    FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,
Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.
For ffmpeg:

  
## Concat image with video #ffmpeg
# Adds 3-sec fading out title image before video.

# What's going on here: We get title.png image, loop it for 3 sec video, create 3 sec silence, get video.mp4 (framerate 25). Next, we add fade out filter on looped image video, after that we concat our image video, audio silence and main video into one. Easy peasy.

ffmpeg -loop 1 -framerate 25 -t 3 -i title.png -t 3 -f lavfi -i aevalsrc=0 -i video.mp4 -filter_complex '[0:0]fade=out:50:25:alpha=1[title]; [title][1:0][2:0][2:1] concat=n=2:v=1:a=1' output.mp4
