2.6.11beta problems

[pchristy]

I can't get the new beta to do anything useful, as it crashes on everything I've tried. My previous build (from git 29/11/2015) worked fine.

System: Slackware64-current.   gcc: 5.3.0

Example: Load any video (default 1920x1080 from my camera), try and transcode to H264 or H265  and/or resize to 720x576 using either swresize or OpenGL. As soon as I try and preview, avidemux closes instantly - sometimes leaving a crash file, sometimes not! Attempting to save the video without previewing produces exactly the same result - an instant crash.

Running avidemux from the command line to try and see what is going on produces the following:

(trimmed to what looks relevant!)

It may be that Slackware64-current is using some cutting edge software (gcc?) which the beta doesn't like? For another program I use regularly, I've had to pass "-std=gnu89" to the compiler, but that one actually fails to compile. Avidemux does compile, although I see lots of (non-fatal?) developer warnings going through.

Any ideas?

Cheers,

It seems to crash in the libVA hardware decoding
What video card are you using ? intel ?

[pchristy]

Hi Mean, thanks for the quick response!

Yes, its the Intel integrated graphics that comes with a Gigabyte Z97X-SLI motherboard:

Hope this helps!

Nearly all my work is with video, so I don't need the kind of 3D graphics acceleration required for games, and the Intel chipset is generally excellent for video work.

If you disable libVa for decoding, does it work fine ?
(BTW if you use libVa for decoding, you should use libVa for display also, it's much faster as there is no need to transfer data back and forth between CPU & GPU)

[pchristy]

Yes, disabling LIBVA decoding fixes it, although speed suffers. Using LIBVA for the display doesn't cause a crash, just decoding. When I re-enable hardware decoding, the crash window reports:

could you do a gdb backtrack with debug enabled so that i have where it crashes exactly ?
Thanks

[pchristy]

Yes, quite happy to do that, but how do I do it?

Cheers,

[mean]

If you used bootstrap, add --debug i.e. bash bootStrap.sh --debug --rpm

gdb avidemux3_qt[45]
r
wait for it to crash
bt

[pchristy]

Thanks! Currently rebuilding! I guessed I needed to rebuild with --debug, but wasn't sure what I needed thereafter! (This isn't something I do every day!)

Will report back soon.

Cheers,

[pchristy]

You're gonna love this! I rebuilt the package with the --debug option added to bootStrap.bash - and the program ran perfectly (thought gdb) without crashing!!!

Er, what do I do for an encore?

I'm going to rebuild it again, though the last build clearly showed "debug build" at all the status confirmations, but this time I'll completely remove the original package before installing the debug version. The last time I simply "upgraded" it.

Any other suggestions?

[mean]

Please redo the same with non debug build, to confirm the culprit is switching between debug & release

[pchristy]

OK, running the original build through gdb produced a crash:

Just to confirm, I've re-installed the debug version, and that is running perfectly!

I'm glad its you trying to fix this one and not me!!!   

[mean]

Could you try this
Edit avidemux_core/ADM_coreImage/src/ADM_imageUtils.cpp
and at line 908
replace
   #ifdef ADM_CPU_X86
by
   #if 0

Does it still crash and is the output correct ?

[mean]

Youll need to rebuild &install avidemux_core

[mean]

and what is the width of your video ?
