* avio: Copy URLContext generic options into child URLContextsMartin Storsjö2016-03-24
| | | | | | | | | | | | | | | Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
* lavf: add a protocol whitelist/blacklist for file opened internallyAnton Khirnov2016-02-22
| | | | | | | | Should make the default behaviour safer for careless callers that open random untrusted files. Bug-Id: CVE-2016-1897 Bug-Id: CVE-2016-1898
* urlprotocol: receive a list of protocols from the callerAnton Khirnov2016-02-22
| | | | | This way, the decisions about which protocols are available for use in any given situations can be delegated to the caller.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.
* lavf: Use RTP_MAX_PACKET_LENGTH instead of 1500Andrew Van Til2013-04-09

* cosmetics: Align muxer/demuxer declarationsMartin Storsjö2012-04-06
| | | | | | | Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: remove AVFormatParameters from AVFormatContext.read_header signatureAnton Khirnov2012-01-27

* Replace all uses of av_close_input_file() with avformat_close_input().Anton Khirnov2011-12-12

* avio: add support for passing options to protocols.Anton Khirnov2011-11-13
| | | | | Not used anywhere yet, support for passing options from avio_open() will follow.
* avformat: Pass the interrupt callback on to chained muxers/demuxersMartin Storsjö2011-11-13
| | | | | | There are a few more cases of chained demuxers, but they only use custom IO which don't do any blocking IO and thus don't need the callback.
* avio: Add an AVIOInterruptCB parameter to ffurl_open/ffurl_allocMartin Storsjö2011-11-13
| | | | | Change all uses of these function to pass the relevant callback on.
* lavf: replace av_new_stream->avformat_new_stream part II.Anton Khirnov2011-10-19
| | | | | | | | Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.
* lavf: use designated initialisers for all (de)muxers.Anton Khirnov2011-07-17
| | | | It's more readable and less prone to breakage.
* Deprecate av_open_input_* and remove their uses.Anton Khirnov2011-06-16
| | | | Deprecate the last remaining member of AVFormatParameters.
* avio: remove AVIO_* access symbols in favor of new AVIO_FLAG_* symbolsStefano Sabatini2011-04-19
| | | | | | | | 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.

* avio: move init_put_byte() to a new private header and rename itAnton Khirnov2011-02-20
| | | | | | | init_put_byte should never be used outside of lavf, since sizeof(AVIOContext) isn't part of public ABI. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* os: replace select with pollLuca Barbato2011-01-28
| | | | | Select has limitations on the fd values it could accept and silently breaks when it is reached.
* Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice.Diego Elio Pettenò2011-01-26
| | | | | 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.
* sapdec: Include sys/time.h for struct timevalMartin Storsjö2010-10-13
