Hi, I'm having troubles using redbutton. I live in London and I get dvb-t fron uk-CrystalPalace. I'm using a Haupauge WinTV NOVA T USB2 kernel 2.6.18 , v4l-dvb latest from mercurial. redbutton latest svn Then in one window I do tzap "BBC ONE" elsewhere rb-download -v -l 4164 and in one other window (from the same directory) rb-browser -vv services/4164 > log.txt the rb-browser prints the following error message [mp3 @ 0xb7e63e44]incorrect frame size [mp3 @ 0xb7e63e44]incorrect frame size Segmentation fault and log.txt is the file attached. rb-download keeps running troughout the test. rb-browser shortly shows the black window with "LOADING" on the top right and the crashes. Same thing fro ITV1. I'm not too good with gdb, but this is the stack at the moment of the crash: one of the threads #0 0xb7f57410 in ?? () #1 0xbffd27e8 in ?? () #2 0x0000127c in ??

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, it looks like a bug in libavcodec which is part of the ffmpeg package - though I don't know why we would be using mpeg1_encode_picture_header() - what version of ffmpeg are you using? and does the crash happen at the same point everytime?

The bug is showing most of the times but not always and always at the same place. I've recompiled ffmpeg with --enable-pthread and it has not occurred any more. Could it be the reason?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, not having pthread support compiled in would probably cause ffmpeg to crash if two threads tried to use it at the same time sounds like you've fixed the problem, but let me know if it starts happening again...

I've managed to install the font, thank you. I've tried to run rb-download without -l and I get a better behaviour of rb-browser, even though sometimes it hangs with "please wait..." and never comes back (but it is non reproductibile, and in different places). I'll try to give you some exact exalmple of the behaviour. When running with "-l", contrary to what I said in a previous mail, I still experience situations (most of the times) where I cannot close the application with the top right button. I've got a Intel Centrino (1.5 GHz), both application on the same PC.
