RK3588 平臺一直無法讀取視頻

問題描述:
我這邊用的是 rk3588 的核心板，刷的固件里面有 opencv 4.5.5， 系統(tǒng)是 ubuntu 20.04 LTS 版本， 使用 cv::VideoCapture 無法讀取 mp4 或其他視頻，每次讀取后 isOpened() 都是 false;
硬件是 rk3588 對應(yīng)的開發(fā)板
以下編譯安裝直接在開發(fā)板上進行，不是在宿主機用交叉編譯鏈編譯安裝的。

opencv 安裝

下載 opencv4.5.5.zip， 解壓后，在源代碼目錄新建 build 目錄，進入 build 目錄；

確保安裝了相關(guān)依賴

sudo apt-get update

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

sudo apt-get install libatlas-base-dev gfortran 
sudo apt-get install -f ffmpeg   # show video

如果 libjasper 安裝失敗，請往下翻

cd opencv4.5.5
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=~/install/opencv4.5.5 -DBUILD_IPP_IW=OFF -DBUILD_WITH_DYNAMIC_IPP=OFF -DBUILD_JPEG=ON -DBUILD_PNG=ON -DBUILD_TIFF=ON -DBUILD_ZLIB=ON -DBUILD_SHARED_LIBS=ON -DBUILD_opencv_java_bindings_generator=OFF -DBUILD_opencv_python_bindings_generator=OFF -DWITH_MATLAB=OFF -DWITH_LAPACK=OFF -DWITH_FFMPEG=ON     -DWITH_TBB=ON -DWITH_V4L=ON -DWITH_GTK=ON -DWITH_OPENGL=ON -DWITH_IPP=OFF ..
make -j$(nproc)
make install

或者新建一個一鍵編譯安裝的腳本

安裝 libjasper 或許確認這個就可以了

大意了，一開始安裝的時候，沒有太在意這個庫，所以一直重新編都沒有管這個庫；
所以在安裝 opencv 的時候一定要按照步驟來，否則要找很久的問題。
如果上述 opencv 重新編譯安裝還是出現(xiàn)無法讀取視頻的問題，請確保每個依賴庫都已經(jīng)成功安裝。
我相信很多人還是無法讀取視頻，那么就確認這個庫吧。

sudo apt install libjasper1 libjasper-dev

執(zhí)行上述命令會報錯。那怎么辦呢？修改 /etc/apt/source.list

sudo cp /etc/apt/source.list /etc/apt/source.list.bak
sudo gedit /etc/apt/source.list

NOTE: 以下過程是試錯過程，不一定是必要過程，如果上述過程能解決問題，下面就不用管了。

ffmpeg 重新安裝

這里為什么要重新安裝 ffmpeg ？ 翻閱了很多博客，說要重新安裝 ffmpeg.

但是這里也不一定需要重新安裝，重新安裝肯定沒問題。ffmpeg 版本不要安裝太高，因為接口變換較大，可能 opencv 4.5.5 不兼容，我這里試過好幾個版本( ffmpeg 6.0, ffmpeg 5.0.3, ffmpeg 4.4.4)，在重新編譯opencv時都編譯失敗。 ffmpeg 4.2.9 可以成功。

Download FFmpeg
ffmpeg-4.2.9

卸載原裝 opencv

以上還不能解決問題的話，刪除所有 opencv 的安裝，全部重裝。

安裝順序如下：

1. 依賴庫 ( sudo apt install xxx )
2. ffmpeg 源碼編譯安裝
3. 重新編譯安裝 opencv
