           Summary: FAAD plugin do not handle AAC LATM transport format
    Classification: Desktop
           Product: GStreamer

            Status: UNCONFIRMED

The FAAD plugin do not searches for LATM/LOAS format in the AAC stream. 

The chain function searches for the sync word (line 1061), but only for the
ADTS syncword (gst_faad_sync method).

My suggestion is:

Adding a new parameter in the src caps of the plugin:

transport{adts,latm}

1) if the transport parameted is set, the plugin must looking for the correct
syncword (latm or adts syncword).

2) if the transport parameter is not set, the plugin look for:
a) First the adts syncword for 17000 Bytes (thats a guess :)
b) If no ADTS syncword was found, looking for LATM syncword.
*) This approach is suggested in cases of continuous streams, such one that
come from a live source, like a dvbsrc->mpegdemux for example.
