FFmpeg cheat sheet for 360 video

FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

  • ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

DOS: TASM and C

How to combine Assembly and C in DOS

This gist is showing an example of C program calling routine written in assembly.

Some theory

  • C is case sensitive so it is necessary to use /ml switch in TASM
  • C compiler uses leading underscore (_) character for function names
  • parameters are passed to function in stack and integer return value is passed back in AX register
  • stack cleaning is done by caller

DOS: com vs exe

COM vs. EXE Program

EXE program can have any size whereas COM program can have maximally 64kB (just one segment).

COM Program

At the beginning of program there is program segment prefix (PSP). Because COM program is stored only in one segment so PSP occupies first 256 bytes (100h). Therefore start point begins at 100h. Values of segment registers are set to the begin of segment and don’t change during executing.

COM program in memory:
