  • FFMpeg Concatenation Filters : Stream specifier ':0' in filtergraph matches no streams

    7 février 2017, par Anthony Eden

    I am developing an application that relies heavily on FFMpeg to perform various transformations on audio files. I am currently testing my FFMpeg configuration on the command line.

    I am trying to concatenate multiple audio files which are in different formats (Primarily MP3, MP2 & WAV). I have been using the official TRAC documentation (https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join%2C%20merge)%20media%20files#differentcodec) to help me with this and have created the following command :

    ffmpeg -i OHIn.wav -i OHOut.wav -filter_complex '[0:0] [1:0] concat=n=2:a=1 [a]' -map '[a]' output.wav

    However, when I run this on Mac OS X using version 2.0.1 of FFMpeg, I get the following error message :

    Stream specifier ':0' in filtergraph description [0:0] [1:0] concat=n=2:a=1 [a] matches no streams.

    Here is my full output from the terminal :

    ~/ffmpeg -i OHIn.wav -i OHOut.wav -filter_complex '[0:0] [1:0] concat=n=2:a=1 [a]' -map '[a]' output.wav

Stream specifier ':0' in filtergraph description [0:0] [1:0] concat=n=2:a=1 [a] matches no streams.

    I do not understand why this does not work. FFMpeg shows that the streams 0:0 and 1:0 exist in the source files. The only other similar problems online have surrounded the use of the single quote in Windows, however testing of this confirm it does not apply to my Mac command line.

    Any help would be much appreciated.

  • extracting h264 raw video stream from mp4 or flv with ffmpeg generate an invalid stream

Unsupported codec with id 0 for input stream 2

    to get rid of the extra streams ( I only needs the video) I used the following ffmpeg command line :

    ffmpeg -i test.flv -map 0:0 -vcodec copy -an -f h264 test.h264

    The new stream is unreadable by any player including ffplay and gives an error with ffprobe :
    test.h264 : Invalid data found when processing inputq= 0B f=0/0

    Any body have an idea about what am I doing wrong ?

    I also tried simpler youtube command line :

    ffmpeg -i test.flv -vcodec copy -an test.h264

    if I use another format (avi for example) :

    ffmpeg -i test.flv -vcodec copy -an test.avi

    the output video is valid.

    If I transcode the video

    ffmpeg -i test.flv -an test.h264

    the output is also valid

    Any suggestions ?
