If you create a 5min source file and split in 5 1 minute chunks with the help of the hls function of ffmpeg. Then create 3 other quality streams form these chunks. This results in a total of 4 hls compatible streams where switching between each of them should be without any problem I think. > It's not a problem to get source file key frames and to have them encoded > into the rest of the files. > The problem is with a live streaming, because it is not possible to query > it for the keyframe lications > > Reuben, > The whole idea is to avoid intense CPU consumption for LIVE streaming. > > > On Sat, May 2, 2015 at 8:31 PM, Reuben Martin <reube...@gmail.com> wrote: > >> On Saturday, May 02, 2015 06:00:32 PM Haris Zukanovic wrote: >>> My case is live streaming. >>> I have tried it and definitely keyframes are not aligned between input >>> and output streams. >>> For all encoded output streams it is very simple to obtain alignement >>> with setting the fixed GOP size.
