* qatar/master: (53 commits) probe: Restore identification of files with very large id3 tags and no extension. probe: Remove id3 tag presence as a criteria to do file extension checking. mpegts: MP4 SL support mpegts: MP4 OD support mpegts: Add support for Sections in PMT mpegts: Replace the MP4 descriptor parser with a recursive parser. mpegts: Add support for multiple mp4 descriptors mpegts: Parse mpeg2 SL descriptors. isom: Add MPEG4SYSTEMS dummy object type indication. aacdec: allow output reconfiguration on channel changes nellymoserenc: take float input samples instead of int16 nellymoserdec: use dsp functions for overlap and windowing nellymoserdec: do not fail if there is extra data in the packet nellymoserdec: fail if output buffer is too small nellymoserdec: remove pointless buffer size check. lavf: add init_put_byte() to the list of visible symbols. seek-test: free options dictionary after use snow: do not draw_edge if emu_edge is set tools/pktdumper: update to recent avformat api seek-test: update to recent avformat api ...
