Hi there:

 

I am running the file-io example of the "MPEG-4 HE-AAC v2 Decoder" software module.

While I decode the file "short_saturday_v2.mp4" which came along with the software module, playback and the seeking functions (ff and rew) works.

When decoding "short_saturday_v2.aac" and "TwentyYearsGoneBye_48.aac", playback is OK but ff and rew fail with the following error message: "Indexer seek operation failed OR unknown return code from adi_aaci_seek."

It appears to be the function perform_adts_file_seeking() that should do the operation.

 

My hardware/software are all up-to-date per the document's recommendation, as detailed below:

Hardware: BF548 ez-kit, rev.1.4, processor rev.0.2

Software: VisualDSP++ 5.0 update 8.

Software module downloaded: MPEG-4 HE-AAC v2 Decoder (with DAB and DRM support) rev.5.4.0 evaluation.

I opened project group "C:\Program Files\Analog Devices\SoftwareModules\MPEG-4_HE-AAC_v2_Decoder-BF-Rel5.4.0_EVAL\example\file-io\HEAAC_BF548_src\HEAAC_BF548.dpg"

 

Could anyone advise what I might have missed for this file-io example?
