  • Les vidéos

    21 avril 2011, par

    Comme 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 (...)

  • Avconv : Select german stream not highest quality one

    6 novembre 2017, par mblaettermann

    I am converting some input stream from my DVB S2 Card to RTMP.

    Everything works fine after switching to recent avconv and x264 :)

    The only thing I couldn’t find out is, how do I select the right audio stream ?

    The source sometimes has up to 6 audio tracks. Avconv automatically chooses the one with the highest bitrate. However I want to select the "ger" one :

    Here are the streams of ARTE german/french TV Channel for example :

    Input #0, mpegts, from 'http://192.168.1.50:9981/stream/channelid/1035':
    
  Duration: N/A, start: 19083.694722, bitrate: 15576 kb/s
    
  Program 1
    
    Stream #0.0[0xa8], 127, 1/90000: Video: mpeg2video (Main), yuv420p, 544x576 [PAR 32:17 DAR 16:9], 1/50, 15000 kb/s, 25 fps, 90k tb50 tbc
    
    Stream #0.1[0x70](fre), 204, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 192 kb/s
    
    Stream #0.2[0x71](ger), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
    Stream #0.3[0x72](eng), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
    Stream #0.4[0x73](qaa), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
    
  No Program
    
    Stream #0.5[0x3b], 126, 1/90000: Audio: mp1, 0 channels, s16p

    libav Docs are really not that helpful. Who does now the right syntax ?

    EDIT : I found the -map option : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20use%20-map%20option But it is not possible to map by name ? Only by index ?

    Maybe I need to use avprobe then, to find the corrent stream index for "ger".

  • Streaming live video from Windows to Android with FFmpeg

    29 avril 2018, par Alan Daniels

    I am capturing live video on a Windows PC and encoding it with FFmpeg. I can stream the content live to another PC using rtsp://[dest_ip:port]/live.sdp as FFmpeg’s output on the sender and using ffplay -rtsp_flags listen rtsp://[dest_ip:port]/live.sdp on the receiver. However, I have to run FFplay before starting the sender. Also, VLC cannot play the rtsp path :

    main debug: net: connecting to 127.0.0.1 port 5555
    
main error: connection failed: Connection refused by peer
    
access_realrtsp error: cannot connect to 127.0.0.1:5555
    
access_realrtsp debug: could not connect to: 127.0.0.1:5555/live.sdp

    However, FFplay and VLC can play something like ffplay rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov.

    On the Android side, I am using the Media API which can play content from a URI. It works with HTTP and RTSP (as far as I know).

    I’ve looked at FFmpeg’s streaming guide : https://trac.ffmpeg.org/wiki/StreamingGuide, but I am still confused about the difference between my path rtsp://[dest_ip:port]/live.sdp and rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov.

    Do I need a streaming server in order to have my content accessible by URI ? Any recommendations since FFserver is depreciated ?
