Usage is:
./vaapi_transcode input_stream codec output_stream
For example:
- ./vaapi_transcode input.mp4 h264_vaapi output_h264.mp4
- ./vaapi_transcode input.mp4 vp8_vaapi output_vp8.ivf
Does not handle resolution changes on the input stream.

They don't modify AVCodec, no needs to call it at register. They will be
wasteful if these codecs are unused. Instead, call static data initialization
at codecs' init.

The existing code attempts to clear the frame by painting in OVER
mode with transparent black - which is a no-op. As a result if you
have many input frames (e.g. you're using a sequence of svg files),
you'll start to see new frames drawn over old frames as memory gets
re-used.
Switch the code to paint using the CLEAR compositing operator,
which fills every channel with 0 values (setting a source colour
is not required).
Currently the Windows CC_IDENT is ended with '\r\n'. "head -n1" will not
remove the '\r' and this is causing building error in Chromium.
This CL adds "tr -d '\r'" to remove '\r' in the CC_IDENT string. Since in
most cases '\r' only appears at the end of a string/line, this should
work in most cases.
See example:
printf "hello\r\nworld\r\n" | head -n1 | hd
00000000 68 65 6c 6c 6f 0d 0a |hello..|
printf "hello\r\nworld\r\n" | head -n1 | tr -d '\r' | hd
00000000 68 65 6c 6c 6f 0a |hello.|

If first_seq_no is not within the bounds of timelines then a segfault
will occur.
This patch removes the use of first_seq_no within the timelines array
It also adds first_seq_no to the value returned by calc_next_seg_no_from_timelines
(which allows for different values of 'startNumber')

This is done mainly in preparation for the SIMD patches.
- for the 8-bit input, decrease the blend factor precision to 7-bit.
- for the 16-bit input, increase the blend factor precision to 15-bit.
- make sure the blend functions are not called with 0 or maximum blending
factors, because we don't want the signed factor integers to overflow.
Fate test changes are due to different rounding.
