That is, unless the caller explicitly asks for them.
Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.
This actually matches what av_get_double did earlier, the
0.0/0.0 division was intentional, for producing NAN.
Still keeping the check for the return value from
av_get_number, for clarity.

This avoids doing a division by zero if the option wasn't found,
or wasn't an option of an appropriate type.

The new error code is better than AVERROR(ENOENT), which has a
completely different semantics ("No such file or directory").

eval API.
More grep-friendly and more consistent with the rest of the FFmpeg
API.

containing an error code.
Allow these functions to convey the reason of the failure to the
calling function, failure which is not always due to a parsing error
but it may depend for example on a memory problem.
Also fix several potential memleaks.

ff_parse_and_eval_expr(), place the names for constants/functions
before the corresponding values.
This looks more readable, as the user is expected to know the names
before the values.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Original commit message:
Very evil missuse of svn to test if AVOption and AVOption2 are compatible.
If this test triggers anywhere for anyone, revert this commit immedeatly.
Ill revert this in a day or 2, its just so we know beforehand if the idea
with the union is doable or not without breaking ABI/API.

Make av_set_string3() print a message in case of unknown option.
This change led to multiple identical error messages to be printed if an option
was not found.

av_set_string() and av_set_string2(), they will be dropped at the next

value failure.
Originally committed as revision 16156 to svn://svn.ffmpeg.org/ffmpeg/trunk
av_set_string() and av_set_string2() do not accept as parameter the
name of a named constant.
This avoids av_set_string2() and av_set_string() to misbehave when
there is an option and a named constant with the same name.
See the thread: "[PATCH] Remove libavcodec/opt.c:set_all_opt()".
