  • Swift : How can I generate Mp4 video from programmaticall output ? [closed]

    21 août 2020, par Mount Ain

    This question is specifically to Swift programming language for Linux & macOS platforms.To understanding the concept, I used Swift programming language. But not depend on Swift programming language. C or C++ is also good to me.

    


    I can generate JPEG image from NSView by using NSBitmapImageRep. But Linux I don't what I want to do. So, the first thing I need to know is the step to generate JPEG image by programmatically without using the NSView. I really don't know How hard it is. But I want to learn how it's work. I feel It's the way to fill the color into pixels one by one to combine a Image. But I don't know How to do in programming. I knew the same way is used in videos by packing the series of image with audio & subtitle & other meta info.

    


    If you ask about compression, I really want to know How Twitter & YouTube compressing uploaded videos without loss of quality.

    


    So what is the concept,

    


      

    1. To generate a JPEG image by programmatically without using NSView ?

      2. 


    2. To generate MPEG-4 video by group of JPEG images ?

      3. 


    


    Thanking in advance...

    I have this command that works perfectly fine :

    


    echo off
mkdir inputs
mkdir outputs
set "InputFolder=%~dp0inputs"
for /R "%InputFolder%" %%i in (*.mp4) do ffmpeg -i "%%i" -c copy "outputs\%%~ni.mkv"

    echo off
mkdir inputs
mkdir outputs
set "InputFolder=%~dp0inputs"
for /R "%InputFolder%" %%i in (*.mp4) do (ffmpeg -n -i "%%~ni.mp4" -i "%%~ni-eng.srt" -c copy -max_interleave_delta 0 -map 0 -map -0:v:1? -map -0:v:2? -map 1 -fflags +bitexact -map_metadata:g -1 -map_metadata -1 -metadata title="" -metadata comment="" -metadata:s:v title="" -metadata:s:v language="und" -metadata:s:v VENDOR_ID="" -metadata:s:a title="" -metadata:s:a:0 language="eng" -metadata:s:a:0 handler_name="English" -metadata:s:a VENDOR_ID="" -metadata:s:s:0 language="eng" "outputs\%%~ni.mkv")
