How we can streaming adaptive to connection speed ?

[hoangthan]

Hi bros, anyway that help us can upload the stream by SRT protocol which adaptive to the connection speed ?
For example. Streamer want to set resolution to Auto, then the stream quality could be SD/HD/fHD base on connection speed.
Thanks a lot.

Hi,

The resolution won't help you reducing the bandwidth. It is more complicated than that. Moreover most of players/decoders won't support a dynamic resolution on SRT.

You can use the encoder video bitrate to adapt to the network bandwidth.
Also, you can implemement and a pass a SrtBitrateRegulator to the streamer with addBitrateRegulatorController.

Hi @ThibaultBee, thanks for the response.
I noticed the class DefaultSrtBitrateRegulator already has adaptive bitrate update.
I wonder about the resolution and the FPS. If the bitrate is updated with the greater value...then does the resolution and FPS could be adaptive as well ?

[ThibaultBee]

Yes, but DefaultSrtBitrateRegulator is mostly an example. It has never been tested on field.

It is not possible to change neither the FPS or the resolution during live. As I said, most players/decoders won't support this on SRT.
