  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.

  • Duplicated frames when mering multiple videos with xfade filter (ffmpeg)

    25 février 2021, par tjk

    I'm stuck with merging multiple videos with audio. This used to work on most videos I merged before but with some videos, I get the "More than 1000 frames duplicated" warning, and the output video is broken (some videos won't play, just static picture and the sound is misaligned).

    


    All videos are in the same format afaik. The only difference I see is that some are "yuvj420p(pc)" and most are "yuv420p". But I tried merging without those with "yuvj420p(pc)" and it didn't help.

    


    Already tried adding "-vsync vfr", didn't help too.
Interestingly — if I remove the second or the last input video, no warning is given and it all works.

    


    The command I use :

  • building c++ code into a shared library

    11 avril 2016, par gaurav

    I have some c++ code which i use as shared library in a java application.My c++ code uses some libraries like ffmpeg and boost. and ffmpeg libraries in turn depend on libx264. my first question is - can i build my c++ into a "fat" shared library which contains all the symbols from all libraries used so that on a new machine if i just copy the fat .so file everything works.
    If thats not possible then can you help me fix my current build process. This is what i am doing currently -

    1)on a local VM(ubuntu 64) i compile ffmpeg code using -fPIC flag and install h264 and boost using apt-get commands.
    2) on the same VM i compile my code using make file which looks like this-

    INCLUDES =   -I/opt/ffmpeg/include -I/usr/lib/jvm/java-7-openjdk-   amd64/include -I/usr/lib/jvm/java-7-openjdk-amd64/include/linux
    

    
LDFLAGS =   -L/home/ubuntu/ffmpeg_shared
    

    
LIBRARIES = -lavformat -lavcodec -lswscale -lavutil -lpthread  -lx264 -lboost_system -lboost_thread -lboost_chrono 
    

    
CC = g++ -std=c++11 -fPIC
    

    
all:clean final
    

    
final:Api.o ImageSequence.o OverlayAnimation.o Utils.o ImageFrame.o 
    
$(CC)  -o final.so Api.o ImageSequence.o OverlayAnimation.o Utils.o  ImageFrame.o $(LDFLAGS) $(LIBRARIES) -shared

    3) on a new machine where java app will run. i install h264 and boost using apt-get commands and copy ffmpeg’s compiled library files to /usr/local/lib.

    4) copy the final.so file to this new machine. but when the java code tries to use the final.so file i see it tries to use wierdly named files. for example - it tries to find libavcodec.so.57 , libavformat.so.57 etc. to fix this i just created a copy of these files ie libavcodec.so copied to libavcodec.so.57.

    5)But these ffmpeg libraries in turn uses a differently named lib264.so file. on my new machine the apt-get command for x264 installed a file named libx264.so.148 but one of ffmpeg libraries is searching for file libx264.so.142 even if i rename this libx264.so file i get new errors where ffmpeg libraries tries to call libx264’s methods which has these numbers attached.

    6) at this time the only working option for me is to bring the c++ code on every new machine and build final.so file locally. this is something i want to avoid since i want to distribute the .so file along with jar file to my clients which they can easily use without having to build and install stuff.

  • Wrong second count for blackdetect filter in ffprobe

    10 avril 2016, par Jabb

    I issue this command on a 8 minutes 20 seconds video in order to detect blackframes.

    root@ubuntu:/home/hts# ffprobe -f lavfi -i "movie=test.ts,blackdetect[out0]" -show_entries tags=lavfi.black_start,lavfi.black_end -of default=nw=1

    I am expecting to get proper seconds back from ffprobe indicating where the blackframes are.

    Instead I receive very very high numbers.

    I need to mention that I cut this video from the end of a larger stream using tail. The stream is configured to add a keyframe every 0.5 seconds. Could this be the reason ? And how could I cope with this ?
