From e6754d2ad20c918735d3bf5cc8122ac57f53d03c Mon Sep 17 00:00:00 2001 From: Derek Buitenhuis Date: Mon, 2 Aug 2021 21:50:44 +0100 Subject: ffprobe: Rename Audio Service Type 'type' field to 'service_type' 677a030b26045acb50353d7954ae984ceefcd807 introduced more printable side data types in ffprobe, however the Audio Service Type side data 'type' field that was introduced aliases an existing field of the same name within the side data array, which can lead to JSON output like: "side_data_list": [ { "side_data_type": "Audio Service Type", "type": 0 }, { "side_data_type": "Stereo 3D", "type": "side by side", "inverted": 1 } ] This, while technically valid JSON, is considered bad practice, since it forces all downstream users to manually parse it and check all types; it makes simple deserialization impossible. Worse, in som loosely type languages, it can lead to silent bugs if exising code assumed it was a different type. As such, rename this second "type" field to "service_type".
