  • How would I use ffmpeg to download this stream ?

    2 novembre 2015, par amos

    I want to download this http://webcast.mit.edu/spr2014/csail/12apr14/ video

    I’ve downloaded the smil file, installed ffmpeg, however I don’t know which url to use. Moreover, it may need flash authentication which I don’t know how to do either.

    smil :

    <smil>
    
  
    
    
    
  
    
  
    
    <switch>
    
      <video></video>
    
      <video></video>
    
     </switch>
    
  
    
</smil>

    Please help me with the exact command I could use.

  • FFmpeg error message when processing

    19 avril 2013, par FlyingCat

    Hi I am using FFmpeg to get the image from several video files.

    I got my ffmpeg codes ready but I got the following error when I exec my codes.

               $image_source_path = &#39;/test/project/test.mp4&#39;;
    
               $ALL_PLACE_WIDTH = 300;

               $image_cmd = " -r 1 -ss 00:00:10 -t 00:00:01 -s ".$ALL_PLACE_WIDTH."x".$ALL_PLACE_HEIGHT."   -f image2 " ;
    

    
               $dest_image_path = &#39;/test/project&#39;;
    

    
               $str_command= $ffmpeg  ." -i " . $image_source_path . $image_cmd .$dest_image_path;
    
               shell_exec($str_command);

    It seems my linux want to me switch avconv. I am not sure how to fix these errors. Can someone give me a hint about it ? Thanks so much !

  • Desktop streaming to Wowza server using ffmpeg

    24 avril 2013, par Gergely Lukacsy

    Recently, I'm trying to utilize ffmpeg for streaming live desktop screen to a Wowza media server.

    I have partial success on the subject so far :

    I've managed to record desktop screen using the UScreenCapture directx dshow filter, and I'm also able to send this record to the server.
    However, when I'm trying to send the screen directly to the server, it fails every time. The player is buffering pretty slowly, and shows a blank screen when it's done (the counter keeps counting).

    So, here are the working methods

    for recording screen :

    ffmpeg -f dshow -i video="UScreenCapture" -r 25 -vcodec libx264 output.flv

    and for streaming video :

    ffmpeg -re -i  -map 0 -c copy -vbsf h264_mp4toannexb -f mpegts udp://stream.server.xyz:52000?pkt_size=1024

    And this is the code I'm using :

    ffmpeg -f dshow -i video="UScreenCapture" -s width x height -r framerate -vcodec libx264 -pix_fmt yuv420p -b:v bitrate -an -vbsf h264_mp4toannexb -f mpegts udp ://your.destination.url:PORTNUMBER ?pkt_size=some_bytes

    As far as I can remember, it worked well before I upgraded wowza.

    Some additional info :

    • OS : win7 sp1 64bit
    • ffmpeg N-49610-gc2dd5a1 (Zeranoe FFmpeg build 2013 Feb 5)
    • UScreenCapture : x64 Edition Version 2.0.14
    • Wowza 3.5.2 running on a Debian linux 2.6.32-5-amd64
    • Flowplayer : 3.2.15

    Looking trough the Wowza log files, something caught my attention. It seems when I'm streaming desktop screen, the server somhow gets uncomplete packets, but when I'm streaming a video file, the error doesn't occurs.

    What causes this error ? Any ideas ?

    Thanks in advance !
