Hi,

I am using VLC to open up a file and stream the contents (UDP) to an ip address and have this part working well.

It is possible to change the playback rate of the file? i.e. I would like to slow the video that is being streamed down to half speed?

Cheers,

Chris

It didn't help on my core 2 duo machine. Should this problem now be moved into official Trac bug reporting?

using about 30-40% cpu on both cores at the moment main warning: picture is too late to be displayed (missing 21 ms) main debug: picture might be displayed late (missing 13 ms) main debug: auto hiding mouse cursor main warning: picture is too late to be displayed (missing 36 ms) main debug: picture ...

I have tested 2.0.1 official and I still get the high cpu too

I also have this problem, and have tried the 2.0.1 nightly builds and its still there, has the audio fix not gone in yet or is there another problem?

to be honest i can see much difference between all the 1.1.x versions - all about the same

Just the huge leap going from 1.1.x -> 2.0.x

out of interest I just changed the video output to be DirectX instead of Default (which i think used Direct3D) and i have clawed back some of the performance, but not all.

I am also seeing very high CPU with 2.0.0 and 2.0.1 (NB) on windows xp With 1.1.x the cpu per vlc video stream (720x576 UDP) is about 10%, with 2.0.x it is over 30% I tried to disable the two dll files mentioned earlier and it did not help me. Has anyone got another other suggestions? Chris Core 2 D...

yeah you're right, not sure how i managed to get it into a state when it worked buy it def has the same issues now

I just tried pre3 and this appears to be fixed now. Thanks

Hi, I have been playing with the latest 1.2.0 Nightly build, and have been getting a crash when trying to stop and close my libvlc instance and media player shortly after playing a new video. It appears to be related to the text that appears on video playing as adding the option "--no-video-tit...

Hello, I am playing mulitple udp streams within libvlc and what appears randomly i get access violations in libfreetype_plugin.dll (read of address 00000000) in both vlc 1.1.9 and vlc 1.1.6. Any ideas? The call stack is as follows libfreetype_plugin ntdll.dll - TrlGetNtGlobalFlags ntdll.dll - RtlLea...

did you get anywhere with this?

Hi, When using the official VLC app to view DVB-T, all i need to do is enter in the frequency and symbol rate. Then to view the different broadcasts on the same frequency I can go to Playback -> Programme and change to a different channel. E.g. In the UK the BBC is broadcast at 506000Khz, and then a...

no, i use the standard vlc install. I got the stack trace by building my exe with Eurekalog. (http://www.eurekalog.com/index_delphi.php)

Hi, I apologise for the length of this post but i am not sure how to fix or work around a problem, and any help would be much appreciated. I have embedded vlc 1.1.9 using calls to libvlc into my application and it is viewing a multiple udp video streams. The streams come from a digital tv source tha...

I have seen similar problems with 1.1.5 and 1.1.6 in Delphi.

Can you remove the libfluidsynth_plugin.dll from the plugins folder (C:\Program Files\VideoLAN\VLC\plugins), and then try your app and get back to me to see if it still occurs?

Hi JB,

I also get this behaviour with 4+ instances with Win32 with 1.1.5, although the app has to be compiled for it to trigger, when running the app from debug mode in my Delphi IDE it never happens (i presume the IDE slows down the calls to play just enough so the deadlock doesn't occur)

I have just seen a huge spike in memory usage, it has now gone from 150mb to 750mb. The video appears to have now stopped, and i found lots of these the log 1|main|Failed to grab a snapshot 2|main|late picture skipped (4704550 > -10) 1|main|picture allocation failed 1|main|pictures leaked, resetting...

sorry, I was looking at old source code. I have the latest now.

I do still have a memory leak with 1.1.5 however, in 4 hrs the usage in task manager has gone from 50mb to 150mb. (win xp)

Hi, I have an application which plays a video stream and saves a png image to file every 1 sec by calling libvlc_video_take_snapshot. I have noticed that over time the amount of memory consumed by my app increases at a linear rate. Looking at the source code forlibvlc_video_take_snapshot , a call to...

sorry my bad, i hadn't changed my call into the dll to be cdecl

thanks, so no benefits but are there any drawbacks other than the extra source code? i.e. more memory usage, more threads etc?

Hi, I am building an Win32 application that display four videos using four libvlc_media_player_t. Please could someone list the advantages and disadvantage of using separate calls to libvlc_new to create four instances of LibVLC, or to make 1 call to libvlc_new and three calles to libvlc_retain to c...

Hi,

Using VLC 1.1.5, libvlc_media_player_is_playing is always returning zero for me? even tho libvlc_media_player_get_state = libvlc_Playing, anyone else get this?
