  • Scrape mp4 file from a URL ? [on hold]

    22 juillet 2013, par TJE

    I am running ffmpeg on my server and am using it with PHP. I was wondering if it was possible to enter a URL of a web page and have it search the source code for a .mp4 file. Then use that as the uploaded file in the HTML form and process it with PHP. I would also like to be able to scrape other data found on the page.

    Can someone recommend a good tutorial or lesson for scraping data by just entering a URL in an HTML form ? Or just answer my question if it's simple. I am a bit of a noob at this.

  • Playing and recording a live stream from another computer webcam using VLC/FFmpeg [closed]

    22 octobre 2012, par user573014

    I was trying lately to set a video server on one machine and play it in a differen machine, it works with me.. but the problem is that it always stuck and become jammed in the middle .. and it is very slow comparing to the original stream.. something like 5 seconds delay which is not acceptable at all !
    The warning messages I get usually includes something like that :
    in the client side, which is the one which is jammed

    [0x24d1ab0] ts demux warning: discontinuity received 0x5 instead of 0xe (pid=68)
    
[0x7f4340015e50] rtp demux warning: 2 packet(s) lost
    
reference picture missing during reorder
    
Missing reference picture
    
mmco: unref short failure
    
Reference 4 >= 4 (H264 - MPEG-4 AVC (part 10)) stopped
    
error while decoding MB 34 14, bytestream (575)

    and that is the picture of the streaming when it is jammed

    jammed stream

    and that is what it looks like when it is running smoothly

    smooth stream

    This is the error message I got on the server

    [0x2513820] main generic debug: auto hidding mouse
    
[0x2296230] main mux warning: late buffer for mux input (1840085)

    and Finally here is my command line that I am using >
    on the server :

    vlc -vvv v4l2:///dev/video1:v4l2-width=640:v4l2-height=480 --sout 
    
'#duplicate{dst=display,dst="transcode{vcodec=h264,vb=800,ab=128}
    
:duplicate{dst=rtp{mux=ts,dst=172.22.2.87,port=50004}'

    on the client :

    vlc -vvv rtp://@:50004

    I thought that it might be from VLC or from my command .. I tried different protocol for transmission, with no luck I also tried FFmpeg and I got similar results + warning messages .. I thought then that both of them are using the same libraries in Linux

    here is the command using FFMpeg :

    ffmpeg -f video4linux2 -i /dev/video1 -vcodec libx264 -s 320x240 -pix_fmt 
    
yuv420p -vb 200000 -minrate 200000 -maxrate 200000 -bufsize 2000000 -acodec 
    
libmp3lame -ab 128k -ar 44100 -ac 2 -f mpegts udp://172.22.2.87:5544

    In conclusion, I would like to find a solution for the latency of the streaming (which is very high) and the jamming problem
    I appreciate anyone's input, thank you
