Details | Review

Steps to reproduce

  1. Go to 'https://www.cbsnews.com/live/'
  2. Check if 'CBS News Live' streaming video is playing

Expected behavior

'CBS News Live' streaming video should play normally.

Actual behavior

'CBS News Live' streaming video won't play and the video playback area is black.
(If you refresh the screen, it will play occasionally.)

Device information

  • Firefox version: 130.0a1
  • Android device model: LG Velvet (Same on other devices)
  • Android OS version: S OS (Android 12)

Any additional information?

I am testing in Republic of Korea.

This is an issue that can be easily identified, but there has been no progress in identifying the issue yet.
Please take a look at this issue and leave a comment.

I am curious whether the streaming video 'CBS News Live' is not playing the same way as in Korea with the Firefox app in the US. I am also curious about the cause and the timing of improvement.

The severity field is not set for this bug.
:tthibaud, could you have a look please?

I can reproduce the bug on Firefox Nightly (131.0a1), Android 14, Samsung S24, with no extension enabled.

I cannot reproduce it on Beta (130.0b9) (with the same device).

Moving to Core/ Audio/video.

Product: Fenix → Core

CBS News Live serves HLS contents so this is regressed by the HLS disabling experiment. It can be worked around by turning on the 'Desktop site' setting to let hls.js play the video. I could not tell how the site decides whether to use hls.js or not, though.

Marking it as blocking bug 1896931 for CBS seems a major news source in the US.

Blocks: 1896931

While cbsnews.com uses hls.js on desktop, it fails to do so for Fenix.
Since it's a major news source in the US, the impact will be huge.
Reverting the change to not break the site for release.

Seems we should figure out what are they doing to choose hsl.js or not? It might be worth a compat intervention or so if this the only site we know about

Agree with this. Lets not jump to conclusions.

Sorry, this didn't make it into 131. Technically it's not fixed in 132 since we're keeping the setting in Nightly and early Beta. Not sure what the status flags should be here.
