While "acceptable quality" is to the best of my knowledge not a defined metric, it may be useful to measure the quality of an encoding of your given stream: In general, high quality input produces better encodings for a given bitrate. Before actually using this, you should test with many known "good" and "bad" streams to actually verify this for your use case.
