* 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.

* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | 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.

* Add _XOPEN_SOURCE=600 to CPPFLAGS on NetBSD.Diego Biurrun2010-03-12
| | | | | | | | | | | | This make NetBSD compile out of the box at the cost of a hack, but a locally contained one that is preferable to the one used in the wild. Currently the NetBSD FATE box adds -D_NETBSD_SOURCE to CPPFLAGS to work around broken system headers. Since it is unlikely for NetBSD to fix their headers, it is better to use a standard flag instead of a system-specific one. As a sideeffect, this allows getting rid of a local _NETBSD_SOURCE definition. Originally committed as revision 22486 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add _NETBSD_SOURCE definition to fix compilation on NetBSD.Jorge Acereda2010-03-03
| | | | | | | | | | NetBSD is unlikely to fix their headers and the FATE box passes it as -D_NETBSD_SOURCE on the command line anyway. In this case, it's better to keep the hack well-contained within this file.
