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. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

Streaming live video from Windows to Android with FFmpeg
29 avril 2018, par Alan DanielsI am capturing live video on a Windows PC and encoding it with FFmpeg. I can stream the content live to another PC using
rtsp://[dest_ip:port]/live.sdp
as FFmpeg’s output on the sender and usingffplay -rtsp_flags listen rtsp://[dest_ip:port]/live.sdp
on the receiver. However, I have to run FFplay before starting the sender. Also, VLC cannot play the rtsp path :main debug: net: connecting to 127.0.0.1 port 5555
main error: connection failed: Connection refused by peer
access_realrtsp error: cannot connect to 127.0.0.1:5555
access_realrtsp debug: could not connect to: 127.0.0.1:5555/live.sdpHowever, FFplay and VLC can play something like
ffplay rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov
.On the Android side, I am using the Media API which can play content from a URI. It works with HTTP and RTSP (as far as I know).
I’ve looked at FFmpeg’s streaming guide : https://trac.ffmpeg.org/wiki/StreamingGuide, but I am still confused about the difference between my path
rtsp://[dest_ip:port]/live.sdp
andrtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov
.Do I need a streaming server in order to have my content accessible by URI ? Any recommendations since FFserver is depreciated ?

Avconv : Select german stream not highest quality one
6 novembre 2017, par mblaettermannI am converting some input stream from my DVB S2 Card to RTMP.
Everything works fine after switching to recent avconv and x264 :)
The only thing I couldn’t find out is, how do I select the right audio stream ?
The source sometimes has up to 6 audio tracks. Avconv automatically chooses the one with the highest bitrate. However I want to select the "ger" one :
Here are the streams of ARTE german/french TV Channel for example :
Input #0, mpegts, from 'http://192.168.1.50:9981/stream/channelid/1035':
Duration: N/A, start: 19083.694722, bitrate: 15576 kb/s
Program 1
Stream #0.0[0xa8], 127, 1/90000: Video: mpeg2video (Main), yuv420p, 544x576 [PAR 32:17 DAR 16:9], 1/50, 15000 kb/s, 25 fps, 90k tb50 tbc
Stream #0.1[0x70](fre), 204, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 192 kb/s
Stream #0.2[0x71](ger), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
Stream #0.3[0x72](eng), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
Stream #0.4[0x73](qaa), 207, 1/90000: Audio: mp2, 48000 Hz, stereo, s16p, 128 kb/s
No Program
Stream #0.5[0x3b], 126, 1/90000: Audio: mp1, 0 channels, s16plibav Docs are really not that helpful. Who does now the right syntax ?
EDIT : I found the -map option : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20use%20-map%20option But it is not possible to map by name ? Only by index ?
Maybe I need to use avprobe then, to find the corrent stream index for "ger".
