* 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.

* rdt: Use a separate variable to clarify the different value namespacesMartin Storsjö2015-03-05
| | | | | | | | The original flags variable contains rtpdec flags, while the rmflags variable contains RM flag bits which have a completely different definition. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Rename the free method to closeMartin Storsjö2015-02-24
| | | | | | | | | Many of these functions were named foo_free_context, and since the functions no longer should free the context itself, only allocated elements within it, the previous naming was slightly misleading. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Free depacketizers if the init function failedMartin Storsjö2015-02-24
| | | | | | | | | | | | | | This is different from how it is handled in codecs/demuxers/muxers though (where the close function isn't called if the open function failed), but since the number of depacketizers that have an .init function is quite limited, this is easy to change. The main point is that if the init function failed, we shouldn't try to use that depacketizer at all - this makes sure that the parse function doesn't need to check for the things that were initialized in the init function.

* rtpdec: Don't free the payload context in the .free functionMartin Storsjö2015-02-24
| | | | | | | | | | | | | | This makes it more consistent with depacketizers that don't have any .free function at all, where the payload context is freed by the surrounding framework. Always free the context in the surrounding framework, having the individual depacketizers only free any data they've specifically allocated themselves. This is similar to how this works for demuxer/muxers/codecs - a component shouldn't free the priv_data that the framework has allocated for it. Signed-off-by: Martin Storsjö <martin@martin.st>

* lavf: Reset the entry count and allocation size variables on av_reallocp ↵Martin Storsjö2013-09-26
| | | | | | | | | | | | | | 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>

* 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.

* rtsp/rdt: Assign the RTSPStream index to AVStream->idMartin Storsjö2011-02-11
| | | | | | | | | | | | This is used for mapping AVStreams back to their corresponding RTSPStream. Since d9c0510, the RTSPStream pointer isn't stored in AVStream->priv_data any longer, breaking this mapping from AVStreams to RTSPStreams. Also, we don't need to clear the priv_data in rdt cleanup any longer, since it isn't set to duplicate pointers. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

However, that was separated out into a new function, and the flags/timestamp are thus never updated within ff_rm_parse_packet() anymore, and thus do not need to be a pointer.
