How to convert pcap to avi file with video and audio by gstreamer?
I need to read a pcap file and convert it into a avi file with audio and video by using gstreamer.
If i try the following command, it only works for generating a video file.
Video Only
gst-launch-0.10 -m -v filesrc location=h264Audio.pcap ! pcapparse src-port=44602 !"application/x-rtp, payload=96" ! rtph264depay ! "video/x-h264, width=352, height=288, framerate=(fraction)30/1" ! ffdec_h264 ! videorate ! ffmpegcolorspace ! avimux ! filesink location=testh264.avi
Audio Only
And if i use the following command, it only works for generating a audio file.
gst-launch-0.10 -m -v filesrc location=h264Audio.pcap ! pcapparse src-port=7892 ! "application/x-rtp, payload=8" ! rtppcmadepay ! alawdec ! audioconvert ! audioresample ! avimux ! filesink location=test1audio.avi
Video + Audio
When i combine two commands as follows, i encountered an error message -- ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc1: Internal data flow error.
gst-launch-0.10 -m -v filesrc location=h264Audio.pcap ! pcapparse src-port=44602 !"application/x-rtp, payload=96" ! rtph264depay ! "video/x-h264, width=352, height=288, framerate=(fraction)30/1" ! ffdec_h264 ! videorate ! ffmpegcolorspace ! queue ! mux. filesrc location=h264Audio.pcap pcapparse src-port=7892 ! "application/x-rtp, payload=8" ! rtppcmadepay ! alawdec ! audioconvert ! audioresample ! queue ! avimux name=mux ! filesink location=testVideoAudio.avi
Please kindly give me some solutions or suggestions with regard to this issue. Thank you in advance. Eric
而不是第二个“filesrc！pcapparse”为第一个pcapparse指定一个名称= demux，删除src-port arg并从demux启动第二个分支。
