GStreamer minimal required version must be increased up to `1.22` #3

Hi! After trying to build library on Ubuntu 22.04.4 LTS with GStreamer 1.20.3 , i spotted the next compilation error:

Gstreamer-H264-Encryption/gst-h264-encryption/src/h264_decrypt.c: In function ‘gst_h264_decrypt_before_nalu_copy’:
Gstreamer-H264-Encryption/gst-h264-encryption/src/h264_decrypt.c:159:31: error: ‘GST_H264_SEI_USER_DATA_UNREGISTERED’ undeclared (first use in this function)
  159 |       if (msg->payloadType == GST_H264_SEI_USER_DATA_UNREGISTERED) {
      |                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Its occured, since GstH264Parser :: GstH264SEIPayloadType::GST_H264_SEI_USER_DATA_UNREGISTERED was added since Gstreamer 1.22.

So, we need to increase minimal required GStreamer version in meson.build (currently there minimal version is 1.19)

Hi there,

Thank you for your interest in this project.

I tested on 1.22 and saw that writing H264 SEI is not supported yet. According to here, it is added on 1.23.1 as in the screenshot: image

Hence, I updated the minimum required version to 1.23.1 while merging your pull requests.

Best regards,
