Ich möchte die Breite und Höhe des Wasserzeichens wie die Breite und Höhe des Videos festlegen. 

String[] cmd={"-i",margefilePath,"-ignore_loop","0","-i","/storage/emulated/0/Download/light2.gif","-i","/storage/emulated/0/Download/04 - Aa To Sahi - DownloadMing.LA.mp3","-filter_complex","[1:v]format=yuva444p,scale="+800+":"+720+",setsar=1,rotate="+angle+":c=black@0:ow=rotw("+angle+"):oh=roth("+angle+") [rotate];[0:v][rotate] overlay=0:0:shortest=1[v]","-map","[v]","-map","2:a:0","-c:a","aac","-shortest","-y","/storage/emulated/0/Movies/video_gif_light2.mp4"};

Wenn ich versuche, mit einem konstanten Wert zu skalieren, funktioniert es nicht immer. Bitte sagen Sie mir, wie Sie das Wasserzeichen dynamisch skalieren können.

String [] cmd = {"- i", margefilePath, "- ignore_loop", "0", "- i", "/ storage / emulated / 0 / Download / light2.gif", "- i", "/ storage / emulated / 0 / Download / 04 - Aa To Sahi - DownloadMing.LA.mp3 "," - filter_complex "," [1: v] [0: v] scale2ref [2nd] [ref]; [ref] [2nd] vstack; [1: v] format = yuva444p; [0: v] overlay = 0: 0: kürzeste = 1 [v] "," - map "," [v] "," - map "," 2: a : 0 "," - c: a "," aac "," - kürzeste "," - y "," / storage / emulated / 0 / Movies / video_gif_light22.mp4 "}; Es ist keine Arbeit. Befehl ausführen unendlich Zeit. p.jadhav vor 5 Jahren 0
