Simple Concatenation two files

[javeedrahman]

Hi,

I am trying to concatenate two files one file which is already concat using CircleCrop here is he code. After concatenating video length was more than 15 seconds from the actual video length of two files. Last 15 seconds got stuck.

Please looks at the command and if it's wrong correct me.

../ffmpeg -loglevel debug \
  -i /home/procserverjh/opengl/fhd1.mp4 \
  -i /home/procserverjh/opengl/fhd2.mp4 \
  -filter_complex " \
    [0:v]split[v000][v010]; \
    [v010][1:v]gltransition=duration=1:source=/home/procserverjh/opengl/gl-transitions-master/transitions/CircleCrop.glsl[vt0]; \
    [v000][vt0]concat=n=2[outv]" \
  -map "[outv]" \
  -c:v libx264 -profile:v baseline -preset slow -movflags faststart -pix_fmt yuv420p \
  -y /home/procserverjh/opengl/fhdoutcirclecli5.mp4

It will help to see the verbose output from the command.

@transitive-bullshit Sure I have attached the verbose output here.
Total Three files.
I have concat first two files, then i have concat third mp4 with first two files output.mp4.

Aye, nothing really stands out for me in that log and unfortunately I don't have the time these days to help debug.

Hopefully another member of the community will be able to help.

Okay thank you @transitive-bullshit ,

Could you please just confirm that the command which I am running is correct? and Is there any conflict when concatenating higher resolution?

Reducing video bitrate fixes it for some files but not always.
