Tim-Philipp Müller 2d4c661169 ext/faad/gstfaad.*: If we run into a decoding error, try re-opening the decoder with faacDecInit2() using fake codec ...
Original commit message from CVS:
* ext/faad/gstfaad.c: (gst_faad_init), (aac_rate_idx),
(gst_faad_setcaps), (gst_faad_chain), (gst_faad_open_decoder),
(gst_faad_close_decoder), (gst_faad_change_state):
* ext/faad/gstfaad.h:
If we run into a decoding error, try re-opening the decoder
with faacDecInit2() using fake codec data created from the
data the demuxer gave us. Should fix a whole bunch of
GStreamer-faad problems incl. 'channel coupling not
implemented', 'maximum number of scalefactor bands exceeded'
etc. (#173007, #332892).
