Encode/H.264 â€“ FFmpeg
This guide focuses on the encoder x264. It assumes you have ffmpeg compiled with --enable-libx264. If you need help compiling and installing see one of our compiling guides. See HWAccelIntro for information on supported hardware H.264 encoders. There are two rate control modes that are usually suggested for general use: Constant Rate Factor (CRF) or Two-Pass ABR. Rate control decides how many bits
