Problem after recompiling linphone-android-sdk

[Nicolo-sudo]

Hi there!

I have build my own version of the linphone sdk for android. I wanted to enable the H263 codec, so I recompiled the sdk by passing the -DENABLE_FFMPEG=ON and an .AAR file was built successfully. So I have replaced the previous sdk with my own in the Linphone Android Project. The problem is that in the video settings of the app there are only the H264, H265 and VP8 codecs. Why there isn't the H263 codec?

Thanks in advance

Hi, Please attach logs from the libs and I'll be able to tell you why.

Do you mean the logs of the shell? Because I lost them when I close the window.. I probably need to recompile the sdk again.

After the compilation I found the file wich I have attached. But seems that h263 is not present

disabled_features.txt enabled_features.txt

Thank you for your help

No I'd like the logs of the app. Go into settings->advanced and toggle Debug switch. Then restart the app, go to the About page and click on Upload logs.

Alright, so tomorrow I will try and I will let you know!

Thank you again for your attention

Hi, I have attached the library logs.

What I have done:

• I built my own sdk with this options:

 -DLINPHONESDK_PLATFORM=Android -DENABLE_FFMPEG=ON 
-DENABLE_NON_FREE_CODECS=ON

• I created a symbolic link to the sdk by following this example:

ln -s /linphone-sdk/build/linphone-sdk/bin/outputs/aar/linphone-sdk-android-release.aar linphone-sdk-android/linphone-sdk-android-release.aar

• I built the Linphone App with Android Studio
• I enabled the debug logs in settings of the Linphone app
• I sent logs

This procedure is correct or I have made some mistakes?

[Viish]

Yes this is perfectly right. Did you also add to the cmake options -DENABLE_H263=ON ?

[Nicolo-sudo]

No, as said here (#821 ) i also add -DENABLE_FFMPEG=ON.

I will try again to rebuild the sdk with this option

Thanks

Hi, nothing changed still no H263 codec

[Viish]

Can you add new logs?

Also, after the cmake command, do you see H263 in the enabled features list?

[Nicolo-sudo]

I have made few tests.

If I build with -DENABLE_H263= ON and -DENABLE_FFMPEG=ON the compilation fails after few seconds:

crash_compiling.txt

So I built the new sdk with this options:

cmake -DLINPHONESDK_PLATFORM=Android -DLINPHONESDK_ANDROID_ARCHS=arm64 -DENABLE_NON_FREE_CODECS=ON -DENABLE_H263=ON ..

Unfortunately again there is no H263 feature in this new files:

disabled_features.txt enabled_features.txt

I really need this codec but no luck

[Viish]

You need all those params: -DENABLE_NON_FREE_CODECS=ON -DENABLE_H263=ON -DENABLE_FFMPEG=ON

[Nicolo-sudo]

Okay but the compilation fails if I use all these options together. From logs seems that fails with this error:

No download info given for 'EP_ffmpegandroid' and its source director

To get the SDK sources I used the given git command:

git clone https://gitlab.linphone.org/BC/public/linphone-sdk.git --recursive

Probably is something wrong with my configuration? But why in other cases everything goes fine?

Thank you very much for your help

No, sadly you are in the current case where ffmpeg doesn't build anymore (I guess you have a recent NDK). We have no plan to make it work again for now, but if you manage I'll gladly merge a patch.
