Amélioration de la version de base
13 septembre 2013Jolie sélection multiple
Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...) -

Is it possible to embed ffplay ?
18 mars, par EthanLffmpeg's viewer, ffplay, has a lot of great options for optimizing viewing experience. I've been able to get it to nicely display an RTSP stream at low latency. However, it's been difficult to include it in a GUI.


Is that possible ? Is there a GUI that does that ?


Note : I am NOT trying to embed in a browser, or just toss the window on top of a GUI.


Best solution : desktop GUI that includes ffplay in a widget


First alternative : desktop GUI that has variable opacity. If the ffplay window is layered below the GUI, and the GUI is transparent, it could look decent. However, some buttons would have to be visible, so the entire window can't be transparent.


Second alternative : disable the possibility of user interaction with the ffplay window. Then, the ffplay window could just be tossed to the side of the screen, and it would remain there as a split screen, without concern that a user could minimize it or move it.

Enhance text image in x264encoding
23 août 2016, par useprxfI’m making use of x264 for remote desktop streaming. The goal is to achieve both low bitrate and high video quality within the computation budget. The current parameter set I used almost achieve this goal, but it fails in handling images with many texts (e.g. browsing websites schene). The text in image is blurred and affects the user experience.
I think it’s the quantization in x264 that causes this. The quantization after DCT transform will eliminate high frequency sinals which mainly correspond to texts in image.
So, my question is how to do improve the text quality in x264 encoding ?
My idea : when the bitrate stays at a low level for a period of time,
- set
crf
to be 0 (lossless) ; - encode current frame as an IDR frame and then send it ;
- recover the
crf
.
Also, a flag should be used to prevent resending when bitrate keeps low for a long time. I haven’t try this method since I don’t know how to mark a frame as an IDR frame manully and then encode it.

Custom container in FFmpeg's libavformat
16 novembre 2016, par Tiago TomásI have a media server in Java capable of reading from multiple audio/video containers, encoding and also delivery using a different set of containers. For this, I’m using FFmpeg by launching multiple processes from Java.
I’ve been tasked with implementing audio/video delivery using a custom (proprietary) container format that supports multiple audio/video codecs in order to integrate with another video delivery system.
I’m currently evaluating my options and I’ve reached the conclusion that I either :
- Export audio/video from FFmpeg using an easily parseable format and then simply convert into the proprietary format, or
- I modify libavformat itself in order to add the new container format
I’m strongly inclined to try the second approach but I’m pressed for time and as such, I would like to ask whether anyone has had experience with custom container formats and can provide me with some guidance.
If not, a recommendation on which container to use (that can be easily parsed) for the first approach would also be really helpful.
Thank you in advance.
