2.6.11beta problems

[pchristy]

Will do. Might take a little longer this time......

Video is 1920x1080.

BTW, the debug version also works fine when NOT running through gdb.

[pchristy]

YES! That worked perfectly. I also tried re-sizing, and all the combinations that caused problems initially, and its all good.

I've renamed my local version as beta2, so that I could keep the different builds available, FYI.

I also built beta1 on my small and rather under-powered laptop. That uses ati chips throughout, but uses the open source drivers, and therefore vdpau rather than libva. That also worked perfectly, so it was clearly something Intel / libva related that was causing the problem.

Many thanks for a quick fix!

Cheers,

It's not  a fix
Just confirming that gcc is optimizing too much the code
Temptative fix in 5 mn

[mean]

Tempative fix commited
Should work, but not 100% sure

[pchristy]

No, that doesn't work! If you just do a simple transcode, it freezes. If you try a re-size, it crashes and vanishes as soon as you try a preview.

So its crashing slightly differently (the original didn't freeze), but it still doesn't work.

I'm going to have to leave it for today, now. Hopefully I'll get chance for another look tomorrow.

Cheers,

[pchristy]

Just tried running that last build through gdb, and again, it works perfectly - no crashes or freezes regardless of transcode or resize. It only mis-behaves if I run it directly!

Ignore that last post! I was having a brain-fade (it happens at my age!    ). I must have re-installed beta2 before I went to bed last night! I've just reinstalled the git build from last night and it crashes through gdb. This is the (release version) backtrace resulting from a transcode to x265 with a resize from 1920x1080 to 720x576. This happened as soon as I tried to preview the filter:

I think i've found the problem, even if i can't reproduce it
I'll commit the fix later today

Jan: Its not exclusive to x265 - it happens whatever I'm trying to do. I think Mean is right, its something to do with libva and hardware decoding. If I disable libva for decoding, it all works.

Mean: Thanks for your efforts!

I think that the last commit should prevent gcc from optimizing too much

[pchristy]

No, still not there.

Input 1920x1080 mp4 file, transcode to x265 and resize to 720x576. Preview in the filter window, and CRASH.

That's from the crash window. Do you want me to run it through gdb, or is that enough?

Do you know what gcc/g++ you are using ?
The changes i have made should be more than enough

[mean]

ok, i was distracted when doing the change
Now it should work (tm)

[pchristy]

Happy New Year, Mean! I hope you got out and celebrated a bit last night! I would feel very guilty if I thought you spent New Year's Eve slaving over a hot computer!

Sorry, though - its still crashing! Running it from a terminal window to try and get a trace produces this when I try and save the video:

That was the result from simply trying to save a transcoded and re-sized video, without previewing it. There was no crash window - it just freezes. If I try and preview it from the filter window, I do get a crash window:

I'm using gcc-5.3.0. I do have one other program - a very old one - that refuses to compile at all under 5.3 unless I pass it the "-std=gnu89". I do this like so:

Code Select Expand

CC="gcc -std=gnu89 -O2 -fPIC" ./configure
where "-O2 -fPIC" are the standard flags for an x86_64 build. But that is for a standard "configure / make / make-install"  build. I can't see anywhere in your bootStrap.bash script where similar parameters are set, or I would try it with gcc "throttled back", as with that other program. (Its a 2.4 GHz spectrum analyzer, by the way, nothing to do with video, and it won't compile at all without that parameter.)

Hope this helps!

BTW, one other bug I've stumbled across is that when I try and resize the video to 720x576, every time I try and enter the 576 it auto-corrects to 566! I cannot change the middle 6 back to 7 until I have entered all three digits! This is in the software resize window. 

Cheers,
