[linux-dvb] Problems with getting and demuxing TS

[Markku Leinio <markkunyys@dc.turkuamk.fi>]

I took the test_dvr.c source from DVB CVS and tried to simplify it to be 
able to get TS from our DVB-S card. But now ts_demux is not working 
anymore. ts2pes works if used with a file, but with live input (got from 
tsget.c below) it doesn't output all the stream, only something.

With previous DVB 0.8.2 and /dev/video we were able to get TS and also were 
able to ts_demux it straight. The newly compiled (0.9) ts_demux can demux 
our old TS files but not the new ones. Is there something wrong with this 
quick-and-dirty code and its output? I only want to get some transport 
stream and be able to ts_demux it (and maybe something else). I would 
appreciate a simple solution...


/* tsget.c */

#include <sys/ioctl.h>
#include <stdio.h>
#include <stdint.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

#include <ost/dmx.h>
#include <ost/video.h>

main()
{
   int len;
   struct dmxPesFilterParams pesFilterParams;
   uint8_t buf[4096];

   int fd_dvr;
   int fd_demux;
   int fd_demux2;

   fd_dvr=open("/dev/ost/dvr", O_RDONLY);
   fd_demux=open("/dev/ost/demux", O_RDWR|O_NONBLOCK);
   fd_demux2=open("/dev/ost/demux", O_RDWR|O_NONBLOCK);

   pesFilterParams.pid = 0xa2;
   pesFilterParams.input = DMX_IN_FRONTEND;
   pesFilterParams.output = DMX_OUT_TS_TAP;
   pesFilterParams.pesType = DMX_PES_VIDEO;
   pesFilterParams.flags = DMX_IMMEDIATE_START;
   if (ioctl(fd_demux, DMX_SET_PES_FILTER, &pesFilterParams) < 0){
     perror("crap");
     return(1);
   }

   pesFilterParams.pid = 0x60;
   pesFilterParams.input = DMX_IN_FRONTEND;
   pesFilterParams.output = DMX_OUT_TS_TAP;
   pesFilterParams.pesType = DMX_PES_AUDIO;
   pesFilterParams.flags = DMX_IMMEDIATE_START;
   if (ioctl(fd_demux2, DMX_SET_PES_FILTER, &pesFilterParams) < 
0)   return(1);

   while (1) {
     len=read(fd_dvr, buf, 4096);
     if (len>0) write (1, buf, len); /* writes to STDOUT */
   }
}
