Subject: celtdec : chain_parse_data : check validity of timestamp, create a new one if needed
X-Git-Tag: 1.19.3~507^2~17835
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8561568e1150571948b7db0be454a53ed4efada3;p=platform%2Fupstream%2Fgstreamer.git

celtdec : chain_parse_data : check validity of timestamp, create a new one if needed
celtenc : default framesize is 480
          setcaps : gets framesize and set caps
          enc_chain : sets framesize in caps
          Added frame-size to static caps of audio/x-celt
          Replaced GST_DEBUG_OBJECT by GST_LOG_OBJECT in enc_chain
          setcaps: get frame-size from int instead of string
          setcaps: use default value for frame-size
