• need help on solving my ffmpeg command line

  3 avril 2019, par DRMTV

  i create a small bash script to encode 1080p video , the video will be added with watermark at bottom left and i need to add a black padding on top and bottom

  i tried several way but still no luck , i tried -vf and yes it worked but cant use padding and watermark together , and suggest use filter_complex

  if i use this code directly without bash script it work

  time ffmpeg -hide_banner -i transformers.mp4 -i transformers.ass -loop 1 -i watermark.png -loop 1 -i logo.png -map 0:0 -map 0:1 -filter_complex "[0:0]scale=(iw*sar)*min(1920/(iw*sar)\,800/ih):ih*min(1920/(iw*sar)\,800/ih), pad=1920:800:(1920-iw*min(1920/iw\,800/ih))/2:(800-ih*min(1920/iw\,800/ih))/2;ass=transformers.ass[FID1];[FID1][2:v]overlay=10:${WATERMARKPOSITION}:repeatlast=0:enable='between(t,300,600)'[FID3];[3:v]fade=in:st=1200:d=1.6:alpha=1,fade=out:st=107998:d=1.6:alpha=1[FID6];[FID3][FID6]overlay=10:5:repeatlast=0:enable='between(t,1200,187922)'" -c:v libx264 -minrate 1800k -maxrate 1800k -bufsize 3600k -profile:v high -c:a aac -b:a 128k -profile:a aac_main -movflags faststart -strict -2 -f mp4 -y "transformers.mp4"

  but when i include it with my bash script i got this error ,

  [libx264 @ 0x2a063e0] height not divisible by 2 (300x39)

• How to ffmpeg command execution in ffmpeg4android app

  3 février 2014, par Sanket990

  If i m using ffmpeg4android Play store app and executing command for video trim but they are not working i m using below command for trimming

  ffmpeg -i /sdcard/vide.mp4 -ss 00:10:00 -t 00:12:00 -async 1 /sdcard/cut.mp4

  Above Command Execute but not showing file cut.mp4 in sdcard .if you know another way for video trimming then show me example or link Thanks in Advance

  If i m running this command showing Logcat

  Looks like Vk log is not increasing in size
  /sdcard/vide.mp4 : No such file or directory
  I m already add file in sdcard path
