[FFmpeg-devel] Need to reduce size of ffmpeg.exe for version 5.0.1

[FFmpeg-devel] Need to reduce size of ffmpeg.exe for version 5.0.1

[Kumar, Rahul]

Hi Team,

We are working on a prototype which converts RTSP streams to HLS using ffmpeg transcoder.

We are using below ffmpeg command to convert RTSP to HLS :

cmd:-
ffmpeg.exe -rtsp_transport tcp -re -i rtsp://<username>:<rtsp://root:><password>@172.31.67.223<mailto:root@172.31.67.223>:554/axis-media/media.amp?videocodec=h264 -c:v libx264 -crf 21 -preset veryfast -c:a aac -ac 2 -f hls -hls_flags delete_segments -hls_list_size 4 -hls_time 1 -g 5 -sc_threshold 0 -hls_playlist_type event C:\Users\Niagara4.13\tridium\stations\HLSTest\shared\vids\-514225936\stream.m3u8


We downloaded "ffmpeg.exe(5.0)" from https://www.videohelp.com/software/ffmpeg .  We are also using FFmpeg 5.0.1 "Lorentz" (https://ffmpeg.org/download.html) libraries in our project.

Can somebody help me answering below questions :

1. Can we reduce the size of ffmpeg.exe ? Any idea how can we create a smaller ffmpeg.exe which should be able to run only above command  to convert RTSP to HLS? (as its size is 110 mb+ so it is difficult to ship it with our product).
2. Is there a way to run above ffmpeg command using "dll files" or other alternative instead of using "ffmpeg.exe"

I sent you an answer to a similar question the 13th of July, but you
didn't reply: http://ffmpeg.org/pipermail/ffmpeg-devel/2022-June/297489.html

1) You can compile ffmpeg from sources yourself. You can disable
components you won't use and use --enable-small in the configuration.
2) You can use the dll files by writing a program using them.
