Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -
La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...)

ffmpeg decoding on Android
29 novembre 2013, par KernaldI'm currently trying to use ffmpeg on Android. I built ffmpeg using https://github.com/halfninja/android-ffmpeg-x264 (I adapted it to not use libx264 and build with ndk-r9b, using GCC 4.6). I try to trim an MP4 file. However, the input file fails to open :

I digged into ffmpeg's code, and found the error :

{
// ...
ic->video_codec_id = video_codec_name ?

ic->flags |= AVFMT_FLAG_NONBLOCK;
ic->interrupt_callback = int_cb;
if (loop_input) {
LOGW(
"-loop_input is deprecated, use -loop 1\n"
"Note, both loop options only work with -f image2\n"
);
ic->loop_input = loop_input;
}
/* open the input file with generic avformat function */
err = avformat_open_input(&ic, filename, file_iformat, &format_opts);
if (err < 0) {
print_error(filename, err);
exit_program(1);
}
assert_avoptions(format_opts);
// ...
}As indicated in the logcat,
err
is here equal toAVERROR_INVALIDDATA
. I don't understand the reason however : the mp4 codec is enabled, as far as I can tell. Any hint on how to solve it ?Edit : I added more ffmpeg code. I'm pretty sure it's a codec issue now : ic->video_codec_id is set to
CODEC_ID_NONE
, which causesic
to be set toNULL
and return a failure inavformat_open_input()

Converting Video files in a Azure Webjob with ffMpeg
13 décembre 2016, par Kevin PhiferI’m having trouble using ffMpeg in an Azure webjob.
I found the following article (How to call ffmpeg.exe to convert audio files on Windows Azure ?) and it is exactly what I want to do, however, I cannot get ffMpeg to execute and it gives no error message.
To diagnose the problem, I have boiled it down to its essentials by uploading ffMpeg, a video file to convert, and batch file to run it :
The script in
run.cmd
is simply :del output.mp4
ffmpeg -i screencast.wmv -c:v libx264 -r 15 output.mp4This works on my personal machine, but ran as a webjob I get results below.

Additionally, it was suggested that I run using Kudu console. Still no luck :
Solution :
I ended up needing to run the 32 version of ffMpeg and not the 64 bit. Thanks so much @mathewc ! -
FFMPEG Streaming webcam on Windows 10 to RTP
23 juillet 2019, par gdogg371I am still trying to figure out exactly what I am doing with ffmpeg and dshow. However I am trying to stream a 4k capture device I have, so that I can use this as an IPTV server downstream.
So far I have :
ffmpeg -rtbufsize 2100M -y -loglevel warning -f dshow -i video="Video (00 Pro Capture HDMI 4K+)" -s 3840x2160 -vcodec v410 -f rtp rtp://192.168.1.31:8554
...however this is throwing up the following errors :
C:\Program Files\VideoLAN\VLC>ffmpeg -rtbufsize 2100M -y -loglevel warning -f dshow -i video="Video (00 Pro Capture HDMI 4K+)" -s 3840x2160 -vcodec libx265 -f rtp rtp://192.168.1.31:8554

Can anyone suggest a remedy ?
