I'm trying to run the below command in a script and it seems it's not adding any text layout to the video, I'm sure I didn't it before and it was fine.
My question is, do I need to set up X11 environment in order to use dynamictext or text filters?
Thanks in advance.
/usr/bin/melt \
"/var/www/html/test/nkLcBPkebo/t-1.mp4" \
-audio-track \
"/var/www/html/test/nkLcBPkebo/t-1_sound.mp4" \
-attach-track \
"text:This is my best video" \

I think I found the issue! it's was all about the order of the parameters :)
Having the text right after the video (before the audio) should fix it

When I apply a -filter crop parameter to my melt script, it only seems to crop each clip - not the -mix mixing between clips.
melt \
clip1.mp4 in=180 out=360 \
-mix 20 -mixer luma -mixer mix:-1 \
clip2.mp4 in=660 out=960 \
-mix 20 -mixer luma -mixer mix:-1 \
clip3.mp4 in=1080 out=1300 \
-filter crop left=420 right=420 \
-consumer avformat:"output.mp4" ab=128k crf=23 -profile "./square_profile.txt"
Is there some other way I can apply a crop that works with -mix transitions?
Solving my own problem:
The solution is to add a crop for each file, using -attach instead of -filter
melt \
clip1.mp4 in=180 out=360 \
-attach crop left=420 right=420 \
-mix 20 -mixer luma -mixer mix:-1 \
clip2.mp4 in=660 out=960 \
-attach crop left=420 right=420 \
-mix 20 -mixer luma -mixer mix:-1 \
clip3.mp4 in=1080 out=1300 \
-attach crop left=420 right=420 \
-consumer avformat:"output.mp4" ab=128k crf=23 -profile "./square_profile.txt"
I would like to create a string of index and value pairs. This is to be used in dialog menu.
declare -r -a arr=(
piano
table
chair
)
dialog \
--backtitle "Launcher" \
--title "App" \
--ok-label 'Select' \
--cancel-label "Back" \
--menu "Select an application" \
$dialog_height $dialog_width 4 \
"1" "piano" \
"2" "table" \
"3" "chair"
So I'm looking to have the:
"1" "piano" \
"2" "table" \
"3" "chair"
generated automatically from array.
There's a similar question pass an array to dialog menu I tried what's there I couldn't get it to work for me.
To auto-generate the tags 1, 2, 3 in front of every array entry, use
items=(piano table chair)
taggedItems=()
for ((i=1; i<="${#items[#]}"; ++i)); do
taggedItems+=("$i" "${items[i-1]}")
done
# then use "${taggedItems[#]}"
Opposed to your linked awk solution, this works with arbitrary items that may contain spaces, special symbols like * and even linebreaks.
declare -a arr=(
''
piano
table
chair
)
unset 'arr[0]'
declare -ar arr
# Remove the echo below once ready for the fun.
echo dialog \
--backtitle "Launcher" \
--title "App" \
--ok-label 'Select' \
--cancel-label "Back" \
--menu "Select an application" \
$dialog_height $dialog_width 4 \
$(for i in "${!arr[#]}"; do echo "$i" "${arr[i]}"; done)
OPTIONS=(1 "table"
2 "piano"
3 "......")
dialog \
--backtitle "Launcher" \
--title "App" \
--ok-label 'Select' \
--cancel-label "Back" \
--menu "Select an application" \
$dialog_height $dialog_width 4 \
"${OPTIONS[#]}" \
2>&1 >/dev/tty
There are two ways, using simple array:
#!/bin/bash
declare -r -a arr=(
piano
table
chair
)
options=$(printf '%s\n' "${arr[#]}" | awk '{print v++,$arr}')
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
$options \
2>&1 >/dev/tty
Or with associative array:
#!/bin/bash
declare -r -A arr=(
piano
table
chair
)
options=$(printf '%s\n' "${!arr[#]}" | awk '{print v++,$arr}')
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
$options \
2>&1 >/dev/tty
To start menu numbers at 1:
#!/bin/bash
declare -r -a arr=(
piano
table
chair
)
options=$(printf '%s\n' "${arr[#]}" | awk -v v=1 '{print v++,$arr}')
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
$options \
2>&1 >/dev/tty
To use both key and value of associative array in menu:
#!/bin/bash
declare -r -A arr=(
[piano]=piano
[table]=mesa
[chair]=cadeira
)
options=$(printf "%s\n" "${!arr[#]} " "${arr[#]}")
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
$options \
2>&1 >/dev/tty
Correct answer works both with normal and associative arrays of entries, using numerical index or associative key as menu key:
Normal array of menu entries, using numerical index as menu key:
#!/usr/bin/env bash
arr=(
piano
table
chair
)
options=()
for k in "${!arr[#]}"; do
options+=( "$k" "${arr[$k]}" )
done
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
"${options[#]}" \
>/dev/tty 2>&1
Full example with associative array:
#!/usr/bin/env bash
declare -A assoc=(
[p]=piano
[t]=table
[c]=chair
)
options=()
for k in "${!assoc[#]}"; do
options+=("$k" "${assoc[$k]}")
done
choice="$(
dialog \
--backtitle "Test" \
--title "Test" \
--menu "Test" \
0 0 4 \
"${options[#]}" \
2>&1 >/dev/tty
)"
clear
case $choice in
t)
printf %s\\n "Let's set the table."
;;
p)
printf %s\\n "Let's play piano."
;;
c)
printf %s\\n "Let's sit dow."
;;
*)
printf %s\\n "Let's decide later."
;;

