Also: - Don't modify size on early buffer The size is the size of the buffer, not of remaining part. - Use the input caps when manipulating the input buffer Also store in in the sink pad - Reply to the position query in bytes too - Put GAP flag on output if all inputs are GAP data - Only try to clip buffer if the incoming segment is in time or samples - Use incoming segment with incoming timestamp Handle non-time segments and NONE timestamps - Don't reset the position when pushing out new caps - Make a number of member variables private - Correctly handle case where no pad has a buffer If none of the pads have buffers that can be handled, don't claim to be EOS. - Ensure proper locking - Only support time segments https://bugzilla.gnome.org/show_bug.cgi?id=740236
