f44059d260 dca: return proper error codes instead of -1 2011-10-29 16:04:06 -04:00

46e1af3b0f utvideo: handle empty Huffman trees 
If the frame is filled with the same colour, encoder may produce no data
and the fill value is indicated by zero code length (the rest of symbols
will have 0xFF for code length, meaning invalid).  So such Huffman trees
should be treated specially.

4f4e19480a binkaudio: only decode one block at a time. 
This prevents truncating output due to an output buffer that is too small for
all blocks. There is no limit on the number of blocks in a packet.

eaddd29e00 binkaudio: store interleaved overlap samples in BinkAudioContext. 
This fixes the requirement for the buffer size to be larger than the number of
samples actually decoded.

9a35ff3841 atrac1: decode mono audio directly to output buffer 
For stereo we need to use intermediate planar buffers, but mono does not need
to be deinterleaved so the output buffer can be used directly.

9a173575fd utvideo: account for coupled lines in YUV420 format 
Luma slices in YUV420 colourspace should have height in multiple of two since
they have the same line of chrominance data corresponding to pair of them.

38a4be3fa7 lavf: use number of output pictures for delay checks. 
This fixes false positives of has_codec_delay_been_guessed() for
streams where not every input picture generates an output picture,
such as interlaced H264.

61856d06eb probe: Restore identification of files with very large id3 tags and no extension. 
Restore behavior of identifying files with huge id3 tags as
mp3 at AVPROBE_SCORE_MAX/4. This was broken in r25378 and subsequently
removed in r25929.

7a773d4d59 probe: Remove id3 tag presence as a criteria to do file extension checking. 
This only encourages our users to put id3v2 tags on non-mp3 files to opt
into extension based probing.
