* avformat/async,cache: Use more unique context namesAndreas Rheinhardt2024-05-251-9/+9
| | | | | | | | Otherwise Doxygen thinks any text like "Context for foo" is a link to the async protocol's struct called "Context". Reported-by: Andrew Sayers <ffmpeg-devel@pileofstuff.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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.
* all: Don't set AVClass.item_name to its default valueAndreas Rheinhardt2023-12-221-1/+0
| | | | | | | | Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9; also avoids relocations. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/internal: Move avpriv-file API to a header of its ownAndreas Rheinhardt2022-09-031-2/+2
| | | | | | | It is not used by the large majority of files that include lavu/internal.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Replace ffurl_close() by ffurl_closep() where appropriateAndreas Rheinhardt2020-05-251-1/+1
| | | | | | | | | | It avoids leaving dangling pointers behind in memory. Also remove redundant checks for whether the URLContext to be closed is already NULL. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avformat/cache - delete cache file after closing handleGyan Doshi2019-05-251-2/+15
| | | | Verified that cache files get deleted on Windows.
* libavformat: not treat 0 as EOFDaniel Kucera2017-10-191-2/+2
| | | | | | | | | | transfer_func variable passed to retry_transfer_wrapper are h->prot->url_read and h->prot->url_write functions. These need to return EOF or other error properly. In case of returning >= 0, url_read/url_write is retried until error is returned. Signed-off-by: Daniel Kucera <daniel.kucera@gmail.com>

* avformat/cache: Avoid int-overflow in cache compare functionBryan Huh2015-11-091-1/+1
| | | | | | | | | | | cache protocol indexes its cache using AVTreeNodes which require a cmp function for inserting and searching new cache-entries. This cmp function expects a 32-bit int return value (negative, zero, or positive) but the cache cmp function returns an int64_t which can overflow the int, giving negative numbers for when it should be positive, vice versa. This manifests itself only for very large files (e.g. 4GB+) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avformat/cache: Use int64_t to avoid int overflow in cache_readBryan Huh2015-11-041-1/+1
| | | | | | | | | | | | Fixes an issue where an int64_t ffurl_seek return-value was being stored in an int (32-bit) "r" variable, leading to integer overflow when seeking into a large file (>2GB), and ultimately a "Failed to perform internal seek" error mesage. To test, try running `ffprobe 'cache:http://<something>'` on a file that is ~3GB large, whose moov atom is at the end of the file Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avutil/tree: add additional const qualifier to the comparatorGanesh Ajjanagadde2015-10-241-2/+2
| | | | | | | | | | | | | libc's qsort comparator has a const qualifier on both arguments. This adds a missing const qualifier to exactly match the comparator API. Existing usages of av_tree_find, av_tree_insert are appropriately modified: type signature changes of the comparators, and removal of unnecessary void * casts of function pointers.
