* avutil/file: fix av_file_map file mapping on WindowsKacper Michajłow2024-12-151-1/+1
| | | | | | | | | | | | | This makes the behavior of av_file_map() the same on Windows as it is on other platforms. The file is opened as read-only, but the mapping is copy-on-write, allowing the user to write to the memory pages returned by av_file_map(). This commit fixes libavutil\tests\file.c test, which would crash when trying to write to a read-only memory page.

* avutil/file: use av_err2str to simplify codeMarvin Scholz2024-09-131-7/+3
| | | | | No need to explicitly specify the buffer here as it is only ever passed to av_log, so av_err2str can be used.

* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+1
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

* avutil/file: Properly deprecate av_tempfile()Andreas Rheinhardt2022-09-031-0/+2
| | | | | | | | | | It has been deprecated in b4f59beeb4c2171879d0d7607a4a7d6165f07791, but the attribute_deprecated was not set and there was no entry in APIchanges. This commit adds these and schedules it for removal. Given that the reason behind the deprecation is exactly the same as in av_fopen_utf8(), reuse its FF_API_AV_FOPEN_UTF8.

| | | | | | | | | | | | | | | | | | | | | | | | | | When libavformat was changed to use the new avpriv_open function in 51eb213d001, this silently bypassed the existing wrapper for win32. Move the win32 wrapper into libavutil/file.c to make sure it gets called everywhere (not just in the libavformat case). This makes sure that non-ascii file names gets opened properly (where file names internally are stored as utf8, but they get converted to wchar_t and opened with _wsopen).
