fd095539d1 latmdec: fix audio specific config parsing
Pass the correct size in bits to mpeg4audio_get_config and add a flag
to disable parsing of the sync extension when the size is not known.

Latm with AudioMuxVersion 0 does not specify the size of the audio
specific config. Data after the audio specific config can be
misinterpreted as sync extension resulting in random and wrong configs.

702b73bc9f Fix ext_object_type.
In the case of explicit non-backwards compible PS, the extension object
type should be set to SBR. See 14496-3:2009 (fourth edition).
