x265 crashes for no apparent reason

Post by Lazyncoder »

Hi,

I don't know if this is a x265 bug or it's HB's. So let's find out...
I use two command to increase x265 performance. pmode and pme.
about 80% of times, everything goes fine. but the other 20%, it crashes at a random point of the encoding. once at 15% and once on 95%.

when it crashes, HB doesn't know a thing. it still thinks the encoding is going on. logs don't show anything suspicious. "Time Remaining" freezes on whatever it is but "time elapsed" is still counting. CPU using for HandBrakeCLI.exe is absolute zero. it just stops encoding. no error or anything appears on the screen.

of course, when I don't use the commands mentioned above, everything goes fine.

is there any other info needed?

this is the encoding log but I don't think any useful info is there:

x265 is still experimental and in rapid development. A debugger (gdb) backtrace might be useful. But at the rate x265 is changing, any problems found in our build of it could easily be fixed in the master repo already.

Additionally, you are specifying the options incorrectly. No "--". Correct syntax would be "pmode=1:pme=1". I'm surprised it doesn't barf immediately and just give up.

OK, I did some tests with correct command line, yet the crashing still occurs. the situation is worse now with LibHB because it ruins everything. gotta close HB from task manager. and it stops the queue from going on.

I'll wait for new version of x265 - whenever it comes - then I'll update the thread. Thanks for your hard work, sir.

Thank you very much.
