ffmpeg settings to convert video to HTML5 mp4 and ogg formats

Use ffmpeg to convert videos to the correct format for HTML5 videos on a Linux shell.

When converting to MP4, you need to use h264 video codec and aac audio codec, because IE11 and earlier only support this combination.

ffmpeg -i input.mov -vcodec h264 -acodecaac -strict -2 output.mp4

In this example, input.mov is converted to output2.mp4, with maximum compatibility, Quicktime support, and no audio streaming.

ffmpeg -an -i input.mov -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -level 3 output2.mp4

For Firefox compatible ogg videos, ffmpeg2theora should be installed. The input file here is the output file of the previous ffmpeg conversion.

The following are the commands:

ffmpeg2theora -o video_out_file.ogv output.mp4
