The framework opus decoder discards some samples after a call to flush(). Because we flush a decoder that is being retained across an input format change, this means that the start of audio gets truncated when transitioning to a new opus stream. See also https://android.googlesource.com/platform/frameworks/av/+/refs/heads/android10-release/media/libstagefright/codecs/opus/dec/SoftOpus.cpp. Avoid this by recreating opus decoders instead of flushing them. It seems fine to do this for all opus decoders as reinitialization should be cheap, OEM-provided implementations may also discard samples and playback shouldn't be interrupted on reinitialization due to the downstream AudioTrack buffer.
