5cf7c72757 shorten: use the unsigned type where needed 
get_uint returns an unsigned value, use an unsigned to store
blocksize to make sure the comparison logic is correct and report
correctly the error for the channel count not supported.

96d2e4d61a Use uint8_t instead of uint16_t pointer in kega decoder. 
This change allows to remove a few casts and avoids
a potential pointer aliasing violation.

4987faee78 h264: check for luma and chroma bit dept being equal 
The decoder assumes a single bit depth for all the planes
while the specification allows different bit depths for luma
and chroma.

29d8cd265a mp3dec: Fix VBR bit rate parsing 
When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag.

When parsing the stream, don't override the bit rate if it's already set,
otherwise calculate the mean bit rate from parsed frames. This way, the bit
rate will be set correctly both for CBR and VBR streams.
