Martin Storsjö	3627ce2f1d	aviobuf: Add functions for null buffers Null buffers are useful for simulating writing to a real buffer for the sake of measuring how many bytes are written. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Alexandra Khirnova	5626f994f2	avformat: Use av_reallocp() where suitable Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Ben Avison	5afe1d2791	avio: Add const qualifiers to ffio_read_indirect This provides at least some protection against potential accidental corruption of AVIO buffer workspace. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	daf1e0d3de	avio: Add an internal function for reading without copying As long as there is enough contiguous data in the avio buffer, just return a pointer to it instead of copying it to the caller provided buffer. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Hendrik Schreiber	b512360184	avio: Don't set the seekable flag if no seek function is provided Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Hendrik Schreiber	650355089c	avformat/aviobuf/ffio_init_context: set seekable automatically Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	186ec17843	avformat/aviobuf: Add ffio_ensure_seekback() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	2ca48e4666	avformat: Append data in fill_buffer() when possible Data is appended in fill_buffer() when there is sufficient space left and the data pointer only reset when needed. Previously the data pointer was more often reset, loosing more seekback space than otherwise needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	ad6a50c0ed	avformat: add writeout_count statistic Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	53c25ee073	aviobuf: Discard old buffered, previously read data in ffio_read_partial This makes RTP custom IO work properly with pure read-only AVIOContexts as well. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	a0b7e28907	aviobuf: Partial support for reading in read/write contexts So far, aviocontexts are used either in pure-read or pure-write mode - full read/write mode doesn't work well (and implementing it is a much larger, not totally trivial change). This patch allows using avio_read and ffio_read_partial on read/write aviocontexts, where the read operations are passed through directly unbuffered, while writes are buffered as usual. This is enough to support the operations needed by packet based data transfer like in udp/rtp, where aviocontext is the only public API for hooking up custom IO.

Luca Barbato	1dd1c1c884	avio: K&R cosmetic formatting	12 years ago
Michael Niedermayer	8a34b85fa8	avio: detect implicit truncation by assert in avio_w* This check is somewhat more lenient as would be ideal because we dont know if the input is signed or unsigned Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a3fb3a670e	avio: avoid implicit truncation in avio_w* Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	b760ffdd07	aviobuf: Remove a senseless ifdef in avio_seek This seemed to assume that one never used writing avio unless muxers or networking was enabled. This ifdef is a remnant since `8fa641f8`. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	120b38b966	avio: redesign ffio_rewind_with_probe_data() This prevents a double free Fixes CID718285 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	b522000e9b	avio: introduce avio_closep	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
Luca Barbato	3093939077	avio: make avio_close NULL the freed buffer	12 years ago
Michael Niedermayer	4b9e44868b	lavf: fix avio statistics for packets directly read without the buffer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	725213545d	lavf/avio: flush internal buffer when calling avio_close() This seems the expected behavior.	12 years ago

Luca Barbato	e1e146a2d1	avio: make avio_close(NULL) a no-op Its behaviour in line with ffurl_close(NULL).	13 years ago
Reimar Döffinger	a45605a1ba	Add AVIO_FLAG_DIRECT. Allows avoiding the buffer when using avio read, write and seek functions. When using the ffmpeg executable -avioflags direct can be used to enable this mode for input files, but has no effect on output files. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	a76a2ffe9d	libavformat: Fix several "incompatible pointer type" warnings. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
Janne Grunau	a2d1d21629	avio: exit early in fill_buffer without read_packet Fixes an invalid free() with ass in avi. The sample in bug 98 passes parts of AVPacket.data as buffer for the AVIOContext. Since the packet is quite large fill_buffer tries to reallocate the buffer before doing nothing. Fixes bug 98.	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
Anton Khirnov	ddffc2fdc3	avio: add support for passing options to protocols. Not used anywhere yet, support for passing options from avio_open() will follow.	13 years ago
Martin Storsjö	6f1b7b3944	avio: Add an AVIOInterruptCB parameter to ffurl_open/ffurl_alloc Change all uses of these function to pass the relevant callback on.	13 years ago

Michael Niedermayer	a3ffe0eb76	Revert "Fix url_fopen() flag values." No longer needed after martins change to the values. Though this would have been nicer ABI wise but iam too lazy to maintain this difference This reverts commit `183401b924`.	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
