回复： How to convert to PCAP to webm video?

[birdhur]

Thanks for your response, thanks so much! 
  
  
 I used the following command:
            gst-launch-0.10 webmmux name=mux ! filesrc location=oldfile.ext ! filesink location=newfile.webm ! name=demux ! demux. ! ffmpegcolorspace ! vp8enc ! queue ! mux.video_0 ! demux. ! progressreport ! audioconvert ! audiorate ! vorbisenc ! queue ! mux.audio_0
  
   And it say " No such element or plugin ffmpegcolorspace'
  
  BTW, I used the version gstreamer-1.0-x86-1.2.3.msi
  
   :) 
       I am a Java engineer, and have knoledge of c and c++.  If can you do me a favor and help me convert one pcap to webm file?  I just want to compare the webm file and the pcap file,  and see the mapping between pcap payload and the webm content?  Sorry for bother you !

  Where does it fail? After getting the H264 frames you should be able to generate any format. Here is my pipeline that displays from a PCAP file.

gst-launch filesrc location=$1 ! 'raw/x-pcap' ! queue ! pcapparse src-ip=$2 src-port=$3 dst-ip=$4 dst-port=$5 ! \
    'application/x-rtp,media=video,payload=104,clock-rate=90000,encoding-name=H264' ! \
    rtph264depay byte-stream=true ! video/x-h264 ! ffdec_h264 ! xvimagesink


I would think that you could simply replace the h264 decode and display with code to generate the webm format, then write to file.

I have tried many times, but didn't successfully.  Could some guys do me a

   I used the tool of gstreamer-1.0-x86-1.2.3.

   Thanks in advance!
