Segmentation Fault

Hi there,

I'm experiencing problems trying to get ffmpeg/ffserver to work.

This is what I try to do:

- get a feed from a Linksys WVC54G webcam;
- stream that into ffserver (using ffmpeg);
- have ffserver restream the output;
- read the output stream (using e.g. ffplay or WMP).

I am using the latest SVN stuff and latest GCC, on top of a SuSE 8.1
system, uname -a says:

Linux angeldust 2.4.33.3 #1 SMP Fri Oct 27 19:42:41 CEST 2006 i686 unknown

Compiling the source is no problem at all, nor is installing it.
FFplay works fine too, but I can't get the server to stream properly
and after a while it produces a Segmentation fault:

Ping in the original thread. Or post the complete info again. Why force
people to dig in old messages? And which one are they supposed to reply
to, the old thread or this one?

This *is* the original thread (original and previously only message
posted on the 6th); he just didn't quote anything, so only people who
happen to have kept the old message and threaded the new one correctly
will see the fact.

Sorry. When Henk's 2nd message arrived, I could swear that Thunderbird
did not show any hint of threading, esp. no "Re:". At that point his 2nd
message was in my IN box but the 1st had already been filed in my ffmpeg
archive folder. But if I look at the full headers now, the 2nd message
has both "References" and "Re:".

Maybe I am like Terminator2: "I need a vacation" :-)

I shall repost, see below.

I feel a bit awkward about it, though, as I feel that reposting
is offensive en impolite: why fill up everybody's mailbox with the
same stuff over and over again? Anyway, as you requested it, here
we go!

Any help you (or anybody else, for that matter) can give would be greatly
appreciated: I planned to use ffserver/ffmpeg to live-stream some event
and find myself rather stuck..

BTW: I currently use a more recent build of ffplay, but to no avail.

I have read a number of postings that suggest that the nighly
builds are not stable. Now, I have downloaded a fair number
of them, they all compile, ffmpeg seems to work fine, as does
ffplay, but ffserver keeps on SIGSEGV-ing. Is there someone here
who has a working stable ffserver up and running, if so, what
configuration, with which build/release?

I'd like to know, as I intend to download and compile such a
version myself - if that also SIGSEGV's, it _must_ be something
weird on my old SuSE box, I assume.

Help, anybody?

Not much response yet, I see. Anyway, I decided to do some
debugging myself. When the server crashes, this is what seems
to cause it:

--
Invalid read of size 4
at 0x806D4B5: av_read_frame_internal (utils.c:504)
by 0x7FFFFFFF: ???
Address 0x8 is not stack'd, malloc'd or (recently) free'd

Process terminating with default action of signal 11 (SIGSEGV)
Access not within mapped region at address 0x8
at 0x806D4B5: av_read_frame_internal (utils.c:504)
by 0x7FFFFFFF: ???
--

Any clues, anybody?

Please provide more context, most people don't store old mails in
their inbox, so you need to feed them with the complete command which
crashed ffmpeg/ffserver.

Regards.

One minute of pure noise with ffmpeg:
ffmpeg -ar 48000 -t 60 -f s16le -acodec pcm_s16le -i /dev/urandom \

I am an old school Internet user, who dislikes trashing other people's
mailboxes with the same stuff over and over again. However, I can see
your point, so, here it is again, and humble apologies for it:

Hi there,

I'm experiencing problems trying to get ffmpeg/ffserver to work.

This is what I try to do:

- get a feed from a Linksys WVC54G webcam;
- stream that into ffserver (using ffmpeg);
- have ffserver restream the output;
- read the output stream (using e.g. ffplay or WMP).

I am using the latest SVN stuff and latest GCC, on top of a SuSE 8.1
system, uname -a says:

Linux angeldust 2.4.33.3 #1 SMP Fri Oct 27 19:42:41 CEST 2006 i686 unknown

Compiling the source is no problem at all, nor is installing it.
FFplay works fine too, but I can't get the server to stream properly
and after a while it produces a Segmentation fault:

$ ffserver

This is the command I use to fire up the stream from the camera:
