ffmpeg安装ERROR: cuvid requested, but not all dependencies are satisfied: ffnvcodec

ERROR: cuvid requested, but not all dependencies are satisfied: ffnvcodec If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. 解决方法:安装NVIDIA headers git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git make sudo make install 然后重新configure: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --extra-cflags='-I/home

infinite loop database check

試著忘記壹切 提交于 2019-12-04 03:57:13
问题 I'm using JDBC, need to constantly check the database against changing values. What I have currently is an infinite loop running, inner loop iterating over a changing values, and each iteration checking against the database. public void runInBG() { //this method called from another thread while(true) { while(els.hasElements()) { Test el = (Test)els.next(); String sql = "SELECT * FROM Test WHERE id = '" + el.getId() + "'"; Record r = db.getTestRecord(sql);//this function makes connection,

How to enable H2 Database Server Mode in Spring Boot

走远了吗. 提交于 2019-12-04 03:53:49
问题 I'm using a H2 database with a file using Spring Boot. In my application.properties, I have this entry: spring.datasource.url=jdbc:h2:file:c:/Testprojekte/spring-boot-h2-db But now I would like to be able to look at the database while running the application, which currently isn't possible because I need to have the database running in server mode in order to do so. In the documentation I found that I have to add AUTO_SERVER=TRUE to the URL but this doesn't solve the problem. So, what do I

Spring Data JPA Unable to locate Attribute with the the given name

老子叫甜甜 提交于 2019-12-04 03:44:49
I was trying to use Spring Data JPA on Spring Boot and I kept getting error, I can't figure out what the problem is: Unable to locate Attribute with the the given name [firstName] on this ManagedType [com.example.h2demo.domain.Subscriber] FirstName is declared in my entity class.

My Entity class (getters and setters are also in the class) : @Entity public class Subscriber { @Id @GeneratedValue private long id; private String FirstName,LastName,Email; public Subscriber(long id, String firstName, String

How to find if a column name is a reserved keyword across various databases

孤街浪徒 提交于 2019-12-04 03:24:25
问题 We have a legacy schema file which has the following column names, would like to understand if any of them would cause an issue if we port our application to h2, mysql, postgres or oracle. e.g how would I know if using this would be ok across the databases listed below. Are there any good tools which can do a preliminary check on this? key when size type count from with 回答1: Should be quite easy to get the list of reserved words and build a table of the reserved words. Here are some lists of

Spring Boot. @DataJpaTest H2 embedded database create schema

末鹿安然 提交于 2019-12-04 02:48:49
问题 I have couple of entities in my data layer stored in particular schema. For example: @Entity @Table(name = "FOO", schema = "DUMMY") public class Foo {} I'm trying to setup H2 embedded database for integration testing of my data layer. I'm using @DataJpaTest annotation for my tests to get H2 embedded database configured automatically. However, the creation of tables fails because schema DUMMY is not created at DB initialization. Any ideas on how to create schema before creation of tables in

How to CREATE PROCEDURE in H2

ぐ巨炮叔叔 提交于 2019-12-04 02:33:05
This seems to be a duplicate of the other question with the same title, but it actually isn't. We have our business logic implemented mostly as DB2 stored procedures (I see that H2 has a DB2-compatibility mode - nice!). How can we use H2 for in-memory unit testing with these procedures? Unfortunately H2 seems to lack the CREATE PROCEDURE command from its grammar . I don't want to use Java functions as stored procedures . It would be best if the very same sql files could be used for testing and production as well... am I asking too much? EDIT: we also use SQL cursors... again, no sign of

H2 “runscript” command turns all table names into uppercase

爱⌒轻易说出口 提交于 2019-12-04 01:55:39
I have a sql script (it is just schema definition). The script is a modified version (getting rid of the bad characters h2 doesn't like) of a mysql dumb. The script runs and the schema is inserted into the h2 database, but the issue is that all of the database names are in uppercase ('xyz' gets converted to 'XYZ'). I need them to stay in lowercase because my application is looking for the lowercase (and all of the tables in the mysql db are lowercase). Why is this happening? How can I tell h2 to not do that? Is there a better way to insert schema definition into h2? This is the INT command I'm

Setup password for H2

一个人想着一个人 提交于 2019-12-04 01:52:06
How to set up my own password for accessing the h2 while working in embedded mode? (if anyone confused - talking about the root password for accessing the database) In Eclipse it seems that password assignment occurs at the moment of db connection creation which in turn launches the process of schema creation, where we provide username and password. Even if this is true how to change existing password after set up? I've searched in information schema - found `users', there is no password column though. The process seems to be really weird, what am I missing. In PostgreSQL it is a way easier.

Can't see my H2 database in Web Console

不问归期 提交于 2019-12-04 00:50:14
问题 I created a H2 database with my code with this URL: jdbc:h2:C:/data/fixed.db My code can create tables, perform queries. If I open the file manually, I can successfully see its content and view the create queries etc However, when I try to use H2 console with the web interface, I can't see the database.
