Should be faster and simpler: ffmpeg -i a.webm -i b.webm -filter_complex \ "[0:v]fps=25,scale=320x240:force_original_aspect_ratio=decrease,pad=320:240:(ow-iw)/2:(oh-ih)/2[l]; \ [1:v]fps=25,scale=320x240:force_original_aspect_ratio=decrease,pad=320:240:(ow-iw)/2:(oh-ih)/2[r]; \ [l][r]hstack=inputs=2:shortest=1[v]" \ -map "[v]" output _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
