Answer 1

1. appendBytes understands FLV only by default.
2. In order to play mp4 (or any other than FLV format) you need to use appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN) so that Flash reads file correctly. This is quite a flaky proposition anyway.
3. appendBytes must be called after play(null) is called. Otherwise Flash throw an error.
Correct sequence:
     ns.play(null);
     ns.appendBytes(ba);
Incorrect sequence:
     ns.appendBytes(ba);
     ns.play(null);
