  • 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 :-)
