• 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)

• MP4Box / FFMPEG concat loses audio after first clip

  17 novembre 2017, par user1615343

  So I am certainly no expert when it comes to either of these tools, but I have a web-based project that’s executing commands on an Amazon Linux server to concatenate two video files that are uploaded.

  Both files are converted to mp4s first using FFMPEG, and those play perfectly in a browser after conversion :

  ffmpeg -i file1.mpg -c:v libx264 -crf 22 -c:a aac -strict -2 -movflags faststart file2.mp4

  Then, I attempt to combine these two resulting mp4s into a single mp4. I tried using FFMPEG to do this but to no avail. Switching to try MP4Box got me much closer : the videos are concatenated together, but the audio stops playing at the end of the first clip, and the second clip is silent.

  MP4Box -force-cat -keepsys -add file.mp4 -cat file2.mp4 out.mp4

  I’ve tried varying versions of the above command with no better results. Any input is greatly appreciated.

  EDIT : info on .mp4 files using

  ffmpeg -i file1.mp4 -i file2.mp4

  ffmpeg -i 1510189259715DogRunsintoGlassDoor_315a03a8e20acfc.mp4 -i
