How to convert this curl command in c#?

What are the best command lines for ffmpeg to convert videos to be HTML5 ready?

• And I mean definitive answers. Like what to put in command line to get results like Vimeo. WebM and H.264 support needed for HTML5.

• Answer:

  ffmpeg -i inputfile.avi -vcodec libx264 -vprofile baseline -preset slow -b:v 500k -maxrate 500k -bufsize 500k -vf scale=-1:360 -threads 0 -acodec libfdk_aac -b:a 96k output.mp4 This profile is h264, multiscreen compatible, even on the old smartphones (maybe on the premium other phones). with 360p resolution. this is a basic line, we could do best if we know what type of content, quality and resolution you want. ffmpeg -i input.mp4 -c:v libvpx -b:v 1M -c:a libvorbis output.webm you an change -b:v value to adapt quality. Same remarks : we could do best if we know what type of content, quality and resolution you want.
