Stream specifier

[Vladimir]

Summary of the bug:
I'm trying to join the video files with different streams count

Here is my code:

target_width=720
target_height=480
target_aspect_ratio=$target_width/$target_height

./ffmpeg -y -i mp4.mp4 -i ogv.ogv -i ogv2.ogv -vcodec ppm -filter_complex "[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1:unsafe=1 [v] [a]" -s '1280x1080' -b:v '512K' -b:a '128K' -strict -2 -c:v libx264 -preset ultrafast -map [v] -map [a] -r 30 outtmp.mp4
./ffmpeg -i outtmp.mp4 -s $target_width'x'$target_height -vf "scale=iw*sar:ih , pad=max(iw\,ih*($target_aspect_ratio)):ow/($target_aspect_ratio):(ow-iw)/2:(oh-ih)/2" -aspect $target_width':'$target_height -strict -2 777.mp4
rm -f outtmp.mp4

In console i get the following error:

Stream specifier ':1' in filtergraph description [0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1:unsafe=1 [v] [a] matches no streams.

How can I detect that video file does not have stream?

You need to include an unscripted command and the complete console output. Then we can attempt to duplicate the issue and determine if this is a bug or not.

Please use code block to format your command and output:

Here is code of bash file

target_width=720
target_height=480
target_aspect_ratio=$target_width/$target_height

./ffmpeg -y -i mp4.mp4 -i ogv.ogv -i ogv2.ogv -vcodec ppm -filter_complex "[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1:unsafe=1 [v] [a]" -s '1280x1080' -b:v '512K' -b:a '128K' -strict -2 -c:v libx264 -preset ultrafast -map [v] -map [a] -r 30 outtmp.mp4
./ffmpeg -i outtmp.mp4 -s $target_width'x'$target_height -vf "scale=iw*sar:ih , pad=max(iw\,ih*($target_aspect_ratio)):ow/($target_aspect_ratio):(ow-iw)/2:(oh-ih)/2" -aspect $target_width':'$target_height -strict -2 777.mp4
rm -f outtmp.mp4

I need to know how to join video files with different stream count.
Video files are attached.
Thanks in advance.

Are you reporting a bug?
If yes, please explain why you believe FFmpeg should act differently.

[Vladimir]

I'm not saying that is a bug. I need help to solve the problem.
