I downloaded from youtube the following playlist:
https://www.youtube.com/playlist?list=PLTcOKgEfeA--41UT4f6MF3LngqLpgK2HY
using youtube-dl with options specified in /etc/youtube-dl.conf which
contains the following options:
# Default configuration for youtube-dl.
-ci
-f best
-v
--sub-lang en
--convert-subs srt
--embed-subs
--fixup warn
--audio-quality 320k
because sometimes I am downloading movie videos.
So, the playlist is downloaded as:
01. Once Upon A Time... Storybook Love-fEN1CxYdQGE.mp4
02. I Will Never Love Again-UNiqBZKL3q0.mp4
03. Florin Dance-ri7q63uaKqU.mp4
04. Morning Ride-zV1nLvDMnb8.mp4
05. The Friend's Song-OFFC-aFbw88.mp4
06. The Cliffs Of Insanity-QRH-7zv46mM.mp4
07. The Swordfight-L8FGBKpIMzc.mp4
08. Guide My Sword-73PxXl-D7kE.mp4
09. The Fireswamp & The Rodents Of Unusual Size-4pD6K0sXUpY.mp4
10. Revenge-vjRDf7klEx4.mp4
11. A Happy Ending-ibB4ADNBl9M.mp4
12. Storybook Love-cxx9lRrUO_E.mp4
sans the track numbers, which I added later by changing the track name
to include the track numbers.
Now, I want to transcode them to wav format using the script:
#!/bin/bash
SHELL=/bin/bash
rm -f ERRORS *.wav
/bin/ls -1 *.mp4 | while read f; do
n=${f%mp4}wav
ffmpeg -i "$f" -ab 312k "$n"
echo "ffmpeg exited with status code $? for file $f" >> ERRORS
echo ""
if [ -f "$n" ]; then
ls -l "$n"
else
echo "$n was NOT created. Transcode failed." >> ERRORS
fi
done
ERRORS file contains
$ cat ERRORS
ffmpeg exited with status code 0 for file 01. Once Upon A Time...
Storybook Love-fEN1CxYdQGE.mp4
ffmpeg exited with status code 1 for file BZKL3q0.mp4 <<<< Notice the
failure to read file name!!!
BZKL3q0.wav was NOT created. Transcode failed. <<<< Notice the failure
to read file name!!!
ffmpeg exited with status code 0 for file 03. Florin Dance-ri7q63uaKqU.mp4
ffmpeg exited with status code 1 for file The Cliffs Of
Insanity-QRH-7zv46mM.mp4
The Cliffs Of Insanity-QRH-7zv46mM.wav was NOT created. Transcode failed.
ffmpeg exited with status code 0 for file 07. The Swordfight-L8FGBKpIMzc.mp4
and the script exits.
No output for files whose names do not even appear in the ERRORS file.
Clearly, there is a problem with the shell reading the file names from
stdin.
But I have no idea why it is failing to read '/some/' file names
Only 3 wav files created:
$ ll *wav
-rw-rw----. 1 jd jd 16515150 Dec 25 11:30 01. Once Upon A Time...
Storybook Love-fEN1CxYdQGE.wav
-rw-rw----. 1 jd jd 16347214 Dec 25 11:30 03. Florin Dance-ri7q63uaKqU.wav
-rw-rw----. 1 jd jd 28872782 Dec 25 11:30 07. The Swordfight-L8FGBKpIMzc.wav
So, could someone zero in on the script and see what I am missing?
`Cause I cannot see what's wrong.
Thanx!
JD
