Video stutter / choppy both SD and HD regardless of resolution or bitrate

[andydupont]

Maddox, I love your work on Wallop and it has caused me to explore ffmpeg and its streaming capabilities. I also had to learn a bit about ruby, home-brew etc. Thanks for the effort you have put into this. The streams I get are usable, but with some issues. Even after letting them line out for a minute or two, I still have issues and am trying to find out what can be done to get smooth HD video (720 p would be OK).

I am using ffmpeg 2.2.2 and have tried different versions of x264.rb as your vendor file does not have a copy. What do you suggest as the best source for x264.rb as the versions do vary greatly?

I get choppy video or stutter and pixilation several times per minute. I am on a desktop Mac with ethernet connection to the HDHomeRun. I am using a quad core i5 running at 3.4 Ghz and 16 GB of Ram.

So my issue seems to be software and not hardware related. Here is a small segment of the ffmpeg log file:

I just made a change in d92ccd3 that might help fix this. Can you try it?
