How to save and play RTP streams having payload DVI4 8K? Is there any free software which decodes this payload like G729 decoder which decodes G729 payload successfully.....?? If anybody has the software please send me the link here so that I could download and install that software.
Regards....
Wireshark has been able to handle dissection of DVI4 8K for a long time. One of the RTP captures on the Sample Captures wiki page contains DVI4 8K data, it's conveniently named sip-rtp-dvi4.pcap.
Playing the audio stream may be more difficult, on my machine (Windows 10, Wireshark dev build 3.3.0-rc) I don't hear any audio from the stream.
But I'm not able to decode DVI4 8K payload. As I've saved the RTP streams in .raw format and tried to play by audacity using 32kb ADPCM and clock rate 8000, 16000 Hz, but what I get in result is just noise only. So plz let me know is there any software or setting in wireshark to save and listen this PT DVI4 8K. Anybody having any idea please share.
Anybody who could tell step by step procedure to decode or analyse Payload Type DVI4 8K, 16K...???? Also I've tried the sample capture given above in the comment section, but that was not the exact one that is it's not DVI4, It's different payload type....So again not abled to solve my problem.....????
