Implement the use of CRF instead od kB/s or MB/s for some formats:
...
VP8, VP9, h264, h265
0 crf with VP9 is lossless
0 crf with VP8, h264, h265 should be lossless

Accelerated encode now supported by Windows and Mac.
...
Only tested on Linux though due to absense of hardware/software.
Tested to compile on Ubuntu 14.04, 16.04, 18.04, and 18.10
Acceleration only available on systems with ffmpeg 3.2 and up
Very early code, work in progress.
Issues to be fixed soon:
if hardware cannot decode because the size is too big it keeps trying.
more interfaces supported like vdpau in Linux
error handling
user interface
Many commented lines of code are still in the source to help people start
who may want to help.

decoding HW_DE_DEVICE_SET and/or encoding HW_EN_DEVICE_SET
Possible options are /dev/dri/renderD128 for the first,
/dev/dri/renderD129 for the second, and so on.

Fix bug with FFmpeg > 3.2 flushing frames

Final frames stored in buffer need to be flushed/drained so that they
can be written to the video file. Credit to Peter for the update.

Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves.
