Do you have a sample .ac4 stream that could be used to add an Ac4ExtractorTest just like Ac3ExtractorTest?

This looks good to submit once that's added and the comments are addressed. Thanks!

I talked with content creation team. It should be OK to add a sample .ac4 file. After I get approval from legal team, I'll add it into this contribution.

Hi, Andrew,
I have asked content creation team to create sample.ac4 file. And I have one question: How to generate corresponding .dump file in folder library/core/src/test/assets/ts?

@ybai001 You can set the field FakeExtractorOutput.WRITE_DUMP to true temporarily, then copy the file that gets written to the sdcard into the assets directory.

Sorry for the untidy commit history. I‘m not familiar with the working process on GitHub.
BTW, next week is Chinese new year. I'm afraid that I can't reply in time.
