Okay, so you are absolutely sure each an every one of those files
listed exists at their newl given names?
Yes!!! Emphatically YES!! Checked dozens of times.
while read f; do
N=`basename "$f" | sed -e 's/mkv//' -e 's/mp4//' -e 's/webm//'`
BTW, what happens if the YouTube magic hash contains "mp4"
(e.g. "X6gmp4rTl")?
(Solution: 's/\.mp4$//'.)
Yes - that is in my script: vis a vis
-e 's/mp4//
as my sed command has 3 expressions using the -e option.
/bin/ffmpeg -i "$f" -map 0:a -c:a libmp3lame -ab 320k -ac 2 -y
$D/$N"mp3"
Replace this quoted line with
echo "****** $f ******"
just to go sure that the absolutely correct filenames are found.
To go one further: Replace the quoted line with
[ -f "$f" ] || echo "Not found: ***** $f *****"
to prove that the shell can find these files as listed in your
VIDEO_FILES. If not, then ffmpeg can't find it either.
ffmpeg gets the filename option as an arbitrary option from the
operating system. If other programs can successfully make use of it, so
can ffmpeg.
And I am still getting parse errors, because ffmpeg is UNABLE to parse
long filenames.
No magic involved, ffmpeg does nothing special.
What makes it even more confusing, the parse error message appears
within or between the console output
of transcoding a previous file.
That's the letters flying in, interactively controlling ffmpeg's output
options.
done < VIDEO_FILES > FFMPEG_ERRORS 2>&1
I don't know why, but I have seen it before, and the '< VIDEO_FILES'
may be flooding ffmpeg's stdin. Do try "-nostdin".
I think ffmpeg just does not know how to read stdin rightly, or perhaps
the shell is not providing carriage returns or "newline"
at end of each line.
However, here are the mods:
#!/bin/bash
>FFMPEG_ERRORS
while read f; do
N=`basename "$f" | sed -e 's/mkv//' -e 's/mp4//' -e 's/webm//'`
[ -f "$f" ] || echo "Not found: ***** $f *****"
done < VIDEO_FILES 2>&1 | tee FFMPEG_ERRORS
and did NOT get any Not found !!!!
