The initial values are not checked against the number of block sizes.
Initializing them to frame_len_bits will result in a block size index of 0
in these cases instead of something that might be out-of-range.
Fixes Bug 81.

svq1dec: call avcodec_set_dimensions() after dimensions changed. Fixes NGS00148
vp3dec: Check coefficient index in vp3_dequant() Fixes NGS00145
qdm2dec: fix buffer overflow. Fixes NGS00144
h264: Fix invalid interlaced progressive MB combinations for direct mode prediction. Fixes Ticket312
mpegvideo: dont use ff_mspel_motion() for vc1 Fixes Ticket655
imgutils: Fix illegal read.
ac3probe: Detect Sonic Foundry Soft Encode AC3 as raw AC3. Our ac3 code chain can handle it fine. More ideal would be to write a demuxer that actually extracts what can be from the additional headers and uses it for whatever it can be used for.
mjpeg: support mpo Fixes stereoscopic_photo.mpo
Add a version bump and APIchanges entry for avcodec_open2 and avformat_find_stream_info.
lavf: fix multiplication overflow in avformat_find_stream_info()
lavf: fix invalid reads in avformat_find_stream_info()
lavf: add avformat_find_stream_info()
lavc: fix parentheses placement in avcodec_open2().
lavc: introduce avcodec_open2() as a replacement for avcodec_open().
rawdec: use a default sample rate if none is specified. Fixes "ffmpeg -f s16le -i /dev/zero"
rawdec: add check on sample_rate
qdm2dec: check remaining input bits in the mainloop of qdm2_fft_decode_tones() This is neccessary but likely not sufficient to prevent out of array reads.
cinepak: check strip_size
wma: Check channel number before init. Fixes Ticket240

There were multiple issues, for example might we have to re-run
the decompression when the size of the buffer increased,
we should always use a decompression buffer large enough for
the header (so we do not get stuck when the size is too small).
