Combination of transpose, scale, pad filters results in segfault

[Ignat]

Hi,

when I am trying to execute following transcode I receive segmentation fault.

( I am trying to rotate initial video and then scale it down, adding two equal vertical black stripes on the left and right).

What is most peculiar is that if I change pad to pad=152,270,0,0 this segfault does not happen.

Please find ffmpeg output below:

Is an external library (libx264) necessary to reproduce the crash?
Does the crash also happen with current git master?

Please provide backtrace etc. as explained on ​http://ffmpeg.org/bugreports.html

[Ignat]

Hi,
Thanks for the quick response.
I was able to get the crash with latest versions (of x264 and ffmpeg) with following results (below).
I will try to reduce command line to see if removing codec changes things.
(And since it is my local box now I will provide debug info for latest version, in some time)

[Carl Eugen Hoyos]

Is an external library (libx264) required to reproduce the problem?

Please recompile without --enable-shared, this will make the backtrace more useful.

[Ignat]

Please find gdb output for statically linked ffmpeg below.
Crash below was reproduced without transpose=3 filter.

I will investigate if using external library (x264) is required to reproduce crash tomorrow.

For some reason I still can reproduce the issue with latest (ffmpeg version N-34062-g4416931) ffmpeg and I can't find any resent pushes to git that would mention this ticket :(

Sorry for being insistent :(

This is the version you originally used when reporting the problem (and the version I used to reproduce it). Please update to current git head and test again.

[Ignat]

Thanks, turned out that I don't have understanding in teh ways of git. Got changes - will verify.

[Ignat]

Yes, I can confirm that it works. Have to run more thorough tests though.

Thank you!
