Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

How to add custom configure option with VCPKG when building FFMPEG ?
1er novembre 2024, par NickWuzhDoes anyone know how to enable x11grab format in FFMPEG with VCPKG ?


I'm building FFMPEG in vcpkg manifest mode. Here is my vcpkg.json :


{
 "name": "project",
 "version": "1.0.0",
 "dependencies": [
 {
 "name": "ffmpeg",
 "features": [
 "avcodec",
 "avdevice",
 "avfilter",
 "avformat",
 "bzip2",
 "ffmpeg",
 "lzma",
 "postproc",
 "swresample",
 "swscale",
 "x264",
 "zlib"
 ]
 },
 "iniparser",
 "jsoncpp",
 "spdlog"
 ]
}




And I want to enable x11grab configuration in order to capture screen in Linux, but I found no feature was adapted.
Soon I found that —enable-libxcb was needed in configure and it was autodetect. So I build and install libxcb with source. And pkg-config can find it :


$ pkg-config --modversion xcb
1.17.0



But it doesn't work because in default it is —disable-autodetect in $VCPKG_ROOT/ports/ffmpeg/portfile.cmake :


set(OPTIONS "--enable-pic --disable-doc --enable-debug --enable-runtime-cpudetect --disable-autodetect")



I try to modify $VCPKG_ROOT/ports/ffmpeg/portfile.cmake —enalbe-autodetect, but it doesn't work either. Here is the short message when appling
vcpkg install --triplet x64-linux-release

ffmpeg use gpu to encode mpeg4 to ts/m3u8 [closed]
14 novembre 2024, par danielRICADOusing ffmpeg I want to trim and transcode a mpeg4 from ts / m3u8


std::string ffmpeg_command = "ffmpeg -hwaccel drm -i " + output_dir + input_file +
 " -ss 00:00:00.00 -t 31 -c:v " + codec + " -b:v " + std::to_string(bitrate) +
 " -vf scale=" + std::to_string(width) + "x" + std::to_string(height) +
 " -hls_time " + std::to_string(30) + " -hls_list_size 0 -hls_segment_filename " +
 ts_file_pattern + " -f hls " + m3u8_file;



I wanted to choose between codecs based on the system, if gpu is avaiable I'd like to opt to use it, right now I just check if the codec is available


bool is_h264_v4l2m2m_available() {
 std::string result = exec_command("ffmpeg -encoders 2>&1");
 return result.find("h264_v4l2m2m") != std::string::npos;
}



if it is a I wanted to move that process over to the gpu, not just use libx264. Here is the error log. Studying hard on the solution but wold super apperciate any expert advice.


other considerations are - runs in a docker container on a pi5, pibian on the host apline on in the container, container runs in privledged mode

How can use ffmpeg in AWS Lambda to clip hls trasnsimision to .mp4
15 novembre 2024, par Bruno MunnéThe ffmpeg input is through the public url of the bucket, I want to save the output in a tmp.mp4 file and I want to upload this file to the bucket. Locally the ffmpeg command works perfectly, lasting no more than 3 seconds and the output file weighs less than 1MB


export const handler = async (event) => {
 try {
 const { m3u8, offset, duration, signedURL } = event;

 const clipKey = `clip_output.mp4`;
 const clipFilePath = path.join('/tmp', clipKey);

 execSync(`/opt/ffmpeglib/ffmpeg -i ${process.env.URL_CLOUDFLARE}/${m3u8} -ss ${offset} -t ${duration} -c copy -f mp4 ${clipFilePath}`)

 const fileContent = fs.readFileSync(clipFilePath);
 const resSign = await fetch(signedURL, {
 method: "PUT",
 headers: {
 "Content-Type": "application/octet-stream",
 },
 body: fileContent,
 });

 if (!resSign.ok) throw new Error(`Failed to upload file to S3: ${resSign.statusText}`);

 fs.unlinkSync(clipFilePath);

 return {
 statusCode: 200,
 body: JSON.stringify({
 message: 'Clip procesado y subido correctamente',
 clipKey: path.basename(clipFilePath)
 }),
 };
 } catch (error) {
 console.error("Error al procesar el clip:", error);
 return {
 statusCode: 500,
 body: JSON.stringify({ error: error.message }),
 };
 }
};
