Luca Barbato 7751e4693d ogg: check that the expected number of headers had been parsed 
Not having the header for a codec is a tell-tale of a broken file.

Luca Barbato 9888ffb1ce mov: check for EOF in long lasting loops 
A quite widespread pattern in the demuxer is read a 32bit unsigned
integer and then loop till this value is reached.

Checking for EOF prevents pathological situations.

Luca Barbato 714508bcb9 vorbisdec: ensure FASTDIV denominator is never 1 
In both usages of FASTDIV the denominator might be 1.

Using a branch could make the function slower than using a normal
division.

Both denominator and numerator can be multiplied by 2 safely and
using shifts is faster than using a branch.

Luca BarbatoandAnton Khirnov 681ed00099 avf: introduce nobuffer option 
Useful in cases where a significant analyzeduration is
still needed, while minimizing buffering before output.

An example is processing low-latency streams where all
media types won't necessarily come in if the
analyzeduration is small.
