Output should be:
- 2,5 Mbit/s CBR H.264/mpeg4
- Audio 128kbit/s joint stereo mpeg2
Command i am using as last looks like this, and stream is not CBR.

Try

Added nal-hrd=cbr to x264opts and removed 8x8dct which is used in High profile.
If your input is interlaced, deinterlace it (add yadif filter).

What I am interested in is the automatic creation of a master playlist using ffmpeg in this command.

I'm using ffmpeg to produce several HLS variant playlists from an .mp4 file. When I check master.m3u8 file with mediastreamvalidator I get:
Error: Measured peak bitrate compared to master playlist declared value exceeds error tolerance
I understand that the error percentage needs to be less than 10%, and figured it out on 1 variant but not the three others. I've spent quite a bit of time adjusting the -maxrate and the -buffsize but the error percentage change is minimal. Beginning to wonder if I'm misunderstanding something?

Any help would be greatly appreciated on the -maxrate and -buffsize for variant playlists 0, 1, and 2. No adjustment I make seems to make any difference.
I have successfully output 3 HLS output using -map 360, 720 & 1080p. My source file is 540p. once generated I use ffprobe on the newly created 360.ts, 720.ts, and 1080.ts and notice that there is a second video channel. This channel is the input video. How do I have FFmpeg not output the original video as part of the output?
this is the ffprobe on 360.ts

thank you.
1) -map 0 will include all original streams, including the video. Change to -map 0:a
2) You don't need to scale to 720p twice. scale once and split.
3) b:v and crf are exclusive in libx264 (h264 encoder). Pick one (crf is preferable)
Use

I've been banging my head for 2 days now. I can currently output 3 M3U8 "HLS" outputs resized but now I need to add an overlay to each output. The overlay image would need to be resized as well. My take on this is that the image should be applied to the source and then the 3 outputs can be generated. I have read that -vf cannot be used since there are 2 inputs. Here is what I am currently using which works.
How could I add an image overlay?

Any advice would be greatly appreciated.
Thanks in advance.
You need to use a filter_complex for the overlay filter, and then splitting the result into 3 and scaling each copy:
ffmpeg -hide_banner -y -i input.mov -i image.png
-filter_complex "[0][1]overlay,split=3[a][b][c];[a]scale=w=640:h=360:force_original_aspect_ratio=decrease[a];[b]scale=w=1280:h=720:force_original_aspect_ratio=decrease[b];[c]scale=w=1920:h=1080:force_original_aspect_ratio=decrease[c]"
-map "[a]" -map 0:a -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 800k -maxrate 856k -bufsize 1200k -b:a 96k -hls_flags single_file 360p.m3u8
-map "[b]" -map 0:a -c:a aac -ar 48000 -c:v h264 -profile:v main -crf 20 -sc_threshold 0 -g 72 -keyint_min 72 -hls_time 4 -hls_playlist_type vod -b:v 2800k -maxrate 2996k -bufsize 4200k -b:a 128k -hls_flags single_file 720p.m3u8

(If your h264 encoder is x264, b:v has no effect when used with crf, but maxrate and bufsize do.)
