La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

Video with drop frames with ffmpeg
28 mai 2018, par Gabe MataI am recording videos using ffmpeg in a production environment almost non-stop for 15 hours a day. Sometimes the videos are freezing for a few seconds.
I believe the hardware is adequate. It is an i7 with 16GB ram and windows 10. The videos are on average about 2:00 minute each.
This happens a few times a day 10 or so that I am awarded.
Here is a link to one of the videos that froze :
https://drive.google.com/open?id=1q6R2l1AkCko-uh2KZ6X8AChdGU5XBOy7
It freezes at 0:03 and then restarts at 0:16
Here is the ffmpeg command I am using :
ffmpeg -i "rtsp ://10.0.131.2/media/video1" -f segment -segment_time 9000 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c copy -map 0 gabe.mp4
Can I decreases the quality of the videos so videos don’t randomly freeze ?
Would recording without audio help the videos not randomly freeze ?
Thanks,
Gabe

Unable to create a PPAPI (Pepper) video plugin -NaCl module failed - how to resolve ?
27 novembre 2013, par ElHaixGoogle's Say Goodbye to Our Old Friend NPAPI blog post indicates that NPAPI plugin support will cease by the end of 2014 (in favor of PPAPI).
We have considered the option of using the ffmpeg libraries to create our own video plugin to simply decode RTSP encoded H.264 video streams on the client - important because we need as near real-time video display (avoiding transcoding latency). Using the ffmpeg libraries, there is still a 3-5 second delay in decoding the stream, not as fast as running MPlayer with the
-benchmark
option.In trying Google's PNaCl recommendation, we just got the LOADING status and the following error :
NativeClient : NaCl module load failed : PnaclCoordinator : Compile
process could not be created : ServiceRuntime : failed to startAre there any other alternatives or suggestions to getting this working ?

FFmpeg with libx264 skipped many frames during re-encoding
18 mai 2019, par IgorI found a strange problem with FFmpeg 4.1.3 when I re-encode this video file with libx264 and I use bitrate 8000k mode.
ffmpeg -y -i src.mp4 -c:v libx264 -preset slow -b:v 8000k dst.mp4
Source video (28 seconds) shows 3 images.
After re-encoding I see only 2 images and 3rd image is missing. I tested in latest VLC player 3.0.6, MPC-HC, Media player in Windows 10.
If I use crf video encoding instead of bitrate everything is fine.
