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 :

ffmpeg.exe -rtsp_transport tcp -re -i rtsp://<username>:<rtsp://root:><password>@<mailto:root at>: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"
