2012-01-06avio: Add an URLProtocol flag for indicating that a protocol uses networkMartin Storsjö
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>
2011-12-11Fix a bunch of common typos.Diego Biurrun
2011-12-01proto: Use .priv_data_size to allocate the private contextMartin Storsjö
This simplifies the open functions by avoiding one function call that needs error checking, reducing the amount of extra bulk code. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-11-09udp: Allow specifying the local IP addressMartin Storsjö
This is useful if sending multicast data on a host with multiple interfaces. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-06-30udp: Fix a compilation warningMartin Storsjö
This fixes this compilation warning, by making endptr a non-const pointer, as required by strtol: In function ‘udp_open’: warning: passing argument 2 of ‘strtol’ from incompatible pointer type Signed-off-by: Martin Storsjö <martin@martin.st>
2011-06-24udp: Receive on the remote port number, if no local port is setCan Wu
For a unicast udp stream to localhost:1234, currently ffplay udp://:1234?localport=1234 works, but ffplay udp://:1234 doesn't work. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-05-12configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun
Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.
2011-05-09udp: Fix receiving RTP data over multicastMartin Storsjö
Earlier, AVIO_RDWR was handled as READ, and all the checks for the AVIO_WRONLY flag explicitly meant the write-only case. When changed from old AVIO/URL contants to AVIO_FLAG in 59d96941f0285a5, these comparisons were updated incorrectly, by mapping checks for AVIO_WRONLY to checks for AVIO_FLAG_WRITE. When receiving RTP over UDP, the urlcontext is opened with READ_WRITE flags. This patch updates the flag comparisons to check for the same conditions as the code did prior to 59d96941f0285a5. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-04-20libavformat: Make protocols pass URLContext as log context where availableMartin Storsjö
Since the libavformat major bump, URLContext contains an AVClass, making it a usable log context. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-04-19avio: remove AVIO_* access symbols in favor of new AVIO_FLAG_* symbolsStefano Sabatini
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.
2011-04-19lavf: remove FF_API_UDP_GET_FILE cruftAnton Khirnov
2011-04-08lavf: use designated initializers for all protocolsAnton Khirnov
This is more readable and makes it easier to reorder URLProtocol members.
2011-04-07avio: move extern url_interrupt_cb declaration from avio.h to url.hAnton Khirnov
2011-04-07avio: AVIO_ prefixes for URL_ open flags.Anton Khirnov
2011-04-07proto: factor ff_network_wait_fd and use it on udpLuca Barbato
Support the URL_FLAG_NONBLOCK semantic and uniform the protocol. The quick retry loop is already part of retry_transfer_wrapper. The polling routine is common to the network protocols: udp, tcp and, once merged, sctp.
2011-03-23avio: make udp_set_remote_url/get_local_port internal.Anton Khirnov
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-03-15Use AVERROR_EXIT with url_interrupt_cb.Nicolas George
Functions interrupted by url_interrupt_cb should not be restarted. Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish when the underlying system call was interrupted and actually needed to be restarted. This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed content). Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-02-23libavformat: Remove FF_NETERRNO()Martin Storsjö
Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR() error codes. Provide fallback definitions of other errno.h network errors, mapping them to the corresponding winsock errors. This eases catching these error codes in common code, without having to distinguish between FF_NETERRNO(EAGAIN) and AVERROR(EAGAIN). This fixes roundup issue 2614, unbreaking blocking network IO on windows. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-02-17Move find_info_tag to lavu and add av_ prefix to itAnton Khirnov
Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
2011-02-10udp: Enable address reuse by default for multicastDavid Fries
Keep the original corner case behaviour, where reuse is enabled for the case where no argument is given to the reuse url option. Signed-off-by: Martin Storsjö <martin@martin.st> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-01-28os: replace select with pollLuca Barbato
Select has limitations on the fd values it could accept and silently breaks when it is reached.
2011-01-27Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò
This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts.
