• ffmpeg Conversion issue with 3:2 aspect ratio

  5 mai 2015, par nurma

  Sometimes there is an issue when i try to convert to mp4 using ffmpeg. I’m getting issue "Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height". Maybe, this is because of input video file, that has dimensions 720x480 with aspect ratio 3:2. Please help me, how to correctly convert this type of video.
  This is the command :

   ffmpeg -y -i input.mp4 -i watermark.png -filter_complex 'scale=-2:360,overlay=(main_w-overlay_w)-20:(main_h-overlay_h)-20' -codec:v libx264 -profile:v main -preset slow -b:v 300k -maxrate 300k -bufsize 600k -threads 0 -codec:a aac -strict experimental -b:a 128k -crf 20 output.mp4 1> output.log 2>&1

  Here the error log :

• ffmpeg created timelapse won't play on other players than VLC

  27 février 2019, par theFeiter

  I am creating a Timelapse Video with the following ffmpeg command :

  ffmpeg -r 24 -start_number 7754 -i IMG_%d.JPG -pix_fmt yuv420p -s 1920x1080 Output.mp4

  This works without errors, but when I try to play the .mp4 on my Android Phone it shows an Error : "Unable to play file. Not enough resources"

  With the VLC App : "Currently unable to play this video. Stop the other video and try again"

  When I put the Video through Handbrake It plays fine on all players.

  I tried out changing some ffmpeg options, but nothing helped.

  When I compare the output of ffmpeg -i Output.mp4 from the original with the output from the video out of handbrake it differs only in the video bitrate.

  Are there any other options I can try to change ?

  This is the ffmpeg output :

• Stacking different length videos not working with ffmpeg and -itsoffset

  3 avril 2019, par Lucas Madalozzo

  I developed a video conferencing app that records the video streams separately, and I am now looking for a way to merge them. At the moment I am experimenting with -itsoffset and hstack to stack 2 videos side by side using this command :

  ffmpeg \
  
  -itsoffset 17 -i smaller.mp4 \
  
  -itsoffset 0 -i bigger.mp4 \
  
  -filter_complex hstack=inputs=2 \
  
  -c:v libx264 -crf 23 out.mp4

  The result is a side by side video where both streams remain frozen for 17 seconds then start playing, even the bigger.mp4 video that should start at time 0.

  Any help would be really appreciated !
