Weather.com Video Sound Is In Slow Motion

[radtek]

When watching a video on Weather.com the sound is going so slow motion and is hard to understand what someone is saying yet the video is fine.

YouTube videos and sound work fine.

Weather.com used to have support but it looks like the stopped their support.

OS is Win 7 64 bit, flash player and java are latest versions

Considering the lack of video on weather.com when I visit it (it insist on only giving me a local weather forecast for the capital of Sweden) and the inability to switch region (it reverts to sweden), I can't even verify.

With some web-fu I managed to grab a video.

The problem seems to be that the video they have up is encoded in a way that makes Pale Moon think the sample rate for audio is 22050 Hz, but the actual stream is 44100 Hz. This is probably due to the fact that they have 2 streams with two different bitrates in it.

Code: Select all

This was solved by Tycho, since the alpha.
Please see this thread: Weather.com sound in videos play at slow speed

Still fixed in Tycho 3. :-)

Further details: looks like the container is reporting the wrong sample rate; especially with HE-AAC (which is used in those videos), with variable bitrates, the actual decoder is the only place where Pale Moon can get the sample rate (from an actually decoded frame). Since this is currently off-loaded in Pale Moon to the operating system back-end, it relies on accurate sample rates being posted in the video container.

In short: weather.com isn't encoding their videos in a web-friendly way.
Plus side is that with our work on the MP4 reader, this will work properly in the new milestone.

Moonchild, I believe it already does. Please see post above yours.

Yes it already does, but the new milestone isn't exactly released yet, now is it?
