  • How to combine 2 videos using either NReco ffmpeg ConvertMedia or just ffmpeg command line ?

    11 octobre 2016, par M. Ilchuk

    We have 2 videos : video1.webm and video2.webm.
    How to combine these two and get output.mp4 which contains video from video1.webm and audio from video1 and video2 ?

    Example :

    video1(audio1 in video1) + video2(audio2 in video2) = outputVideo(video1 + audio1 +audio2)

    image example

    ffmpeg -i 1.webm -i 2.webm

  • android ffmpeg halfninja av_open_input_file returns -2 (no such file or directory)

    20 janvier 2012, par cdavidyoung

    I have built ffmpeg for Android using the code and method described at

    https://github.com/halfninja/android-ffmpeg-x264

    using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at

    FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

    but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file :" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.

  • FFmpeg can 'encode' to mp3, but will not accept an 'input' mp3

    21 novembre 2011, par Jonathan Coe

    FYI : Fedora 8 running on Amazon EC2...

    Having a difficult time with FFmpeg doing a (what should be pretty simple) conversion. I can get FFmpeg to encode an mp3 file from an m4a file using the following :

    ffmpeg -i file1.m4a -acodec libmp3lame -ab 160k file2.mp3

    However, I cannot get it to to convert an mp3 -> mp3, it responds with "Unknown Format" using the following :

    ffmpeg -i file1.mp3 -acodec libmp3lame -ab 160k file2.mp3

    I get the following command string :

    FFmpeg version UNKNOWN, Copyright (c) 2000-2008 Fabrice Bellard, et al.

file1.mp3: Unknown format

    Any help would be hugely appreciated !

    Edit for clarity :
    The input file is in /ebs/queue/input.mp3 and the output is /ebs/converted/output.mp3
