Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

Concatenating videos Audio/Video out of sync : Non-monotonous TDS output
6 août 2020, par inviderI am trying to add two videos using ffmpeg and the output video/audio is out of sync (and fast forwarded). Goal is to put
intro.mp4
before the original fileclip.flv



My approach is to



- 

- Change the format of
clip.flv
toclip.mp4





ffmpeg -i clip.flv -q 0 -c copy clip.mp4




- 

- Concat
intro.mp4
withclip.mp4





ffmpeg -f concat -safe 0 -i filesToJoin.txt -c copy combinedvideo.mp4




I see this in output log for command#2



[mp4 @ 0x3ebcd60] Non-monotonous DTS in output stream 0:0; previous: 392311, current: 391925; changing to 392312. This may result in incorrect timestamps in the output file.

Things I have tried



- 

- As you'll see that the both videos have same frame rate but different timescale, I have tried changing the timescale of one of the video to match the other before combining the video but with no luck. For timescale change I used this command





ffmpeg -i clip.mp4 -video_track_timescale 30000 clip_ts30000.mp4

- I have seen the similar questions on SO, no luck

FFmpeg freezes on the same frame and gets stuck on it
12 juin 2020, par rilesI'm trying to figure out why the following ffmpeg (4.2.1) command, which works well most of the time, sometimes ends up stuck on the same frame.



This ffmpeg command allows me to make a LIVE streaming with recording VOD at the same time.



Has anyone ever had this problem ?



Thank you in advance for your help.
