RandomizedMp3Decoder (ExoPlayer library)

java.lang.Object
- com.google.android.exoplayer2.robolectric.RandomizedMp3Decoder

All Implemented Interfaces:

org.robolectric.shadows.ShadowMediaCodec.CodecConfig.Codec
```
@RequiresApi(29)
public final class RandomizedMp3Decoder
extends Object
implements org.robolectric.shadows.ShadowMediaCodec.CodecConfig.Codec
```
Generates randomized, but correct amount of data on MP3 audio input.
The decoder reads the MP3 header for each input MP3 frame, determines the number of bytes the input frame should inflate to, and writes randomized data of that amount to the output buffer. Decoder randomness can help us identify possible errors in downstream renderers and audio processors. The random bahavior is deterministic, it outputs the same bytes across multiple runs.
All the data written to the output by the decoder can be obtained by getAllOutputBytes().
