Playlist auto advancing, and not showing clips.

[davidschober]

Description

When a playlist with a segment as the first item loaded, the player shows the full length of the movie until a user clicks on the segment. This seems unique to our instance of Avalon (the current pawpaw instance does not have this bug.

To recreate:

Create a public or a private playlist add a segment add another segment add another one go to playlist, note that the full media object loads in the player rather than the segment click on the segment, see that it loads the segment.

@carrickr or @mbklein do you want to take a look at this one?

[davidschober]

@carrickr @adamjarling can you dig into this one a bit? It's petty serious. On pawpaw, we don't see this error at all.

[davidschober]

@mbklein and @carrickr just wondering if anyone has had a chance to take a guess at what might be happening here.

[davidschober]

Note, @carrickr and I were working through this. It appears that it might be a streaming issue of some kind (RTMP).

@mbklein @carrickr This has been open for a bit. There's faculty training sessions on sept 14. Can someone dig into it?

[carrickr]

After some digging:

When RTMP streaming the file is slow to load but does load, however it loads at 0:00 (start of the masterfile) rather than the time stamp.

On HLS (iOS) the clip does not playback at all, stalls out loading.

We definitely need to solve the HLS problem, however my question (feedback welcome @mbklein ) is if we should solve it here on Avalon 6 with Media Element 2 or push on Avalon 6.2 with the upgraded media element and then solve it there. Once we have a AWS-Staging branch of Avalon 6.2 up for NU we can see if the problem persists with the new ME and respond accordingly.

On Chrome I'm seeing an infinite look regarding preload never completing (check dev console default level events)

[carrickr]

Cookie now authorizes, but it's still not jumping, still digging into this.

Looks like an order magnitude problem, jumps 6 seconds instead of 600

[davidschober]

@carrickr did were you ever able to dig a bit more into this?

[davidschober]

@carrickr @mbklein I'm confused. Does this have an open PR?

[davidschober]

Testing with 6.2 in staging.. Playlists seem to still be totally broken.

@adamjarling and @carrickr or @mbklein can you take a look.

To recreate:

1. Create a playlist
2. add more than one thing to playlist
3. go to playlist
4. See that the first item is skipped as it seems to not be able to negotiate access
5. See that at times clips are not respected.

dug into this and talked to @adamjarling

This is hard to debug because it uses the old coffeescript that is both a mess in terms of code quality and just hard to track with a debugger. This behavior is also entirely rewritten using better practices and code in 6.3 which we are going to aggressively push out early in 2018. The advice was if it all possible punt to 6.3. Worst case is if this continues in 6.3 it will be much easier to debug and fix. Plus any fix we did for 6.2 would not port over due to the total rewrite. If POs are happy with this we can close as a won't fix.

[davidschober]

Abandoning as won't fix. We are going regroup around 6.3
