I have a mp4 file and need the profile level of it. FFmpeg says, it has baseline profile, which is what I need, but I need also the level.
Here is what I get from FFmpeg:

At least one output file must be specified
Is there any option other than -i
I can use to get the level information?
ffprobe with show_entries command should be faster, and it has more options to show only relevant data and to filter only video stream.
to filter only video (add also :0 to filter only first video stream)
ffprobe -v error -select_streams v:0 -show_entries stream=level -of default=noprint_wrappers=1 <filepath>
e.g. OUTPUT:
level=50
to output only the value (add :nokey=1):
ffprobe -v error -select_streams v:0 -show_entries stream=level -of default=noprint_wrappers=1:nokey=1 <filepath>
e.g. OUTPUT:
50
to output both Profile and Level in one go:
ffprobe -v error -select_streams v:0 -show_entries stream=profile,level -of default=noprint_wrappers=1 <filepath>
e.g. OUTPUT:
profile=High
level=50
to output in json format:
ffprobe -v error -select_streams v:0 -show_entries stream=profile,level -of json <filepath>
e.g. OUTPUT:
{
"programs": [
],
"streams": [
{
"profile": "High",
"level": 41
}
]
}
in a MS batch file (as fake function):
call :ffprobeGetFormatProfile ffprobe.exe file.mp4 txtFormat
:ffprobeGetFormatProfile <exe> <infile> <outStr>
echo.
echo FILE: %2
set tmpProfile=
set tmpLevel=
for /f "usebackq delims== tokens=1-2" %%a in (`%~s1 -v error -select_streams v:0 -show_entries stream^=profile^,level -of default^=noprint_wrappers^=1 %2`) do (
if /I %%a == profile set tmpProfile=%%b
if /I %%a == level set tmpLevel=%%b
)
if not defined tmpLevel set tmpLevel=??
echo on
set %3=%tmpProfile%@%tmpLevel:~0,1%.%tmpLevel:~1%
@echo off
exit /b %errorlevel%
e.g. OUTPUT (in a variable txtFormat passed as 3rd argument):

You can get some more ideas from ffmpeg.org - Tips
Try ffprobe -show_streams
.
ffprobe
is bundled with FFmpeg and gives lots of information about video files including level information, e.g.:
$ ffprobe -loglevel error -show_streams Test.mp4
