How to view the output of log functions like GST_CAT_INFO, GST_DEBUG etc in Android environment? Can I view them in logcat?
回答1:
The log is written to stderr. You can redirect it to a file (2>debug.log) and download it to your computer. There you can just read it using 'less' or 'more'. Alternatively disable the ansi colors (GST_DEBUG_NO_COLOR=1) and use gst-debug-viewer to interactively browse it.

There is a method to redirect stdio to the log so it is visible in logcat:
Redirect stdout to logcat in Android NDK
I have used this several times. I also remount /system read-write on android and edit "/system/build.prop" to add the setting so it survives a reboot. On development platforms, you can even use "vi" within adb shell to edit the file.
