Our panel for AME doesn't work properly in audio mapping for sequential jobs

Report · Dec 06, 2021

Hi,

We've developed the AME panel take the encoding job from our desktop app(Mac/Windows) and process it as @Bruce Bullis advised last year.

It's really helpful.

We would like to thank Dan too.

Unfortunately, Our panel has two problems sometimes(one is major, and another is minor).

Firstly, under the situation like below output's audio mapping doesn't work correctly. Let me explain the situation the problem occurs.

versions:

# AME 15.4.1(build 5)

inputs:

#video1 (XD4C.MXF)

XDCAM HD422 MXF, 4 x mono audio

#video2 (XD8C.MXF)

XDCAM HD422 MXF, 8 x mono audio

presets(The forum can't accept .epr files, so they're attacted as .docx):

#preset1 (Apple ProRes 422 LT_4CH.epr)

for 4 x mono audio input(#video1)

#preset2 (Apple ProRes 422 LT_8CH.epr)

for 8 x mono audio input(#video2)

the situation :

1. Our desktop app sends #video1/#preset1 info to the panel and the panel runs the code below

csLib.evalScript(`app.getFrontend().addFileToBatch('/Users/admin/Documents/AME-REST/XD4C.MXF', 'Apple ProRes 422 LT_4CH', '/Library/Application Support/Adobe/CEP/extensions/com.malgn.ame-rest-service/preset/Apple ProRes 422 LT_4CH.epr', '/Users/admin/Documents/AME-REST/output/test')`, res => console.log(res));



csLib.evalScript(`app.getEncoderHost().runBatch()`, res => console.log(res));

=> The output is created by 'Apple ProRes 422 LT_4CH.epr' successfully(4 X mono -> 4 X mono).

2. Our desktop app sends #video2#preset2 info to the panel and the panel runs the code below

csLib.evalScript(`app.getFrontend().addFileToBatch('/Users/admin/Documents/AME-REST/XD8C.MXF', 'Apple ProRes 422 LT_8CH', '/Library/Application Support/Adobe/CEP/extensions/com.malgn.ame-rest-service/preset/Apple ProRes 422 LT_8CH.epr', '/Users/admin/Documents/AME-REST/output/test')`, res => console.log(res));



csLib.evalScript(`app.getEncoderHost().runBatch()`, res => console.log(res));

=> We tell the panel to use 'Apple ProRes 422 LT_8CH.epr', but it creates output has 4 X mono audio like the job before(8 X mono -> 4 X mono, we want to same 8 X mono audio as output).

Additionaly, if we tried .epr with 2 X Mono Audio setting before it, it creates output has 2 X mono audio(8 X mono -> 2 X mono).

It seems like the second job use the .epr right before, but log from AME said us it uses the proper preset file.

*attached translation for Korean in parenthesis

We don't think threre's a problem in the preset file, It doesn't occur when we do same thing manually with mouse, not through the panel.

when we use XDCAM HD422 preset with same audio preset, it works well like below.

Lastly, after we clean the queue manually, job request from the panel always fails. We must restart AME.

Please let us know if you have solutions.

Thanks.

We're investigating a potential problem in the sample panel...

Report · Aug 29, 2022

Is there anything you've found?

Report · Aug 31, 2022

Since last posting, we did find an issue where AME applied the .epr file from the last programatically added render job, to all pending jobs. That was fixed in 22.5.

Can you reproduce the issue you've described [above], in today's PPro beta?

It works well!

We've tried again with the same enviroment to test with the new version.

Thanks Bruce!
