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 (...) -

h264 : reset the private data in init_thread_copy()
29 mars 2015, par Anton Khirnovh264 : reset the private data in init_thread_copy()
The generic code copies the main context’s private data to all the
others. However that is quite dangerous, as it might end up copying some
pointers that are or will become invalid.Since everything we actually need will be copied later in
update_thread_context(), it’s safest to zero the private data in
init_thread_copy(), so it works the same way as init for the main
context. -
Concatenating videos using ffmpeg writes over empty audio stream
3 avril 2020, par Rutwik KharkarI have 4 movie files that I am trying to overlay and concatenate :



- 

- Intro file with an empty audio channel (generated using lavfi)
- Main movie file(s) that need to be concatenated and trimmed
- Watermark that needs to be overlaid on top of 2
- An outro movie that also has an empty channel.











Here is the command I am using to do all this :



ffmpeg -i temp_intro.mp4 -f concat -i tempFile.txt -i scoreboard.mp4 -i temp_outro.mp4 \
-filter_complex "[1]trim=end=24:start=12[s0];[s0]setpts=PTS-STARTPTS[s1];[1]atrim=end=24:start=12[s2];[s2]asetpts=PTS-STARTPTS[s3];\
[s1][s3]concat=a=1:n=1:v=1[s4];\
[2]format=yuva444p[s5];[s5]colorchannelmixer=aa=0.5[s6];\
[s4][s6]overlay=eof_action=repeat:x=(main_w-overlay_w)/2:y=main_h-overlay_h-20[s7];\
[0][s7][3]concat=n=3[s8]" test.mp4




Despite how ugly it looks, it mostly works - except for the audio. The audio starts playing as soon as the intro clip starts. I cannot create an output file with the overlaid movie because I also need to add fade-out and fade-in effects for the intro and outro. I can only re-encode once since I will be doing this over multiple large files every night.



Please suggest how I might be able to fix the audio issue.

Auto reconnect ffmpeg rtmpdump
24 juin 2014, par MarcI actually dump and restream live with rtmpdump and ffmpeg. Sometimes, the signal cut. I would like to know if it’s possible to make ffmpeg automatically restart the command when the signal cut.
Thanks
