This provides a simple command-line interface live streaming functionality.

They both have the same codec ID of AV_CODEC_ID_H264, but have different names, nvenc_h264 and … In the example below the work will be executed on the gpu with index 1. FFmpeg is an extremely versatile video manipulation utility and used by many related software packages.

Hi All, We have built ffmpeg with both nvidia codec and libx264.
Specifying a codec by name. ffmpeg -i foo.mov -vcodec libxvid -pass 1 -an -f rawvideo -y NUL ffmpeg -i foo.mov -vcodec libxvid -pass 1 -an -f rawvideo -y /dev/null -passlogfile prefix Set two-pass log file name prefix to prefix , the default file name prefix is ''ffmpeg2pass''.

FFMPEG acts as the live stream encoding software. Useful FFmpeg Commands.
