You are exactly right Lou, that were my assumptions.
Thank you very much for the help and the ready-to-use video filter!
Many thanks,

Hello all,
I am attempting to take an rtmp stream and push it out over multicast. It
appears like it is working on the server end and I can see the packets pushed
out; however the video does not play in any player. If I run wireshark on the
receiving machine I can see the rtp packets arriving

I think this is not the source of the problem: I saw the same bitrate in the
time of frame which I visually compared; s

Hello everyone,
and sorry if the title is convoluted, I couldn't find a better one. What
I'm trying to accomplish is simple, in practice: Assume I have three files:
- Left_Audio.mp3
- Right_Audio.mp3
- Video.mov
(Extensions are not important). What I would like to achieve is to come up
with a CLI

Do not use --disable-yasm unless you want a slow,
unsupported output. yasm is a small, selfcontained
binary, compile it yourself and put it somewhere in

1. Send an email to Microsoft.
2. Try -write_xing 0

Mainly because of network throughput. Mencoder can make it pretty well.

I tried to encode it without maxrate and t

Why do you want CBR? I don't think mencoder is giving you CBR.

P. S. Thanks for your very quick answer.

Hi all,
I used these commands to encode my videos:
for pass in 1 2; do
mencoder -oac mp3lame -lameopts cbr:br=128 -ovc x264 -x264encopts pass=$
pass:preset=veryslow:fast_pskip=0:tune=film:frameref=15:bitrate=1000 -o out.

Hi all,
I'm using ffmpeg to concatenate some mp3 audios.
There is no problem when playing the concatenated audio with VLC and WMP.
But if I inserted them into PPT files with Microsoft PowerPoint, the duration
displayed in powerpoint is smaller than actual duration. And the player stopped
