[OT][AE+Deadline] rendering breaks on AEGP Plugin PNGIO Support: PNGIO library error: buffer error

[christian]

hello
and sorry for the OT, but somehow there doesn't seem to be much info out on the net regarding similiar things...

when using deadling to render an after effects comp, some of our blades will randomly throw an error and finish their task.. its never the same machine, also never the same frame, meaning if you requeue the task on the same blade it will then render just fine, so we can never pinpoint if its a certain plugin/configuration/etcwhatahaveyou..

more annoying it will show up as an error in the task log file, but not in the deadline monitor, meaning it will show your job as 100% finished with zero errors, yet when you load your rendered pictures in, you suddenly get "12 frames missing from this sequence" stuff..

comps themselves are nothing too heavy usually apart from resolution (like 12k x 1k or 6k x 4k) and often just use standard AE plugins with maybe some trapcode stuff on top..

here the paste from the log..

0: STDOUT: INFO:After Effects: AEGP Plugin PNGIO Support: PNGIO library error: buffer error

0: STDOUT: INFO:After Effects: AEGP Plugin PNGIO Support: Unable to create PNGIO.

0: STDOUT: PROGRESS: 25.03.2015 18:00:17: Finished composition Final .

0: STDOUT: PROGRESS: Total Time Elapsed: 3 Min, 10 Sec

0: STDOUT: WARNING:After Effects warning: logged 2 errors, please check log. First error was AEGP Plugin PNGIO Support: PNGIO library error: buffer error (5027 :: 12)

0: STDOUT: _glmFindMaterial(): can't find material "None".

0: STDOUT: LoadLibrary "n" failed!

0: STDOUT: LoadLibrary "n" failed!

0: INFO: Process exit code: 0

thanks for any pointers...

have your comps got repeat-tile or motion tile effects, we had similar probs (thought not with deadline) when rendering comps that had supported hi rez images (20000 px wide)

but that were then mirrored, it was an image plane/buffering thing, but reported errors as image IO problems....

 

solution was to cut layers into smaller tiles
