No A/V/ delay taken into account

Looking at HybridDebugOutput_1:

2021.09.23 - 08:33:35_macOS 10.15 (64bit)_2021.07.18.1 - level 9: adding(1): /Users/Famille/Downloads/The.Suicide.Squad.2021.MULTi.TRUEFRENCH.1080p.WEB.H264.WwW.ZoNe-TelecharGement.CaM (1).mkv;0;aac;6;bitrate;192;FDK;low complexity;48000;3.00;fr;-50;7966.080;ac3;0;0;toStereo (dpl2);;false;;false;2;false;;;;false;false;;;false;48000;0;ac-3;;false;true;false;3/2/0.1;1/1;;0;0;;None;54:_:15;10;20;0;1000;;false;;pcm;false;1;;;;;;16;-n;4;GPU;NVIDIA CUDA;;6;false;/Users/Famille/Downloads/The.Suicide.Squad.2021.MULTi.TRUEFRENCH.1080p.WEB.H264.WwW.ZoNe-TelecharGement.CaM (1).mkv;true;false;;;false;2;;;-1;

-> delay is set to -50 (due to encoder delay), so far everything looks correct.

Looking at HybridDebugOutput_2:

Audio extraction call:

mkvextract tracks "/Users/Famille/Downloads/The.Suicide.Squad.2021.MULTi.TRUEFRENCH.1080p.WEB.H264.WwW.ZoNe-TelecharGement.CaM (1).mkv" 0:"/Users/Famille/Films-Apple/iId_1_aid_0_lang_fr_DELAY_-50ms_2021-09-23@08_35_14_5110_01.ac3"

looks correct.

Audio encoding call:

ffmpeg -y -threads 4 -loglevel fatal -nostdin -i "/Users/Famille/Films-Apple/iId_1_aid_0_lang_fr_DELAY_-50ms_2021-09-23@08_35_14_5110_01.ac3" -t 02:12:06.635 -ac 6 -ar 48000 -f sox - | sox --multi-threaded  --temp "/Users/Famille/Films-Apple/2021-09-23@08_35_14_511001" --buffer 524288 -S -t sox - -b 16 -t wav - remix -m 1v0.3254,3v0.2301,5v0.2818,6v0.1627 2v0.3254,3v0.2301,5v-0.1627,6v-0.2818 gain -n 3.00 | fdkaac --bitrate 192000 --profile 2 --transport-format 0 --gapless-mode 2 --ignorelength -o "/Users/Famille/Films-Apple/iId_1_aid_0_lang_fr_DELAY_-50ms_2021-09-23@08_35_14_5110_02.aac" -

looks fine too.

Muxing call:

MP4Box -add "/Users/Famille/Films-Apple/2021-09-23@08_35_14_5110_04.264"#video:fps=24000/1001:delay=50:name="":lang="" -brand avc1 -add "/Users/Famille/Films-Apple/iId_1_aid_0_lang_fr_ms_2021-09-23@08_35_14_5110_02.aac"#audio:name="":lang="fr" -mpeg4 -itags tool="Hybrid 2021.07.18.1" -tmp "/Users/Famille/Films-Apple" -new "/Users/Famille/Films-Apple/_JOBID.mp4"

Looks fine too. (-50ms -> video is delayed by 50ms)

Looking through HybridDebugOutput_3 there are no error or similar that would explain the problem.

All the calls look fine.

Have you another source? Might be an issue with the source file.
-> If you enable "Config->Automation->On Load->Always extact time codes from input" before loading the source Hybrid will extract the time codes and check whether they indicate that the source is vfr even when MediaInfo reports the source as cfr.
Ignored time codes could be an issue, other than that I see no problem in the way Hybrid is processing the source.

Yes, everything looks fine. I agree.

I did the same test with another source file (I mentioned it previously, see above),since this source file could be corrupted. With another source file, without delay (delay 0 in the metadata), the encoded video is fine with 0 as A/V delay; this video reencoded with 1000 ms of delay produces a file without delay, like the file with 0 delay. So it seems as if the field "A/V delay" is not read in the frontend, and takes what is is written in the metadata, when loading the source file at the very beginning.

I will test the tip you gives just here. I will come back again.

The tip did not solve the problem.

Do you have any idea to overcome this problem ? Is it due to the program that does not retrieve settings you give in parameters in command line?
