libvlc showing HD video silences a libvlc doing sound

Postby tmoran » 04 Mar 2011 00:00

I have two old programs running on a dual-core machine. One just runs music playlists (--no-video) and the other I use for video-only video clips. All is fine for 720x480 video, but for a 1440x1080 video clip the sound goes silent and stays silent for some time after that video is done - even through a couple of other lo-res video playlist items. This happens on an ancient (3 yr old) machine, but does not occur on my newer machines. Does libvlc (0.8.6?) in use by different programs have some serialization that forces all work onto one core? Or is there some other problem (and I hope solution)?

You need to use libvlc 1.1.

>use libvlc 1.1
a) will that solve the problem?
b) is 1.1 upward compatible with 0.8.6x? I can't seem to find any "changes" list.

a) 0.8.6 is ancient and has many bugs that we can't help you with.
b) no it is not.

>no, it is not.
Is there a description somewhere of the changes, for those of us who developed programs around the "ancient" libvlc? Or is it so different we should forget we ever heard of the old one, and start over from the ground up with the new one?
Also, if the latter, whta's the life expectancy of the current version before it too is "ancient"?

The major change was done in 1.1, and was removing all the vlc_exception_t things and some functions were deprecated.

However, we plan to keep the 1.1 API for a long time and not break it.

Thanks. I'll see about rewriting my libvlc wrapper code.
