I'm trying to record video and audio from an IP Camera streaming in H.264.
I found these different options:
-i "camera_url" -c:v libx264 -acodec copy "out.mp4"
-i "camera_url" -c:v copy -acodec copy "out.mp4"
-i "camera_url" -vcodec copy -acodec copy "out.mp4"
Could anybody tell me what's the difference between those 3 types of recordings? As far as I understand the last one doesn't do any transcoding so whatever comes from the camera is stored in the file. What about the other 2?
