  GStreamer | gst-omx | 1.2.4

           Summary: omxaacenc needs to provide 'profile' in its srccap
    Classification: Platform
           Product: GStreamer
           Version: 1.2.4
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-omx
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: jun.ji at lge.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


My device is QC msm89x6 and my report would be simply stated as below,

gst-launch-1.0 filesrc location=[.wav] 
! wavparse ! omxaacenc ! aacparse ! audio/mpeg,stream-format=adts ! filesink
loc
ation=[.aac]

currently makes a file that can't be identified by 'gst-typefind' but that says
'FAILED: unknown error'. (I found that the output can be playable if it has
been wrapped by 'qtmux'.)

To make the output get a correct adts header,

1. It needs to set and add to the srccap 'profile' in addition to the
'base-profile'. Adding the attribute make the element create a correct adts
header.

2. Currently, gstomxaacenc.c just gives the default value to certain
attributres of OMX_AUDIO_PARAM_AACPROFILETYPE in gst_omx_aac_enc_set_format.
However, in my case, I have to set nSampleRate and nChannel rather than the
nBitRate that gets a default value.



Thanks
Jun
