Correct syntax for downloading video and audio with ffmpeg

[dzigelbaum]

Hi,

I'm triying to download audio and videp with ffmpeg and I see this:

Stream #0:3: Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 4438 kb/s, 29.97 fps, 29.97 tbr, 1k tbn, 59.94 tbc (default)
Metadata:
variant_bitrate : 5925626
id : 3vIKPt3P
Side data:
unknown side data type 24 (1071 bytes)

Whats the correct ffmpeg command to download it?

ffmpeg -i url...? How do I specify the output file?

ffmpeg -i url -c copy output.mp4 (or .MKV, or .TS, whatever you want). You will get the first video stream and the first audio stream.
