Patch fixing the issue
I'm testing with some AAC file extracted from live TV stream.
The file starts with LOAS frames with no configuration ("use previous config"
bit set).
On first LOAS frame, this leads to have aacparse->sample_rate at 0 and
aacparse->channels at 0 too.
As the element don't have any src caps set, we try to set src caps with these
sample rate and channels leading to pipeline error.
The fix proposes to avoid setting src caps till we get a valid configuration
from next LOAS frames.
This works correctly with the sample attached (AAC file gdppayed)
Thx
