FFmpeg concat filter part 2
16 juin 2020, par Narek AydinyanI have videos. The video files have a different count of video tracks.



video1 = 1 video stream + 1 audio stream.



video2 = 2 video stream + 1 audio stream.



The output result should be
2(concatenated) video streams, 1 audio stream.



The same issue for the Audio case solved in my previous question(FFmpeg concat filter).
Also, I want to mark that I need to generate a video track with custom size.
For example, I can do this with
color
filter but this filter has fixed image sizes(https://ffmpeg.org/ffmpeg-utils.html#toc-Color) 
Thanks in advance

- outro.mp4
What i want to achive :
What i have so far :
ffmpeg -y -i intro.mp4 -r 25 -i "pics/%04d.jpg" -i outro.mp4 -i loop.mp3 -filter_complex
"[0:v:0] [0:a:0] [1:v:0] [3:a:0] [2:v:0] [2:a:0] concat=n=3:v=1:a=1 [v] [a]" -map "[v]"
-map "[a]" -c:v libx264 -pix_fmt yuv420p -profile:v baseline -level 3.0 -crf 20 -r 25
-movflags +faststart -c:a aac -b:a 192k output.mp4But that does not loop "loop.wav". I’v tried "-loop 1" before "-i loop.mp3" but that gives me this error : "Option loop not found."

FFmpeg flipping part of image using two filter streams and overlay
1er janvier 2016, par John DeereI am trying vertically and horizontally flip the row with data & time and speed of my video from the Car Dashcam installed vice versa. The command
ffmpeg -i \20160101_123857_3043.mp4 -vf "split [main][tmp] ; [tmp] crop=1080:39:0:1040,vflip,hflip [flip] ; [main] crop=1080:1941:0:0 [flip] overlay" out.mp4
return Unable to parse graph description substring : "overlay=40:0"
What’s wrong in the command ? The video is the Full HD 1920x1080.
