* qatar/master: Add a tool that uses avio to read and write, doing a plain copy of data ARM: fix build with FFT enabled and MDCT disabled lavf: force single-threaded decoding in avformat_find_stream_info avidec: migrate last of lavf from FF_ER_* to AV_EF_* avserver: fix build after the next bump. Conflicts: libavformat/Makefile libavformat/avidec.c libavformat/utils.c Merged-by: Michael Niedermayer <michaelni@gmx.at>release/0.10
