    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • avcodec/omx : Fix handling of fragmented buffers

    avcodec/omx : Fix handling of fragmented buffers
    

    See https://trac.ffmpeg.org/ticket/7687

    If an encoded frame is returned split over two or more
    IL buffers due to the size, then there is a race between
    whether get_buffer will fail, return NULL, and a truncated
    frame is passed on, or IL will return the remaining part
    of the encoded frame.
    If get_buffer returns NULL, part of the frame is left behind
    in the codec, and will be collected on the next call. That
    then leaves a frame stuck in the codec. Repeat enough times
    and the codec FIFO is full, and the pipeline stalls.

    A performance improvement in the Raspberry Pi firmware means
    that the timing has changed, and now frequently drops into the
    case where get_buffer returns NULL.

    Add code such that should a buffer be received without
    OMX_BUFFERFLAG_ENDOFFRAME that get_buffer is called with wait
    set, so we wait for the remainder of the frame.
    This code has been made conditional on the Pi build in case
    other IL implementations don't handle ENDOFFRAME correctly.

    • [DH] libavcodec/omx.c
  • linux ffmpeg Live streaming cannot connect to another PC

    9 juin 2019, par Tae-Yeong

    I’m set ffserver and ffmpeg streaming code in the linux console terminal.

    ffserver => ffserver -f ./ffserver.conf (terminal 1)

    ffmpeg => ffmpeg -r 15 -s 640x480 -f video4linux2 -i /dev/video0 http://mylocalhostip:8090/feed1.ffm (terminal 2)

    It was working success in the localhost.
    But It could not connect other PC or Mobile.
    Firewall set disable.

    My desktop and mobile have a normal Internet connection.

    I want to Live-Streaming connect other PC or Mobile.
    How can I do ?

    Hardware = LattePanda
    OS = Ubuntu 16.04

    < ffserver.conf >

    HTTPPort 8090

    bind to all IPs aliased or not

    HTTPBindAddress 0.0.0.0

    max number of simultaneous clients

    MaxClients 1000

    max bandwidth per-client (kb/s)

    MaxBandwidth 10000

    Suppress that if you want to launch ffserver as a daemon.

    NoDaemon

       <feed>
       File /tmp/feed1.ffm
       FileMaxSize 100M
       </feed>
       <stream>
       Feed feed1.ffm
       Format swf
       VideoCodec flv
       VideoFrameRate 15
       VideoBufferSize 80000
       VideoBitRate 100
       VideoQMin 1
       VideoQMax 5
       VideoSize 640x480
       PreRoll 0
       Noaudio
       </stream>
       <stream>
       Format status
       ACL allow localhost
       ACL allow 121.172.0.0 121.172.0.255 (my desktop Ip range)
       </stream>

    I expect to output of My WebCam Screen, but the actual output timeout.

    My desktop OS is Window10. And Mobile OS is Android.

  • How to deal ffplay bein too slow playing iPhone's videos ?

    21 janvier 2019, par Mikhail T.

    Trying to play a 3840x2160 video recorded by an iPhone 7 (@30fps), I get frequent pauses — in the video, music keeps playing.

    This happens both in firefox and when ffplay is invoked to play the file directly — from command-line. The CPU is a dual E6700 @3.20GHz — not super fast, but it should be able to play smoothly, shouldn’t it ? Video is Intel’s "series 4" integrated chipset — again, not a speed-daemon, but it should be adequate... Support for Intel’s VA API is included.

    I build ffmpeg-4.1 from source using FreeBSD port. As you can see, the port has a maddening amount of options — including several different ones for the 264-codec.

    Any suggestions for improving the decoding speed to the point, where it is watchable by a human ? Thank you !
