2.000000,
live0000050281.ts

Thx,
Frederic

Hi there,

Is that particular HLS stream working properly in Firefox on either Windows or Mac? We don’t specifically support our player on Linux, but if the same behavior is happening in Windows or Mac then I will be more than happy to take a look. Also, can you provide me a URL for the HLS stream so I may take a look as that would be the only way I can try to reproduce the behavior?

Thank you.

Hi,

I have tried FF and Chrome on Windows, both have the issue.
I have also tried FF and Chrome on a MacBook air. FF loaded the flash provider and Chrome had the same issue with the caterpillar provider.

How can I send you a private message to give you an access to a live stream?

Thank you for your help.

Hi there,

If you log in to your account dashboard and click “Submit a Case” on the top of the page, you can include the URL in there and it won’t be available on any public forum. In that case submission, please copy and paste your original post and also mention that I (Alex) am helping you and reference case # 91070.

I’ll keep an eye out for that case. Thank you.

It's a little disappointing that this thread didn't continue. He's having the same problem I'm having. Continuing the thread would have helped me to help myself, instead of now having to hit up the support team.

Tim,

The reason why this original conversation did not continue on this post is because the original poster did not feel comfortable putting the URL of their live stream on a public forum, which is definitely understandable. If you feel comfortable posting a URL to a reproduction page or your stream on this forum post, please reply with that information and I will be more than happy to help you.
