Cncode the 3 qualities in an instance for ABR streamings


#1

I have noticed that the 3 qualities generated by the FFBE200 are different instances, so when for some reason, some of the 3 qualities are restarted, the synchronicity is lost as to maintain a good functioning of an adpatative streaming, the PTS and Keyinterval are they lose, for example to be used in an HLS generated in Wowza.

Can an encoding be done as the following example ffmpeg? (is the one I use to generate other channels with a unicast input)

ffmpeg -i input
-s 1280x720 -acodec … -vcodec … output1
-s 640x480 -acodec … -vcodec … output2
-s 320x240 -acodec … -vcodec … output3
OR:

ffmpeg -i input -filter_complex ‘[0:v]yadif,split=3[out1][out2][out3]’
-map ‘[out1]’ -s 1280x720 -acodec … -vcodec … output1
-map ‘[out2]’ -s 640x480 -acodec … -vcodec … output2
-map ‘[out3]’ -s 320x240 -acodec … -vcodec … output3

I’m waiting for your help, I’m using many of these devices for this function, and I can not make them work well to generate hls adaptive streaming.

Thanks!

My dear friend

Sorry, I don’t quite understand what you mean.
Can you specify what I need to do to help you?

have a good day
