GST_DEBUG：如何保存日志在一个单独的文件中一个线程的应用程序内 [英] GST_DEBUG: How to save logs in a separate file for a thread inside an application

问题描述

我运行的GStreamer的样本程序，它正在从C ++应用程序作为一个线程调用。已经设置了 GST_DEBUG = *：5 级别来捕获所有可能出现的情况。

I am running a sample program of gstreamer which is being called from a C++ application as a thread. Have set the GST_DEBUG=*:5 level to capture all the possible scenarios.

应用程序也打印在标准输出上很多很多的日志和GStreamer的线程也做了同样的（5级增加了痛苦）。

The application also prints lots and lots of logs on stdout and the gstreamer thread also does the same( the level 5 adds to the misery).

问题 - 有没有办法分离出的GStreamer线程的日志打印在给定的调试级别的文件

Question -- Is there a way to separate out the log printing of gstreamer thread in a file with the given debug level ?

问题补充 - 设置GST_DEBUG_FILE基于以下答案的答案，但该文件由一些字符开始，而不是从GST_DEBUG像

Supplementary question -- Set the GST_DEBUG_FILE based on answer below answer but the file starts from some characters and not from GST_DEBUG like

0:00:00.000036045 ^[[335m21088^[[00m  0x8405800 ^[[37mLOG    ^[[00m ^[[00;01;33m           GST_DEBUG gstinfo.c:1329:for_each_threshold_by_entry:^[[00m category default matches pattern 0x8405570 - gets set to level 5  
0:00:00.000109741 ^[[335m21088^[[00m  0x8405800 ^[[32;01mINFO   ^[[00m ^[[00;01;31m            GST_INIT gst.c:613:init_pre:^[[00m Initializing GStreamer Core Library version 0.10.36

Q2如何从GST删除这些字符，如^ [[和启动？

推荐答案

GST_DEBUG_FILE =的/ tmp / gst.log会把所有记录到该文件中，但单独的日志为单独的线程，你需要编写自己的loghandler。在gstinfo.c一看，gst_debug_add_log_function。

GST_DEBUG_FILE=/tmp/gst.log will put all the logging into that file, but for separate log for separate threads you will need to write your own loghandler. Have a look in gstinfo.c, and gst_debug_add_log_function.

至于你的第二季度，再次，你需要编写自己的loghandler如果你想让它从GST开始，因为这些其他领域（时间戳，进程ID，线程等）都包含在默认loghandler。 （再次看到gstinfo.c，gst_debug_log_default）

As for your Q2, again, you will need to write your own loghandler if you want it to start from GST, since these other fields (timestamp, process-id, thread etc.) are included in the default loghandler. (again see gstinfo.c, gst_debug_log_default)
