How to get a notification of a completed transponder scan?
by Luca Olivetti 30 Mar '05

30 Mar '05

Currently both the channelscan and the actuator plugin offer an option to scan a complete satellite by tuning to each transponder and then waiting for 10 seconds. Is it possible to get a notification when all of the transponder data has been received? (I's assume it'd take less than 10 seconds, so a complete satellite scan should be noticeably faster).

vdr-xine: is this code thread safe?
by Reinhard Nissl 30 Mar '05

30 Mar '05

Hi, while facing deadlocks in xine I've written an emulation of an recursive mutex, as xine cannot use non posix extensions to be portable. The code below seems to work but are there any errors left? What happens if the thread owning the lock is cancelled? Feel free to send me your improvements. Thanks! /* * xine_rmutex - xine's recursive mutex emulation */ struct xine_rmutex_s { pthread_mutex_t access_rmutex; pthread_cond_t unlock_cond; int lock_count; pthread_t lock_owner; }; typedef struct xine_rmutex_s xine_rmutex_t; int _x_rmutex_init(xine_rmutex_t *rmutex); int _x_rmutex_lock(xine_rmutex_t *rmutex); int _x_rmutex_timedlock(xine_rmutex_t *rmutex, int ms_to_time_out); int _x_rmutex_unlock(xine_rmutex_t *rmutex); int _x_rmutex_destroy(xine_rmutex_t *rmutex); #include "assert.h" int _x_rmutex_init(xine_rmutex_t *rmutex) { pthread_mutex_init(&rmutex->access_rmutex, 0); pthread_cond_init(&rmutex->unlock_cond, 0); rmutex->lock_count = 0; return 0; } int _x_rmutex_lock(xine_rmutex_t *rmutex) { return _x_rmutex_timedlock(rmutex, -1); } int _x_rmutex_timedlock(xine_rmutex_t *rmutex, int ms_to_time_out) { int r = 0; struct timespec abstime; { struct timeval now; gettimeofday(&now, 0); abstime.tv_sec = now.tv_sec + ms_to_time_out / 1000; abstime.tv_nsec = now.tv_usec * 1000 + (ms_to_time_out % 1000) * 1e6; if (abstime.tv_nsec > 1e9) { abstime.tv_nsec -= 1e9; abstime.tv_sec++; } } pthread_mutex_lock(&rmutex->access_rmutex); assert(rmutex->lock_count >= 0); while (0 == r && rmutex->lock_count > 0 && !pthread_equal(rmutex->lock_owner, pthread_self())) { if (ms_to_time_out < 0) pthread_cond_wait(&rmutex->unlock_cond, &rmutex->access_rmutex); else r = pthread_cond_timedwait(&rmutex->unlock_cond, &rmutex->access_rmutex, &abstime); } if (0 == r) { rmutex->lock_owner = pthread_self(); rmutex->lock_count++; } pthread_mutex_unlock(&rmutex->access_rmutex); return r; } int _x_rmutex_unlock(xine_rmutex_t *rmutex) { int r = 0; pthread_mutex_lock(&rmutex->access_rmutex); assert(rmutex->lock_count > 0); assert(pthread_equal(rmutex->lock_owner, pthread_self())); rmutex->lock_count--; if (rmutex->lock_count == 0) pthread_cond_broadcast(&rmutex->unlock_cond); pthread_mutex_unlock(&rmutex->access_rmutex); return r; } int _x_rmutex_destroy(xine_rmutex_t *rmutex) { pthread_cond_destroy(&rmutex->unlock_cond); pthread_mutex_destroy(&rmutex->access_rmutex); return 0; } Bye. -- Dipl.-Inform.

[ANNOUNCE] vdr-osdteletext-0.5-pre1
by Marcel Wiesweg 30 Mar '05

30 Mar '05

Hi, thanks to the work of Udo Richter I may announce you a preview version of the osdteletext plugin. This version features an extensive rewrite of the display code. This makes the display substantially faster and offers a clean architecture for future development. Additionally, it aims at strict adherence to the standard. Such a rewrite offers many ways for new bugs, so this is a preview release and any bug reports are welcome. The new version is available from: http://www.wiesweg-online.de/linux/vdr/vdr-osdteletext-0.5-pre1.tgz Marcel

HDTV -> mpeg4
by Grégoire Favre 30 Mar '05

30 Mar '05

Hello, just done a small try to convert an Euro1080 FTA preview to mpeg4, with a bitrate of 2500 with mencoder : quality was very bad... Anyone already converted (and keeping the resolution) HDTV with a perfect quality to mpeg4 ? I would be interested in the parameters... -- Grégoire Favre ___________________________________________________________________ http://magma.epfl.ch/Gregoire.Favre mailto:Gregoire.Favre@gmail.com

RE: [vdr] Update for NTSC problem
by Vladimir Shved 30 Mar '05

30 Mar '05

If you look inside of insmod.sh script, you'll see whats loaded and unloaded, I actually had to comment out some modules to keep it cleaner, like modules for USB DVB devices, etc. I think your primary concern right now is to make sure that your built-in DVB kernel modules are unloaded first, then you can worry about loading new ones. > -----Original Message----- > From: vdr-bounces(a)linuxtv.org [mailto:vdr-bounces@linuxtv.org] On Behalf > Of Andrey Vlassov > Sent: Tuesday, March 29, 2005 12:05 PM > To: Klaus Schmidinger's VDR > Subject: Re: [vdr] Update for NTSC problem > > Vladimir, > > I normally unload/load drivers before starting VDR but I never checked > that all drivers have been unloaded. > > I don't have full list drivers which related to DVB-S card to check what > modules should be unloaded.
