Hello,

I have problems with H.264/AAC transport streams transcoded by FFmpeg. 
The playback isn't smoothly by RTSP server and VLC as client. Other TS 
files f.e. transcoded by VLC are OK, but I'd like to use ffmpeg 
directly. If I play TS file local or by HTTP apple streaming, then 
playback is fine. I uploaded an example TS:
https://rapidshare.com/files/1763103204/mp4.zip

FFmpeg is newest revision from GIT. I use following command for 
transcoding:
ffmpeg -i mp2.ts -y -re -isync -vcodec libx264 -r 25 -b 600k -vprofile 
baseline -preset fast -tune grain -level 1.2 -acodec libfaac -ab 64k 
-ac 2 -f mpegts mp4.ts

I hope you can help me. Thank you!

BR, Mike
