No A/V/ delay taken into account

[frederic]

What does "Base->Show All Data" report about the file, I supect that the file is correctly analysed, but there is a small bug/typo in Hybrid, but I need a sample to reproduce and debug this.

Do you have any idea to overcome this problem ?

Once I can reproduce it, I can fix it.

What can I do for you ?

Here is a sample of the source file. As mentioned, a 1000 delay is written witin the file, but no delay has to be taken into account for a proper sync A/V mp4 file.

What I did:

• Started Hybrid
  
• Loaded the file.
  
• Looked at the delay audio data of  first track (Base->Audio->A/V delay)  and it showed 1000.
  
• Switched 'Base->Processing->Audio' to 'custom'.
  
• Switched tp the second audio track (by setting 'Base->Stream Selection->Audio' from '1 - fr' to '2 - en'
  
• Looked at the delay audio data of the second track (Base->Audio->A/V delay)  and it showed 0.
  
• Added the first audio track to the audio queue (Audio->Base->Add current)

• I then sat an .mp4 output file (Base->Output file) and let Hybrid create a job (Base->Add to queue).
  
• Then I disabled "Jobs->Queue->Minimize job command lines" to look at the created job calls.
  

I then copied the MP4Box muxing call and split it up to better see what happend with the delays:
(Note that since mp4 does not support negative delays all stream delays get adjusted by the most negative delay.)

OK, and what about the film, you can display with SMplayer ? Is the audio sync with the video ? Especially when the ball is touching the groundfloor (about 45-50 s) ?
I will do all those lines, as you did them. And will come back later.

I looked at the file with MPC-HC (on Windows).
Both streams of the input clip are synch here.
Clip produced the way I wrote above (+ I set video to passthrough, to not having to reencode the video) also is sync for all four audio streams.
Haven't used SMPlayer for ages.

I will do all those lines, as you did them. And will come back later.

Remember to properly write down what you do exactly.

I found one thing that 'broke' in one of the last few releases and that is that changing the audio title in the Base-tab, did not change the audio title in the Audio-Tab. May be that is related to your issue.
I suspect I broke this when I change fixed some issues with batch handling, not sure whether this broke that again, we will see.
Will compile a dev version and send you a link via pm. (send link)

Many thanks in advance.
Waiting for that dev version.
I'll continue to see what is wrong whether in the file (with other encoders) nor in my procedure.
