Hello, I have really big problem with Firefox 59. Our media site works fine on Chrome all versions and firefox < 58v; We are using shaka player 1.6, but this error reproduced into shaka player 2.3.3 too. The problem is: After manifest loaded (example into attach) Media resource blob:[...our page...] could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: void __cdecl mozilla::EMEDecryptor::AttemptDecode(class mozilla::MediaRawData *): Failed to convert encrypted AAC sample to ADTS Meanwhile, other content type (not live) works fine May be some codecs not works in newest versions of firefox. Let us know, what can it be
