RTP packets detected as UDP
28 février 2017, par user3172852Here is what I am trying to do :
WebRTC endpoint > RTP Endpoint > ffmpeg > RTMP server.This is what my SDP file looks like.
var cm_offer = "v=0\n" +
"o=- 3641290734 3641290734 IN IP4 127.0.0.1\n" +
"s=nginx\n" +
"c=IN IP4 127.0.0.1\n" +
"t=0 0\n" +
"m=audio 60820 RTP/AVP 0\n" +
"a=rtpmap:0 PCMU/8000\n" +
"a=recvonly\n" +
"m=video 59618 RTP/AVP 101\n" +
"a=rtpmap:101 H264/90000\n" +
"a=recvonly\n";What’s happening is that wireshark can detect the incoming packets at port 59618, but not as RTP packets but UDP packets. I am trying to capture the packets using ffmpeg with the following command :
ubuntu@ip-132-31-40-100:~$ ffmpeg -i udp://127.0.0.1:59618 -vcodec copy stream.mp4

So can you help me figure out :
- why wireshark cannot detect the packets as RTP (I suspect it has something to do with SDP)
- How to handle SDP answer when the RTP endpoint is pushing to ffmpeg which doesn’t send an answer back.
Here is the entire code (hello world tutorial modified)

bash script to install / update ffmpeg static builds
1er mars 2017, par JoakimHi I’m trying to make my first "real" bash script to do some real work than can be executed both manually and through cron jobs.
The script should download and install the ffmpeg-static-build from https://johnvansickle.com/ffmpeg
Here is what I’ve got so far :
#!/bin/bash
# Still to come, see if the script runs with root privileges else exit
#Download FFMPEG static daily build and it's md5
cd ~
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | tar -xf
#wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5
curl -L https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5 | tar -xf | tee -a https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | cut -d\ -f1 | md5sum > md5sum.txt
#Chech the md5 is currect
#md5sum -c MD5SUMS
file1="md5sum.txt"
file2="ffmpeg-git-64bit-static.tar.xz.md5"
if ! cmp --silent "$file1" "$file2"; then
echo "md5sum doesn't match...\n exit" >&2
exit 1
fi
#tar -xf ffmpeg-*.tar.xz
cp ffmpeg-*-static/ff* /usr/bin/
cp ffmpeg-*-static/ff* /usr/local/bin/
cp ffmpeg-*-static/qt-faststart /usr/bin/
cp ffmpeg-*-static/qt-faststart /usr/local/bin/
# Consider change second location to use ln -s
# Remove downloads and do some clean up
rm -fr ffmpeg-*
#EOFAs you can see in the script i would like to add the md5sum check but it fails (got the md5sum check part from Compare md5 sums in bash script)
If i remove the md5sum part the script is working, but right now the script fails at the | tar -xf | part with this code

update
Have made some changes to the script based on the suggestions in this thread, but my problem is I have no output what so ever at this state :( So I think it’s time to ask for the next clue
#!/bin/bash
# version 0.3z
## Download FFMPEG static daily build and it's md5
##
## To make this script working you might need to change the below values
## based on whether you are using a 32bit or 64 bit OS

## and then change those below
##
## If you are running on a shared server or dowsn't have root priviliges you might need to uncomment
## point 5.
# a "~" means running users home folder :) and should be different from destination dir
download_dir=~
# as this can change if the ffmpeg is to be stored on ex. shared server
dest_dir=/usr/bin/

# 2. Check the md5 is correct or have changed from last check
## instead of downloading ffmpeg-git-64bit-static.tar.xz every time,
## regardless if it is new or not, I recommend only downloading it
## if the md5 does not match. Would save John some bandwidth at least
## thx for the idea to @LordNeckbeard
## So somehow i'll guess some sed or grep only first part is nessesary :(
## This is getting more advance than expected for a first time script :/

running the very same "if" part typed directly into the shell/terminal itself it’s all happy !!
