crop, rearrange middle of video frame with ffmpeg
14 juin 2021, par GavrielI have a few hundred video files from a security camera. Let's say here's the full frame :



+---------------------+-------------------------+
| 2018-10-10 03:02:12 | |
+---------------------+ |
| +--------------+ |
| | IMPORTANT | |
| +--------------+ |
| |
+-----------------------------------------------+




I have 2 areas that I want to keep : the date and the inner box.
I know how to crop to either of them, for example :



ffmpeg -i in.mp4 -filter:v "crop=1120:320:40:60" -c:a copy out.mpg




However what I'd like to be able to do is to rearrange the frame to get this in the output :



+---------------------+
| 2018-10-10 03:02:12 |
+------+--------------+
| X X X| IMPORTANT |
+------+--------------+




(X X X would be just black, or if that's hard to do then it can be whatever part of the original video)
Any idea how can I do this ?

ffmpeg posting to nginx hangs after 90 minutes
22 octobre 2018, par Harnek GulatiI’m using a very simple program to push an ffmpeg stream from my raspberry pi camera to a nginx server. However, it fails after 90 minutes, with almost every single Raspberry Pi I use (I have this code on 12 Raspberry Pis).
Here is my ffmpeg command :raspivid -o - -t 0 -w 640 -h 480 -fps 25 | ffmpeg -re -i - -vcodec copy -hls_time 4 -f hls -hls_list_size 5 -hls_wrap 5 -threads 0 -timeout 5000 -max_reload 20000 -method PUT http://{}:{}/live/{}
And here is my configuration for nginx.conf :

how to remove duplicated frame from 00:00:00,00 to 00:00:00,25 section not overall with mpdecimate filter ?
19 octobre 2018, par cool jobshow to remove duplicated frame from 00:00:00,00 to 00:00:00,25 (00frame 25frames)section not overall with mpdecimate filter ??
normally H264 video have some duplicated frames on video start section ..i have tried like this ,
1) ./ffmpeg -i cated_2-3.UMMJI.MTS -map 0:0 -c:v prores_ks -profile:v 1 -qscale:v 8 -s 1920x1080 -r 29.97 -top 1 -c:a pcm_s16le -map 0:1 -filter:a:0 "pan=mono|c0=c0" -map 0:1 -filter:a:1 "pan=mono|c0=c1" -metadata:s encoder="Apple ProRes 422 LT" -filter_complex "[0]split=2[a][b];[a]trim=end_frame=26,mpdecimate[a];[b]trim=start_frame=25,setpts=PTS-STARTPTS[b];[a][b]concat=n=2:v=1:a=0" -vsync vfr -vf blackdetect=d=0.1:pix_th=.1 cated_2-3.UMMJI_MTS_mpdecimate26_section.mov
and tried to check black_frame on out prores mov file
2)./ffmpeg -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov -vf blackdetect=d=0.1:pix_th=.1 test.mov
then , will be shown like below
macmini-master:1. two_file_test khan$ ./ffmpeg -i cated_2-3.UMMJI_MTS_mpdecimate26_section.mov -vf blackdetect=d=0.1:pix_th=.1 test.mov

this MTS file have 19 duplicated frames !
also i have checked in FCPX and count how many dupicated frame on out prores mov file ...
