Justin RugglesandLuca Barbato fbc0b86599 lavr: Do not change the sample format for mono audio 
This treats mono as planar internally within libavresample rather
than changing the sample format.

Justin Ruggles c6698dfe7c webpdec: Fix decoding of the huffman group indices. 
Per the specification, "The red and green components of a pixel
define the meta Huffman code used in a particular block of the ARGB
image."

Justin Ruggles f2f2e7627f Check mp3 header before calling avpriv_mpegaudio_decode_header(). 
As indicated in the function documentation, the header MUST be
checked prior to calling it because no consistency check is done
there.

Justin Ruggles 44127546b0 Check if an mp3 header is using a reserved sample rate. 
Fixes an invalid read past the end of avpriv_mpa_freq_tab.
Fixes divide-by-zero due to sample_rate being set to 0.

Justin Ruggles fdbe18b7b0 tiffdec: use a single strip if RowsPerStrip is 0 
The spec does not specify that 0 is an error condition, and there
are samples which use 0 when the whole image is in one strip.

Justin RugglesandDerek Buitenhuis d01e684186 mov: do not set avg_frame_rate in the demuxer 
The track duration is often not reliable or is not the duration
represented by the number of frames. In those cases, avg_frame_rate
was reported incorrectly. Removing this code falls back to the
default calculation in avformat_find_stream_info().

This is a partial revert of commit c3aeaa540.

Justin Ruggles d085f80fa1 webp: add a special case for a huffman table with only 1 symbol 
The vlc reader cannot handle 0-bit huffman codes. For most
situations WebP uses the "simple" huffman coding for this case,
but that will only handle symbols up to 255. For the LZ77 distance
codes, larger symbol values are needed, so it can happen in rare
cases that a normal huffman table is used that only has a single
symbol.

Justin Ruggles 157542ebc1 lavr: fix mixing matrix reduction when normalization is disabled
