[Mp4-tech] MPEG4 Audio - regarding MPEG4 BSAC

[Veerabharathi]

  Hello All,
  I am new to BSAC. I have downloaded the MPEG4 source code and have compiled the mp4v2dec in the rewrite directory. But I am unable to decode any test vectors.
  The input options that I gave are as follows:
  -d 1  c:\ er_bs01_08_ep0.mp4 –o c:\ er_bs01_08_ep0.wav 
  The decoder gives the following error message always.
  mp4audec: MPEG-4 Natural Audio Decoder
  decoding c:\ er_bs01_08_ep0.mp4 -> c:\ er_bs01_08_ep0.wav
  mp4audec: WARNING: error decoding audio file c:\er.mp4
  mp4audec: finished
  Press any key to continue
  Thanking you in advance. Awaiting your early reply.

You can find BSAC conformance bitstreams with PNS tool from following
URL.

Reference Wave :

Please refer to Table 52 in page 25 of w7461.
The test procedure is exactly same to that of MPEG-4 AAC PNS tool.
Thank you.

Importance: High
Dear All,
I had a query regarding MPEG4 BSAC. I would like to know whether the
Audio Object 22 as defined in the MPEG4 standard as ER BSAC support the
PNS coding tool?
If yes, where would I find:
1. Any document/information that specifies the compliance criteria for
the above-mentioned combination.
2. Bit-streams that test the conformance of a test implementation
according to the compliance criteria.
Thanking you in advance. Awaiting your early reply.
Regards,
Veenit.
