Bugzilla Bug 137530

mjpegtools-1.8.0-r1 installed

Having problems using the lav2mpeg script from mjpegtools-1.8.0-r1 to convert
dv quicktime files captured from a dv camera to vcd compliant mpeg files
whenever i use a command line switch like -m to set the encoding mode. I get
the following error:

bobert@it7 /tmp/lav $ lav2mpeg -m vcd_high dvgrab-001.mov
/usr/bin/lav2mpeg: line 256: shift: 3-1: numeric argument required
08:03:09 -  mode=vcd_high -
**ERROR: [lavinfo] Error opening -m: No such file or directory
08:03:09 - 'lavinfo -m vcd_high dvgrab-001.mov' died! exiting
08:03:09 -  maybe you don't have lavinfo. or your input flags were wrong
08:03:09 -  input files must be the last input on the command line

Workaround change line 256 in /usr/bin/lav2mpeg from

shift `expr $MOPTIND-1`

to 

shift $(($MOPTIND-1))

Hope this helps.

The problem here seems to be that lav2mpeg starts lavinfo and just uses bash's
eval on the returned info. 
# eval $($LAVINFO $@ | grep "=")

But lavinfo returnes lines like this:
video_inter=***BOGUS/UNKNOWN*** interlacing

That means that at least all spaces in the output must be quoted like this:
# eval $($LAVINFO $@ | grep "=" | sed -e 's: :\\ :g')

But the problem continues than as that value is compared against "1" later on:
# if [ $video_inter -eq 1 ]; then

Perhaps changing to
# if [[ ${video_inter/interlacing} != ${video_inter} ]]; then
helps.

Applied changes to mjpegtools-1.8.0-r2, hopefully it works that way now.

I also consider this bug not resolved.

zzam, whats the status on this one?

beandog, I have not used this after last time touching this, so I have no idea
about the status.

obsolete bug. 1.9.0 is stable on all arch's. no up to date information
provided, closing as TEST-REQUEST.
