TO CHOOSE MPEG-4 Part 2 PROFILES IN TERMUX FFMPEG

Ffmpeg chooses simple profile as default profile of MPEG-4 PART 2.
This is how to write the options;
Generally; [-profile:v n];
Or n can be n(one below 0,1,2 etc)+16 multiples, where by;
1. Simple Profile, n=0
2. Simple Scalable Profile, n=1
3. Core Profile, n=2
4. Main Profile, n=3
5. N-bit Profile, n=4
6. Scalable Texture Profile, n=5
7. Simple Face Animation Profile, n=6
8. Basic Animated Texture Profile, n=7
9. Hybrid Profile, n=8
10. Advanced Real Time Simple Profile, n=9
11. Code Scalable Profile, n=10
12. Advanced Coding Profile, n=11
13. Advanced Core Profile, n=12
14. Advanced Scalable Texture Profile, n=13
15. Simple Studio Profile, n=14
16. Advanced simple profile, n=15

N.b: ffmpeg technically ignores all of these instead it use simple profile only. If you need use b-frames to force ffmpeg.
