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.

022d22e581 Fix a regression in the dca parser introduced by dts express support. 
The dca parser needs to check that the framesize is actually of a complete
frame, and not of a partial DTS-HD frame, which is not constant size, and
thus the check would fail.

345d15d2f9 libopencore-amr: remove unneeded buf_size==0 check. 
avcodec_decode_audio3() already checks it before sending the packet to the
decoder.

0093f96d34 pcmdec: return buf_size instead of src-buf. 
The values will always be the same, so this change eliminates an unneeded
variable. It also gets rid of the need to reset src when memcpy() is used.

85579b6381 avcodec: remove the Zork PCM encoder. 
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore
the encoder based on the decoder is also incorrect. There is no good reason to
keep the encoder.
