QmlAV

FFmpeg-based real-time QML stream player

To use in your project, you must follow these steps:

1. Get dependencies:

• For Debian

# apt-get install libva-dev libglx-dev libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libswresample-dev libavdevice-dev libgtest-dev

• or for Android

$ cd 3rd/FFmpeg && git submodule update --init
$ export ANDROID_ABI=armeabi-v7a ANDROID_NDK_ROOT=~/Android/Sdk/ndk/21.1.6352462 && ../prebuild_ffmpeg.sh # Supported architectures: armeabi-v7a, arm64-v8a, x86, x86_64

2. Setup your project (Roughly. For details, see https://github.com/iEvgeny/cctv-viewer):

find_package(Qt5 5.12 COMPONENTS Core Quick Multimedia REQUIRED)

add_subdirectory(qmlav)

if (ANDROID)
    add_library(${TARGET} SHARED ${PROJ_FILES} ${QMLAV_FILES})

    target_include_directories(${TARGET} PRIVATE "${CMAKE_SOURCE_DIR}/qmlav/3rd/FFmpeg/ffbuild/${ANDROID_ABI}/include")
    target_link_directories(${TARGET} PRIVATE "${CMAKE_SOURCE_DIR}/qmlav/3rd/FFmpeg/ffbuild/${ANDROID_ABI}/lib")
else()
    add_executable(${TARGET} ${PROJ_FILES} ${QMLAV_FILES})
endif()

target_include_directories(${TARGET} PRIVATE ${QMLAV_INCLUDE})

target_link_libraries(${TARGET} PRIVATE avformat avcodec avutil swscale swresample avdevice)

3. Register the QML type before using:

#include "qmlavplayer.h"

qmlRegisterType<QmlAVPlayer>("QmlAV.Multimedia", 1, 0, "QmlAVPlayer");

...

4. And use this in your QML code:

import QtQuick 2.0
import QtMultimedia 5.0
import QmlAV.Multimedia 1.0

Item {
    VideoOutput {
        id: videoOutput

        source: qmlAvPlayer
        anchors.fill: parent
    }

    QmlAVPlayer {
        id: qmlAvPlayer

        autoPlay: true
        loops: MediaPlayer.Infinite
        source: rtmp://example.ru/stream/name

        avOptions: {
            'probesize': 500000,  // 500 KB
            'analyzeduration': 0  // 0 µs
        }
    }
}
