ac9d159015 proresdec: Properly make sure an index doesn't run past the limit 
If idx equaled num_coeffs - 1 on entry to the loop, the previous
check failed to break out of the loop.

5bbfe193a0 vocdec: Don't update codec parameters mid-stream 
If we really want to support parameter changes, they need to be
signalled along with the AVPackets as parameter change side data,
not just changing the AVCodecContext parameters when a packet
is demuxed (since there may be other earlier packets yet undecoded).

Something similar was already done for the sample rate in 0883109b2,
but some parameters were left changeable.

This avoids having to recheck the channel count for validity for
each decoded frame in (ad)pcm decoders, unless the decoders
explicitly say that they accept parameter changes.

0ef1660a63 sierravmd: Do sanity checking of frame sizes 
Limit the size to INT_MAX/2 (for simplicity) to be sure that
size + BYTES_PER_FRAME_RECORD won't overflow.

Also factorize other existing error return paths.

3dfc5f551f avfilter: avoid testing float == 0 
This fixes the hypothetical case of rounding errors causing
incorrect values to be used.
We do not use *_EPSILON, because non trivial expressions can contain
errors larger than that making a zero equality test with *_EPSILON
unreliable.

d9cdb7d8d6 pcm-dvd: Support channel configuration changes 
The sample buffering logic does not take into account that the blocksize
could change. Reset the buffer if the channel configuration changes,
since if there are leftover samples, it is most likely a broken or
misconcatenated stream. This could lead to negative numbers for
missing_samples during decoding.

Thanks to Michael Niedermeyer for pointing these out.
