We're using Wowza and JWPlayer 6 with flash and RTMP.
We get reports that buffering occurs in the middle of a movie and also that sometimes the audio will continue to play, but the video will buffer or stop. This seems to be an intermittent problem, but occurs fairly regularly.
Are there any suggestions for how to resolve this or what we should look into that may effect this?
It is probably a waste of time with FFmpeg, as you noticed is noted in the article. If you are going to use Expression 4 Encoder or another one (maybe Handbrake works too, if I remember reports) that does key frame alignment correctly you can have whatever seems necessary. If some of your audience needs 200mbs streams, you can encode a 200mbs rendition. But not later, you have to encode all renditions at once to get alignment.
