Hi,

This looks like an easy target to fix. Can someone have a look at
this? Is this critical and applicable for earlier releases as well?

Best,
Reinhard

"Unable to parse option value "scan_offset""

Package: libav-tools
Version: 6:11-2
Severity: normal
Tags: upstream

Dear Maintainer,

avconv -i in.mp4 -target pal-svcd out.mpg

fails with:
[mpeg2video @ 0x14b63c0] [Eval @ 0x7ffff3fcfd50] Undefined constant or missing
'(' in 'scan_offset'
[mpeg2video @ 0x14b63c0] Unable to parse option value "scan_offset"
[mpeg2video @ 0x14b63c0] Error setting option flags to value +scan_offset.
....
Error while opening encoder for output stream #0:0 - maybe incorrect parameters
such as bit_rate, rate, width or height

After fixing avconv_opt.c:

         opt_default(NULL, "b:a", "224000");

avconv works as expected. Is it possible that patch
https://patches.libav.org/patch/19539/ got lost?
