ffmpeg video concate not working when one video is generated from a single image
16 décembre 2017, par Sidwhat I am doing is generating a video of 5 secs from a single image using FFmpeg.
for that I’m using the following command :
-loop 1 -i image.jpg -c:v libx264 -t 5 -pix_fmt yuv420p -crf 25 -s 1280x720 Out.mp4.
Now I want to concatenate this video with another one.
I am able to do this for other videos with the following command
-y -i input1.mp4 -i input2.mp4 -strict experimental -filter_complex [0:v]scale=1280x720,setsar=1:1[v0][1:v]scale=1280x720,setsar=1:1[v1] ;[v0][0:a][v1][1:a]
concat=n=2:v=1:a=1 -ab 48000 -ac 2 -ar 22050 -s 1280x720 -r 30 vcodec
mpeg4 -b 2097k output.mp4But when I join the video generated from the image, the videos do not join as the second input does not have an audio because it is generated from the image.So is there any way to join these two videos using
-filter_complex
in FFmpeg ? -
