When I tried to play an encrypted file using the same codes of your facing this issue.

ExoPlayerImplInternal: Source error. com.google.android.exoplayer2.source.UnrecognizedInputFormatException: None of the available extractors (MatroskaExtractor, FragmentedMp4Extractor, Mp4Extractor, Mp3Extractor, AdtsExtractor, Ac3Extractor, TsExtractor, FlvExtractor, OggExtractor, PsExtractor, WavExtractor, AmrExtractor) could read the stream. at com.google.android.exoplayer2.source.ExtractorMediaPeriod$ExtractorHolder.selectExtractor(ExtractorMediaPeriod.java:973) at com.google.android.exoplayer2.source.ExtractorMediaPeriod$ExtractingLoadable.load(ExtractorMediaPeriod.java:891) at com.google.android.exoplayer2.upstream.Loader$LoadTask.run(Loader.java:381) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) at java.lang.Thread.run(Thread.java:764)

That's usually because it's being encrypted or decrypted wrong, but could also mean your source file is not supported (not mp4 or similar)

i facing same issue, first time it plays right but after that it does not play at all.

First time it plays because the key and iv are generated by SecureRandom which is stored in memory are used for both encryption and decryption.

However when you restart the app, new key and iv is generated by SecureRandom so it will not match the old ones used to encrypt the file.

A fix to this issue will be to change and explicitly define your keys. And use the same keys to encrypt and decrypt the file.

byte[] key = { 65, 66, 67,65, 66, 67,65, 66, 67,65, 66, 67,65, 66, 67,16}; byte[] iv = { 65, 66, 67,65, 66, 67,65, 66, 67,65, 66, 67,65, 66, 67,16};
