[linux-dvb] AW: Re: cutting problems with VDR 0.80

[Richard Reuters <Richard.Reuters@web.de>]

Klaus,

I have problems with cutting, too. The log shows the following entries:

Jun 10 12:00:09 l0100001 vdr-mp3[2400]: video cutting thread started
(pid=2400)
Jun 10 12:00:09 l0100001 vdr-mp3[914]: info: Schnitt gestartet

Jun 10 12:00:57 l0100001 vdr-mp3[2400]: end video cutting thread

This is vdr 0.8 (with an mp3 extension) and a current dvb driver. I use 2
"old" DVB-S cards.

Line 1196 points to

void cCuttingBuffer::Action(void)
{
  [...]
              if (fromFile >= 0) {
                 if (Length <= (int)sizeof(buffer)) {
                    if (read(fromFile, buffer, Length) < 0) {
===>                   LOG_ERROR;
                       break;
                       }
                    }

Another error while recording:

Line 535 points to

void cRecordBuffer::Input(void)
{
  dsyslog(LOG_INFO, "input thread started (pid=%d)", getpid());

  uchar b[MINVIDEODATA];
  time_t t = time(NULL);
  recording = true;
  for (;;) {
      int r = read(videoDev, b, sizeof(b));
      if (r > 0) {
         uchar *p = b;
         while (r > 0) {
               int w = Put(p, r);
               p += w;
               r -= w;
               }
         t = time(NULL);
         }
      else if (r < 0) {
         if (errno != EAGAIN) {
===>        LOG_ERROR;
            if (errno != EBUFFEROVERFLOW)
               break;
            }
         }

Recording is very unreliable, resulting in zero-bytes files. When recording
with the 2nd dvb card, only 10 percent of the recordings are successful.
When recording to the 1st dvb card the results are somewhat better.

I have just now received this message from the list (maybe some problem
with the list server?). I haven't had time to look into this problem yet,
but I guess it must be somewhere in dvbapi.c, cCuttingBuffer::Action().
