  • Gstreamer errors when streaming on windows

    19 juillet 2014, par user2656632

    I tried to streaming video by gstreamer using this :

    Sender :

    gst-launch ksvideosrc ! ffmpegcolorspace ! ffenc_mpeg2video gop-size=1 ! mpegtsmux ! rtpmp2tpay ! udpsink host=127.0.0.1 port=5000

    Receiver :

    gst-launch udpsrc port=5000 caps="application/x-rtp, media=video, clockrate=90000, encoding-name=MP2TS" ! rtpmp2tdepay ! ffdemux_mpegts ! ffdec_mpeg2video ! ffmpegcolorspace ! directdrawsink

    It works, but wrong. I got very low fps and I got this output :

    How I can fix these issues ?

  • Can't write out flv file in openCV in Windows

    7 août 2015, par dev_nut

    I’m trying to write out a flv file in openCV 2.4.9 in Windows 8.1 and it seems this gives an error.

        [flv @ 05821a00] Tag FLV1/0x31564c46 incompatible with output codec id '22' ([2]
    
[0][0][0])

    After googling around, I noticed that I may have to recompile with ffmpeg support. I set up cmake (I’m a cmake noob) and did that. But, I didn’t change anything with regard to ffmpeg (like point to new libraries). I can’t seem to find a guide that would help me here.Is this the right way to go ? Would recompiling in this case, actually help at all ?

  • WebRTC Experiment : Chrome windows audio not sync

    10 juillet 2014, par putoshop

    I tried to make the audio work for Chrome using this Git Repo, but I’m having a sync problem with video and audio. The audio finished playing earlier. The video seems to be correct. I noticed that when I play the blob, the audio is playing fast.

    I was able to make the audio work by commenting the line the throws error in the condition that check if sampleRate is less than 22050 or greater than 96000 in RecordRTC.js.

    I tried to adjust the sampleRate other values and noticed that If the sampleRate is low, the audio plays slow and if the sampleRate is high, the audio plays fast. I was able to make the audio and video somewhat sync but it seems the pitch of the audio becomes noticeable lower than the expected pitch.

    I’ve also tried FFMPEG to adjust the length of the audio to match the video length, but didn’t been able to make it work.

    the extensions of the files that are uploaded to the server for Chrome are .webm(video) and .wav(audio).
