The attached patch allows segment muxer to be used for file archiving by
allowing it to automatically create the output directories. For example the
following should work as expected:
ffmpeg
...input_params...
-f segment \
-segment_atclocktime 1 \
-segment_time 5 \
-write_empty_segments 1 \
-segment_format_options movflags=+faststart \
-strftime 1
output_directory/mychannel/%Y/%m/%d/%H/%M/mychannel-%s-%Y%m%d-%H%M%S.mp4
The patch is against ffmpeg-3.3.6
