  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une 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 (...)

  • Autostart Ffmpeg when I connect to Red5 ? [on hold]

    6 novembre 2013, par Alex Scott

    I have setup Red5 media server on my server along with ffmpeg and I can connect to my Red5 server using Flash Media Encoder and I can view my stream within my website.

    My problem is that I know you can now use ffmpeg to convert the stream into segmented files and create the m3u8 playlist.

    Unfortunately, my stream is not live 24/7, only on weekends, so I want to know if it is possible to automatically start the ffmpeg decoding process when the stream is active and end it when the stream finishes ?

    The website which I am using this on is Official Sound FM.

    Thanks in advance for helping me with this matter and if anyone should require my services to setup a similar streaming service with them, please don't hesitate to ask me.

  • rtsp timeout av_read_frame

    30 novembre 2012, par user1175197

    I am using ffmpeg to play an RTSP stream. I have a loop like

        while (av_read_frame(formatContext, packet)>=0)
    
    {
    
      doWork();
    
    }

    I can watch the stream as long as there is something moving in front of the camera. But whenever the view is stable the above function returns EOF as I checked with av_strerror. Any ideas why and how to fix it ?

    thanks

  • FFmpeg encoding through h264_qsv : pts < dts

    29 décembre 2023, par Mario

    I'm modifying a portion of code that encodes input frames in an output mp4 file via the h264 software encoder which works quite well. Most of the code comes from https://ffmpeg.org/doxygen/6.0/mux_8c-example.html.

    &#xA;

    I changed the "working" code to use the h264_qsv hardware accelerated encoder. After a lot of work the new code produces h264 encoded frames. For testing purpose I can write them with

    &#xA;

    &#xA;

    fwrite(pkt->data, pkt->size, 1, fout)

    &#xA;

    &#xA;

    and mpv displays frames correctly (with some warnings).

    &#xA;

    When I use regular :

    &#xA;

    &#xA;

    av_interleaved_write_frame(fmt_ctx, pkt)

    &#xA;

    &#xA;

    (as from previously working code) returns an error and on stderr :

    &#xA;

    &#xA;

    [mp4 @ 0x7f82a80b3b40] pts (-1574122160956548608) < dts&#xA;(1574122160956547584) in stream 0

    &#xA;

    &#xA;

    To look for the cause I added the following lines just before av_interleaved_write_frame(). I read that it may be a non-fatal error and so I continue after the errors, but there isn't output.

    &#xA;

    &#xA;

    frame->pts=210
    &#xA;pkt->pts=-1574122160956548608
    &#xA;pkt->dts=1574122160956547584
    &#xA;[mp4 @ 0x7effb40b3b40] pts (-1574122160956548608) < dts (1574122160956547584) in stream 0
    &#xA;...
    &#xA;frame->pts=240
    &#xA;pkt->pts=-1574122160956548608
    &#xA;pkt->dts=1574122160956548096
    &#xA;[mp4 @ 0x7effb40b3b40] pts (-1574122160956548608) < dts (1574122160956548096) in stream 0

    &#xA;

    &#xA;

    I did another test assigning incremental values to pkt->pts and pkt->dts, it works but resulting fps is wrong, and I don't think it is the right solution !

    &#xA;

    Why does the av_interleaved_write_frame(fmt_ctx, pkt) function returns an error with h264_qsv encoder ? Who should set pkt->pts and pkt->dts ?
