new codec plugin add error!

[liyake825]

I have got the libxxx-plugin.dll after my successfully compiling the new codec.
I also can saw my codec enabled when i finished configure the whole project.
But when I want to play a video coded by my own codec , it appears that the plugin has not been loaded corretly, even the libxxx-plugin.dll is just in the plugins file.
Why?
Who can help me ?

Look at the debug messages log with something like

Code: Select all

vlc -vvv

You could try using a different interface like the dummy one:

Code: Select all

vlc -vvv -I dummy INPUT

Where INPUT is your input. Then you should see the output in a separate cmd window.

Or use the logger module to log to a file. In VLC, using the Qt4/default interface, go to:
Tools >> Preferences >> (Select "All" for "Show settings") >> Interface

And check "Log to file". Set the Verbosity to 2. Then you need to say where you want to put the file. This is in the "Advanced >> Logging" section of the Preferences. Enter a file name, and set the "Verbosity" to 2 again (for good measure ). Then press "Save", close VLC and when you reopen it logging should be enabled and also VLC should write the logs to the file you specified.

Thank you very much for reply . Arite.
I am sorry, I can not get your mean because I am fresh about this. What is your mean about "use the logger module to log to a file" ? Does this aim at helping me about loading my new codec module or the comand lines?

edwardw said to look at the debug messages - they should hopefully tell you where/when/why your plugin isn't loading/has an error.

I just said a couple of different methods of gettting the messages (on Windows). If you do this:

In VLC, using the Qt4/default interface, go to:
Tools >> Preferences >> (Select "All" for "Show settings") >> Interface

And check "Log to file". Set the Verbosity to 2. Then you need to say where you want to put the file. This is in the "Advanced >> Logging" section of the Preferences. Enter a file name, and set the "Verbosity" to 2 again (for good measure ). Then press "Save", close VLC and when you reopen it logging should be enabled and also VLC should write the logs to the file you specified.

Then you should be able to open VLC and all the logs will be written to the file you specified. Have a look through them and it should give you information about codec module etc.

Alternatively you could use a different interface like the dummy one.

Yes, i got your mean .Thank you very much!
I found that it was my library(libxxx.a) i used for decode is not good, but that library can pass the compilation , but it can not be seen in the interface .I have just make through it yesterday by creating a new library, now I can see my video codec in the qt interface.But it still can not work now , everytime i use this new module to decode a video sequence , it will crash.
