Encoding from multiple input image files: Collects just around 1700 out of 17000 *.jpg

[Raphael.Becker@…]

I have: directory with about 17,000 jpg-files, 640x480 (snapshots from a still
camera).
I want: a 10 fps mpeg4 Video from is.
See also: ​http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html

Commandline: mencoder -v mf://*.jpg -mf w=640:h=480:fps=10:type=jpg -o
../mshvolcanocam_2.avi -ovc lavc -lavcopts vcodec=mpeg4

It works fine for the first ca 1700 frames (jpg). After that, the AVI gets
finished and closed. Everything works fine. AVI is not corrupt, no error
messages. Just missing thousands of frames.

I guess it it about "too many arguments" by expanding "mf://*.jpg", something
similar to the following by an internal system-call:
$ ls frames/*.jpg
bash: /bin/ls: Argument list too long
$ find frames/ -name "*.jpg" | wc -l

19692

I've recorded a transcript of mencoder, you may download it from my website:
​http://rabe.uugrn.org/temp/mplayer/mencoder.out

Again: no visible errors, just missing frames 1743 to end.

Workaround: no idea.

Thank you for reading this report.

PS: Sorry, I'm not sure about which component of mplayer is involved or
affected, so I've chosen "core". Please drop me a note and/or forward this
report to the particular recipient.

Well, mplayer works pretty fine here, no crashes. Anyway, you might be
interested in some system details as described in "Appendix B. How to report
bugs". Here we go:

Old bug, but: some JPEG files can not be decoded with ffmjpeg decoder, -vc ijpg
is supposed to help in some cases. No other ideas though.

[compn]

workaround might be mf://@filelist.txt
where filelist.txt is one image filename per line ...

[Raphael.Becker@…]

Seems to work with a newer Version.

$ find frames/2007/04/ | wc -l

mkdir -p ${MPEG_DIR}
for MM in 01 02 03 04; do

mencoder "mf://frames/${YYYY}/${MM}/${YYYY}${MM}*.jpg" ${OPTS} -o ${MPEG_DIR}/${YYYY}-${MM}.mpeg

done

Bug may be closed, works for me now.
