Hope everyone had a wonderful thanksgiving!
(motion Version 4.0.1)
I've a pi3 with 7 cameras, if all them are triggered at the same time,
I may experience oom:
Nov 28 22:00:34 pi3 kernel: [ 1053.644315] Out of memory: Kill process
4432 (motion) score 398 or sacrifice child
Nov 28 22:00:34 pi3 kernel: [ 1053.644360] Killed process 6331 (ml7)
total-vm:1006252kB, anon-rss:360900kB, file-rss:288kB, shmem-rss:0kB
Nov 28 22:00:34 pi3 kernel: [ 1053.743129] oom_reaper: reaped process
6331 (ml7), now anon-rss:4kB, file-rss:0kB, shmem-rss:0kB
I was trying to have motion write just a raw file so I can dispatch
it to my other hosts for processing. (Just to spare my pi from running
the expensive ffmpeg operations.)
ffmpeg_output_movies on
ffmpeg_output_debug_movies off
ffmpeg_timelapse 0
ffmpeg_timelapse_mode daily
ffmpeg_bps 400000
ffmpeg_variable_bitrate 0
ffmpeg_video_codec mp4
ffmpeg_duplicate_frames true
use_extpipe on
extpipe cat > %f.raw
;extpipe ffmpeg -y -f rawvideo -pix_fmt yuv420p -video_size %wx%h -re
-i pipe:0 -use_wallclock_as_timestamps 1 -vcodec libx264 -preset
ultrafast -movflags +faststart -an -f mp4 %f.mp4
While experimenting with these config settings, I noticed that it
still writes out an mp4 file:
-rw-r--r-- 1 evu evu 22M Nov 28 12:43 cam3-2019-11-28-12-43-12-01-00.raw
-rw-r--r-- 1 evu evu 1.6M Nov 28 12:44 cam3-2019-11-28-12-43-12-01-00.mp4
is it possible to have just the raw file written out, not along with
.mp4 in my case?
Thanks!
