  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

  • Why rtp streaming of a .avi video file fails to be received ?

    14 juillet 2016, par user1914692

    In ffmpeg streamingGuide, it writes :

    ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp://127.0.0.1:1234 &
    
ffplay rtp://127.0.0.1:1234

    I want to use a real video file to replace the artificial signal.
    Then I write the below at terminal A :

    ffmpeg -re -i outputFile.avi -f mulaw -f rtp rtp://127.0.0.1:1234

    it seems it is working :
    The frame information is counting. Here are information on the terminal A at the end :

    frame=  309 fps= 29 q=31.0 Lsize=     931kB time=00:00:10.30 bitrate= 740.8kbits/s     video:922kB audio:0kB subtitle:0 global headers:0kB muxing overhead 1.030813%

    When the frame at terminal A is still counting (not finished), I type the below at terminal B :

    ffplay rtp://127.0.0.1:1234

    But it does not work :
    The error information is :

    [udp @ 0x7fb370001500] bind failed: Address already in useB f=0/0   
    
rtp://127.0.0.1:1234: Input/output error

    Why ?

    [Update 1] Following the instruction from Camille Goudeseune
    I used the foo.sdp
    The input for the ffmpeg terminal is :

    ffmpeg -re -i out.avi -f mulaw -f rtp rtp ://127.0.0.1:1235

    The terminal for ffplay is :

    ffplay -i foo.sdp

    The ffplay terminal shows a lot of error, without images.

  • Running ffplay video within a jframe

    22 juillet 2013, par Optimus Prime

    I wish to play a video in JFrame. I am already using ffmpeg in my project. As I wish to keep the project light, I am not willing to use other frameworks like JMF or other. I know that I can play video using ffplay. But the problem here is ffplay opens the video in new window when I try

    ffplay output.avi

    I wish to put that video within my JFrame, like a player. How can I do this ?

    Request :
    Please ask for any other clarifications, details, and suggest improvements or comment what you find wrong before downvoting or voting to close the question :). I will change it. I am really new to Java, I tried searching this but could not find any possible solution.

    What I tried ? I couln't find anything related to this, so I don't have any code. I am familiar to how to create frames, and can use runtime to ffplay video. But I got no clue how to put that video within my window :(.

    All suggestions are welcome if you can suggest me other methods to play the video. But I haven't use any frameworks other than ffmpeg. And do not wish to make the application heavier. So it would be more helpful if it can be achieved using ffplay.

    3 septembre 2013, par rajat

    I have a file sequence of format test2#.iff, and i want to convert this sequence to a video, i have tried following commands :

    ffmpeg -f IFF -r 25 -start_number 75 -i "test2%d.iff" -vcodec libx264 test2.mp4
    
Error: test2%d.iff: No such file or directory
    

    
ffmpeg -f image2 -r 25 -start_number 75 -i "test2%d.iff" -vcodec libx264 test2.mp4
    
Error: [image2 @ 00000000002ee220] Could not find codec parameters for stream 0 (Video: none): unspecified size Consider increasing the value for the 'analyzeduration' and 'probesize' options test2%d.iff: could not find codec parameters

    I also have tried various codecs but it gives me same errors, can any of you please shed some light on what might be wrong ?
