No A/V/ delay taken into account

[frederic]

Hello,

First I installed the last version you gave me by mail. All results come from this version.

1 - Is the source file "corrupted" or anything coming from the file ?

1 - 1 - I encoded the same source file with avidemux (2.7.8) : the delay can be whatever you want : the result is a mp4 video sync file : the A/V delay was set to 0, and the A/V was fully sync.
 (BTW the source file is here : https://1fichier.com/?vp6nr0twqao89rm9acc6&af=22123 )

1 - 2 - I split the source file to cut it after around 1 min 30 s, since I realized that the sample I provided could not serve as a reliable test. There was not enough video to see.

Here is the new sample : https://1fichier.com/?1vkirot8ko7jox2ui7q7

The output file encoded with Hybrid is : https://1fichier.com/?wvkkha9t1xt1p8yv2ouw

The procedure I followed is just above :

1. I launch Hybrid
   
2. I drap/dropped the new sample source file in the Base field
   
3. I turned to Custom for the audio
   
4. In Audio : I saw that the Fr audio has a 1000 delay and and the second track (en) has 0 delay
   
5. I reload my parameters for encoding the audio (->Apply the currently selected profile)
   
6. The audio 1st track is selected (Fr) : I put 0 as delay A/V; then I hit the return key (to be sure the 0 is taken)
   
7. I added the track for encoding (I click on the + : -> Add current)
   
8. I returned to the Base and add a name for the video output : -> Set Output File
   
9. Base / Add to queue
   
10. Jobs : Start
    

Here is a copy/past of the just after putting a 0 delay for the audio track : (point 4)

Here is a copy/past of the MP4Box, after the encoding, so at the end :

I disabled "Jobs->Queue->Minimize job command lines" to look at the created job calls, and especially to the MP4Box call :

MP4Box -add "/Users/Famille/Films-Apple/2021-09-25@16_40_24_6910_04.264"#video:fps=24000/1001:delay=50:name="":lang="" -brand avc1 -add "/Users/Famille/Films-Apple/iId_2_aid_0_lang_fr_ms_2021-09-25@16_40_24_6910_02.aac"#audio:name="":lang="fr" -mpeg4 -itags tool="Hybrid 2021.09.24.1" -tmp "/Users/Famille/Films-Apple" -new "/Users/Famille/Films-Apple/_2021-09-25@16_40_24_6910__06.mp4"

See the result file around 1min 20 s. No sync between the audio track and the video... There is exactly 1s delay. See that with either VLC nor SMplayer.

NB : to split the file, I used MKVToolNix.
NB2 : previously, when I encoded the wall source file with 0 delay, I used MKVToolNix to sync the result file, and to produce another mp4 sync file (with a 1000 delay with ToolNix).

2 - Hydrid tests

I used another source file, with just one audio track, and without delay (0).
The procedure I used is the following :

1. I cleared all jobs in Hybrid (Jobs : Remove All)
   
2. I drag/dropped the new source file
   
3. The audio was already set to Custom
   
4. The encoding parameters were set too. I clicked on Add current
   
5. I returned to Base : I put a name for the output video
   
6. Then I clecked on Add to queue
   
7. I went to Audio : click on Clear
   
8. I set 1000 in the field A/V Delay, hit the return key
   
9. I clicked on the Add Current
   
10. I returned to Base : I put another name for the video output
    
11. I clicked on Add to Queue
    
12. Jobs : Start
    
13. I disabled "Jobs->Queue->Minimize job command lines" to look at the created job calls, and especially to the MP4Box call
    

For the 1st job : (delay 0)

MP4Box -add "/Users/Famille/Films-Apple/2021-09-25@19_11_07_6910_04.264"#video:fps=25:delay=50:name="":lang="" -brand avc1 -add "/Users/Famille/Films-Apple/iId_2_aid_0_ms_2021-09-25@19_11_07_6910_02.aac"#audio:name="":lang="" -mpeg4 -itags tool="Hybrid 2021.09.24.1" -tmp "/Users/Famille/Films-Apple" -new "/Users/Famille/Films-Apple/_2021-09-25@19_11_07_6910__06.mp4"

For the 2nd job : (delay 1000)

MP4Box -add "/Users/Famille/Films-Apple/2021-09-25@19_11_51_5210_04.264"#video:fps=25:name="":lang="" -brand avc1 -add "/Users/Famille/Films-Apple/iId_3_aid_0_DELAY_950ms_2021-09-25@19_11_51_5210_02.aac"#audio:delay=950:name="":lang="" -mpeg4 -itags tool="Hybrid 2021.09.24.1" -tmp "/Users/Famille/Films-Apple" -new "/Users/Famille/Films-Apple/_2021-09-25@19_11_51_5210__05.mp4"

The 1st video is sync, of course.

The 2nd video is correct too !!


Hope this helps for you to see whats wrong.
