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 (...) -

ffmpeg transcoding : Metallic distorsion on macOS
10 septembre 2024, par XaviI am following ffmpeg's transcoding.c example to record audio and video from my input devices into an mp4 output file with H264 and AAC as codecs. I have no issues with the video and the audio transcoding works correctly on Windows.


However, on macOS I have an issue with any input device other than the internal microphone of my laptop : the audio comes out distorted and sounding noisy and metallic (sample recording claps : https://file.io/nEn8MXHUAUQ2). I went through the input and output parameters for the filter several times, checked the values, but there must be something I'm missing. And I can't explain why it works on Windows with the same devices.


Has anyone run into a similar problem before ? Any idea where I should start looking at ?


Additional comments :


- 

- While the Macbook's internal microphone (the only one that works) has only one channel, the other microphones I have available are stereo, so I can't say for sure that that's where the problem is.
- I also tested it on a macbook mini, with the same results.
- ffmpeg 6.1.1, MacOs 14.5
- Input filter arguments :
time_base=1/1000000:sample_rate=48000:sample_fmt=1:channel_layout=stereo - Output filter arguments :
setpts=PTS-STARTPTS,aresample=48000:async=1:out_sample_fmt=8:out_chlayout=stereo,asetnsamples=n=1024

How can I use ffmpeg inside my wpf application
6 avril 2022, par KanotoI'm having some issue about using ffmpeg in my wpf project, I dunno why but it seems to not work inside msvc.




But it seems to work just fine in cmd.
I'm trying to use it in GoProControl project.
I already added path, $PATH with "C :\FFmpeg" and "C :\FFmpeg\bin" as well.
I have no idea why it doesn't work.
