  • XMP PHP

    13 mai 2011, par

    Dixit Wikipedia, XMP signifie :
    Extensible Metadata Platform ou XMP est un format de métadonnées basé sur XML utilisé dans les applications PDF, de photographie et de graphisme. Il a été lancé par Adobe Systems en avril 2001 en étant intégré à la version 5.0 d’Adobe Acrobat.
    Étant basé sur XML, il gère un ensemble de tags dynamiques pour l’utilisation dans le cadre du Web sémantique.

  • ffmpeg : StreamNotFound error

    27 janvier 2017, par KMG

    I’m using Adobe Media server and push streams to this server using FMLE.

    My stream name : appvideo

    When I tried to pull the video from the server using ffmpeg/ffplay, I’m not getting "stream not found error". Whereas rtmpdump can stream the video.

    After I see the logs, all the ffmpeg request logs have a stream name with extension .flv like [appvideo.flv]. But rtmpdump not append this extension [ like appvideo].

    FFMpeg/ffplay log in Media server :

    play    stream  2017-01-27  02:26:17    GMT appvideo    10.11.12.202    32715   11  17  _defaultRoot_   _defaultVHost_  live    _definst_   0   404 183.82.250.50   rtmp    -   rtmp://10.11.12.202:443/live    rtmp://10.11.12.202:443/live    -   --  4702122229742256497 3135    3631    normal  appvideo    -   -   rtmp://10.11.12.202:443/live/appvideo.flv   rtmp://10.11.12.202:443/live/appvideo.flv   -   flv 0   0.000000    0   -   0   0   -   -   -   -   1   -   --  -   -   -   -   -   -   -1  -1.000000   -

    Not sure why request append .flv extension at last like this : rtmp ://10.11.12.202:443/live/appvideo.flv

  • ffmpeg version 2.6.8 : Stream specifier ':a' in filtergraph description matches no streams

    16 décembre 2020, par Ashitaka

    I am not getting why this isn't working.. I have tried to get the video streams with [0:v]/[0:1]/[0:v:0] & the audio streams with [0:a]/[0:0]/[0:0:0].
nothing worked.

    


    Explaining the inputs :

    


    1.1st input stream is a video that can be of varying resolution on which the filter adds a padding on to make it 600:480.

    


    2.2nd input is an overlay png which is already at 5:4 ratio.. just making it 600:480 before it gets overlaid in the filter.

    


    3.3rd & 4th ones are also videos which I don't care if they get stretched.. n they are getting stretched to 600:480.

    


    4.so finally there are 3 streams 1 overlaid video 2 stretched videos which needs to be concatenated.

    


    here's the command :

    


    ffmpeg 
-i '/home/vidinflux/public_html/assets/temp/2018020116464612/2018020116464612.mp4'

  • FFmpeg - feed raw frames via pipe - FFmpeg does not detect pipe closure

    8 septembre 2018, par Rumble

    Im trying to follow these examples from C++ in Windows. Phyton Example C# Example

    I have an application that produces raw frames that shall be encoded with FFmpeg.
    The raw frames are transfered via IPC pipe to FFmpegs STDIN. That is working as expected, FFmpeg even displays the number of frames currently available.

    The problem occours when we are done sending frames. When I close the write end of the pipe I would expect FFmpeg to detect that, finish up and output the video. But that does not happen. FFmpeg stays open and seems to wait for more data.

    I made a small test project in VisualStudio.

    #include "stdafx.h" 
    
//// stdafx.h 
    
//#include "targetver.h"
    
//#include

    As you can see in the last line of te FFmpeg output, the images got trough. 10 frames are available. But after closing the pipe, FFmpeg does not close, still expecting input.

    As the linked examples show, this should be a valid method.

    Trying for a week now...
