Anton Khirnov 4c0080b7e7 wmaprodec: return an error, not 0, when the input is too small. 
Returning 0 may result in an infinite loop in valid calling programs. A
decoder should never return 0 without producing any output.

Anton Khirnov cacad1c058 wmaprodec: require block_align to be set. 
Avoids an infinite loop in the calling programs with decoder not
consuming any input and not returning output.

Anton Khirnov 3e2f200237 roqvideodec: fix a potential infinite loop in roqvideo_decode_frame(). 
When there is just 1 byte remanining in the buffer, nothing will be read
and the loop will continue forever. Check that there are at least 8
bytes, which are always read at the beginning.

Anton Khirnov 8a49d2bcbe xxan: fix invalid memory access in xan_decode_frame_type0() 
The loop a few lines below the xan_unpack() call accesses up to
dec_size * 2 bytes into y_buffer, so dec_size must be limited to
buffer_size / 2.

This misfeature is most likely completely useless and conflicts with

Anton Khirnov 2c54155407 h264: deMpegEncContextize 
Most of the changes are just trivial are just trivial replacements of
fields from MpegEncContext with equivalent fields in H264Context.
Everything in h264* other than h264.c are those trivial changes.

The nontrivial parts are:
1) extracting a simplified version of the frame management code from
   mpegvideo.c. We don't need last/next_picture anymore, since h264 uses
   its own more complex system already and those were set only to appease
   the mpegvideo parts.
2) some tables that need to be allocated/freed in appropriate places.
3) hwaccels -- mostly trivial replacements.
   for dxva, the draw_horiz_band() call is moved from
   ff_dxva2_common_end_frame() to per-codec end_frame() callbacks,
   because it's now different for h264 and MpegEncContext-based
   decoders.
4) svq3 -- it does not use h264 complex reference system, so I just
   added some very simplistic frame management instead and dropped the
   use of ff_h264_frame_start(). Because of this I also had to move some
   initialization code to svq3.

Anton Khirnov 39a9fdd00f yop: initialize palette to 0 
The FATE sample contains some pixels with value 0, but the palette
stored in the file contains only values from 16 up. Because the default

gray dots.
After this commit they change to black dots, which is probably still
incorrect but less visible and doesn't rely on get_buffer() initializing
the data.

Anton Khirnov d9df93efbf mpegvideo: simplify REBASE_PICTURE 
Always evaluate to NULL when the source Picture is not located in the
MpegEncContext.picture array. That will only happen for
next/last_picture_ptr when updating the thread context during h264 frame
threaded decoding, where they will point to elements of ref_list. Since
ref_list is not copied during updating the context and is invalid until
it is constructed for the current slice, there is no point in doing
anything complicated with next/last_picture_ptr, as they will get
updated when the ref_list is filled.
