Original commit message from CVS: a52dec: Use a debug category, Output timestamps correctly Emit tag info, Handle events, tell liba52dec about cpu capabilities so it can use MMX etc. dvdec: Fix a crasher accessing invalid memory dvdnavsrc:Some support for byte-format seeking. Small fixes for still frames and menu button overlays mpeg2dec: Use a debug category. Adjust the report level of several items to LOG. Call mpeg2_custom_fbuf to mark our buffers as 'custom buffers' so it doesn't lose the GstBuffer pointer navseek: Add the navseek debug element for seeking back and forth in a video stream using arrow keys. mpeg2subt:Pretty much a complete rewrite. Now a loopbased element. May still require work to properly synchronise subtitle buffers. mpegdemux: dvddemux: Don't attempt to create subbuffers of size 0 Reduce a couple of error outputs to warnings. y4mencode:Output the y4m frame header correctly
