Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

AForge.Video.FFMPEG used in C#
30 décembre 2018, par cuong nguyenI use Visual C# 2008 and want to write AVI file from bmp sequences.
I found AForge.Video.VWF but it’s just for "vmw3" or "DIB " codecs and I want to use AForge.Video.FFMPEG but it got error.
For example I just code :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using AForge.Video.FFMPEG;
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
VideoFileWriter vfw = new VideoFileWriter();
}
}
}But I got this
filenotfoundexception{"The specified module could not be found. (Exception from HRESULT: 0x8007007E)":null} -
ffmpeg and pulse audio creating buzzy speech
17 juin 2017, par flashapeI’m attempting to record video and audio from an ec2 instance (Ubuntu 16.04), using xvfb and pulse audio. Everything works fine, except that the output file contains "buzzy" speech (not sure if this is what "clipping" is ?). This happens using either aac or mp3 audio codecs.
Sample audio file : http://s000.tinyupload.com/index.php?file_id=86237391396073526211
ffmpeg command :
ffmpeg \
-f x11grab -framerate 30 -video_size ${SCREEN_WIDTH}x${SCREEN_HEIGHT} -i :1.0 \
-f pulse -i default \
-c:v libx264 -preset veryfast -maxrate 2500k -bufsize 2500k -vf "format=yuv420p" -g 60 \
-c:a aac -strict -2 -channel_layout stereo -ab 256k -ar 48000 -bufsize 512k -ac 2 \
-flags +global_header -f flv "test.mp4"The output from ffmpeg when I run the command :

Stream mapping:
Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
Stream #1:0 -> #0:1 (pcm_s16le (native) -> aac (native))Based on various posts, I thought it might be something in the pulse config, particularly the "resample-method" setting, but that doesn’t appear to do anything. Here is how the /etc/pulse/daemon.conf config file currently stands :

Ok, updated the ffmpeg command to capture only the audio, but still have the same issue :
ffmpeg \
-f pulse -i default \
-c:a aac -strict -2 -channel_layout stereo -ab 256k -ar 48000 -bufsize 512k -ac 2 \
test.aacI do get some interesting messages in the output about timestamps being off :

Opencv crosscompile with ffmpeg and other 3rdparty for arm board
16 juin 2017, par Little ToothAfter buliding Qt5.5.1 for my arm board sucessfully, I am taking up to crosscompile opencv. Here are the steps :
First, I crosscompile 3rdparty :

/home/newdisk/optnew/opencv-rely/includeWhy can cmake find lib directory
-- Found ZLIB: /home/newdisk/optnew/opencv-rely/lib/libz.so (found suitable version "1.2.8", minimum required is "1.2.3")but cannot find include directory ?
/home/newdisk/optnew/opencv-rely/includeDo you have any idea ?
