Guys I am a noob apologies if this has been asked..

I have over 900 files to concatenate and am using following command:

ffmpeg -f concat -i files.txt -vf scale=1080:-1 -vcodec mpeg4 -b:v 1000k
output.mp4

I Created a txt list(files.txt) with names of the videos (video-1.h264 - to
video-943.h264)

the response I get is "[concat @ 0000000000e967e0] Line 1: unknown keyword
'video-1.h264'
files.txt: Invalid data found when processing input

I am executing ffmpeg in the video directory... so don't need full path to
videos, right?

what am I doing wrong?

besides that you can't concat h264 that way "-i" expects a video file, you need some shell scripting - but as said: h264 is not something you can concact that way

just read https://trac.ffmpeg.org/wiki/Concatenate
