    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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.

  • ffmpeg unable to find encoder 'libvorbis'

    15 juillet 2014, par scientiffic

    I’m unable to transcode a video file to webm because my machine isn’t able to find libvorbis. When I run the following command :

    ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360  -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm

    I get the error

    Unknown encoder 'libvorbis'

    I already have libvorbis installed on my machine, though (When I try "brew install libvorbis, it tells me : Warning : libvorbis-1.3.3 already installed).

    How can I solve this problem ?

    Here is the full log :

    ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360  -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm
