[Mp4-tech] Query on EAAC+ test streams

[Shreya Pathak]

Hello Andreas,
       I tried to get the conformance test streams from the FhG ftp-site given by you, but I am not able to access the conformance test streams.
The error what i got when i try to access the site is 
The resource requested could not be accessed. The following response received from the FTP server may contain an explanation.
>>> TYPE A200 Type set to A.>>> PASV227 Entering Passive Mode (153,96,172,3,197,152)>>> RETR /mpeg4audio-conformance/compressedMp4550 /mpeg4audio-conformance/compressedMp4: No such file or directory.

Thanks and Regards
Shreya
