#FLUENT FFMPEG OVERLAY CODE#
The videos will work fine on your website, we are working hard on improving the implementation code and to provide new features. This is a beta plugin and supports Gatsby v4.1.4 only. Easily convert & host small videos on your own. be sure to convert/specify DTS 6 channel audio streamįfmpeg -i input.mkv -strict experimental -map 0:0 -map 0:1 -c:v copy -c:a:1 libmp3lame -b:a 192k -ac 6 output.mp4Īdd Watermark overlay (png) to the center of a videoįfmpeg -i source.mov -i watermark.png -filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" output.mp4Ĭoncat a video with a reversed copy of itself for ping-pong looping effectįfmpeg -i input.mp4 -filter_complex "reverse,fifo concat=n=2:v=1 " -map "" output.Convert videos via FFMPEG.

You can try to following below command. If you want to use the right channel, write 0.1.1 instead of 0.1.0. However the audio stream will have to be re-encoded.įfmpeg -i video.mp4 -map_channel 0.1.0 -c:v copy mono.mp4įfmpeg -i video.mp4 -map_channel 0.1.0 -map_channel 0.1.0 -c:v copy stereo.mp4 You can modify a video file directly without having to re-encode the video stream. $ ffmpeg -i example.mp4 -f webm -c:v libvpx -b:v 1M -acodec libvorbis example.webm -hide_bannerįfmpeg -i audio.xxx -c:a flac audio.flac Mix Stereo to Mono mp4įfmpeg -i input.mov -vcodec libx264 -pix_fmt yuv420p output.mp4 $ ffmpeg -i image-%04d.jpg -c:v libx264 -pix_fmt yuv420p -vf "scale=720:-2" test.mp4 Evaluate which ratio to apply for scaling, then scale with the requisite amount of padding $ ffmpeg -framerate 30 -pattern_type glob -i '*.jpeg' -c:v libx264 -pix_fmt yuv420p gan-1.movĬonvert image sequence of many different sizes and conform to specific frame size $ ffmpeg -loop 1 -i image.png -c:v libx264 -t 60 -pix_fmt yuv420p -vf scale=1920:1080 out.mp4Ĭonvert non-sequentially named Images in a directory $ ffmpeg -i image-%03d.png -c:v libx264 -pix_fmt yuv420p test.mp4 $ ffmpeg -f image2 -i image%d.jpg imagestovideo.mp4 $ ffmpeg -i video.flv image%d.jpg Convert Images into a Video $ ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4 Split a Video into Images Ss offset = frame number divided by FPS of video = the decimal (in milliseconds) ffmpeg needs i.e. $ ffmpeg -ss $1 -i $2 -qmin 1 -q:v 1 -qscale:v 2 -frames:v 1 -huffman optimal $3.jpg
