Re: [FFmpeg-user] ffmpeg script
Thanks Steve, you have been superhelpful.
the find statement works well, it scans looking for .ts files just like I
wanted.
I am using the find.sh script you developed to call a seperate script to
run ffmpeg and then pull closed caption.
it seems to be working well right now.
will work on removing those .ts files later on.
i consider this solved and appreciate the help

Found problem: you basically call
if ffmpeg -i ... Output_file_name "Output_file_name.ts.mp4"
line should read:
if ffmpeg -y -i "$1" -vf scale=-1:720 -c:v libx264 -crf 23 -preset
ultrafast -c:a copy "$(basename "$1" .ts).mp4";
So FFmpeg is like "I dunno what kinda output you want me to use!"

Re: [FFmpeg-user] ffmpeg script
Hi Steve,
so i created 2 scripts:
find.sh
#! /bin/bash
find ~/Plex-Drives/TV/TV/ -iname '*.ts' -type f -execdir
~/Plex-Drives/TV/TV/script.sh "{}" \;
script.sh
#!/bin/bash
if [ ! -e lock ];
then touch lock;
if ffmpeg -y -i "$1" -vf scale=-1:720 -c:v libx264 -crf 23 -preset
ultrafast -c:a copy $(basename "$1" .ts) "$1.mp4";
then
ccextractor "$1" -o "$(basename "$1" .ts).srt"
#rm "$1";
fi
fi
when i run it i think it breaks something as the script stops running and
goes back to the command prompt or its equivalent in a linux terminal.
I am stumped. any ideas

Heads up - you're mixing $1 (argument 1) with $i (variable i). Should all
be $1 if you were having the find command above find, execute the script
and pass the filename as the argument.

Re: [FFmpeg-user] ffmpeg script
thanks, appreciate the help Steve:
I am at work at present and will try your suggestions when i get home
tonight; however, does this seem to make sense.
Two scripts 1) has the ' *find -iname '*.ts' -type f -execdir
/path/to/script.sh "{}" \;*' data and calls script.sh.
2) script.sh
can i modify script.sh to include multiple '*then*' statements?
e.g.
script.sh
#! /bin/bash
if [ ! -e lock ];
then touch lock;
if ffmpeg -y -i "$1" -vf scale=-1:720 -c:v libx264 -crf 23 -preset
ultrafast -c:a copy $(basename "$i" .ts) "$i.mp4";
*then*
* ccextractor "$x" -o "$y".srt *
then
rm "$1";
fi
is this likely to be a solution that will scan entire multimedia hdd (if i
put in correct path by find statement) and then ffmpeg the .ts to .mp4 then
extract closed caption info, then remove the .ts files?

I am currently using HD Homerun which downloads ,TS files or transport

my solution to date is to shrink the .ts file using ffmpeg and then extract
the subtitle using ccextract.
at present I run a bash script in each folder containing .ts files, but
would like one I can run from the main directory that would look in all sub
directories find .ts files remux them to mp4, extract the closed caption
stream to .srt and then remove the .ts files.
so far i have the following script. Steven Penny from Stack Exchange
contributed code and i added in the ffmpeg and ccextract lines:

for x in *.ts
do
y=$(basename "$x" .ts)
ffmpeg -i "$x" -vf scale=-1:720 -c:v libx264 -crf 23 -preset ultrafast
-c:a copy "$y".mp4
ccextractor "$x" -o "$y".srt
done
This works well if I run it in a directory. I would like to add to it
though and maybe have something like a
Find . -name *.ts
statement or some way for it to look in all folders on multimedia hdd for
.ts files and then do the For Loop but am unsure how.
Couple of suggestions:
1) tweak the script so it takes in an argument - the .ts file name that
does the FFmpeg command and other programs. Generalize it.
2) instead of doing a for loop, do a "find . -iname '*.ts' -type f -execdir
scriptname {} \+"
This will find all filenames that end (case insensitive) with .ts, and
execute your script on it.
I also want to add something like
rm /s *.ts
but am unsure if this will work or where to add it after the For Loop.
Would it need a [wait] statement after [done] on the last line.
Another suggestion I've used in the past is FFmpeg returns 0 if
successfully. In the script, have the if statement it checks be the FFmpeg
command. If no problem, it returns 0 (if I recall correctly). Check this
value and delete if you want. Give me a bit and I have an automatic DVD
creation script I can copy and paste a section from.
any advice on writing a bash script that would search for .ts files,
convert them to mp4, and then remove the .ts files would be greatly
appreciated.
