* qatar/master: lavf: Detect discontinuities in timestamps for framerate/analyzeduration calculation lavf: Initialize the stream info timestamps in avformat_new_stream id3v2: Match PIC mimetype/format case-insensitively configure: Rename check_asm() to more fitting check_inline_asm() fate: Only test enabled filters avresample: De-doxygenize some comments where Doxygen is not appropriate rtmp: split chunk_size var into in_chunk_size and out_chunk_size rtmp: Factorize the code by adding find_tracked_method Conflicts: configure Merged-by: Michael Niedermayer <michaelni@gmx.at>
