Prevent re-buffering on changing max bit rate in ExoPlayer

I am using setMaxBitrate provided by DefaultTrackSelector to set max bit rate when user changes video quality.

val parameters = defaultTrackSelector.buildUponParameters()
            .setMaxVideoBitrate(bitrate)
            .build()

defaultTrackSelector.parameters = parameters

But as soon as this function is called, the current buffer is discarded & re-buffering is shown right away. Is there any way to keep playing using old buffer & just load the new buffer using the new bitrate settings like YouTube does?

This issue has been discussed here: https://github.com/google/ExoPlayer/issues/3522 https://github.com/google/ExoPlayer/issues/2250

But there doesn't seem to be any solution yet. Any help regarding this issue would be appreciated. Thanks in advance.