I'm trying to load the query result from one table to another. It connects fine and execute a query to get the metadata but no data is returned.
from pyspark.sql import SQLContext, Row, SparkSession
spark = SparkSession.builder.config("spark.driver.extraClassPath", "C:\\spark\SQL\\sqljdbc_7.0\\enu\\mssql-jdbc-7.0.0.jre10.jar").getOrCreate()
SQL = "Select [InvoiceID],[CustomerID],[BillToCustomerID],[OrderID],[DeliveryMethodID],[ContactPersonID],[AccountsPersonID],[SalespersonPersonID],[PackedByPersonID],[InvoiceDate],[CustomerPurchaseOrderNumber],[IsCreditNote],[CreditNoteReason],[Comments],[DeliveryInstructions],[InternalComments],[TotalDryItems],[TotalChillerItems],[DeliveryRun],[RunPosition],[ReturnedDeliveryData],[ConfirmedDeliveryTime],[ConfirmedReceivedBy],[LastEditedBy],[LastEditedWhen] FROM [Sales].[Invoices]"
pgDF = spark.read \
.format("jdbc") \
.option("url", "jdbc:sqlserver://Localhost") \
.option("query", SQL) \
.option("user", "dp_admin") \
.option("Database", "WideWorldImporters") \
.option("password", "password") \
.option("fetchsize", 1000) \
.load(SQL)
pgDF.write \

.option("dbtable", "wwi.Sales_InvoiceLines") \
.option("user", "dp_admin") \
.option("Database", "DW_Staging") \
.option("password", "password") \
.option("mode", "overwrite")
Looking at the sql server profiler :
exec sp_executesql N'SELECT * FROM (Select [InvoiceID],[CustomerID],[BillToCustomerID],[OrderID],[DeliveryMethodID],[ContactPersonID],[AccountsPersonID],[SalespersonPersonID],[PackedByPersonID],[InvoiceDate],[CustomerPurchaseOrderNumber],[IsCreditNote],[CreditNoteReason],[Comments],[DeliveryInstructions],[InternalComments],[TotalDryItems],[TotalChillerItems],[DeliveryRun],[RunPosition],[ReturnedDeliveryData],[ConfirmedDeliveryTime],[ConfirmedReceivedBy],[LastEditedBy],[LastEditedWhen] FROM [Sales].[Invoices]) __SPARK_GEN_JDBC_SUBQUERY_NAME_0 WHERE 1=0'
the where 1= 0 gets added and no data is returned, why and how to remove it?

I'm trying to build this image bitbake rpi-hwup-image
the problem is with qtbase, it fails with this error:
| ERROR: Feature 'opengl-desktop' was enabled, but the pre-condition '(config.win32 && !config.winrt && !features.opengles2 && (config.msvc || libs.opengl))
| || (!config.watchos && !config.win32 && libs.opengl)' failed.
|
| ERROR: The OpenGL functionality tests failed!
| You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
| QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.
Update
This problem is solved by uncommenting PACKAGECONFIG_append_qtbase and it has a typo so, it's been updated to be PACKAGECONFIG_append_pn-qtbase.
I added those lines too:
PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl".
I comment out this line LICENSE_FLAGS_WHITELIST = "commercial".
but it fails again at qtbase build by this error (this is the tail of the log file) (I deleted the tmp folder and started bitbake rpi-hwup-image again but it went to the same error)

I found the solution according to this page.
The configuration part -at this page- says something about ommiting the tests part at this option -nomake tests, it's the same part that fails at the compiling stage of qtbase.
so after cleaning qtbase and adding this part to my local.conf
PACKAGECONFIG_remove_pn-qtbase = " tests gl"
gl is omitted too because we want to build qtbase for eglfs not for desktop.
I have a shell script in C which is defined as
#define SHELLSCRIPT "\
sed 's/./& \
inserted text \
/20' fileA.txt > fileB.txt \
"
When this shell script is run on terminal, it inserts the text inserted text in fileB.txt at offset 20. Now, I want this 20 fileA.txt and fileB.txt to be fetched from a variable.
How should I do that? I tried the following
#define SHELLSCRIPT "\
sed 's/./& \
inserted text \
/$i' fileA.txt > fileB.txt \
"
and in C before I run the above shell script, I run system("i=20"); but then I get this error below
sed: 1: "s/./& this comment has ...": bad flag in substitute command: '$'
How can I achieve this?
When you run system(), it starts up a fresh shell each time. So the shell that i=20 runs in is not the same shell that the sed command runs in.
Instead of $i in the script text, put %d there instead. Then you can use it as a format string to sprintf which can format the command into a separate variable.
#define SHELLSCRIPT "\
sed 's/./& \
inserted text \
/%d' fileA.txt > fileB.txt \
"
char command[500];
sprintf(command, SHELLSCRIPT, 20);
system(command);
how about you replace your script command
#define SHELLSCRIPT "\
sed 's/./& \
inserted text \
/%d' %s > %s \
"
and then you replace by your variables, before executing the command:
char cmd[100 +1];
sprintf(cmd, SHELLSCRIPT , 20, "file1", "file2");
system(cmd)
