Issue when combining 2 video files [after matching the specs]
6 décembre 2015, par RuneBasically I got a .mp4 and a .flv file which I want to concatenate (the .mp4 should be the intro).
So after having asked a previous question regarding this I went ahead and converted the intro video to an .flv with matching specifications of the second video.
First I got the specifications of the second (.flv) video using ffprobe. This was the output :

I then concatenate the ouputted intro file with my main video file using the following command (tmp.txt contains the 2 files) :
-f concat -i tmp.txt -c copy newvid.flvThis produces the following output :

It starts off playing the intro just fine.
However, when the intro is finished the video freezes while the sound of the actual video continues for the entire duration of the video.Thus in conclusion what is lacking is the video of the second vid (the audio is fine).
I’m new at using ffmpeg but I’ve tried my best to solve this, which is why I’m asking for your help.
I’d certainly appreciate if someone could help me out.
