* qatar/master: (26 commits) fate: use diff -b in oneline comparison Add missing version bumps and APIchanges/Changelog entries. lavfi: move buffer management function to a separate file. lavfi: move formats-related functions from default.c to formats.c lavfi: move video-related functions to a separate file. fate: make smjpeg a demux test fate: separate sierra-vmd audio and video tests fate: separate smacker audio and video tests libmp3lame: set supported channel layouts. avconv: automatically insert asyncts when -async is used. avconv: add support for audio filters. lavfi: add asyncts filter. lavfi: add aformat filter lavfi: add an audio buffer sink. lavfi: add an audio buffer source. buffersrc: add av_buffersrc_write_frame(). buffersrc: fix invalid read in uninit if the fifo hasn't been allocated lavfi: rename vsrc_buffer.c to buffersrc.c avfiltergraph: reindent lavfi: add channel layout/sample rate negotiation. ...
