Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement.

Still getting FFMPEG "Segmentation fault" with network stream source with the AmazonLinux 2023 distro [closed]
28 décembre 2023, par Matthew DrookerAfter referencing https://docs.yucca.app/en/troubleshooting/Segmentation_fault_core_dumped


And using


FFMPEG "Segmentation fault" with network stream source


I thought I had this solved.
But still having the same issue as documented as fixed.


Im using AmazonLinux 2023 distro in a Lambda custom image.


Im trying to use baseImage from
FROM --platform=linux/amd64 public.ecr.aws/lambda/nodejs:20


Then doing-
RUN dnf install nscd -y
in my Dockerfile allowing the nscd service to be installed per the answer.

But, Im still getting the
ffprobe was killed with signal SIGSEGV
error with the new AmazonLinux Distro.

Has anyone else faced this with the 2023 Distro ? Or have an answer to this question ?

Combining two multi-channel streams into one
31 mars 2023, par Christiaan RoselaarHi to all you FFmpeg Guru's.


I'm doing my best to combine two incoming webstreams on my server. One of them containing two (2) mono audio-channels, the other five (5). The objective is to create one stream containing seven (7) channels, to be routed directly to the hardware.


At the two transmission-origins, host_a and host_b, the streams are generated as follows :


host_a : $ ffmpeg -hide_banner -loglevel error -f jack -channels 1 -i Tonmeister_mic1 -f jack -channels 1 -i Tonmeister_mic2 -nostdin -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map "[a]" -codec:a libopus -b:a 128k -vbr on -packet_loss 10 -fec on -compression_level 10 -frame_duration 20 -application audio -f mpegts udp ://X.X.X.X:yyyy &


host_b : $ ffmpeg -hide_banner -loglevel error -f jack -channels 1 -i Tonmeister_mic1 -f jack -channels 1 -i Tonmeister_mic2 -f jack -channels 1 -i Tonmeister_mic3 -f jack -channels 1 -i Tonmeister_mic4 -f jack -channels 1 -i Tonmeister_mic5 -nostdin -filter_complex "[0:a][1:a][2:a][3:a][4:a]amerge=inputs=5[a]" -map "[a]" -codec:a libopus -b:a 128k -vbr on -packet_loss 10 -fec on -compression_level 10 -frame_duration 20 -application audio -f mpegts udp ://X.X.X.X:zzzz &


The streams do seem to get in allright :


cjr-macbook : CJR$ ffprobe -hide_banner -i udp ://127.0.0.1:yyyy
Input #0, mpegts, from 'udp ://127.0.0.1:yyyy' :
Duration : N/A, start : 4759.783900, bitrate : N/A

cjr-macbook : CJR$ ffprobe -hide_banner -i udp ://127.0.0.1:zzzz

Stream #0:0[0x100] : Audio : opus (Opus / 0x7375704F), 48000 Hz, 5.0, fltp


However, I just cannot figure out how to combine the seven (7) channels present in these two incoming streams into one seven-channel stream.


At the receiving end I tried various commands, amongst others


cjr-macbook : CJR$ ffmpeg -hide_banner -loglevel verbose -i udp ://127.0.0.1:yyyy -i udp ://127.0.0.1:zzzz -filter_complex "[0:a]channelsplit=channel_layout=stereo[b]" ;"[1:a]channelsplit=channel_layout=5.0[c]" ;"[b][c]amerge=inputs=7[d]" -map "[d]" sevenchannels.wav


Any help appreciated !
