• how to solve ffmpeg video merging complain about parameters mismatching

  22 septembre 2019, par mohammad rostami siahgeli

  I’m trying to concatenate an intro video to a main video. Here’s my command :

  ffmpeg -i C:\Temp\intro.mp4 -i C:\Temp\main.mp4 -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" -map "[outv]" -map "[outa]" C:\Temp\output.mp4

  When I run this command in cmd, I get the following error :

  I’m not a video ninja. I know parameters are different, but I have no idea after hours of search on how to solve this. A lot of online video services concatenate these two videos and give me a reasonable result. They have a GUI though. I need to do it in code, so that I can automate it.

  How can I solve these errors ?

  Update : This is the second error :

• can't record docker selenium with ffmpeg and ubuntu 18

  1er janvier 2019, par Alex028502

  I have a script that starts a selenium/standalone-chrome container, starts recording with ffmpeg, and runs the selenium tests. However, it is not working with ubuntu 18, possibly because of the ffmpeg version (3.4.4 instead of 2.8.15).

  I have broken down the problem into a couple commands which work fine in ubuntu 16 but not ubuntu 18 :

  start selenium container in terminal #1

  docker run --network=host --shm-size=2g -e SCREEN_WIDTH=1920 -e SCREEN_HEIGHT=1080 selenium/standalone-chrome:3.141.59-antimony

  start recording in terminal #2

  rm -f test.mp4
  
  # :99 seems to be the default for the selenium container
  
  ffmpeg -f x11grab -video_size 1920x1080 -i :99 -codec:v libx264 -r 4 test.mp4

  and I get something that looks like this

  frame=    2 fps=0.1 q=-1.0 Lsize=       2kB time=00:00:00.25 bitrate=  75.9kbits/s dup=0 drop=413 speed=0.0165

  the time stays at 0, and then goes up to 25msec when I stop it.

  On the other hand, if I just start regular screen buffer in terminal #1

  Xvfb :99 -screen 0 1920x1080x24

  and run the same thing as above in terminal #2, everything works

  Also, I am pretty sure that the above ffmpeg command worked in ubuntu 16, with ffmpeg-3.

  So to summarise when the above ffmpeg command seems to work :

                     | ubuntu 16 (ffmpeg 3) | ubuntu 18 (ffmpeg 4)
  
  just start Xvfb    | works                | works
  
  selenium container | works                | DOES NOT WORK

  Any ideas ?

• ffmpeg doesn't accept input in script

  21 octobre 2022, par Eberhardt

  this is a beginner's question but i can't figure out the answer after looking into it for several days :

  


  I want ffmpeg to extract the audio portion of a video and save it in an .ogg container. If i run the following command in terminal it works as expected :

  


  ffmpeg -i example.webm -vn -acodec copy example.ogg


  


  For convenience, i want to do this in a script. However, if i pass a variable to ffmpeg it apparently just considers the first word and produces the error "No such file or directory".

  


  I noticed that my terminal escapes spaces by a \ so i included this in my script. This doesn't solve the problem though.

  


  Can someone please explain to me, why ffmpeg doesn't consider the whole variable that is passed to it in a script while working correctly when getting passed the same content in the terminal ?

  


  This is my script that passes the filename with spaces escaped by \ to ffmpeg :

  


  #!/bin/bash

titelschr=$(echo $@ | sed "s/ /\\\ /g")
titelohne=$(echo $titelschr | cut -d. -f 1)
titelogg=$(echo -e ${titelohne}.ogg)  

ffmpeg -i $titelschr -vn -acodec copy $titelogg


  


  Thank you very much in advance !
