You will need to send me the sample (preferably a small part of it as long as it
causes the crash) so I can try to reproduce it.

Hi,

Thanks for the quick response.  I just tried it on the mp4 file attached to 
Issue-9
and it faults using that.

I should have probably said in my report that this is running on a ppc 
processor.
(1st gen mac mini)

Also, If I tried the first command and received a "Could not open input file" 
error,
then once I renamed it to n.mp4 it read the file but then crashed on execution.

The session is shown below:

root@server:~# /usr/local/bin/ffmpegthumbnailer  -i Jim\ Flying\ Alarm\ 
Clock.avi -o
pic.png
Error: Could not open input file: Jim Flying Alarm Clock.avi
root@server:~# cp Jim\ Flying\ Alarm\ Clock.mp4 n.mp4
root@server:~# /usr/local/bin/ffmpegthumbnailer  -i n.mp4 -o pic.png

In that case can you try the code in subversion. There has been a fix this week 
which
should fix segmentation faults when using ffmpeg with altivec (memory alignment
thing). Since you have a powerpc you are probably using altivec.

Are you sure your ffmpeg installation is still ok? Try building from scratch 
with
version 1.5.3 which was released today.

I'll remove and rebuild ffmepg and then ffmpegthumbnailer, hopefully tomorrow
evening.  I'll post back when I've done that.

Ok - I've done that now and it is working in some cases.  It looks like 
something was
wrong with my ffmpeg build.

I'm using it in mediatomb to display movie thumbnails in the 0.12 svn code 
(r2019)
and it still causes crashes with some of my media.  I'll try and find a 
selection of
the offending files and upload some samples.

Once I find problem files what is the best way to isolate a small part of them 
for
upload here?

Apologies for the lack of information about what file types are problematical 
etc - I
need to sleep before work tomorrow, but will look into it more when I get a 
chance
this week.

Thanks for your efforts so far :)

you can use ffmpeg to take only a small part of the file
ffmpeg -i in.avi -t 1 out.avi

This will create a video containing the first second of in.avi

This appears to be fixed now in the standalone case.

I wrote a shell script to create thumbnails for all my videos and it succeeded 
on all
of them.

It crashed when using mediatombs built in thumbnail generation with the above 
stack
trace, however if I use the previous transcoding method of generating 
thumbnails then
they work just fine. (and I can also implement my own cache to speed things up 
this
way too)

I'll raise this crash with the mediatomb developers directly.

Thanks for your help.

If mediatomb is statically linked against ffmpegthumbnailer then it will keep
crashing. Have you tried rebuilding mediatomb?

Original comment by dirk.vdb on 9 Jun 2009 at 3:04

GoogleCodeExporter commented 9 years ago 
Yes I rebuild that.  

I did a "make uninstall && make clean" for mediatomb, ffmpegthumbnailer & 
ffmpeg.

I've not looked at how mediatomb links to the lib - I'll rebuild it again just 
to be
certain.

Before filing a bug report at mediatomb, can you verify the following:

(run these three commands)
wget http://ffmpegthumbnailer.googlecode.com/svn/trunk/main.c
gcc `pkg-config --libs --cflags libffmpegthumbnailer` main.c -o test
./test amovie.avi

This should generate a file output.jpg conatining a thumbnail

This is to test if the flat c api is working correctly. Mediatomb uses the c api
ffmpegthumbnailer uses the c++ api

Regards,
Dirk

I've run the above and they complete fine.

I also rebuilt mediatomb and it does indeed still crash with the previous stack 
trace.

Thanks for the help with this,  I'll file a bug with mediatomb now I guess.

Original comment by kris.koleman on 10 Jun 2009 at 6:10

GoogleCodeExporter commented 9 years ago 
One last check could be to compare the output of

ldd /usr/bin/ffmpegthumbnailer | grep thumbnailer
ldd /usr/bin/mediatomb | grep thumbnailer

they should be the same.

I looked at how mediatomb uses the ffmpegthumbnailer library, it;s exactly the 
same
as the main.c file. I doubt the problem is in mediatomb.

Original comment by dirk.vdb on 10 Jun 2009 at 6:25

GoogleCodeExporter commented 9 years ago 
mediatomb was linking against a different version of the lib in /usr/lib not
/usr/local/lib 

I guess these were left over from a previous install from apt that didn't get 
removed
since everything I've built I've installed to /usr/local/.

Thanks again,
