• How To Resize, Reduce a Video to a Specific Size and Quality Ubuntu Linux using ffmpeg


    This is a common issue when e-mailing or uploading video files. One note is that you should make the filesize you choose below about 20% smaller than you need. For example I took a 219MB video and told it to be 20M. The resulting file was still about 21.9M but it was OK when I said 18M and was barely below the 20M size. ffmpeg is our friend here, just use this command: Change the -fs 100Mto the size you want eg. 20M, 500M Chan........
  • ffmpeg how to cut certain parts of video out


    With ffmpeg it literally takes out what you want so you can use it later. Eg. below -ss means starting time is 16 minutes and 30 seconds and -to means extract until 17 minutes and 23 seconds -i = the input file output file = CCME-flash-and-2-phone-setup-final.mp4 ffmpeg -i CCME-flash-and-2-phone-setup.mp4 -ss 00:16:30 -to 00:17:23 -c copy CCME-flash-and-2-phone-setup-fin........
  • ffmpeg how to concat and join two video clips


    This normally works but if not use my mencoder solution if the output video does not play past the joined time. the contents of list.txt need to look like this: file somefile.mp4 file somefile2.mp4 then run ffmpeg ffmpeg -f concat -i list.txt -c copy CME-2-router-dial-peer-final.mp4 The result is almost instant joining since there is no video processing since we are........
  • mencoder instead of ffmpeg to join or concatenate video files with different audio streams


    The problem for me is that Ihad two videos with different types of audio streams. ffmpeg would join them but they would not play past the point of the join. So Iused mencoder like below and it joined the audio and made them both mp3 streams and it worked! -oac mp3lame specifies the audio to be convered into an mp3 stream using the lame codec. after the oac the two files are the ones to be joined. the -o is the name of the outp........
  • How To Replace Audio Track of Video using ffmpeg


    A very common use case is that you don't want to waste time using a video editor that requires you to open it up and manually import the video clip and audio clip, then manually delete the old audio track and import the video and new audio. That's too much work and time since we don't want to go through the hassle. ffmpeg is our solution, all we have to do is specify 3 variables and we're done! -i Windows2019-Server-Noaudio.mp4 is our in........
  • h264 DVR security camera footage cannot be played


    This is not just a Linux issue but a general issue most software or hardware players cannot play the resulting exported/backed up format of .h264 from DVR security camera footage for some silly reason.

  • ffmpeg how to watermark and concatenate in one command


    If you were in my boat you were frustrated that you had to double encode, eg. one separate encode for watermark and a separate from concat and it's not easy to figure out this with ffmpeg on your own. However it is a nice way to save time! ffmpeg -i file1.mp4 -i file2.mp4 -i file3.mp4 -i watermark.png -filter_complex "[0:v]setpts=PTS-STARTPTS[v0]; [1:v]setpts=PTS-STARTPTS[v1]; [2:v]setpts=PTS-STARTPTS[v2]; [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][aout]; [v][3:........
  • ffmpeg trouble concatenating similar but different files


    When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right. Solution for me: My example uses 3 videos in total so "n=3" and a=1 to include audio. ffmpeg -threads 12 -i file1.mp4 -........

    This is very annoying that ffmpeg is missing from Linux Mint!

However on Linux Mint 17 I was able to use a Ubuntu PPA and sucessfully install ffmpeg! https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media Adding this PPA to your system........
