We Keep Coding

s_sec, s_millisec = divmod(float(entry['start']), 1) KeyError: 'start' for max_word= 1

I worked on code published on GitHub https://github.com/jrterven/audio-visual-dataset/blob/master/extract_detailed_text_watson.py the code was design to use 5 words but I want to change it to 1 word so I try do that in the code but there is an error in the run as shown below

Creating video from list of images using ffmpeg

Summary
From given code, second function taking UI values and passing to first one. from log, first two lines shows command list and command string.
What's irritating me is, if I copied second line from log (dos cmd) and paste it in a cmd prompt, it works successfully and produces video correctly. but running it via gui subprocess, errors out.
Task Description
Directory contains thousand of images each after few minutes of a construction project. I need to create a video from data (images) per day basis. I have successfully extracted list of images, etc, and have data.

subprocess call of ffmpeg returns negative value

Here is the original command line call that works at shell:
ffmpeg -i /Users/abc/Desktop/Test/Full_Mov.mov -vf "drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf: text='SCENE BLAH BLAH - %{frame_num}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: fontsize=20: box=1: boxcolor=black: boxborderw=5","format=yuv420p" -f segment -segment_frames 123 -reset_timestamps 1 -c:a copy -map 0 "/Users/abc/Desktop/Test/%03d_test40.mov"
Getting a negative value when trying to run ffmpeg via subprocess, causing it to fail and not process. I've even tried dumbing down the call to just run ffmpeg by itself with no arguments, and it still returns a negative value.
import subprocess
ffmpeg = "/usr/local/bin/ffmpeg"

destination = "/Users/abc/Desktop/Test/%03d_test40.mov"

log("ffmpeg cmd: %s" % cmd)
log(subprocess.check_output(cmd, shell=True))
When running full command:

ffmpeg command line is tricky as there are a lot of special arguments and mistakes are sometimes difficult to understand, the program sometimes interprets/discards wrong arguments, resulting in cryptic error messages.
Another difficulty is using check_output. You don't really need to do this, and if the program fails you won't have any output at all.
I would try the following (that I could not test), which is to:
drop shell=True
pass a list of arguments instead of composing the string yourself. It allows to forget about the quoting/escaping. You don't need to format the command, source & destination since they're standalone arguments:
Don't log, just print with check_call.
As a bonus, you'll get the output in real-time, instead of in the end...
note that I have removed the single quotes in "text=SCENE BLAH BLAH - %{frame_num}:, too and unescaped the % char.
like this:
cmd = [ffmpeg,"-i",source,"-vf",
"drawtext=fontfile=/System/Library/Fonts/Keyboard.ttf:",
"text=SCENE BLAH BLAH - %{frame_num}: start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=black: fontsize=20: box=1: boxcolor=white: boxborderw=5: format=yuv420p",
"-f","segment","-segment_frames","123",
"-reset_timestamps","1","-c:a","copy","-map","0",destination]
log("ffmpeg cmd: %s" % cmd)
rc = subprocess.check_call(cmd)
if rc:
raise Exception("ffmpeg failed")
for the case of ffmpeg, you could migrate to ffmpeg python module. Could save some argument parsing trouble too.

Using subprocess on Popen option

I use python 2.7 and ffmpeg on Mac OS 10.10.
When use some command from python, coded like below
p = subprocess.Popen(cmd.strip().split(" "))
This goes well all the time, but not in ffmpeg filter_complex case.
Below code can run on the terminal with directly input.
ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex " nullsrc=size=1920x1440 [base]; [0:v] setpts=PTS-STARTPTS, scale=1920x1440 [frame0];[1:v] setpts=PTS-STARTPTS, scale=640x480 [frame1]; [base] [frame0] overlay=shortest=1:x=1920:y=1440 [tmp1]; [tmp1] [frame1] overlay=shortest=1:x=640:y=480 output.mp4
But cannot run with python Popen script like below.
cmd = "ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex " nullsrc=size=1920x1440 [base]; [0:v] setpts=PTS-STARTPTS, scale=1920x1440 [frame0];[1:v] setpts=PTS-STARTPTS, scale=640x480 [frame1]; [base] [frame0] overlay=shortest=1:x=1920:y=1440 [tmp1]; [tmp1] [frame1] overlay=shortest=1:x=640:y=480 output.mp4"
p = subprocess.Popen(cmd.strip().split(" "))
This has problem at split(" ") works unexpected subdivision.
So I prepare the split command directly like
split_cmd = [ffmpeg_exe,'-i','input1.mp4','-i','input2.mp4','-filter_complex','\" nullsrc=size=1920x1440 [base]; [0:v] setpts=PTS-STARTPTS, scale=1920x1440 [frame0];[1:v] setpts=PTS-STARTPTS, scale=640x480 [frame1]; [base] [frame0] overlay=shortest=1:x=1920:y=1440 [tmp1]; [tmp1] [frame1] overlay=shortest=1:x=640:y=480\"','output.mp4'];
p = subprocess.Popen(split_cmd)
Even in this case, system return
[AVFilterGraph # 0x7fb1c9f000c0] No such filter: '" nullsrc'
Error configuring filters.
this could be system confused the -filter_complex option as ffmpeg option.
Anyone can help this, please.

