Records With Large Size didn't convert to MP4 on BBB 2.6

[SepehrTorahi]

I have problem with records that have large size
They don't convert to mp4 , but at the same time other records convert very well and i can download them.
Also when i used bbb-mp4.sh to convert them manually i had the same problem, it's not successful.
I tried to rebuild them but it's not helpful.
I Need Help :)

@SepehrTorahi What is the duration of the recordings?

I try to convert a recording of around 2hours , and i get the following error :

Starting pulseaudio...
Waiting for pulseaudio to start...
Recording found
Error: Evaluation failed: TypeError: Cannot read property 'duration' of null

I wanna also ask if a video length is for example 1 hour, does it take 1 hour for ffmepg to convert it to mp4 ? as it should open it in chrome and record it.
Thank you !
