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 (...) -

Video stream played too fast if HTTP Live Stream starts at the beginning
22 avril 2013, par monkeymad2Bit of an odd problem this, I'm building a server that Transcodes video and streams it to the WiiU.
The WiiU seems to have quite good support of HTTP Live Streams, but I'm running into a problem where the video stream will play about x3 faster than intended (the audio plays at normal rate).
I'd figure something was up with my ffmpeg command, but if I let the stream run (so the first segment grabbed by the WiiU isn't actually the first segment) before I actually connect to it the WiiU will play the video at the normal rate !
Here's the ffmpeg command I've been using (post-shlex breakup) :
['./ffmpeg', '-threads', '4', '-i', '../../Torrents/Breaking.Bad.S05E02.720p.HDTV.x264-ORENJI.mkv', '-map', '0', '-codec:v', 'libx264', '-preset', 'superfast', '-codec:a', 'aac', '-ac', '2', '-crf', '23', '-flags', '-global_header', '-strict', 'experimental', '-f', 'segment', '-segment_list', 'playlist.m3u8', '-segment_list_flags', '+live', '-segment_time', '10', 'tmp/out%03d.ts']
And the first few lines of the .m3u8 :
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOWCACHE:1
#EXT-X-TARGETDURATION:10
#EXTINF:11.761756,
tmp/out000.ts
#EXTINF:8.591911,
tmp/out001.ts
#EXTINF:18.810467,
tmp/out002.ts
#EXTINF:7.841178,
...(PS, VLC + Safari can play the stream file.)
Any ideas what's happening ?
If it's a bug I have to work around rather than solve, any recommendations ?
Just tested starting the stream with a dummy.ts file (knowing it wont be read as the wiiu only reads the last 3 files in live mode) it still had the speedup, implying that it's something ffmpeg is putting in the first file (and only the first file...)

How to modify music pitch in audio of video file and still sound natural
9 janvier 2020, par Keith BennettI have some karaoke .mp4 video files (legally obtained) for Thai songs, and want to convert the pitch downward to fit my singing range. I’ve gotten most of the way there thanks to https://superuser.com/questions/292833/how-to-change-audio-frequency/1076762#1076762
using a command line like this :ffmpeg -i in.mp4 -af 'asetrate=35280.0,atempo=1.25' out.mp4
...but the instruments and human singing voices don’t sound natural at the modified pitch.
Is there a better way to change the pitch ? I know some commercial products can do this.
By the way, I wrote a Ruby script to simplify this ffmpeg call ; it’s at https://gist.github.com/keithrbennett/9ba7043792bfb2fcc92d615076a8413f. It enables you to specify a single factor, and modifies both pitch and tempo accordingly.
