Android app is always using x-google-min-bitrate

[prakhar shukla]

My android client app is always using the bitrate value I set in x-google-min-bitrate. If I set it to 8 Mbps the videos are playing in full HD without any FPS drops. But if I set it to 400kbps, the bitrate at client side switches to 400Kbps in 5-10 seconds. I don't have network issues because it videos work fine if I set to higher bitrates. I have a good connection (200Mbps fiber). What could be the reason ? I also tried adding b=AS option in SDP still same issue.

My SDP modification is:

regex = var regex = "a=fmtp:(.*) (.*)".toRegex()

var newSDP = sdp.replace(regex, "a=fmtp:$1 $2;x-google-max-bitrate=26000;x-google-min-bitrate=400;x-google-start-bitrate=6000")

Above SDP modification works fine on my reactjs client. It tries to maintain high bitrate value.

I'm not modifying SDP or doing anything special at sender side.
