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 (...) -

MediaSPIP Player : problèmes potentiels
22 février 2011, parLe lecteur ne fonctionne pas sur Internet Explorer
Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

Single input variable for windows send to .bat
27 juillet 2015, par Tandy FreemanI want to get a framemd5 via ffmpeg by right clicking a file, selecting "send to", then selecting my.bat file.
Using this allows me to make framemd5s for every file in a directory :
for %%a in ("*.*") do C:\Users\bla\Downloads\avanti-092\Avanti-ffmpeg-GUI-092\ffmpeg\ffmpeg-20150513-git-51f6455-win64-static\ffmpeg-20150513-git-51f6455-win64-static\bin\ffmpeg.exe -i "%%a" -f framemd5 "%%~na.framemd5"pause
I want to just run the bat file on a single file, the one I right clicked on to begin with. I do not know which variable to use.

[dshow @ 047fea20] min ch=16 bits=16 rate= 48000 max ch=16 bits=16 rate= 48000This is the stream information for my current video/audio source, connected to the decklink card’s hdmi port
Stream #0:0: Video: rawvideo (UYVY / 0x59565955), uyvy422(tv), 1280x720, 59.94 tbr, 10000k tbn, 59.94 tbc
Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/sUltimately I will need to display this video on screen. And simultaneously be able to start and stop recording, while the preview keeps playing.
My idea was to use ffmpeg to capture the video and audio signal and transmit this to a network stream (eg 127.0.0.1:6666). Then use VLC player to display the stream (the preview). And ultimately start and/or stop another ffmpeg to save that same stream to disk.
In my mind this works, but I am no audio/video expert so if anyone with more experience could help out, I would appreciate it.
Update :
I have been able to display the video using ffplay, with the following command :
ffplay -f dshow -video_size 1280x720 -rtbufsize 702000k -framerate 60 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -threads 2
Next step is streaming it so I can view the stream (preview) with VLC.
Tried to use this command :
ffmpeg -f dshow -video_size 1280x720 -rtbufsize 702000k -framerate 60 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -threads 2 -f mpegts rtp://127.0.0.1:6666?pkt_size=188?buffer_size=65535
Which does not give any errors, so appears to work. But when I try to open the stream in VLC I get the following error :
SDP required :
A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (65).After a bit of reading it seems I should not be streaming to rtp :// but rather to udp ://
Command became :
ffmpeg -f dshow -video_size 1280x720 -rtbufsize 702000k -framerate 60 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -threads 2 -f mpegts udp://127.0.0.1:6666?pkt_size=188?buffer_size=65535
And when I try to open it now in VLC I get no error, no warning, but also no video.
Time for some more reading.
