  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • rtp mpg stream using jrtplib occurred error "illegal timestamp unit"

    13 avril 2013, par socket

    I wanna code rtp video stream sender and use VLC to play it in the LAN. I just have a mpeg4 file "a.mpg". And in my opinion, jrtplib can pack the packed well, so I think I can use sendPacket() function directly to send the mpg file. code below :

    #include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include 
    
#include <iostream>
    
#include
    

    
using namespace jrtplib;
    
using namespace std;
    
int main()
    
{
    
RTPSession s;
    
RTPSessionParams sparam;
    
s.SetTimestampUnit(160.0/104857.0);//~
    
RTPUDPv4TransmissionParams tparam;
    
tparam.SetPortbase(9000);
    
int status=s.Create(sparam,&amp;tparam);
    
if(status&lt;0)
    
{
    
    cerr&lt;&lt;"error 1"&lt;/~
    
s.SetDefaultMark(false);
    
s.SetDefaultTimestampIncrement(160);//~~
    

    
unsigned char buf[160];
    
FILE*f=fopen("a.mpg","rb");
    
while(!feof(f))
    
{
    
    fread(buf,1,160,f);
    
    RTPTime delay(0.02);//~
    
    bool ret=false;
    
    status=s.SendPacket(buf,160);
    
    if(status&lt;0)
    
    {
    
        cerr&lt;&lt;"error 3"&lt;code></iostream>

    Then, I compile it :

     g++ jrtpsend.cpp -ljrtp -I /usr/local/include/jrtplib3

    After that, I run the program but error occurred :

    kl@kl-ubuntu:~/code/RTP$ ./a.out 
    
error 1
    
Speficied an illegal timestamp unit for the the RTCP packet builder

    Actually, I didn't know timestamp exactly. When I use ffplay to play a.mpg showing that :

    Input #0, mpeg, from &#39;a.mpg&#39;:q=    0KB vq=    0KB sq=    0B f=0/0   
    
Duration: 00:01:00.69, start: 0.529089, bitrate: 556 kb/s
    
Stream #0:0[0x1e0]: Video: mpeg1video, yuv420p, 640x480 [SAR 239:182 DAR 478:273],   104857 kb/s, 25 fps, 25 tbr, 90k tbn, 25 tbc
    
Stream #0:1[0x1c0]: Audio: mp2, 44100 Hz, stereo, s16p, 128 kb/s

    2.46 A-V : -0.003 fd= 7 aq= 2KB vq= 33KB sq= 0B f=0/0

    So, I use the data 104857kb/s in the code (setTimestampUnit()), but I have no idea whether I use it correctly.
    All in all, please give me some suggestion how to run the program well or ...
    Best regards :-)
