I'm before suspect application crash because click next movies twice, or there is happening:Unable to perform first rendering. exception.

but I found , some times you play a lot video file, it's still crash.
and when application crash, visual studio output:return value is -1073741819 (0xc0000005) 'Access violation'。

I was catch it before, but can't catch it now...

there is a video record. please check it:

Video is very boring, the best accelerate playback.

I suspect because stop not stop finish. and play it will be problem. or maybe when play(). I can't pause() Immediately. and clear audio effect(the second crash).

I also find in ffdshow setting can setting the ffdshow Instances count. maybe ffdshow just close, and we open other file, will let it crash......maybe

Is there anyway can quickly change media file. like now :
stop();
//change file
play();
pause();
//do something
Restore();

change to :

//change file
//ReLoad();//do not need stop it, codec do not need quit and load again. do not need set audio or volume or audio effect .

Do you remember the problem:
http://support.visioforge.com/forums/172855-developers-community-help/suggestions/3984709-media-player-is-crash-when-clear-audio-effect-and-

I said:
and I can't use :Player.Audio_Effects_Clear(-1);
because that like before, some times crash.

and I thought you already fixed it.
but looks like some times audio effect still let application crash.

look the video record:
https://www.dropbox.com/s/mta48cha9gn5zxk/crash_prolem.rar

but even I'm remove the code, still crash. and still return Value:-1073741819 (0xc0000005) 'Access violation'。but the crash very like before because audio effect crash....
I don't know why you can't reproduce it.
I don't have money for buy commercial codec.

if ffdshow is a source let the all application crash. I hope you Recommend me other codec or way to handle it. because now I have no any Idea to handle it......

If you are unable to purchase commercial codec - it's doesn't mean that we'll resolve your problems with a free codecs. It's not SDK problems. Elecard codecs can be great choise.

if you confirm it's not you sdk problem , why you just don't recommend to me a other free codec? I give you the record video all because I did not lie, and you know it. I don't have any money for pruchase other commerical codec. I hope you recommend me at least one free codec, and let me test, confirm it's not your sdk problem, and I think this requirement is not excessive.right?

and about the audio decoder, I'm using ffdshow, aac, FLAC....etc.

some times all application stuck, some times crash.

1. 250477278 (0xeedfade)。
2. -1073741819 (0xc0000005) 'Access violation'。

splitter I'm using haali, Gabest.

I don't why what is the source let the crash or stuck happing. video decoder or audio decoder or splitter?

I have not you control.dll source code, so I can't catch it. and find.

-----------------------------

good news is I'm test 3 time LAVFilter splitter (with ffdthow video encoder) today: application not crash. but some times....will stuck....

so I think maybe that's not about video decoder. maybe about use the splitter in your sdk. can you check it please?

I just use other way(just like the sample code last time give you) play next file, and this time not crash in 30 minute. so now I have Idea.

you know every time I'm use this way if want to play next file:

stop();// stop first
//change play list
play();//play it
pause(); pause it

// do some thing. like setting the audio volume, set audio stream, clear audio stream

restore();// and restore it.

and why I'm doing this?? why I'm not just set it all before play.(and not need pause it)
because:http://support.visioforge.com/forums/172855-developers-community-help/suggestions/3985218-audio-volumn-and-audio-stream-and-audio-effect-aut

and today , I'm use this way

stop();

// change the play list . also set the audio stream, audio volume, clear audio effect

play();

and play about 30 minute , change every 3 second, not crash.

so maybe I can use this way. but............
audio volume, audio stream.....all not working.
and effect will let application crash just like you know before.

so can you fixed it . let me use the normal way. I don't need pause it. maybe there is not crash, I think maybe that is a final way. thanks

I think maybe the second crash possibility position is : MediaPlayer.Stop();
because some times it's not crash, will stuck in here.
MediaPlayer picture will suck on last picture before stop. and all application will stuck.
so maybe if there is some asynchronous operation. if media player stop(), but it still execute, so maybe some time stuck...some times crash.....

I finally found a problem where if you look carefully, you will find that switching media file while memory is constantly increasing (different video decoder to increase the situation is different). Eventually lead to two results.
1 Crash
2 stuck.

Please carefully look the record video.

why MediaPlayerSlave must be operate in UI thread?
event I'm not use wpf window . I only use writablebitmap.

but because it need work in UI thread. every time I need use Dispatcher.Invode/beginInvoke

like:

window.Dispatcher.BeginInvoke(new Action(() =>
{
//Play Next
PlayNext(null, null);
}));

actually I'm worry wpf ui thread not let some Asynchronous operations performed immediately.
and let it execute with next same operate, like:
stop();
start();
hold.....
stop();
start();

change to :
stop();
start();
stop();
start();

or let the inside Order confusing

How about this?

you add a method in you api : CustomPlay(String NewMediaPath, int AudioStream, int AudioVlume, bool IsClearVideoEffect, bool IsClearAudioEffect,bool IsAsynchronous)

in the Method inside. you can:

1.check the media player status, if it's not free, the stop it.
2.clear and set the current play list from NewMediaPath param;
3.close all audio stream, and set current audio stream open from AudioStream param;
4.set current Audio volume from AudioVolume param;
5.clear Video or Audio effect use these 2 param;
6.if IsAsynchronous=false. let the all operate stuck all application(At least you ensure the Stability of the system)
7.Play it.

or through own ideas only Released or initialize some resources to optimize it.
Is this will consume a lot of your time?

I really not found any Idea better then......Unless you find WPF crash or stuck problem......

1. Only you have this bug. Other customers do not reported us about this.
2. We unable to reproduce it using latest SDK build, as you see it's fully dispose VideoCaptureSlave class and created new class. So, even if but located in core - it's always new after Stop method call.

1.How can you say that after the 2 month? Other customers not reported not mean there is No this BUG. maybe they are just not using like me. Maybe the requirement not same to you SDK.
2.I give you video record. I give you log. and now the problem source very clear:
VisioForge_Audio_Effects_4.ax or DirectShowLib.ICaptureGraphBuilder2.RenderStream method one of them. How can you still not found it?
3. I already told you , if you're not found let me help. I can let you use my PC to catch it, but you always Not willing for this.
4.You always ignore me, I don't know what are you thinking .

Why you just use My PC find the problem. I can show you how it crash. You even can develope your source code. (use any safe way for you), Now I really don't care you source code. I want the problem resolve. because continue like that, My company will die.

Hello Roman,

I have the same error when the Source mode of the media player is set to VFMediaPlayerSource.File_FFMPEG.
When setting it to VFMediaPlayerSource.File_DS I don't have this issue.
In my application, I am also playing RTSP Stream.To do so, I set the source mode to VFMediaPlayerSource.HTTP_RTSP_FFMPEG, and here again I dont have any problem.

But even I use Halli splitter , it's crash some time, stuck some time. only I know is, if I'm Disable Audio Effect, there is all fine.

I think if I just change the filter not need to change your original interface. even I'm changed the original interface, I still can't change the SDK inside for use it.

So I think maybe you can consider the way I said, and then write these interface your SDK used. and user just need design filter by your interface, and extends the flter class changed the CLSID.

And about Audio effect crash problem, I think I can changed the filter inside, there is some thing I can changed make it more better. I don't need anything else except replace the audio effect CLSID. looks like I even don't need extends the class.

But about the some times play will Crash problem. I still searching the problem source. So I think maybe you can close the ticket to. when I found that crash problem I'll open another ticked.
