Steps to reproduce the problem:
1. Look at Your source file mpeg1_audio_stream_parser.cc, line 141
2. Compare Your condition "if (layer == kLayer2 && kIsAllowed[bitrate_index][channel_mode])" to document http://mpgedit.org/mpgedit/mpeg_format/MP3Format.html, section "For Layer II there are some combinations of bitrate and mode which are not allowed. Here is a list of allowed combinations."
3. Based on this document is correct condition "if (layer == kLayer2 && !kIsAllowed[bitrate_index][channel_mode])"

What is the expected behavior?
Chrome can play MPEG audio Level without problem.

What went wrong?
Chrome can not play valid MPEG audio Level2.
