200ee68479 Reading average and peak bitrates from esds boxes.
This provides better compatibility with MediaExtractor, which does read these fields; we also need them for being able to mux file contents into another mp4 file.

Also, there is a minor refactor included so that we have an actual type for esds box contents instead of a pair.

4cf9106581 Transcode to a muxer-supported sample MIME type.
If the output sample MIME type is inferred from the input
but is not supported by the muxer, we fallback to transcoding
to a supported sample MIME type.
The audio and video renderers need to make sure not to select the PassthroughSamplePipeline for this case. Which sample MIME type
to choose is decided by the EncoderFactory.

8b11902752 Throw when inferred sample MIME type is not supported by the muxer.
This is better than silently dropping tracks as done previously. Later,
we will implement fallback to transcoding to a supported MIME type.

458e4b7397 Fix re-encoding after flattening
The decoder is using the SVC NAL unit prefix data on some Samsung
devices.

775983c34b Flip input buffer even if the end of stream is reached.
Sometimes the empty end of stream buffer has a non-zero
data limit. Calling flip first, resets the limit to the
position which is zero in these cases.

88d7b14b49 Do not queue empty input buffers.
Follow-up to a comment on 6f0f7dd1be: Buffers that are useful to pass
to the sample/passthrough pipeline should either contain data or the
end of input flag. Otherwise, passing these buffers along is unnecessary
and may even cause the decoder to allocate a new input buffer which is
wasteful.

9efa32e49b Accumulate remainder in buffer duration calculations.
When dropping the remainder, the decoder and encoder timestamps start diverging after a few buffers when no speed changes are supposed to occur. Tracking the remainder keeps them in sync.

8552345f8f Add PassthroughSamplePipeline for audio.
When no transformation is needed, the passthrough pipeline allows us to skip decoding and re-encoding.

62a35018f8 Separate TransformerAudioRenderer and new AudioSamplePipeline.
`TransformerAudioRenderer` reads input and passes `DecoderInputBuffer`s to the `AudioSamplePipeline`. The `AudioSamplePipeline` handles all steps from decoding to encoding. `TransformerAudioRenderer` receives `DecoderInputBuffer`s from the `AudioSamplePipeline` and passes their data to the muxer.

`AudioSamplePipeline` implements a new interface `SamplePipeline`. A pass-through pipeline will be added in a future cl.

49a93e31d7 Write sample size to dumpfile in transformer tests.
If the number of samples changes, the sizes will help us to verify whether they are just split differently or extra data was added.

c3bce234ca Improve format propagation in transformer
- Store output format in `MediaCodecAdapterWrapper` when we get a format from
  the codec, instead of creating it on demand.
- Make format building code not audio-specific.
- Remove `MediaCodecAdapterWrapper.getConfigFormat` and instead keep track of
  the input/output formats in the renderer. This will mean that the code still
  works if an audio processor changes the audio format in future.
- Make exceptions thrown during audio rendering use the same (input) renderer
  format.
- Misc other minor cleanup.
