Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

How to make that video module can generate readable files for the module JW Player ?
4 janvier 2015, par DvexI use Drupal 7.x with Video Module, Video Pressets for FFMPEG and JW Player.
I install FFMPEG with this Guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu in Ubuntu 14.04I’m using jQuery 1.8
I downloaded the files that the JW Player module requires and renamed some files, as the guide tells me.
I set the video module so you can use FFMPEG and established the necessary pressets (FLV, MP4 and WebM) for any browser (web and mobile).
I changed the default settings of these pressets. I put check the option : Force one-pass Encoding. Because if not me error message :
PHPVideoToolkit error: Execute error. It was not possible to encode "/var/www/html/sites/default/files/private/videos/original/reel para web en loop_2.mp4" as FFmpeg returned an error. Note, however the error was encountered on the second pass of the encoding process and the first pass appear to go fine. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".

Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or heightWhen I save a node and add its corresponding video, the module generates the 3 files with their respective formats. But when thrown at the JW Player module, only plays FLV in every browser.
But not the MP4 or WebM.I checked the log and status report and all I get in order.
So I assume that the MP4 and WebM formats generated are not what the JW Player waiting.
Does anyone have the solution to this problem ? I tried to recompile FFMPEG with more codecs but it does not solve the problem.
This is my FFMPEG Configuration :

using libav instead of ffmpeg
21 janvier 2015, par n00bieI want to streaming video over http, i am using ogg(theora + vorbis), now i have sender and receiver, and i can run them using command line :
Sender :
ffmpeg -f video4linux2 -s 320x240 -i /dev/mycam -codec:v libtheora -qscale:v 5 -f ogg http://127.0.0.1:8080Receiver :
sudo gst-launch-0.10 tcpserversrc port = 8080 ! oggdemux ! theoradec ! autovideosinkNow, sender sends both audio and video, but receiver plays only video.
It works perfect, but now i want not to use ffmpeg and use only libav* instead.

}Here’s test example (i send video from webcam and dummy audio) :
class TestVVideoWriter : public sigslot::has_slots<>
{
public:
TestVVideoWriter( ) :
m_fileOpened( false )
{
}
void onCapturedFrame( cricket::VideoCapturer*, const cricket::CapturedFrame* capturedFrame )
{
if( m_fileOpened ) {
m_writer.writeVideoFrame( reinterpret_cast<const>( capturedFrame->data ),
capturedFrame->time_stamp / 1000 );
m_writer.writeAudioFrame( nullptr , 0 );
} else {
m_fileOpened = m_writer.openFile( "http://127.0.0.1:8080",
15, 40000, capturedFrame->width, capturedFrame->height,
16000, false, 64000 );
}
}
public:
vcore::VVideoWriter m_writer;
bool m_fileOpened;
};
TestVVideoWriter testWriter;

return;
}
}
}
}
}
std::cerr << "Problem has occured with camera" << std::endl;
}
BOOST_AUTO_TEST_SUITE_END() // TEST_VIDEO_WRITER
</const>But, in this case, gstreamer start playing video only when my test program stop executing (after 10 seconds in this case). It does not suit me, i want gstreamer start playing immediately after starting my test program.
Could someone help me ?
P.S. Sorry for my English.
