Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

How to convert Lagarith .avi videos to MP4 using WinFF
24 avril 2014, par MoeinI have a bunch of .avi videos encoded with Lagarith codec. We would like to convert them in to a lossless .MP4 format so that they could be easily played on html. I want to keep video specifications remain the same if it’s possible and just convert the video to MP4.
I tried WinFF and also some manually written FFmpeg codes [without any specific reference to the Lagarith codec] but they all create a video which is not playable (neither with Windows Player nor with the HTML5 player). Also, FFmpeg returns exceptions like bellow.
Edit :
Here is the FFmpeg code generated by WinFF, this code gives me the following Exception :"C:\Program Files\WinFF\ffmpeg.exe" -y -i "C:\Desktop\Videos\input.avi" -f mp4 -r 29.97 -vcodec libx264 -preset slow -vf scale=640:480 -b:v 1000k -aspect 4:3 -flags +loop -cmp chroma -b:v 1250k -maxrate 1500k -bufsize 4M -bt 256k -refs 1 -bf 3 -coder 1 -me_method umh -me_range 16 -subq 7 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec libvo_aacenc -b:a 112k -ar 48000 -ac 2 "C:\Desktop\Videos\output.mp4"

How to record frames with ffmpeg and finish the recording
20 février 2024, par Jorge Augusto WilchenIn the following code, i trying to create a class to record frames from an IP camera (RTSP), save frames on a .avi file and finish the record, but, when i kill the operation, the video file may be corrupted. Have any other more safely way to stop the ffmpeg recording ?


.cpp file :


#include "videorecorder.h"


VideoRecorder::VideoRecorder(const std::string& rtspUrl) :
 url(rtspUrl),
 recording(false)
{

}

VideoRecorder::~VideoRecorder()
{
 end_record();

{
 if (recording) {
 std::cerr << "Already recording." << std::endl;
 return false;
 }

 std::string command = "ffmpeg -rtsp_transport udp -i " + url
 + " -c:v mjpeg -preset fast -qp 0 " + fileName;

 videoWriter = popen(command.c_str(), "w");
 if (!videoWriter) {
 std::cerr << "Error opening ffmpeg process." << std::endl;
 return false;
 }

 recording = true;
 ffmpegProcessId = getpid();
 std::cout << "Recording started." << std::endl;
 return true;
}

bool VideoRecorder::end_record()
{
 if (recording) {
 if (videoWriter) {
 pid_t ffmpegPID = fileno(videoWriter);

 if (kill(ffmpegPID, SIGTERM) == 0) {
 std::cout << "Recording terminated successfully." << std::endl;
 } else {
 std::cerr << "Error terminating recording." << std::endl;
 return false;
 }

 int status = pclose(videoWriter);

 if (status == 0) {
 std::cout << "Recording ended successfully." << std::endl;
 } else {
 std::cerr << "Error ending recording. pclose status: " << status << std::endl;
 return false;
 }
 } else {
 std::cerr << "Error ending recording. videoWriter is nullptr." << std::endl;
 return false;
 }

 recording = false;
 return true;
 }

 return false;
}

I'm using the ffmpeg lib becouse i need max speed on frames recording, and OpenCV and AV Lib is much slowness than ffmpeg.


This my terminal output after recording during 10 seconds (generated a file with 23 seconds duration) :

FFmpeg RTSP drop rate increases when frame rate is reduced
13 avril 2024, par Avishka PereraI need to read an RTSP stream, process the images individually in Python, and then write the images back to an RTSP stream. As the RTSP server, I am using Mediamtx [1]. For streaming, I am using FFmpeg [2].


I have the following code that works perfectly fine. For simplification purposes, I am streaming three generated images.


import time
import numpy as np
import subprocess

width, height = 640, 480
fps = 25
rtsp_server_address = f"rtsp://localhost:8554/mystream"

ffmpeg_cmd = [
 "ffmpeg",
 "-re",
 "-f",
 "rawvideo",
 "-pix_fmt",
 "rgb24",
 "-s",
 f"{width}x{height}",
 "-i",
 "-",
 "-r",
 str(fps),
 "-avoid_negative_ts",
 "make_zero",
 "-vcodec",
 "libx264",
 "-threads",
 "4",
 "-f",
 "rtsp",
 rtsp_server_address,
]
colors = np.array(
 [
 [255, 0, 0],
 [0, 255, 0],
 [0, 0, 255],
 ]
).reshape(3, 1, 1, 3)
images = (np.ones((3, width, height, 3)) * colors).astype(np.uint8)

if __name__ == "__main__":

 process = subprocess.Popen(ffmpeg_cmd, stdin=subprocess.PIPE)
 start = time.time()
 exported = 0
 while True:
 exported += 1
 next_time = start + exported / fps
 now = time.time()
 if next_time > now:
 sleep_dur = next_time - now
 time.sleep(sleep_dur)

 image = images[exported % 3]
 image_bytes = image.tobytes()

 process.stdin.write(image_bytes)
 process.stdin.flush()

 process.stdin.close()
 process.wait()


The issue is, that I need to run this at 10 fps because the processing step is heavy and can only afford 10 fps. Hence, as I reduce the frame rate from 25 to 10, the drop rate increases from 0% to 100%. And after a few iterations, I get a
BrokenPipeError: [Errno 32] Broken pipe. Refer to the appendix for the complete log.

As an alternative, I can use OpenCV compiled from source with GStreamer [3], but I prefer using FFmpeg to make the shipping process simple. Since compiling OpenCV from source can be tedious and dependent on the system.

Creating the source stream


To instantiate the unprocessed stream, I use the following command. This streams the content of my webcam as and RTSP stream.


ffmpeg -video_size 1280x720 -i /dev/video0 -avoid_negative_ts make_zero -vcodec libx264 -r 10 -f rtsp rtsp://localhost:8554/webcam
