A few notes:
- This bug does not have a descriptive enough title.
- The patch is missing a changelog.

The normal pattern we use is:

for (auto it = source.begin(), end = source.end(); it != end; ++it)
    ...

This avoids resolving .end() multiple times.

> -        if (!m_videoTracks[i]->ended())

> +        if (!(*iter)->ended())
>              return;
> -    

The two loops should have braces.
