* newdev/master: (33 commits) Fix an infinite loop when RoQ encoded generated a frame with a size greater than the maximum valid size. Add kbdwin.o to AC3 decoder Detect byte-swapped AC-3 and support decoding it directly. cosmetics: indentation Always copy input data for AC3 decoder. ac3enc: make sym_quant() branch-free cosmetics: indentation Add a CPU flag for the Atom processor. id3v2: skip broken tags with invalid size id3v2: don't explicitly skip padding Make sure kbhit() is in conio.h fate: update wmv8-drm reference vc1: make P-frame deblock filter bit-exact. configure: Add the -D parameter to the dlltool command amr: Set the AVFMT_GENERIC_INDEX flag amr: Set the pkt->pos field properly to the start of the packet amr: Set the codec->bit_rate field based on the last packet rtsp: Specify unicast for TCP interleaved streams, too Set the correct target for mingw64 dlltool applehttp: Change the variable for stream position in seconds into int64_t ...
