0227397339 Set the graphics card used to decode or encode by setting the 
environment variable HW_EN_DEVICE_SET for enncoding and
HW_DE_DEVICE_SET for decoding. The first card is 0, the second 1
and so on. For now only running on Linux.

df9d1a5717 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

4db2217f0d Fallback for hardware accelerated decode to software decode in case 
the GPU can noy handle the dimensions of the frame.
Not yet working, va_config not yet set.

be979cd78c 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.

314177bceb Let the user choose which installed graphics card to use for 
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.

a92ed9fb03 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.

9972600931 Default to AAC audio codec (#135) 
* Adding strict experimental to FFmpegReader and Writer (hopefully allowing all the encoders to be used)

(cherry picked from commit 1bcd1e5)

* init all formats and codecs before checking if valid