You are actually passing in the opening and closing double-quote ", since there is no shell in-between that uses them. Use just
' nullsrc=size=1920x1440 [base]; [0:v] setpts=PTS-STARTPTS, scale=1920x1440 [frame0];[1:v] setpts=PTS-STARTPTS, scale=640x480 [frame1]; [base] [frame0] overlay=shortest=1:x=1920:y=1440 [tmp1]; [tmp1] [frame1] overlay=shortest=1:x=640:y=480'
instead, i.e. without the opening and closing \".
split_cmd = [ffmpeg_exe,'-i','input1.mp4','-i','input2.mp4','-filter_complex',' nullsrc=size=1920x1440 [base]; [0:v] setpts=PTS-STARTPTS, scale=1920x1440 [frame0];[1:v] setpts=PTS-STARTPTS, scale=640x480 [frame1]; [base] [frame0] overlay=shortest=1:x=1920:y=1440 [tmp1]; [tmp1] [frame1] overlay=shortest=1:x=640:y=480','output.mp4']
You can also try using shlex.split, as described in the subprocess documentation.

How do I parse lines from a log file?

I need to extract the values of following output:
Oct 6 17:29:52 FW kernel: [ 5470.058450] ipTables: IN= OUT=eth0 SRC=192.168.1.116 DST=192.168.1.110 LEN=516 TOS=0x10 PREC=0x00 TTL=64 ID=4949 DF PROTO=TCP SPT=22 DPT=46216 WINDOW=446 RES=0x00 ACK PSH URGP=0
I'd need for example the value of PROTO stored in a value. tried shellscripting, my problem is that it works only if the log entry is in the same order everytime.
so this doens't work:
while read line
do
in_if=`echo $line | cut -d ' ' -f 10 | cut -d '=' -f 2`;
out_if=`echo $line | cut -d ' ' -f 11 | cut -d '=' -f 2`;
src_ip=`echo $line | cut -d ' ' -f 12 | cut -d '=' -f 2`;
dst_ip=`echo $line | cut -d ' ' -f 13 | cut -d '=' -f 2`;
pro=`echo $line | cut -d ' ' -f 20 | cut -d '=' -f 2`;
echo "$in_if,$out_if,$src_ip,$dst_ip,$pro" >> output.csv;
done < $tmp_file

Python does this conveniently. A general solution that gets all the KEY=value pairs is:
import re
import fileinput
pair_re = re.compile('([^ ]+)=([^ ]+)') # Matches KEY=value pair
for line in fileinput.input(): # The script accepts both data from stdin or a filename
line = line.rstrip() # Removes final spaces and newlines
data = dict(pair_re.findall(line)) # Fetches all the KEY=value pairs and puts them in a dictionary
# Example of usage:
print "PROTO =", data['PROTO'], "SRC =", data['SRC'] # Easy access to any value
This is arguably more legible, flexible and convenient than a shell script.

You can do this without touching Perl. You were on the right track, but with a regex you can search by name, not position.
Also, you should put quotes around $line so you don't get burned by any pipes or semicolons hanging around.
pro=`echo "$line" | grep -o 'PROTO=\w+\+' | cut -d '=' -f 2`;
Of course, if you did want to use Perl, you could make a much slicker solution:
#!/usr/bin/perl
while(<>) {
/IN=(\S*) .*OUT=(\S*) .*SRC=(\S*) .*DST=(\S*) .*PROTO=(\S*)/
and print "$1,$2,$3,$4,$5\n";
}
Then call:
./thatScript.pl logFile.txt >>output.csv

you don't even need to cut:
grep -Po "(?<=PROTO=)\w+" yourFile
OR
sed -r 's/.*PROTO=(\w+).*/\1/' yourFile
OR
awk -F'PROTO=' '{split($2,a," ");print a[1]}' yourfile

A straightforward Perl solution might be the most readable one:
#!/usr/bin/env perl
use strict; use warnings;
my $s = q{Oct 6 17:29:52 FW kernel: [ 5470.058450] ipTables: IN= OUT=eth0
SRC=192.168.1.116 DST=192.168.1.110 LEN=516 TOS=0x10 PREC=0x00 TTL=64
ID=4949 DF PROTO=TCP SPT=22 DPT=46216 WINDOW=446 RES=0x00 ACK PSH URGP=0};
while ($s =~ /(?<k> [A-Z]+) = (?<v> \S*)/xg) {
print "'$+{k}' = '$+{v}'\n";
}
C:\Temp> z
'IN' = ''
'OUT' = 'eth0'
'SRC' = '192.168.1.116'
'DST' = '192.168.1.110'
'LEN' = '516'
'TOS' = '0x10'
'PREC' = '0x00'
'TTL' = '64'
'ID' = '4949'
'PROTO' = 'TCP'
'SPT' = '22'
'DPT' = '46216'
'WINDOW' = '446'
'RES' = '0x00'
'URGP' = '0'
You can also assign the information in the log line to a hash:
my %entry = ($s =~ /(?<k> [A-Z]+) = (?<v> \S*)/xg);

In perl this should do it
#consider the $a variable has the log file my
$a = <<log file>>;
my $desired_answer;
#regex
if ($a =~ m/PROTO=(.*?) /ig)
{ $desired_answer=$1; }

thanks for all the responses!
i chose the way of shellscripting using egrep and regex...
