gpx2video & hardware acceleration

[progweb]

Branch "feature/qvc" starts the hardware acceleration development.

Of course, it's in progress.

NVEnc

Support for NVEnc h264 & hevc is implemented.

--video-preset: slow, medium, fast, hp, hq, bd, ll, llhq, llhp, lossless, losslesshp, p1, p2, p3, p4, p5, p6, p7
--video-crf: 0 - 51 (default 27 for H264 and 31 for HEV)
--video-bitrate: integer (default 16MB)
--video-min-bitrate: integer (default 0MB)
--video-max-bitrate; integer (default 32MB)

Set 'crf' to -1, to use bitrate, min-bitrate & max-bitrate.

QSV

Support in progress.

--video-preset: veryfast, faster, fast, medium, slow, slower, veryslow

VAAPI

Support in progress. To start to test, just enable "HW_VAAPI" in code to use VAAPI hardware acceleration.

$ intel_gpu_tool

permits to test CPU & GPU load.
