Greg, I have done some more analysis, specifically for the case of 3gp nb files. I have confirmed that the parameters are being set correctly. The frame format, DTX mode, mime mode, band mode values all match for a given input 3gp file. This leads me to believe that our codec is expecting the da

Can you provide more details on your problem? Exactly what file format are you attempting (e.g., IETF storage format (specify whether it is using NB or WB), 3GP file, etc)? What format is being signaled to your OMX component? And please give some details on what is missing from the data versus

Greg, I have reviewed these components, but also found that there is an amr file parser. Can you give any insight to what exactly is done in this node? At OMX level, it seems that the frame headers that I need at hardware level have already been stripped from the file. Thanks again for the reply

I believe the 3GP parser in the OpenCore framework strips off everything but the raw AMR stream. Hopefully someone from PV will be able to give you a definitive response. On Dec 2, 11:55 am, chrisk_ti <[EMAIL PROTECTED]> wrote: > Hi all, > > Does anybody know what exactly is the format of amr dat

NB/WB AMR data format

2008-12-02 Thread chrisk_ti
Hi all, Does anybody know what exactly is the format of amr data at the OMX input level? Also, is there any info on what file types and formats are supported by openCore? I have had limited success playing 3gp NB-AMR files and also some success playing basic amr files at 4.75kbps, but no other f
