This avoids setting a negative number of frames, ending up with a
negative average frame rate.

In lpc_prediction(), we write up to array element 'lpc_order' in
an array allocated to hold 'max_samples_per_frame' elements.

Even if the sample rate is valid, an invalid bitrate could
pass the mode combination test below.

Signed-off-by: Martin Storsjö <martin@martin.st>

This avoids divisions by zero later (and possibly assertions in
time base scaling), since an invalid rate_flag combined with an
invalid bitrate below could pass the mode combination test.

Asserting a specific codec is not correct since libavformat
allows forcing a codec, an equivalent check is in the
following line.

Fixes ticket #3001.

This allows supporting files for which the image stride is smaller than
the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file
or a 16x16 VP8 file with -fflags +emu_edge.
