Hi, Thanks for reply.
Another question: I want to print frame number on video, where each frame has their own frame number. If text is set to frame number, the width of some frame number will become different, such as 6, 13 and 370. Is there any way to show the text of frame number and keep the same width of text by adding some space at the same time?

The text is rasterized by the freetype lib, not ffmpeg. See some background on fontsizes at https://www.freetype.org/freetype2/docs/glyphs/glyphs-2.html Regards, Gyan _______________________________________________ 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". _______________________________________________ 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".
