Good day!

I have a ffserver instance for rtsp broadcasting. And after ney year port upgrades, ffserver segfaults on client rtsp connection.
I'm google about that issue, and it already known: https://trac.ffmpeg.org/ticket/5869
Is it possible to fix version in ports please?

Thanks! I do a PR and that patch helps me. One moment I want to ask:
I'm create a patch file
/usr/ports/multimedia/ffmpeg/files/patch-ffserver_config.c
Code: 
--- a/ffserver_config.c.orig
+++ b/ffserver_config.c
@@ -320,6 +320,8 @@ done:
     av_dict_free(&recommended);
     st->recommended_encoder_configuration = enc_config;
     st->codec = av;
+    st->codecpar = avcodec_parameters_alloc();
+    avcodec_parameters_from_context(st->codecpar, av);
     stream->streams[stream->nb_streams++] = st;
 }
But on make patch it ask me which file to patch, I'm tell him ffserver_config.c and it works, but why it ask? I'm do patch file similar as other patches...
 
When creating names for patch files, replace each underscore (_) with two underscores (__) and each slash (/) with one underscore (_). For example, to patch a file named src/freeglut_joystick.c, name the corresponding patch patch-src_freeglut__joystick.c. Do not name patches like patch-aa or patch-ab. Always use the path and file name in patch names. Using make makepatch automatically generates the correct names.
