The implementation follows the same logic that .NET is using internally, with the only exception that it doesn't expand short path components in 8.3 format. .NET does this as the same function is also used for other purposes, but in our case, that's not required. Short (8.3) paths are working as well with the extended path prefix, even when longer than 260. Successfully tested: * Regular paths wth drive letter * Regular UNC paths * Long paths wth drive letter * Long paths wth drive letter and forward slashes * Long UNC paths * Prefixed paths wth drive letter * Prefixed UNC paths I have kept the individual functions separate on purpose, to make it easy to compare with the .NET impl. (compilers should inlinie those anyway) v2 * wchar_filename: Improve comments and function documentation * os_support: adjust defines to use win32_stat v3 * removed length check in path_is_extended() * added path_is_device_path() check in add_extended_prefix() * add_extended_prefix(): clarified doc and add checks * clarified string allocation length calculation * replaced 260 with MAX_PATH * removed redundant checks after normalization v4 * rebased. no changes softworkz (2): avutil/wchar_filename,file_open: Support long file names on Windows avformat/os_support: Support long file names on Windows libavformat/os_support.h | 26 ++++-- libavutil/file_open.c | 2 +- libavutil/wchar_filename.h | 166 +++++++++++++++++++++++++++++++++++++ 3 files changed, 188 insertions(+), 6 deletions(-) base-commit: 6076dbcb55d0c9b6693d1acad12a63f7268301aa Published-As: https://github.com/ffstaging/FFmpeg/releases/tag/pr-ffstaging-28%2Fsoftworkz%2Fsubmit_long_filenames-v4 Fetch-It-Via: git fetch https://github.com/ffstaging/FFmpeg pr-ffstaging-28/softworkz/submit_long_filenames-v4 Pull-Request: https://github.com/ffstaging/FFmpeg/pull/28 Range-diff vs v3: 1: ce70f7b021 = 1: 13118dc1fa avutil/wchar_filename,file_open: Support long file names on Windows 2: a5268800a4 = 2: 252ed89499 avformat/os_support: Support long file names on Windows -- ffmpeg-codebot _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
