B-Frames not working properly
Posted: 24 Jan 2011 23:18
Hi, I use VLC to stream over my network. However, I've noticed that unless I set bframes=0, the video gets jumpy. The more bframes, the more jumpy the video. e.g. imagine a news ticker at the bottom of the screen. If the station is showing a still or a graph (which results in lots of b-frames as the screen doesn't update at all), the news ticker looks like the video has 5 fps or so. Apparently, this is quite an old problem (over 5 years), as I found this:

I'm not quite sure if this is actually a sout-issue, it could be a problem with the decoder.
Here is my entire commandline:
Using VLC 1.1.6
