  • ffmpeg : jpeg-images with different resolution -> video sequence ; using padding instead of scaling [on hold]

    3 septembre 2013, par user2742503

    I am currently struggling with the following problem using ffmpeg : I have a bunch of jpg-files with different resolution (say, one is 320x240, one is 800x600 etc) and want to create an avi-file using mjpeg as a video codec withn a output-video resolution of 800x600. The images itself should not be scaled in any way, that means : What I want to achieve is to just place the image in the center and fill the remaining space with white or black instead of scaling up the smaller images to the target resolution.

    So far I have used

    ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -s 1920x1080 -qscale 2 -r 25 output2.avi

    or

    ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -vf scale=1920:1080 -qscale 2 -r 25 output2.avi

    in case of scaling to HD resolution.

    Would be very thankful for any support on that !

    Thank you in advance !

  • How to concat two/many mp4 files(Mac OS X Lion 10.7.5) with different resolution, bit rate [on hold]

    3 septembre 2013, par praveen

    I have to concat different mp4 files into single mp4 file. i am using following ffmpeg command but this command is only working if both file is same(copy, or if all video property is same(codec, resolution,bitrate....) ) other wise result is unexpected video. (I am working on Mac OS X Lion 10.7.5)

    ffmpeg -i images/1/output.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
