La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

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 :
static int opt_input_file(OptionsContext *o, const char *opt, const char *filename)
{
// ...
ic->video_codec_id = video_codec_name ?
find_codec_or_die(video_codec_name , AVMEDIA_TYPE_VIDEO , 0)->id : CODEC_ID_NONE;
ic->audio_codec_id = audio_codec_name ?
find_codec_or_die(audio_codec_name , AVMEDIA_TYPE_AUDIO , 0)->id : CODEC_ID_NONE;

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()

Using FFMPEG with Powershell
19 mai 2017, par CaulenI am using Windows Server Edition 2012 and am very new to using Powershell. Basically, I am trying to convert a bunch of video files that are in a directory to .flv. The code I am using is this :
$inProcessPath = "E:\Random Videos\In Process\$env:username\"
$oldVideos = Get-ChildItem -Include @("*.mp4", "*.avi", "*.divx", "*.mov", "*.mpg", "*.wmv", "*.mkv") -Path $inProcessPath -Recurse #gets all of the videos
cd "E:\FFMPEG\bin\"
foreach ($oldVideo in $oldVideos) {
$newVideo = [io.path]::ChangeExtension($oldSong.FullName, '.flv')
.\ffmpeg.exe -i $oldVideo -y -async 1 -b 2000k -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast $newVideo
}Whenever I run this I don’t get any error messages but ffmpeg doesn’t run either. I’m sure I’m overlooking something but have no idea what that could be. I’ve searched the website and compared code to others and still have no idea.
Any help would be very much appreciated.
