* avfilter/drawtext: fix box sizingGyan Doshi2018-07-13
| | | | | | | | | At present, box size is clipped to frame size before being drawn, which can lead to the box not fully covering animated text which is longer than one or both frame dimensions. Since ff_blend_rectangle correctly takes care of clipping, it is skipped here which results in correct box sizing

* aadec: add chapters and seekingKarsten Otto2018-07-09
| | | | | | | | | | | | | | | read_packet reads content in chunks. Thus seek must be clamped to valid chunk positions in the file, which in turn are relative to chapter start positions. So in read_header, scan for chapter headers once by skipping through the content. Set stream time_base based on bitrate in bytes/s, for easy timestamp to position conversion. Then in read_seek, find the chapter containing the seek position, calculate the nearest chunk position, and reinit the read_seek state accordingly.

* libavcodec/mpegaudiodecheader.h : detect reserved mpeg idKarsten Otto2018-07-09

* aadec: improve eof detectionKarsten Otto2018-07-08
| | | | | | | | | Remember the end position of audio content in the file and check it during read_packet. There always seems to be other data beyond it, which could be misinterpreted as more audio. Also add some extra avio_read error checks, to bail early in case of a broken/truncated file. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
