Support de tous types de médias
10 avril 2011Contrairement 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) (...)

Get decibel array from audiofile
16 avril 2020, par R. AdangI am creating a React Native app and want to show list of decibel numbers based on an audio file.
so the goal is -> input : audiofile(mp3,wav etc) output : array of decibels for samples with X milliseconds. I know about
FFMPEG
, but I do not know how to use it to get the array. I see there is a waveform option, but this returns a png instead of the volume data.

lavu : Drop FF_API_GET_CHANNEL_LAYOUT_COMPAT cruft
5 septembre 2015, par Hendrik Leppkeslavu : Drop FF_API_GET_CHANNEL_LAYOUT_COMPAT cruft
FATE refs changed to accomodate for the new default behavior of the function.
Numbers are now interpreted as a channel layout, instead of a number of channels. -
OpenCV 3.0.0 make error with FFMPEG
24 mars 2016, par Ujjwal AryanI have been using OpenCV for a while. However I have recently changed my system to a cluster where I do not have any admin permission. The problem is like this :
In my home folder, I installed FFMPEG (latest stable version available on ffmpeg site). I installed it in $HOME, and so in $HOME/lib there are the library files installed. For more information I compiled FFMPEG with following options :
./configure --prefix=$HOME --enable-shared --enable-pic
I then downloaded the latest stable version of OpenCV 3.0.0 and configured it using ccmake. When I try to
make -j8
, it gives me the following error.Scanning dependencies of target opencv_videoio

make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1
make[2]: *** Waiting for unfinished jobs....However without ffmpeg support it works fine. However I need ffmpeg support due to the nature of my work.
In trying to resolve the problem, I tried installing OpenCV 2.4.11 but it also gave this error. The latest GIT version does not give me this error but rather an error a part of which goes like this
Linking CXX shared library ../../lib/libopencv_highgui.so /usr/bin/ld: /home/matheus/ffmpeg_build/lib/../lib/libavcodec.a(avpacket.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used
I have pasted the above error from another unresolved question online and so the folder names are different but the relocation error is exactly the same.
In trying to resolve the problem I searched and found the following link http://answers.opencv.org/question/12597/build-problems-for-opencv-241-with-ubuntu-1204-lts/
However, one of the answers over there mentioned changing some lines in cap_ffmpeg_impl.hpp file. I tried doing that but either i am not able to do it correctly or something else is going wrong and it is not working. Exact line numbers and exact changes are not mentioned and so I am having difficulty changing things and being sure.
I am using Fedora 19 (Schrodinger Cat) as the operating system I hope the details of my question are clear and I hope that the community would oblige me with a good response.
