我想在java动态Web应用程序中使用Quartz 2.2创建一个调度程序.我是这项任务的新手.我尝试了网络上的所有教程.我尝试上下文监听器方法来初始化调度程序.它似乎不起作用.hello world程序仅适用于一般的java应用程序.对于Web应用程序,它看起来很棘手.

我正在尝试这篇博文。我是 python、numpy 和 FFMPEG 的新手。我无法弄清楚是什么导致了这个问题。

http://zulko.github.io/blog/2013/09/27/read-and-write-video-frames-in-python-using-ffmpeg/

这是代码：

import subprocess as sp
import numpy

print ("Hello World!");
FFMPEG_BIN = "ffmpeg" # on Linux ans Mac OS
#FFMPEG_BIN = "ffmpeg.exe" # on Windows

command = [ FFMPEG_BIN,
            '-i', '/Users/eananthaneshan/Movies/myvideo.mp4',
            '-f', 'image2pipe',
            '-pix_fmt', 'yuv444p',
            '-s', '420x360',
            '-r', '24',
            '-vcodec', 'h264', '-']
pipe = sp.Popen(command, stdout = sp.PIPE, bufsize=-1)

# read 420*360*3 bytes (= 1 frame)
raw_image = pipe.stdout.read(420*360*3)
# transform the byte read into a numpy array
image =  numpy.fromstring(raw_image, dtype='uint8')
image = …

我尝试通过导入项目向导导入,没有用.这个项目正在使用Gradle Kotlin DSL.我使用的是Android Studio 3.1.4.

我试着跑步gradle idea并收到了这条消息

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/user/Projects/firebaseauthui/FirebaseUI-Android/build.gradle.kts' line: 400

* What went wrong:
SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

导入此项目的推荐方法是什么,因为他们已迁移到Kotlin DSL？

这已在GitHub Repository上报告过.我还有问题导入.
