When configuring FFmpeg for video hosting, ensure efficient transcoding with settings like:

- Container: MP4 with faststart for streamable videos.
- Video Codec: H.264 for compatibility, using -c:v libx264.
- Audio Codec: Opus for quality, using -c:a libopus.
- Bitrates: Specify max video bitrate (-maxrate:v) and buffer size (-bufsize:v), audio bitrate (-maxrate:a).
- Resampling: Audio resampling to 48kHz with stereo channels.

Example FFmpeg command:
ffmpeg -hide_banner -loglevel error -i input.mp4 -g 52 -c:v libx264 -maxrate:v 1024k -bufsize:v 1024k -s 1280x720 -c:a libopus -af aformat=channel_layouts=7.1|5.1|stereo -maxrate:a 190k -ar 48000 -ac 2 -f mp4 -movflags faststart -map 0:v:0 -map 0:a:0 output.mp4
