[FFmpeg-user] Trouble with encodnig UDP->RTMP

Mon Nov 16 18:11:41 CET 2015

Hello,everybody.

I have some problems with my UDP-> RTMP stream.

To start with I do it by this script:

#!/bin/sh
exec 2>&1

in="udp://127.0.0.1:10078?reuse=1"
out1="rtmp://127.0.0.1:1935/appname/test.sdp"

exec /usr/bin/ffmpeg -re -i $in -maxrate 3000k -bufsize 256000 -vcodec libx264 -s 1024x576 -x264opts keyint=50 -keyint_min 25 -acodec libmp3lame -ar 44100 -deinterlace -f flv $out1

That`s what I tryed to change but there was no result:
#exec /usr/bin/ffmpeg -re -i $in -bufsize 256000 -vcodec copy -acodec libmp3lame -ar 44100 -deinterlace -f flv $out1
#exec /usr/bin/ffmpeg -re -i $in -vcodec libx264 -s 1024x576 -x264opts keyint=50 -keyint_min 25 -acodec libfaac -deinterlace -f flv $out1
#exec /usr/bin/ffmpeg -re -i $in -vcodec libx264 -acodec libfaac -deinterlace -f flv $out1

When I start streaming,ffmpeg log:

When ffmpeg write "Error while decoding stream #0:1: Invalid data found when processing input" sound stops for a second and there is no problems with stream for about an hour,after that video  or audio disappears and there are a lot of artefacts.
Ffrobe of stream at this moment isn`t differ with ffprobe at the beginning.

I made the tcpdump of UDP stream and collect it into the stream(Follow the udp stream by Wireshark)when problem appears,and there is no problems with it.

ffrobe of UDP:

ffprobe udp://127.0.0.1:10078?reuse=1

Maybe problem connects with encoding (mp2 (native) -> aac (libfaac))
? Can anybody help?
