* qatar/master: vorbis: Validate that the floor 1 X values contain no duplicates. avprobe: Identify codec probe failures rather than calling them unsupported codecs. avformat: Probe codecs at score 0 on buffer exhaustion conditions. avformat: Factorize codec probing. Indeo Audio decoder imc: make IMDCT support stereo output imc: move channel-specific data into separate context lavfi: remove request/poll and drawing functions from public API on next bump lavfi: make avfilter_insert_pad and pals private on next bump. lavfi: make formats API private on next bump. avplay: use buffersrc instead of custom input filter. avtools: move buffer management code from avconv to cmdutils. avconv: don't use InputStream in the buffer management code. avconv: fix exiting when max frames is reached. mpc8: fix maximum bands handling aacdec: Turn PS off when switching to stereo and turn it to implicit when switching to mono.
