This code is intended for errors in external libraries
when no corresponding error code can be found.
AVERROR_UNKNOWN is too vague for that and looks like AVERROR_BUG.
|
|
Some API require a buffer and return a specific error
if it is too small. This error code helps to map codes.
|
|
These functions are modeled after the corresponding utilities in
libavutil/timestamp.h.
|
|
The value returned by strerror_r may be positive depending on the system,
so it is necessary to use AVERROR() in order to get a negative
number. This way the successive negative check will not fail, and the
function will print a meaningful error message on the buffer.
|
|
The table is mostly useful to enumerate the available AVERROR* in the
test output.
|
|
This should fix the parseutils fate test.

Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

It should be used to mark codepath that can be reached only through
programming error.

AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and
has a too much specific meaning, which is better explained through a
log message. Thus it can be replaced by AVERROR(EINVAL).
This breaks API.

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

This is different from AVERROR(EINTR) because calls that fail with EINTR
should usually be restarted.

This avoids the need for the application to fill the string in case
