Subject: h264parse: default to byte-stream/nalu format (Annex B).
X-Git-Tag: 1.19.3~503^2~2107
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c767be53d6aa73bb396fd500a02fe19cf1f2c12d;p=platform%2Fupstream%2Fgstreamer.git

h264parse: default to byte-stream/nalu format (Annex B).

Always default to stream-format=byte-stream,alignment=nalu if avcC
format was not detected. This is the natural stream format specified
in the standard (Annex.B): a series of NAL units prefixed with the
usual start code.
