Les tâches Cron régulières de la ferme

1er décembre 2010, par kent1

La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

android ffmpeg halfninja av_open_input_file returns -2 (no such file or directory)

20 janvier 2012, par cdavidyoung

I have built ffmpeg for Android using the code and method described at

https://github.com/halfninja/android-ffmpeg-x264

using Ubuntu running in VirtualBox on windows. I then copied libvideokit.so into the Project\libs\armeabi folder of a Windows copy of the provided projects. From there I was able to run the ProjectTest from Eclipse on my Android device. I can see the ffmpeg code being executed but when it gets to the point of opening the input file it gives me the indicated error. I have noticed some discussion of this problem at

FFMpeg on Android, undefined references to libavcodec functions, although it is listed on command line

but the solutions have not helped since the file protocol is enabled in this build and I also tried putting "file :" in front of the filepath to no avail. For completeness I tried setting minimal_featureset=0 to enable all the defaults but this gives me the same error. Below is a snapshot of the logcat from Eclipse showing the output from Videokit with an extra call to LOGE to display the result from av_open_input_file. Any suggestions of things to try would be greatly appreciated.

Overlay filter in LibAV/FFMpeg returns strange (tripled) frame in C

28 juillet 2014, par gkuczera

I tried to make a program, which merges two frames. I use LibAV (libav-win32-20140428) under Windows 7 64 and Visual Studio 2013.
But the result is quite odd.

The filter which was used is Overlay. When I change the graph, to the one, that uses only one stream and add FADE effect, everything works like a charm. But OVERLAY and eg. DRAWBOX give me strange distortion (three frames on one and black and white effect). Here is the code :

static int init_filter_graph(AVFilterGraph **pGraph, AVFilterContext **pSrc1, AVFilterContext **pSink)

{

    AVFilterGraph* tFilterGraph;

    AVFilterContext* tBufferContext1;

    AVFilter* tBuffer1;

    AVFilterContext* tColorContext;

    AVFilter* tColor;

    AVFilterContext* tOverlayContext;

    AVFilter* tOverlay;

    AVFilterContext* tBufferSinkContext;

    AVFilter* tBufferSink;



    int tError;



    /* Create a new filtergraph, which will contain all the filters. */

    tFilterGraph = avfilter_graph_alloc();



    if (!tFilterGraph) {

        return -1;

    }



    { // BUFFER FILTER 1

        tBuffer1 = avfilter_get_by_name("buffer");

        if (!tBuffer1) {

            return -1;

        }

        tBufferContext1 = avfilter_graph_alloc_filter(tFilterGraph, tBuffer1, "src1");

        if (!tBufferContext1) {

            return -1;

        }



        av_dict_set(&amp;tOptionsDict, "width", "320", 0);

        av_dict_set(&amp;tOptionsDict, "height", "240", 0);

        av_dict_set(&amp;tOptionsDict, "pix_fmt", "bgr24", 0);

        av_dict_set(&amp;tOptionsDict, "time_base", "1/25", 0);

        av_dict_set(&amp;tOptionsDict, "sar", "1", 0);

        tError = avfilter_init_dict(tBufferContext1, &amp;tOptionsDict);

        av_dict_free(&amp;tOptionsDict);

        if (tError &lt; 0) {

            return tError;

        }

    }



    { // COLOR FILTER

        tColor = avfilter_get_by_name("color");

        if (!tColor) {

            return -1;

        }

        if (!tColorContext) {

            return -1;

        }

        tError = avfilter_init_dict(tColorContext, &amp;tOptionsDict);

        av_dict_free(&amp;tOptionsDict);

        if (tError &lt; 0) {

            return tError;

        }

    }



    { // OVERLAY FILTER

        tOverlay = avfilter_get_by_name("overlay");

        if (!tOverlay) {

            return -1;

        }

        tOverlayContext = avfilter_graph_alloc_filter(tFilterGraph, tOverlay, "overlay");

        if (!tOverlayContext) {

        }

What do you think is the reason ?

ffmpeg to convert file to webm returns in error

i have a self-recorded file in .ts format and want to convert it to three different formats(.mp4, .ogg and .webm).

for that i use my brandnew debian9 with following commands :

Why i am doing that ? I just play arround with a privat intranet (web-application) to stream my own recorded files on different clients (Smartphone, Tablet, Desktop). Thats also the reason for the different formats (.mp4, .ogg, .webm)

My current problem is : The command to convert it to .webm returns following error :

 /usr/bin/ffmpeg -y -i test.ts -r 25 -b 18550k -bt 22792k -ac 2 -ar 48000 -ab 320k output.webm

[libvpx-vp9 @ 0x557535ba6d00] v1.6.1

Stream mapping:

  Stream #0:3 -> #0:0 (h264 (native) -> vp9 (libvpx-vp9))

  Stream #0:4 -> #0:1 (mp2 (native) -> opus (libopus))

  Stream #0:6 -> #0:2 (dvb_teletext (libzvbi_teletextdec) -> webvtt (native))

Error while opening encoder for output stream #0:2 - maybe incorrect parameters such as bit_rate, rate, width or height

i dont understand the problem, because the convertions to .ogg or .mp4 are workin. So i cannot be a problem with the source-codecs. Does anyone have any idea what my problem might be
