ffmpeg command not interpreted correcly from cron
16 avril 2022, par Andre Lörchneron my raspberry pi I'm trying to run a script every 30 minutes that restarts a video stream. Reason is the stream is consistently running into hickups after roughly 35 minutes and stops a few minutes after.
I tried fixing the root problem without any success so far, so an easier and valid workaround is to just restart the stream.


I created a script
restart_stream.shthat kills the previous stream and immediately starts it again.

#!/bin/bash

killall -r libcamera-vid ffmpeg
libcamera-vid -t 0 --framerate 30 --width 1280 --height 720 -b 2000000 -o - --nopreview | ffmpeg -f h264 -thread_queue_size 4096 -i - -f pulse -ar 44100 -ac 2 -acodec pcm_s16le -thread_queue_size 4096 -i default -vcodec copy -acodec aac -ab 128k -fflags genpts -fflags igndts -f fifo -fifo_format flv -map 0:v -map 1:a? -drop_pkts_on_overflow 1 -attempt_recovery 1 -recovery_wait_time 2 rtmp://a.rtmp.youtube.com/live2/<key>
</key>

cron job


*/30 7-19 * * * /bin/restart_stream.sh >/tmp/stream.log 2>&1


Running this script manually from the ssh console works perfectly fine but once I run it from cron it fails with the following error

FFMPEG failing in AWS Lambda
18 février 2019, par Zaid AmirI am trying to create a transcoding function for short videos. The function is hosted on AWS Lambda. The problem is that AWS lambda seems to be missing something that FFMPEG requires, at least according to Amazon.
I contacted Amazon earlier and this is their response to the issue :
We found that the FFMPEG operations require at least libx264 and an
acc library, both of which will have dependencies of their own. To
troubleshoot the issue it will involve diving deeper into the full
dependency chain. We can see that it works in the Amazon Linux
environment however, the environment is similar but not identical to
the lambda environment. There can be some dependencies that exist in
Amazon Linux but not in lambda environment as Lambda runs on the
container. Here, as FFmpeg is a third party software, diving deeper
into the dependency chain and verifying the version compatibilities is
very hard to do. Unfortunately going further, this is bound to go into
architecture and code support which is out of AWS Support scope 1. I
hope you understand our limitations. However should FFmpeg support
have any questions specific to the Lambda platform, please do let us
know and we will be happy to assist. We will be in better position to
investigate further once you receive an update from the FFmpeg support
suggesting an issue from Lambda end.Upon AWS suggestion, I contacted FFMPEG on the developers mailing list, my message was rejected with the reason being that its more suited to ffmpeg users mailing list than developers. I sent an email to ’ffmpeg-user@ffmpeg.org’ a week ago and did not get any response yet.
I then went and built a dynamically linked ffmpeg version making sure to package all libraries, checked ddl on each one, then made a small lambda function that looped over all binaries and ddled each one of them, compared that to the output I got from Amazon Linux and the same dependencies/versions exists on both lambda and the AWS Linux instance yet ffmpeg still fails on lambda.
You can find a detailed log file here : https://www.datafilehost.com/d/6e5e21bb
And this is a sample of the errors I’m getting, repeated across the entire log file :

ffmpeg -ss 00:00:02 -I file.mp4 -vframes 1 -y output.jpgalso fails with the same errors in the log file.Not sure how to debug this further. Tried enabling debug logs with ‘-loglevel debug’ but did not give me any extra info. Any help or suggestions

ffmpeg x11grab to streamable format
2 juin 2021, par Jintor2 FFMPEG process


(1) generating a ffmpeg x11grab to a .mp4
(2) take the .mp4 and restream it simultaneously to multiple rtmp endpoints


ISSUE the generated file in (1) have this error "moov atom not found"


This is the command that generate (1) :


ffmpeg -re -y -f x11grab -draw_mouse 0 -framerate 30 
-video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 
-movflags +faststart -preset ultrafast -crf 28 -refs 4 -qmin 4 
-pix_fmt yuv420p -filter:v fps=30 file.mp4


in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).


What I'm I missing


in (1)
-movflags +faststartdoesn't seem to fix the issue

••••••• EDIT : more details on the context ••••••


I'm using openvidu : webrtc with kurento and coturn.


The record feature creates a .mp4 on the fly as the chat is going on.


To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/


openvidu have also webhooks.


My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".


There is 2 options :


OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.


OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.


see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh


***************** EDIT 3 *************


in the .sh this is the part that is creating the mp4


ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"


How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...


**** EDIT 4 ********


I tried this it worked for 30 seconds and suddenly stopped