2011-01-06udp: Allow specifying the connect option in udp_set_remote_url, tooMartin Storsjö
If the remote address is updated later with this function, the caller shouldn't set the connect option until in this call. Originally committed as revision 26245 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-15add FF_API_UDP_GET_FILE define to disable the deprecated udp_get_file_handle()Aurelien Jacobs
public function Originally committed as revision 25481 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-08ReindentMartin Storsjö
Originally committed as revision 25406 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-08udp: Add an option for connecting the udp socketMartin Storsjö
This allows us to find out the local sending address via getsockname, otherwise we just get INADDR_ANY (or similar for v6). This also makes writes return ECONNREFUSED if nobody is listening on the receiving port. Originally committed as revision 25405 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-07Convert ff_is_multicast_address to take a struct sockaddr parameterMartin Storsjö
Not all users of this function will have a full struct sockaddr_storage available, and casting other sockaddrs to sockaddr_storage is wrong, while any sockaddr can be cast to a base sockaddr. Originally committed as revision 25388 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-07Share the is_multicast_address functionMartin Storsjö
The header probably isn't the right permanent place for this function, but it is quite small, and consensus seems to be that it can stay in the header for now, instead of creating a new file network.c just for this one. Originally committed as revision 25387 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-07Move multicast address identification fallback macros to network.h from udp.cMartin Storsjö
Originally committed as revision 25386 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-05udp: Define _DARWIN_C_SOURCEMartin Storsjö
This is required in order to get the IP_MULTICAST_TTL define. Originally committed as revision 25351 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-10-05udp: Return the actual error code on errors, instead of AVERROR(EIO)Martin Storsjö
Originally committed as revision 25350 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-09-20Check for the IPPROTO_IPV6 define before using itMartin Storsjö
This fixes building on FreeBSD in some configurations, if the IPv6 multicast structs are available, but IPPROTO_IPV6 isn't defined. Originally committed as revision 25147 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-28Check for udp_set_remote_url error.Reimar Döffinger
Fixes issue 1784 (hang with nonsense URL/no network available). Originally committed as revision 24575 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-07-02Fix misspelled parameter names in Doxygen documentation.Diego Biurrun
This fixes one Doxygen warning each. Originally committed as revision 23970 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-27Make ff_url_split() publicMåns Rullgård
ff_url_split() is retained as an alias, as it was used by ffserver, to avoid breaking ABI compatibility with it. Originally committed as revision 23822 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-14Cosmetics: Change connexion to connection in code commentsMartin Storsjö
Originally committed as revision 23601 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-06-01Declare the url_write buffer parameter as constMartin Storsjö
Originally committed as revision 23401 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-26Don't report EINTR from select as an error, retry select insteadMartin Storsjö
Originally committed as revision 22694 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-15move ff_url_split() and ff_url_join() declarations to internal.hAurelien Jacobs
those functions are not part of the public API Originally committed as revision 22534 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-08Rename url_split to ff_url_splitMartin Storsjö
Since this function isn't in the public API, it should have an ff_ prefix. Originally committed as revision 22321 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Don't explicitly initialize networking in the tcp and udp protocolsMartin Storsjö
Networking is always initialized when opening protocols. Originally committed as revision 22227 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-01Explicitly set struct addrinfo to NULL if getaddrinfo failed instead ofReimar Döffinger
assuming getaddrinfo will have done this. Originally committed as revision 22123 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-22Make style a little bit more K&R'ish.Ronald S. Bultje

2010-01-21Remove IPv4-only codepath. Patch by Martin Storsjö <$first $first st>.Martin Storsjö
Originally committed as revision 21365 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-03-03Add url_get_file_handle(), which is used to get the file descriptorRonald S. Bultje
associated with the I/O handle (e.g. the fd returned by open()). See "[RFC] rtsp.c EOF support" thread. There were previously some URI-specific implementations of the same idea, e.g. rtp_get_file_handles() and udp_get_file_handle(). All of these are deprecated by this patch and will be removed at the next major API bump. Originally committed as revision 17779 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk
