Hi,
I am sending you the entire details of the issue which I am facing in macOS in
the email body.
Transcoding problem in macOS:-
We have a MacBook application which has a screen recording feature as well as
capturing the user from Camera (In-built MacBook Camera or any external Camera)
who is using that application.
MacBook Model: MacBook Pro (15-inch, 2018)
macOS: High Sierra (Version: 10.13.6)
Processor: 2.2 GHz Intel Core i7
Memory: 16 GB 2400 MHz DDR4
Graphics: Intel UHD Graphics 630 1536 MB
The same application is also run on other macOS also: Catalina, Mojave,
El-Capitan.
The application has transcoding logic which converts a .mov file to .mp4 file.
The application converts two different .mov files to .mp4 files.
The .mov file which is related to Screen recording gets successfully converted
to .mp4 file
But the .mov file which captures the user does not get successfully converted
to .mp4 file
(This issue occurs in all the versions of macOS as mentioned earlier)
In both these cases, ffmpeg command is being used with some parameters. Along
with this command, a preset file is also being used.
Preset file description:-
vcodec=libx264
vprofile=main
level=30
b:v=800000
bufsize=800000
In the existing codebase, the following command tries to convert from .mov file
to .mp4 file:-
./ffmpeg -i Input0.mov -y -fpre ./preset/mp4_Projector.ffpreset -astrict -2
-vsync vfr -s 640x480 -loglevel verbose Output0.mp4
But the above command fails to convert the .mov file to .mp4 file.
We ran the exact command from terminal and got the following log
Verbose Log:-

Trying to solve with this anomaly, we googled some more commands related to
ffmpeg and tried with the following new command:-
./ffmpeg -i Input0.mov -y -fpre ./preset/mp4_Projector.ffpreset -astrict -2
-vsync vfr -s 640x480 -vf mpdecimate,setpts=N/FRAME_RATE/TB -loglevel verbose
Output0.mov.mp4
We ran the above new command from terminal again and got the following log:-

But when we tested with some other .mov files, this new command didn’t work.
And for all those files, we got the following logs:-

Conversion failed!
Even we downloaded the ffmpeg version 4.2.2 and ran the same commands. The
results were same.
We took the same .mov files which did not get converted to .mp4 file and used
Handbrake application to convert them. All of them got successfully converted
to .mp4 file.
Requesting assistance to mitigate this issue.
Thanks & Regards

Can you please post these logs directly in the email, and the problem

Sending word documents here is simply trolling.
