Comment (by nls):

 I tested some more. It seems the issue is more complicated. It's not
 exclusive to the h264_v4l2m2m encoder so the title might need to be
 changed. The following command produces the same buggy master.m3u8 as the
 one in OP:

 {{{
 ffmpeg -i result.mp4 -f hls -hls_playlist_type event -hls_segment_filename
 segment_04_%06d.ts -master_pl_name master_04b.m3u8 -hls_time 6 -c:v copy
 stream_04b.m3u8
 }}}

 No matter what ffmpeg version, the CODECS attrib is omitted. I tried git
 master, an OMX-enabled version from a year ago, and the 5.1.1 release. My
 guess is that some inputs seem to provide the necessary info for adding
 the attribute, and some don't. So it's a lot more complicated to handle,
 probably. h264_omx and libx264 encoders, on the other hand, do produce a
 correct master.m38u, CODECS included.
