Nginx rtmp module - on_publish fires multiple time instead of once
29 juillet 2017, par Stephen WrightThis is copy and pasted from the bug report I created on the rtmp-module by Arut, I am not completely sure if it is a bug or me not understanding how the module works, I have read the whole directives of module as from https://github.com/arut/nginx-rtmp-module/wiki/Directives
Proper explanation, if code is not displayed properly I will edit and fix
Hi, been using the module and finding it very very good !
Think I have found a issue though, although it may be me misunderstanding the directives.
Essentially I wish to fire a script (/usr/local/bin/make_thumbnail.sh) which creates a thumbnail automatically from a stream (using ffmpeg), the idea is to have this done for every stream as soon as it is published in order to create a function a bit like twitch tv where the streamer will not have to specify any thumbnail image, authenticated users simply start a stream (which will later be authenticated but is not yet) The script does also write data into the database however this stage works fine and I don’t believe the issue is related, if I comment out these lines then the thumbnail creation still works and my issue continues.
Initially this was done using the "exec" command as I believe I mis-read the documentation and I believe the exec command doesn’t work for my problem as ". When publishing stops the process is terminated." does this mean it will continually execute until stream stops ?
I have started using the exec_publish command to try and fix this issue however the same issue seems to occur. The entire script repeats approximately every 15-17 seconds, a new thumbnail is created and a new database entry is create with all the correct information.
Below is the nginx.conf line. Please ignore if indentation is incorrect couldn’t see a way to indent blocks of code and it’s late here, assume all code is indented correctly unless you believe that could be the issue in which case I will post it indented as early as I can.
application live {

#on publish create thumbnail using first second of stream and save in
/var/stream/video_recordings/thumbnails
exec_publish usr/local/bin/make_thumbnail.sh $name;The rest can be pasted or attached if needed but is working nginx config for rtmp + website
The most simple version of the make_thumbnail..sh is pasted below, I have omitted the variables that I have used for database entryys obviously but as the script works without fail from terminal I believe this to be an nginx issue (if I run the command manually under the nginx user e.g. sudo -u nginx /usr/local/bin/make_thumbnail.sh with a name the same as any running stream, it works and only executes once as would expect, all permissions in script are ok and tested.
make_thumbnail.sh

echo "time: "

strftime 1 /var/stream/video_recordings/thumbnails/"$FILENAME.jpg";
#Writes path to video into database

INSERT INTO $TABLE3 (thumbnailfile) VALUES ('$FILENAME');
set @last_id_in_thumbnails = LAST_INSERT_ID();
INSERT INTO $TABLE (created_at, updated_at, thumnailID) VALUES
(NOW(),NOW(),@last_id_in_thumbnails);
SET @last_id_in_livestreams = LAST_INSERT_ID();
INSERT INTO $TABLE2 (created_at, updated_at, filename,liveID) VALUES
(NOW(),NOW(),'$FILENAME',@last_id_in_livestreams);
EOFI have not got the nginx rtmp logs installed, I can obviously do this however some of the logs appear in the nginx error.log, strangely the latest stream I tried did not update in the access log, however I think this is because I did not attempt to connect to it via any method. I don’t fully understand the error.log, in my stupidity I decided to use nginx with which I am quite inexperienced and I am finding it very difficult to troubleshoot this issue, it appears to me that as part of the RTMP protocol or my streaming software (OBS) is either directly pinging the rtmp stream or is being pinged by the server to ensure the connection is still there. And this ping is
I have left a stream running from approx 4 minutes without interacting with the server, streaming software, computer running the stream, I have ensured the internet connection is constant as my first though was the connection dropped, however on inspecting the database the executing is done always after at least 11 seconds however usually this is 16, I can’t seem to figure out how to select the closest dates from the database however there has been at least a few 17 second differences (potentially when
I am unsure if this is an issue or if it is intended behavior but I do require this to finish a university degree, I’m not asking for answers but if it is a legitimate issue then I would be happy to spend as much time I can commit to it if some insight into what is causing it, or if there is a workaround I believe it should be documented somewhere, I have googled into making any exec commands run only once on publishI can’t seem to pinpoint where in the log the issue is happening however think it is something to do with the below exceprts I would attach the file but can’t seem to select all lines after the timestamp upon starting a stream

Evolution #3751 : Ajouter le support du SNI au proxy connect

FFmpeg - Concatenating videos with different resolutions
7 août 2017, par JillI currently have an android app where the videos get combined using ffmpeg’s concat. That works fine. However, when I add text (using drawtext) to one of the videos, after combining the videos again, the combined video gets distorted. The video with the drawtext shows up fine, but then the videos without text switches orientation.
I think the problem roots from the fact that a vertical video on my android phone has the resolution of 1920x1080, however if I use that for the scale when executing drawtext, it becomes horizontal.
I think an example might help explain this better. Let’s say I have 2 vertically recorded videos, and I combine them with concat. The combined video shows up fine. Then if I add text to the 1st video using drawtext, the combined video will then show the first video (with text) at normal orientation (vertical). However, when it transitions to the next video, it first stalls for a couple seconds and then the 2nd video is shown at a horizontal orientation.
Also, I tried this also with having the aspect ratio as 1:1 so it wouldn’t matter, but the second video’s orientation still changed counter clockwise.
Thanks for the help, and happy to add more clarification if needed.
This is for adding the text :
ffmpeg -i input.mp4 -vf drawbox=y=ih-200:color=black@0.5:width=iw:height=200:t=max
,drawtext=fontfile=RobotoRegular.ttf:text='Text':x=(w-text_w)/2:y=(h-text_h)-100:fontsize=70:fontcolor=white
