When the iOS application is not in the foreground, the hardware encoder and decoder become invalidated. There doesn't seem to be a way to query their state so we don't know they're invalid until we get an error code after an encode/decode request. To solve the issue, we just don't encode/decode when the app is not active, and reinitialize the encoder/decoder when the app is active again. Also fixes a leak in the decoder.
