From a92d8f8152cce3e349d21732248c6ccdecd000df Mon Sep 17 00:00:00 2001 From: Stefano Sabatini Date: Mon, 27 Mar 2023 02:22:28 +0200 Subject: [PATCH 1/3] doc/ffmpeg: slightly rework introductory examples In particular, add a sentence to introduce the example, and add a simpler starting example with no options. Also use different format for input.avi and output.mp4, to convey that the conversion also works on the container format.
