  • FFMPEG 2.5.4 build for Android with NDK r10d

    7 décembre 2015, par jmartinalonso

    I'm trying to build FFmpeg for android following this tuto: http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/

    I'm using:

    • NDK r10d
    • FFMPEG 2.5.4

    I have tried to build on MacOs and Ubuntu and I get the same error when I execute ./build_android.sh:

    `Creating config.mak, config.h, and doc/config.texi...
./build_android.sh: line 16: --prefix=/Users/jesusmartin92/Documents/android-ndk-r10d/sources/ffmpeg-2.5.4/android/arm: No such file or directory

./build_android.sh: line 48: --extra-cflags=-Os -fpic -marm: command not found
./build_android.sh: line 50: --extra-ldflags=: command not found`

    It's like the script doesn't find the ndk folder, but I checked and the path is OK. The script "build_android.sh" is in the ffmpeg folder. This is the content of it: 

    #!/bin/bash
NDK=/Users/jesusmartin92/Documents/android-ndk-r10d
SYSROOT=$NDK/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
function build_one
{
./configure \
    --prefix=$PREFIX \
    --enable-shared \
    --disable-static \
    --disable-doc \
    --disable-ffmpeg \
    --disable-ffplay \
    --disable-ffprobe \
    --disable-ffserver \
    --disable-avdevice \
    --disable-doc \
    --disable-symver \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --target-os=linux \
    --arch=arm \
    --enable-cross-compile \
    --sysroot=$SYSROOT \
    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \
    $ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU 
ADDI_CFLAGS="-marm"
build_one

    I'm very stuck, so any idea will be well received.

    Thanks

  • How to convert any video type to .mp4 using phpvideotoolkit

    7 décembre 2015, par user3653474

    I am following this http://www.phpclasses.org/package/3747-PHP-Manipulate-and-convert-videos-with-ffmpeg-program.html link to convert any video type to .mp4 i tried to run various example files but they are throwing error message. I can't get how to convert the file using phpvideotoolkit.

    If i run the following file http://localhost/phpvideotoolkit-v2-master/examples/convert-to-multiple-outputs.php i get this error.

    An error was encountered with FFmpeg when attempting to read the formats that FFmpeg supports. FFmpeg reported: The system cannot find the path specified.

  • Transcoding via FFmpeg. Set starting pcr value

    7 décembre 2015, par Ivan Kolesnikov

    I transcoding via FFmpeg (video codec - h264, container - MPEG-TS) output writing to local file (out.mpg). When FFmpeg dropped I restarted it with output to the same file (out.mpg). After this my video player shows incorrect file duration due to new FFmpeg process start counting PCR from 0.
    Can I set starting pcr value at start FFmpeg ?

  • Android : FFmpegFrameRecorder (JavaCV) UnsatisfiedLinkError

    7 décembre 2015, par Olcay Ertaş

    I am trying to record video using OpenCV with some overlayed data. I have added OpenCV to my project and get camera preview successfully. While searching for how can I record video I came across to JavaCV. JavaCV has a sapmle activity called RecordActivity to demostrate video recording. It adds a CameraView dynamically with code and get camera frames and record them in onPreviewFrame method of the CameraView. You can see the full code here:

    RecordAvtivity.java

    What I want to do is record video in onCameraFrame metod of the CvCameraViewListener2 interface instead of onPreviewFrame metod of the PreviewCallback.

    public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
    final Mat rgba = inputFrame.rgba();
    Core.flip(rgba, rgba, 1);
    // Overlay some text and record video here.
    return rgba;
}

    JavaCV record code block from RecordAvtivity.java

    public void onPreviewFrame(byte[] data, Camera camera) {

    if (audioRecord == null || audioRecord.getRecordingState() != AudioRecord.RECORDSTATE_RECORDING) {
        startTime = System.currentTimeMillis();
        return;
    }

    int i = imagesIndex++ % images.length;
    Frame yuvImage = images[i];
    timestamps[i] = 1000 * (System.currentTimeMillis() - startTime);

    /* get video data */
    if (yuvImage != null && recording) {
        ((ByteBuffer) yuvImage.image[0].position(0)).put(data);

        try {
            Log.v(TAG, "Writing Frame");
            long t = 1000 * (System.currentTimeMillis() - startTime);

            if (t > recorder.getTimestamp()) {
                recorder.setTimestamp(t);
            }

            recorder.record(yuvImage);
        } catch (FFmpegFrameRecorder.Exception e) {
            Log.v(TAG, e.getMessage());
            e.printStackTrace();
        }
    }
}

    JavaCV needs data as byte[] but I have Mat object. I need to cenvert between them efficiently.

    How can I do that?

    UPDATE:

    I have used following solution to solve my initial problem

    public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
    final Mat rgba = inputFrame.rgba();
    Core.flip(rgba, rgba, 1);

    if (data == null) {
        data = new byte[(int)rgba.total() * rgba.channels()];
    }

    rgba.get(0,0, data);
    record(data);
    return rgba;
}

public void record(byte[] data) {

    if (audioRecord == null || audioRecord.getRecordingState() != AudioRecord.RECORDSTATE_RECORDING) {
        startTime = System.currentTimeMillis();
        return;
    }

    int i = imagesIndex++ % images.length;
    Frame yuvImage = images[i];
    timestamps[i] = 1000 * (System.currentTimeMillis() - startTime);

    /* get video data */
    if (yuvImage != null && recording) {
        ((ByteBuffer) yuvImage.image[0].position(0)).put(data);

        try {
            Log.v(TAG, "Writing Frame");
            long t = 1000 * (System.currentTimeMillis() - startTime);

            if (t > recorder.getTimestamp()) {
                recorder.setTimestamp(t);
            }

            recorder.record(yuvImage);
        } catch (FFmpegFrameRecorder.Exception e) {
            Log.v(TAG, e.getMessage());
            e.printStackTrace();
        }
    }
}

    but now I am getting following error:

    I have tried solution from below question but it didn't work:

    JavaCV configuration in Android Studio

    I have also tried both manual and gradle install for JavaCV but none of them worked.

    I am using:

    • Android Studio 1.4
    • OpenCV 3.0
    • JavaCV 1.0
