Audio HLS with metadata on Mac from directory of mp3 files ?
2 février 2017, par eagspooI’m trying to create HLS output (m3u8 file + many .ts files) from a list of mp3 files where the mp3 id3 metadata is preserved in the HLS output.
I’ve been trying ffmpeg like this :
ffmpeg -f concat -i list.txt -hls_init_time 2 -hls_time 2 out.m3u8
where list.txt contains :
file 01.mp3
file 02.mp3
file 03.mp3
file 04.mp3
file 05.mp3
file 06.mp3
file 07.mp3
file 08.mp3
file 09.mp3
file 10.mp3The result is a single out.m3u8 file and a single very large out0.ts file. I was expecting about 1500 ts files and an m3u8 file that contains the last 5 ts files.
I’m completely new to ffmpeg and honestly I don’t want to learn it in depth right now.
Does anyone know how to do this either with ffmpeg or otherwise ?

[hls @ 0x7fc50f01aa00] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or -vsync 2
No pixel format specified, yuvj444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.

Using AFORGE to record the videos in c#
11 octobre 2015, par Muhammad Naumani’ve try the following way to record the video from the Webcam by 25 Frame-rate per sec for 10sec but when i get the out put video it is of 2sec and the frames are played to fast as compare to the video stream.
The code is as follows.
using System;
using System.Drawing;
using System.Windows.Forms;
using AForge.Video;
using AForge.Video.DirectShow;
using System.Threading;
using AForge.Video.FFMPEG;
namespace AforgeTutorial
{
public partial class Form1 : Form
{
private FilterInfoCollection ListOfCams;
private VideoCaptureDevice SelectedCam; //From where we will take image
System.Timers.Timer tim;
Thread t;
bool isNewFrame = false;
VideoFileWriter writer;
public Form1()
{
InitializeComponent();
tim = new System.Timers.Timer(10000);
tim.Elapsed += new System.Timers.ElapsedEventHandler(tim_Elapsed);
t = new Thread(saveVideo);
}
void tim_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
if (isRecord)
{
writer.Close();
isRecord = false;
}
}
private void Form1_Load(object sender, EventArgs e)
{
ListOfCams = new FilterInfoCollection(FilterCategory.VideoInputDevice);
if (ListOfCams.Count == 0)
return;
comboBox1.Items.Clear();
foreach (FilterInfo Cam in ListOfCams)
{
comboBox1.Items.Add(Cam.Name);
}
}
private void StopCamera()
{
SelectedCam.SignalToStop();
SelectedCam.Stop();
}
bool isRecord = false;
private void Start_Click(object sender, EventArgs e)
{
if (comboBox1.Text == string.Empty)
return;
SelectedCam = new VideoCaptureDevice(ListOfCams[comboBox1.SelectedIndex].MonikerString);
SelectedCam.NewFrame += new NewFrameEventHandler(SelectedCam_NewFrame);
SelectedCam.Start();
}
Bitmap image;
void SelectedCam_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
image = (Bitmap)eventArgs.Frame.Clone();
isNewFrame = true;
pictureBox1.Image = (Bitmap)eventArgs.Frame.Clone();
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
StopCamera();
}
private void Stop_Click(object sender, EventArgs e)
{
StopCamera();
}
private void btnRecord_Click(object sender, EventArgs e)
{
tim.Start();
if (!isRecord)
{
writer = new VideoFileWriter();
writer.Open(@"C:/code-bude_test_video.mp4", 640, 480, 25, VideoCodec.MPEG4,10000);
}
isRecord = !isRecord;
if (isRecord)
t.Start();
}
void saveVideo()
{
while (isRecord)
{
if (isNewFrame)
{
writer.WriteVideoFrame(image);
isNewFrame = false;
}
}
}
}
