rtmpts / rtmps / crypto protocol on ffmpegframegrabber / ffmpegframerecorder support with libspeex about javacpp-presets HOT 15 CLOSED

Looks great! Do you think you could do the same for the rest of the non-Windows platforms and send that over via a pull request? (Along with a one-liner in the CHANGELOG.md file with your name, if desired.) Thanks!

I will do that when i'm done finishing the implementation.
i still need a little help from you.

I'm trying to find a way to include the libspeex.so, libcrypto.so and libssl.so in the generated ffmpeg-android-arm.jar but i cannot find how.

can you provide a hint?

from javacpp-presets.

The easiest thing would be to compile them as static libraries, but if you really want to use shared libraries, we might as well make a completely separate artifact out of those. Which wouldn't be a bad thing when you think about it. Is this something you'd like to try? I have to write a tutorial about that anyway.

Or if not, are there any reasons to not use use static libraries?

from javacpp-presets.

trying to compile as static right now... i will let you know if everything went ok. thanks

from javacpp-presets.

Well i have some issues right know.
still building them as shared libraries, and i get

dlopen("/data/app-lib/xxxx/libjniavformat.so") failed: dlopen failed: cannot locate symbol "avio_find_protocol_name" referenced by "libjniavformat.so"...
Caused by: java.lang.UnsatisfiedLinkError: Couldn't load gnustl_static from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/xxxx.apk"],nativeLibraryDirectories=[/data/app-lib/xxxx, /vendor/lib, /system/lib]]]: findLibrary returned null

edit: i get the same error also when building static libraries.

from javacpp-presets.

Are you saying that you get that error without your additions? Or does this only happen with your additions? If this happens only with your additions, could you please provide the modifications you made to the files? Thanks

from javacpp-presets.

after some failed attempts to get my code to work(without luck), i downloaded
JavaCV 0.8 binary package javacv-0.8-bin.zip from
http://search.maven.org/remotecontent?filepath=org/bytedeco/javacv/0.8/javacv-0.8-bin.zip

replaced all the .so files im my armeabi folder,
replaced artoolkitplus.jar, ffmpeg.jar, javacpp.jar, javacv.jar, opencv.jar from the downloaded file
and i get the same error:

dlopen("/data/app-lib/xxxx/libjniavformat.so") failed: dlopen failed: cannot locate symbol "avio_find_protocol_name" referenced by "libjniavformat.so"...

from javacpp-presets.

So, you are saying that you have issues with the binaries of release 0.8?
If so, could you provide the problematic sample code so I can reproduce the
problem here? Thanks!

from javacpp-presets.

Finally, it works. There is nothing wrong on your side, i had to System.loadLibrary my extra libraries.
on the 0.7 they are loading fine without the System.loadLibrary.
Weird.

So sorry for the trouble.
Right know my enhancement works, but you have to cp libcrypto.so,libssl.so and libspeex.so by hand in the armeabi-v7a folder and do:

System.loadLibrary("crypto");
System.loadLibrary("ssl");
System.loadLibrary("speex");
rec = new FFmpegFrameRecorder(rtmps_link,width,height,1);
...
rec.setFormat("flv");
rec.setVideoCodec(avcodec.AV_CODEC_ID_H264);
rec.setAudioCodec(avcodec.AV_CODEC_ID_SPEEX);
...

from javacpp-presets.

So, are you saying those cannot be linked statically?

from javacpp-presets.

Samuel, right know i cannot test it due time issues,have to finish some tests at work :)
I will try to build them as static libraries, and when succeed i will let you know.
Thanks again.

from javacpp-presets.

Be sure to let me know how that goes, thanks!

from javacpp-presets.

I just added speex support on my branch, probably even that can be ported back.

from javacpp-presets.

Great! Clean it up and send a PR, thanks!

from javacpp-presets.

@ratmole @lu-zero I've added those in version 0.10, thanks for helping out with this!
