From 17046fc1adc40ffe227a30679f6402829edc27ac Mon Sep 17 00:00:00 2001 From: =?utf8?q?V=C3=ADctor=20Manuel=20J=C3=A1quez=20Leal?= Date: Wed, 22 Dec 2021 18:13:17 +0100 Subject: [PATCH] jpegformat: Use codecparsers' for JPEG markers. Instead of repeating JPEG markers definition, this patch uses those defined in gstcodecparsers library.
