La sauvegarde automatique de canaux SPIP

1er avril 2010, par kent1

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 (...)
Installation en mode ferme

4 février 2011, par kent1

Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)
Keeping control of your media in your hands

13 avril 2011, par kent1

The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".
MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.
MediaSPIP aims to be accessible to as many people as possible and development is based on expanding the (...)

Ffmpeg video output is 0 seconds with correct filesize when uploading to google cloud bucket

22 août 2022, par Turgut

I've made a C++ program that lives in gke and takes some videos as input using ffmpeg, then does something with that input using opengl(not relevant), then finally encodes those edited videos as a single output. Normally the program works perfectly fine on my local machine, it encodes just as I want it to with no warnings or valgrind errors whatsoever. Then, after encoding the said video, I want my program to upload that video to the google cloud storage. This is where the problem comes, I have tried 2 methods for this : First, I tried using curl to upload to the cloud using a signed url. Second, I tried mounting the google storage using gcsfuse(I was already mounting the bucket to access the inputs in question). Both of those methods yielded undefined, weird behaviour's ranging from : Outputing a 0byte or 44byte file, (This is the most common one :) encoding in the correct file size 500mb but the video is 0 seconds long, outputing a 0.4 second video or just encoding the desired output normally (really rare).

From the logs I can't see anything unusual, everything seems to work fine and ffmpeg does not give any errors or warnings, so does valgrind. Everything seems to work normally, even when I use curl to upload the video to the cloud the output is perfectly fine when it first encodes it (before sending it with curl) but the video gets messed up when curl uploads it to the cloud.

I'm using the muxing.c example of ffmpeg to encode my video with the only difference being :

void video_encoder::fill_yuv_image(AVFrame *frame, struct SwsContext *sws_context) {&#xA;    const int in_linesize[1] = { 4 * width };&#xA;    //uint8_t* dest[4] = { rgb_data, NULL, NULL, NULL };&#xA;    sws_context = sws_getContext(&#xA;            width, height, AV_PIX_FMT_RGBA,&#xA;            width, height, AV_PIX_FMT_YUV420P,&#xA;            SWS_BICUBIC, 0, 0, 0);&#xA;&#xA;    sws_scale(sws_context, (const uint8_t * const *)&amp;rgb_data, in_linesize, 0,&#xA;            height, frame->data, frame->linesize);&#xA;}&#xA;

rgb_data is the data I got after editing the inputs. Again, this works fine and I don't think there are any errors here.

I'm not sure where the error is and since the code is huge I can't provide a replicable example. I'm just looking for someone to point me to the right direction.

Running the cloud's output in mplayer wields this result (This is when the video is the right size but is 0 seconds long, the most common one.) :

Edit : Since the code runs on a VM, I'm using xvfb-run ro start my application, but again even when using xvfb-run it works completely fine on when not encoding to the cloud.

Using youtube-dl and ffmpeg (or vlc) to transcode a YouTube live stream to rtsp rtmp udp rtp

11 septembre 2018, par Matthew Wachter

I’m trying to use youtube-dl to transcode the YouTube NASA ISS live stream (or any YouTube stream) to rtmp or rtsp. I think I have the right command but for some reason I can’t get anything to connect to my newly transcoded stream.

Here’s the command I’m using :

youtube-dl -f best "https://youtu.be/RtU_mdL2vBM" -o - | ffmpeg -re -f mp4 -i pipe:0 -ar 44100 -f flv rtmp://localhost:1935/test/test'

The command appears to work and I see information about the stream files opening from YouTube but when I use the command below, vlc reports that it is unable to connect to the stream.

vlc rtmp://localhost:1935/test/test

If I use this next command the stream plays correctly in vlc and I can see that the youtube-dl part is functioning.

youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc -

or simply just

vlc -vvv https://youtu.be/RtU_mdL2vBM

So it seems that ffmpeg is the issue or maybe I need a streaming server between the transcode and my desired destination (vlc or TouchDesigner). I’ve also tried using vlc in place of ffmpeg/youtube-dl :

vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

youtube-dl -o - "https://youtu.be/RtU_mdL2vBM" | vlc - --sout '#transcode{vcodec=h264,vb=800,acodec=none}:rtp{sdp=rtsp://:554/test}'

and view with

vlc rtsp://localhost:554/test

Unfortunately I haven’t been able make either of those methods work. I can’t even see the stream in vlc if I try to duplicate it like this :

vlc -vvv https://youtu.be/RtU_mdL2vBM --sout '#duplicate{dst=display,dst="#transcode{vcodec=h264,vb=800,acodec=none}:rtp{,sdp=rtsp://:554/test}"}'

Any advice would be greatly appreciated. Thanks !

EDIT
Here’s the ffmpeg log as requested. The program continues to run without error so I interrupted it after a about a minute.

gstreamer : Internal data error, in appsink "pull-sample" mode

9 mai 2018, par Amir Raza

I am getting Internal data error, in appsink .
My application is to read .yuv data , encode and write to a buffer.

I have accomplished the writing it file but when i changed the code to write it buffer it giving error.
Its only able to write only single packet (188bytes).

Output of program :

 (ConsoleApplication6.exe:14432): GStreamer-WARNING **: Failed to load plugin 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll': 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\libgstopenh264.dll': The specified procedure could not be found.
