Unable to play 3gp

[James2516]

Issue description

I'm not able to play a .3gp audio recorded with AMR_WB, it throws the following error:

com.google.android.exoplayer2.source.ExtractorMediaSource$UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor) could read the stream.

None of the above extractors is related to 3gp or awb?

ExoPlayer does not provide support for 3GP. A link to sample content would be useful for someone to add support.

Actually, the mp4 extractor does check for 3gp in the ftyp box. So what we need is to look at the content.

@James2516 - Please could you provide a link to a piece of test content that reproduces this issue? Or email one as an attachment to dev.exoplayer@gmail.com? Thanks.

Here's a sample .3gp audio file: https://files.fm/u/x7j8d4ez
Let me know if you require anything else!

This file doesn't use the 3GP container. It's just an AMR file, which are not currently supported. Providing support is tracked by #2527.
