Here at VideoProc, we also prepare you a step-by-step tutorial about how to install FFmpeg. If you are just getting started, first you'll need to download the source code or a build from the official download page, and install it on your device.
So here in this post, I will introduce 31 most commonly used FFmpeg commands with examples to perform various tasks like converting media formats, trimming videos, extracting audio/video streams, etc. You will need to type commands with your keyboard to transcode multimedia files and streams. It packs many encoders and decoders, making it powerful enough to support almost all common and uncommon multimedia formats.įFmpeg comes with a learning curve especially if you are new to a command line tool.
Obviously what I'm trying to do is burn subs then scale the same video track, or visa-versa.FFmpeg is a free and open-source command line-based tool to handle video, audio, and other multimedia files. My input file is a 1920x1080 file which results in a single file with both a 1920x1080 video track with subs, and then a 1280x720 video track with no subs. Stripping most of the nonsense, this is my current line (using Batch): ffmpeg -i %InputVideo% -filter_complex "overlay, scale=w=1280:h=-1" -map "" -map 0:a:0 -codec:v mpeg2video -qscale:v 4 -codec:a mp2 -b:a 192k output.mpg I'm assuming this is a mapping issue, or something about the order of operation, but I just can't seem to figure it out. I can successfully burn subs, and I can successfully scale, but I can't do both without creating a final file with 2 video tracks. The very short version of what I'm trying to do is burn subs and scale a video at the same time using -filter_complex.
