Anton Khirnov	ec4c483976	lavf: add a protocol whitelist/blacklist for file opened internally Should make the default behaviour safer for careless callers that open random untrusted files. Bug-Id: CVE-2016-1897 Bug-Id: CVE-2016-1898	9 years ago
Anton Khirnov	8c0ceafb0f	urlprotocol: receive a list of protocols from the caller This way, the decisions about which protocols are available for use in any given situations can be delegated to the caller.	9 years ago
Anton Khirnov	cae448cfbf	aviobuf: add a private data struct for avio_open()ed contexts It will be useful in the following commits.	9 years ago
Vittorio Giovara	059a934806	lavc: Consistently prefix input buffer defines Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Luca Barbato	252d6200c3	avio: Add avio_put_str16be	10 years ago
Vittorio Giovara	bff0349d9d	avio: Add avio_read wrapper to simplify error checking Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Diego Biurrun	b97f427fb5	lavf: Explicitly convert types at function pointer assignment This fixes a number of "assignment from incompatible pointer type" warnings.	10 years ago
Martin Storsjö	c86d8aed74	avio: Rename avclass symbols relating to avio Don't prefix them ffio_url, which is misleading, sounding too much like the urlprotocol layer (like ffurl_*). Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	8a273a7460	avio: Add an internal utility function for freeing dynamic buffers Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Luca Barbato	3c18a7b188	avio: Do not consider the end-of-buffer position valid Trigger a refill if the seek action moves the pointer at the end of the buffer. Before this patch the read action following the seek would trigger the refill, while write action would write outside the buffer. In the Libav codebase few muxers seek forward outside of what already has been written so it is quite unlikely to experience the problem with the default buffer size.

Vittorio Giovara	d7f530b0d6	aviobuf: check context before using it Avoid a possible null pointer dereference. CC: libav-stable@libav.org Bug-Id: CID 1135769	10 years ago
Alessandro Ghedini	32d05934ab	mp3dec: decode more data from Info header Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Martin Storsjö	d07b51bf07	aviobuf: Handle a NULL buffer in avio_close_dyn_buf This simplifies proper error handling in rtsp.c/rtspdec.c. When broadcasting over RTSP in TCP mode, the AVIOContext is closed and recreated for each sent packet, and if the recreation fails, we might try to close a NULL buffer when freeing things at the end. Previously, if recreating the buffer in rtspdec.c failed, this would crash later due to trying to close a NULL buffer. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	d872fb0f7f	lavf: Reset the entry count and allocation size variables on av_reallocp failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
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>	12 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>	12 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>	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.

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
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	e1e146a2d1	avio: make avio_close(NULL) a no-op Its behaviour in line with ffurl_close(NULL).	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

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
