21d085f8a9 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.

d277deb335 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.

fe1ffdb959 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.

94caa8ad6c Fix re-encoding after flattening
The decoder is using the SVC NAL unit prefix data on some Samsung
devices.

8105394ac2 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.

51901ad568 Do not queue empty input buffers.
Follow-up to a comment on
ac8e418f3d
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.

d8b9d378d9 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.

64466356b2 Add PassthroughSamplePipeline for audio.
When no transformation is needed, the passthrough pipeline allows us to skip decoding and re-encoding.

b87f26490b 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.

52c330c1d7 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.
