  • ffmpeg Concatention - negative pad values

    15 décembre 2015, par mmmyum

    I’m relatively new to ffmpeg and having an issue concatenating some videos.

    Occasionally, I’m running into an issue with my command that is producing negative pad values, preventing the concat from completing. Check out this gist for details and the command output.

    Brief summary is that I’m using filter_complex to scale down and/or pad videos. You can see the full commands in the above links, but here are examples of the filter text :

    [$count:v]scale=if(gt(ih\,iw)\,-2\,$VID_WIDTH):if(gt(ih\,iw)\,$VID_HEIGHT\,-2),pad=$VID_WIDTH:$VID_HEIGHT:(ow-iw)/2:(oh-ih)/2,setsar=sar=1/1[v$count];

    where $VID_WIDTH and $VID_HEIGHT are the smallest dimensions of the inputs.

    I’m concatenating hundreds of videos (in different groups), the vast majority of which work without issue - but occasionally I run into this negative pad values issue. I assume it’s because the input width/height is larger than the output width/height, so it produces a negative value, but I’m not sure how to fix this - I need the videos to be centered.

    Other details :

    • most videos are shot on a cell phone, in a portrait orientation (some in landscape, but I’d like to stitch them in portrait anyways)

    • very rarely I run into a video rotated 90 degrees (larger width than height) - not sure how I should handle this, but one issue at a time

    • usually all videos have the same dimensions, but occasionally one or more videos in a group will have slightly different dimensions, sometimes just by a couple pixels (see attached gist for example)

    • scripting everything in bash right now
