1258690 - Videos are not played on last.fm

Status: RESOLVED INVALID

(Web Compatibility :: Site Reports, defect)

Description

[Cornel Ionce [:noni] [Hubs QA]]

[Note]:
- this is a bit intermittent, sometimes the video will open for the first time and the second/next times it won't.
- the video is properly opened and played from the context menu (right click -> open in new tab)

[Affected versions]:
- latest 48.0a1 Nightly
- latest 47.0a2 Aurora
- Firefox 46.0b4
- Firefox 45.0.1
- Firefox 4.0

[Affected platforms]:
* Windows Vista x86
* Windows 10 x64
* Windows 7 x64
* Ubuntu 12.04 x86
* Mac OS X 10.8


[Steps to reproduce]:
1. Open Firefox using a clean profile.
2. Open http://www.last.fm/music/Bon+Jovi/_/You+Give+Love+a+Bad+Name or any other song from last.fm
3. Click on the play button.

[Expected result]:
- A youtube link with the video is opened in a new tab and the song starts to play.

[Actual result]:
- Nothing happens.

[Regression range]:
- This is not a regression as it reproduces back to Fx 4.

[Additional notes]:
- nightly console: http://i.imgur.com/9gmF6n6.png (same on Aurora)
- 46.0b4 console: http://i.imgur.com/j3EPoOi.png (same in 45.0.1)
- The song correctly plays if http://www.last.fm/ is opened -> search for an artist (e.g: bon jovi) -> scroll down to songs -> press play (not played if the song name is selected)

When I click play I get redirected to YouTube which says that the video has been blocked on copyright grounds.

The play button is in fact an <a> element instead of <video>. So this should have nothing to do with media playback.

Works in Chrome, but in Firefox on MacOSX nothing happens if I click on the big "play" button. This seems like it's not a video bug, but an event handling bug. Redirecting to DOM > Events.

Olli, WDYT?

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

So when I click, youtube is opened, in Nightly.
And in Chromium the child process crashes, or nothing happens when I click the play button.

Comment 6

[Olli Pettay [:smaug][[e-mail]]]

oh, youtube isn't opened always. In some cases nothing happens.

Comment 7

[Olli Pettay [:smaug][[e-mail]]]

But nothing hints this has anything to do with events at least. Tech evang is like the best guess here, given that the page doesn't seem to work well in other browsers either.

Faulty area.

```html
<div class="video-preview">
    <div class="video-preview-playlink">
        <img src="http://img.youtube.com/vi/KrZHPOeOxQQ/0.jpg" class="video-preview">
        <a class="image-overlay-playlink-link js-playlink" 
           href="http://www.youtube.com/watch?v=KrZHPOeOxQQ" 
           target="_blank" 
           data-youtube-id="KrZHPOeOxQQ" 
           data-youtube-url="http://www.youtube.com/watch?v=KrZHPOeOxQQ" 
           data-track-name="You Give Love a Bad Name" 
           data-track-url="/music/Bon+Jovi/_/You+Give+Love+a+Bad+Name" 
           data-artist-name="Bon Jovi" 
           data-artist-url="/music/Bon+Jovi" 
           title="Play track">
                Play on youtube
            </a>
    </div>
    <a href="#youtube-video" class="video-preview-skiplink">Skip to YouTube video</a>
</div>
```

When I click on the video I get a message in the top part of the window on the mini player "track unavailable".

```js
      this.app.eventMediator.subscribe('player.track.unavailable', this.setErrorMessage.bind(this, 'track-unavailable'))
```

And console.log

This one feel like it's probably INVALID territory.

Certain videos will fail because of Youtube (or other services) rights restrictions. And those can change depending on the uploader, the viewer's region, or Youtube flagging something later on.

See http://www.last.fm/forum/21713/_/2239582/1#f20994596 for a related discussion.

Some videos do work for me, in both Firefox and in Chrome, e.g., 

http://www.last.fm/music/The+Cure/_/Friday+I%27m+in+Love
http://www.last.fm/music/Depeche+Mode/_/Enjoy+the+Silence

And oddly, sometimes the videos are inline. And sometimes they open new tabs. Not sure why, but it's the same in Chrome and Firefox.

If someone can provide STR with a video that fails in Firefox and works in Chrome, I'm happy to dig in further. Karl's invalid message from Comment 9 is the regular video is unavailable codepath from init.js, nothing fishy there.
