I am not sure how to attach the error pcap file here. So I am specifying the error packets as .csv format right here. ---------------------------- ERR...
Hello All, I am working with gstreamer, mainly playing around with music playback features. I am currently trying to use RTP to send mp3 streams over our LAN, but unsuccessfully until now. On sender side I use the following pipeline: gst-launch -v filesrc location=./my_music_file.mp3 ! ffdemux_mp3 ! rtpmpapay ! udpsink port=6969 host...
Hi, I captured a tcpdump of a SIP call to debug DTMF problem (repeated digits), but I have some problem interpreting it. From what I understand, when I parse the captured traffic through wireshark's "VOIP CALL", I should see something like this (for digits 123) : CAPTURE 1 RTP telephone event DTMF One 1 (end of event) RTP telephone eve...

I have the following code to send as audio RTP packet some DTMF digits: int count=0 for(int j = 0; j < samples; j++) { waves = 0; // dtmf tone 1 waves += sin( ((PI * 2.0f / 8000) * 697.0f) * count ); waves += sin( ((PI * 2.0f / 8000) * 1209.0f) * count); waves *= 8191.0f; //amplitude ++coun...
My C++ application receives a H.264 RTP video stream. Right now it decodes the stream, saves it into a YUV file and later I use ffmpeg to re-ecode the file into something suitable to watch on a Windows PC (eg. Mpeg4 AVI). Shouldn't it be possible to save the H.264 stream into a AVI (or similar) container without having to decode and re...
I am looking for an RTP lirbary for Android. So far I could not find any. Is there any such library? Alternatively, I think I can use any RTP library for JSE for which I can get the source code. I can compile the code in Android. I will be writing a proprietary application so the license has to permit that. Can anyone suggest a library ...
