  • FFmpeg concatenation and rotation

    6 décembre 2017, par xcentric

    I’m trying to concatenate two videos using the FFmpeg, I can successfully concatenate two files into the one but the problem is when I try to concatenate two videos one which is recorded in portrait orientation and the second one which is in landscape mode. The resulting video will always be in landscape. That means that portrait video will be automatically rotated 90 degrees counterclockwise. Is there a way to prevent this behavior and to just have resulting video with landscape aspect ratio but with portrait video inside of it (it can have dark bezels on both sides it doesn’t matter)

    Long story short : Concatenate portrait and landscape video and as a result get landscape video (but without rotating portrait video beforehand)

    The FFmpeg instruction I’m using for concatenation is :

    ffmpeg -i portrait-video.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate-file1.ts
    
ffmpeg -i landscape-video.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate-file2.ts
    
ffmpeg -i "concat:intermediate-file1.ts|intermediate-file2.ts" -c copy -bsf:a aac_adtstoasc output-video.mp4

  • ffmpeg .iff image sequence to video

    3 septembre 2013, par rajat

    I have a file sequence of format test2#.iff, and i want to convert this sequence to a video, i have tried following commands :

    ffmpeg -f IFF -r 25 -start_number 75 -i "test2%d.iff" -vcodec libx264 test2.mp4
    
Error: test2%d.iff: No such file or directory
    

    
ffmpeg -f image2 -r 25 -start_number 75 -i "test2%d.iff" -vcodec libx264 test2.mp4
    
Error: [image2 @ 00000000002ee220] Could not find codec parameters for stream 0 (Video: none): unspecified size Consider increasing the value for the 'analyzeduration' and 'probesize' options test2%d.iff: could not find codec parameters

    I also have tried various codecs but it gives me same errors, can any of you please shed some light on what might be wrong ?
