 Summary of the bug:

 It seems the commits in the git master around
 14fa0a4efbc989619860ed8ec0fd33dcdae558b0
 now prevent the normal use of the api.  The following is a sample that was
 previously functional for setting up a MP4 container with HEVC.

 #include <libavformat/avformat.h>
 int main (int argc, const char **argv) {

     AVFormatContext *format_context;

     format_context = avformat_alloc_context();
     format_context->oformat = av_guess_format("mp4", NULL, NULL);
     format_context->oformat->video_codec = AV_CODEC_ID_HEVC;

     avformat_close_input(&format_context);

     return 0;
 }


 Compiler message:

 error: assignment of member ‘video_codec’ in read-only object
      format_context->oformat->video_codec = AV_CODEC_ID_HEVC;
