problem getting audio from mpeg stream

hi I have mpeg stream (dvb-t) which stop afer 143 seconds , whether
using lame, ogg, mp2 or even dvd

the error is Invalid timestamps stream=0, pts=3569850528,
dts=8276486691, size=158 (or some variation)

is there any way to force ffmpeg to continue (there is audio after
this point - and only audio mp2/3 not able to determine which -
probably mp2)

version is SVN-r16447 (fairy old I know)

ffmpeg 0.5 doesn't produce playable files

I have recently tried out ffmpeg 0.5. I was able to make it compile, 
but the files it produces don't play on Quicktime. When I tried 
converting an flv file into a mp4, ffmpeg displayed this error 
repeatedly:

Error while decoding stream #0.0
[flv @ 0x1804200]Bad picture start code
[flv @ 0x1804200]header damaged

I know it is not the file's fault because older versions of ffmpeg can 
convert the file just fine. I did try other files and received error 
messages like the one above. I compiled ffmpeg 0.5 using gcc 3.3 on Mac 
OS 10.3.9.

Here is some more information about this version:

FFmpeg version 0.5, Copyright (c) 2000-2009 Fabrice Bellard, et al.
   configuration: --disable-altivec
   libavutil     49.15. 0 / 49.15. 0
   libavcodec    52.20. 0 / 52.20. 0
   libavformat   52.31. 0 / 52.31. 0
   libavdevice   52. 1. 0 / 52. 1. 0
   built on Mar 31 2009 14:55:50, gcc: 3.3 20030304 (Apple Computer, 
Inc. build 1666)

Anyone have a solution to this problem?

making a 3600x3600 mpeg2 fails

Hi list,

It is not conforming the mpeg2 specifications but I need to generate  
3600x3600 from a bunch of jpegs.
All seems to go well but the end result is rather strange..

What I do is :

ffmpeg -i d_%05d.jpg -s 3600x3600 -t 30 -r 5000k -f mpeg2video d.m2v

make clean

make

Cheers, I thought "make clean" was the way to remove out of date stuff!
Just for clarity what is the difference between "distclean" and "clean"?

Video playback half the speed with encoding AVCHD files

Hello there,

Every time I try to convert my AVCHD files, my video playback is half
the speed the audio is playing.  What is the proper command I should be
using in FFMpeg to convert AVCHD files?

Thanks
