debug

# Name Description
0 none No debug information is output.
1 ERROR Logs all fatal errors. These are errors that do not allow the
core or elements to perform the requested action. The
application can still recover if programmed to handle the
conditions that triggered the error.
2 WARNING Logs all warnings. Typically these are non-fatal, but
user-visible problems are expected to happen.
3 FIXME Logs all "fixme" messages. Those typically that a codepath that
is known to be incomplete has been triggered. It may work in
most cases, but may cause problems in specific instances.
4 INFO Logs all informational messages. These are typically used for
events in the system that only happen once, or are important
and rare enough to be logged at this level.
5 DEBUG Logs all debug messages. These are general debug messages for
events that happen only a limited number of times during an
object's lifetime; these include setup, teardown, change of
parameters, etc.
6 LOG Logs all log messages. These are messages for events that
happen repeatedly during an object's lifetime; these include
streaming and steady-state conditions. This is used for log
messages that happen on every buffer in an element for example.
7 TRACE Logs all trace messages. Those are message that happen very
very often. This is for example is each time the reference
count of a GstMiniObject, such as a GstBuffer or GstEvent, is
modified.
9 MEMDUMP Logs all memory dump messages. This is the heaviest logging and
may include dumping the content of blocks of memory.

tiny (if you don't want install webserver like nginx)

./tiny port

ramdis optimize

if you runing hls you can create a ramdisk for it

create folder

sudo mkdir -p /media/ramdisk

mount it

sudo mount -t tmpfs -o size=256M tmpfs /media/ramdisk

unmount it

sudo umount /media/ramdisk

auto mount when boot

sudo vim /etc/fstab none /media/ramdisk tmpfs nodev,nosuid,noexec,nodiratime,size=256M 0 0
