VDR Portal

Quoted from "Maniac"

Ich hatte bis jetzt noch keine Möglichkeit das zu testen, aber verbessert sich das Schnittmarken-Problem dadurch?
Wenn ich den Code richtig in Erinnerung habe, wird beim StillPicture der PTS auf 0 gesetzt.

Interesting... Anyway, this code path is used only with vdr-1.6.0 (PES)
recordings. Similar hack for vdr-1.7.x recordings would need to go to
demux_xvdr.c. You need to add following line to function check_newpts():

if (video) {
int still_mode = (int)this->stream->metronom->get_option(this->stream->metronom, XVDR_METRONOM_STILL_MODE);
int trick_speed = (int)this->stream->metronom->get_option(this->stream->metronom, XVDR_METRONOM_TRICK_SPEED);
if (still_mode > 0 || trick_speed > 0) {
LOGMSG("Skipping new pts %"PRId64" (still=%d trickspeed=%d)", buf->pts, still_mode, trick_speed);
+ if (still_mode) buf->pts = 9000;
return;
}
}

Currently video frame PTS timestamp is not cleared, but it is also not
used to generate xine vpts. Maybe vdpau uses the original pts timestamp
for something ... ? That would cause problems.

What vdr version are you using ?
Moving cutting marks (still images) work perfectly well with software
decoders, so there must be something weird with timestamps. If you use
--verbose option, do you see any "frame dropped, too old..." or
"Skipping new pts"... etc. messages when moving cutting marks ?

Es gibt wieder Nachschub an der xine-lib Front...

hast Du da einen guten Durchblick? welche Branch sollte man nun nehmen? ...

Das sind 2 wirklich sehr gute Fragen, ich habe den Überblick schon lange verloren.....
