* avformat/file: guard fd_dup by FD_PROTOCOL or PIPE_PROTOCOLZhao Zhili2024-07-161-0/+2
| | | | | | | fd_dup is unused when fd and pipe have been disabled. This also fix build error with wasi since 'dup' isn't available. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>
* Revert "avformat/file: seek back to initial position for fd protocol"Rémi Denis-Courmont2024-05-301-13/+1
| | | | | | | | | | | | The generally expected behaviour is for software to append from the current position, not to keep resetting. See also how shell works: # (foo && bar) > file ...would normally concatenate the output of both commands to file. If foo seeks like lavf, bar would instead overwrite the output of foo (possibly not completely). This reverts commit 5c3d2177e7be7dde69a83b1b394f57976c164c84.
* avformat/file: fail for non-numerical arguments to pipe:Marton Balint2024-05-071-2/+5
| | | | | | | | | | | | | | | | | | | | | | Before this patch, the implementation of pipe: inputs/outputs would silently fall back to stdin/stdout for any argument not successfully parsed by strtol(). This patch introduces an explicit error for any non-numerical arguments, which should avoid user confusion as in #10977. New behavior: $ cat /tmp/video.mkv | ./ffmpeg -i pipe:aa -acodec copy -vcodec copy -f matroska pipe:1 | cat >/tmp/out.mkv [pipe @ 0x5618c7bcf740] Non-numerical argument "aa" to pipe: [in#0 @ 0x5618c7bced00] Error opening input: Invalid argument Error opening input file pipe:aa. Error opening input files: Invalid argument Based on the patch of Nils Goroll <nils.goroll@uplex.de>. Signed-off-by: Marton Balint <cus@passwd.hu>
* avcodec, avformat/ffjni: fix duplicate JNI symbolsLeo Izen2024-04-041-1/+1
| | | | | | | | | Use SHLIBOBJS and STLIBOBJS in the Makefiles for avcodec and avformat, and add a stub ffjni.c to libavformat, which allows the symbols to be duplicated for shared builds but not static builds.

* 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>
* avformat/file: Combine all CONFIG_ANDROID_CONTENT_PROTOCOL blocksAndreas Rheinhardt2024-03-261-21/+15
| | | | | | | | | | | | Besides improving readability this also ensures that a developer who has the android content protocol enabled and works on the other parts of the file will not forget to add necessary inclusions just because of (indirect) inclusions from the files included only when said protocol is enabled.

* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+3
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

| | | | | | | | | | | | | | | | | | | | Instead of a linked list constructed at av_register_all(), store them in a constant array of pointers. Since no registration is necessary now, this removes some global state from lavf. This will also allow the urlprotocol layer caller to limit the available protocols in a simple and flexible way in the following commits.

| | | | | | | | | | | | | | | | | | | | | | | | | | Interruptibility of file operations is strongly desirable in case of slow storage access, e.g. mounted network share. This commit introduces possibility to limit data quantity transferred by 'file' protocol at once. By default, old behaviour is preserved and data is still tried to be transferred without block size limitation. Note that file I/O operation still may block (or even freeze) inside of single read(2) or write(2) operation. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
