Anton Khirnov	99684f3ae7	avio: add a destructor for AVIOContext Before this commit, AVIOContext is to be freed with a plain av_free(), which prevents us from adding any deeper structure to it.	8 years ago
Luca Barbato	3f75e5116b	avio: Keep track of the amount of data written Make avio_size() work with any write AVIOContext.	8 years ago
Anton Khirnov	8ea35af762	avio: add a new flag for marking streams seekable by timestamp	8 years ago
Anton Khirnov	75c1db6152	avio: cosmetics, prettify AVIO_SEEKABLE_NORMAL Move the doxy above the definition, change the value itself to the (1 << n) pattern, which is more readable for flags.	8 years ago
Martin Storsjö	db7968bff4	avio: Allow custom IO users to get labels for the output bytestream This allows callers with avio write callbacks to get the bytestream positions that correspond to keyframes, suitable for live streaming. In the simplest form, a caller could expect that a header is written to the bytestream during the avformat_write_header, and the data output to the avio context during e.g. av_write_frame corresponds exactly to the current packet passed in. When combined with av_interleaved_write_frame, and with muxers that do buffering (most muxers that do some sort of fragmenting or clustering), the mapping from input data to bytestream positions is nontrivial. This allows callers to get directly information about what part of the bytestream is what, without having to resort to assumptions about the muxer behaviour. One keyframe/fragment/block can still be split into multiple (if they are larger than the aviocontext buffer), which would call the callback with e.g. AVIO_DATA_MARKER_SYNC_POINT, followed by AVIO_DATA_MARKER_UNKNOWN for the second time it is called with the following data.

Martin Storsjö	e9443105ea	avio: Remove a leftover comment The declarations that this comment referred to were removed in `2439f2ca8` - there is no unbuffered IO in this header now. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago

Luca Barbato	252d6200c3	avio: Add avio_put_str16be	10 years ago
Diego Biurrun	4d7ab5cfeb	doxygen: Add a number of missing function parameter descriptions	11 years ago
Luca Barbato	b522000e9b	avio: introduce avio_closep	12 years ago
Dale Curtis	0575772fa0	avformat: Identify anonymous AVIO typedef structs. Anonymous typedef structs prevent forward declaration, this change gives the AVIOContext and AVIOInterruptCB structures a name. These structures are now in line with other common structures such as AVFormatContext and AVCodecContext. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Stefano Sabatini	5d1203f063	avio: flush the internal buffer in avio_close() This is consistent with stdio, and thus what people would naturally expect.	12 years ago
Mans Rullgard	6208313aeb	avio: make AVIOContext.av_class pointer to const Fix this warning: libavformat/aviobuf.c:663:20: warning: assignment discards qualifiers from pointer target type Although this is a public header, it should remain source and binary compatible. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	374e469b8d	lavf: remove disabled FF_API_OLD_INTERRUPT_CB cruft	13 years ago
Anton Khirnov	2439f2ca82	lavf: remove disabled FF_API_OLD_AVIO cruft	13 years ago
Martin Storsjö	6b9e4eea83	avio: Fix the value of the deprecated URL_FLAG_NONBLOCK This isn't used in practice anywhere within libav at the moment, but change it for consistency until it is removed. URL_RDONLY/WRONLY were fixed in commit `5b81e29593` (after the values that actually were used were changed at the major bump, in commit `cbea3ac8`), but this flag was unintentionally left unfixed. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	32b83aeec1	avio: Add an URLProtocol flag for indicating that a protocol uses network This definition is in two files, since the definitions will move to the private header at the next bump. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	eca06cbed9	lavf doxy: add installed headers to groups.	13 years ago
Anton Khirnov	fb42db7c39	lavf doxy: add avio groups into the lavf_io group.	13 years ago
Martin Storsjö	45f511ece7	avio: Mark the old interrupt callback mechanism as deprecated Prepare for removing it at an upcoming major bump.	13 years ago
Martin Storsjö	1dee0aca74	avio: add avio_open2, taking an interrupt callback and options The interrupt callback has to be passed in during opening (setting it after opening isn't enough), since a blocking open couldn't be interrupted otherwise. Options are passed down to procotols and also need to be available during open() in most cases. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Martin Storsjö	6aa0b98fb2	avio: Add AVIOInterruptCB This is a better io interrupt callback function, which has an opaque parameter, which is given to the interrupt callback. This allows callers to precisely cancel IO for one single AVFormatContext, without interrupt other ones in the same process. Note, it's not needed in AVIOContext, at the moment.

Reinhard Tartler	21a19b7912	doxygen: Prefer member groups over grouping into modules Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.	14 years ago
Martin Storsjö	9abbe8cc13	Use av_printf_format to check the usage of printf style functions This helps catching cases where the format string doesn't match what is passed in, or injection bugs where user data is passed in as format string. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Can Wu	d49051e074	avio: document buffer must created with av_malloc() and friends Else a later buffer resize in ffio_set_buf_size() will ABORT. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Martin Storsjö	5b81e29593	avio: Fix the deprecated fallback URL-prefixed open flags While deprecated, they're totally useless as long as their values are different from the AVIO_FLAG values that are used internally. Currently, this leads to old libav applications still compiling correctly (since we haven't removed the fallback wrappers), but failing since the functions internally compare to the new AVIO_FLAG values. These should be removed at some point, but they aren't removed yet. The intent is to be able to recompile an old application against the new ABI without modifying the code, and this doesn't work currently. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Stefano Sabatini	59d96941f0	avio: remove AVIO_* access symbols in favor of new AVIO_FLAG_* symbols Make AVIO_FLAG_ access constants work as flags, and in particular fix the behavior of functions (such as avio_check()) which expect them to be flags rather than modes. This breaks API.	14 years ago

Anton Khirnov	4bde56d1af	avio: deprecate url_exist in favor of avio_check.	14 years ago
Stefano Sabatini	175389c854	avio: add avio_check() The new function is more flexible than url_exist(), as it allows to specify which access flags to check, and does not require an explicit open of the checked resource. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Anton Khirnov	cbea3ac820	avio: left-shift AVIO_ flags on next bump Now AVIO_RDONLY is defined as 0, so it's not usable as a flag.	14 years ago
