Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Create video file by mixing video and audio byte arrays FFmpeg & C++
20 janvier 2021, par Sergey ZinovevI capture audio and video.


Video is captured by using Desktop Duplication API and, as a result, I get Textures 2D.
These Textures 2D are char arrays.


m_immediateContext->CopyResource(currTexture, m_acquiredDesktopImage.Get());

D3D11_MAPPED_SUBRESOURCE* resource = new D3D11_MAPPED_SUBRESOURCE;
UINT subresource = D3D11CalcSubresource(0, 0, 0);

m_immediateContext->Map(currTexture, subresource, D3D11_MAP_READ_WRITE, 0, resource);

uchar * buffer = new uchar[(m_desc.Height * m_desc.Width * 4)];
const uchar * mappedData = static_cast<uchar>(resource->pData);
memcpy(buffer, mappedData, m_desc.Height * m_desc.Width * 4);
</uchar>

Then the Textures 2D convert in cv::Mat and write Video using OpenCV.


Audio captured by using WASAPI and, as a result, I get samples.


BYTE * buffer = new BYTE[(numFramesAvailable * pwfx->nBlockAlign)];
memcpy(buffer, pData, numFramesAvailable * pwfx->nBlockAlign);


These samples are byte arrays then write in WAV file.


As a result, I get two files - video and audio, which merged by using FFmpeg.


I want to skip the creation of video and audio files and promptly create one file compose of two strims (video and audio) from raw data.


In order to make it I need help with FFmpeg code.
Specifically, in a way of creating and setting the correct output context and output streams, and how to encode raw data.


I've already learned doc/examples FFmpeg, but still can't make the working code. So, I really need your help guys.

video previews on video just like xvideos
28 juin 2020, par zjoseVideo previews are usually images that rotate every so often in a small video. But since that format is old and boring, I would like to be able to create them with ffmpeg just like xvideos does.


example (you don't have to worry) -> https://img-l3.xvideos-cdn.com/videos/videopreview/dc/8b/0f/dc8b0facd2879bad18f93dff44d1de2c_169.mp4


They are in size : 362x204.
They last : 5 seconds.


and they are several fragments in video, and not in images.


How could I do it using ffmpeg ?

19 février 2021, par cantoeUse ffmpeg to add video watermark.
But the second video added does not move, only static images can be seen.
Does anyone know what's going on ?
Can you help me ?
