* | avcodec, avformat: deprecate anything related to side data mergingwm42017-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deprecates anything that has to do with merging/splitting side data. Automatic side data merging (and splitting), as well as all API symbols involved in it, are removed completely. Two FF_API_ defines are dedicated to deprecating API symbols related to this: FF_API_MERGE_SD_API removes av_packet_split/merge_side_data in libavcodec, and FF_API_LAVF_KEEPSIDE_FLAG deprecates AVFMT_FLAG_KEEP_SIDE_DATA in libavformat. Since it was claimed that changing the default from merging side data to not doing it is an ABI change, there are two additional FF_API_ defines, which stop using the side data merging/splitting by default (and remove any code in avformat/avcodec doing this): FF_API_MERGE_SD in libavcodec, and FF_API_LAVF_MERGE_SD in libavformat. It is very much intended that FF_API_MERGE_SD and FF_API_LAVF_MERGE_SD are quickly defined to 0 in the next ABI bump, while the API symbols are retained for a longer time for the sake of compatibility. AVFMT_FLAG_KEEP_SIDE_DATA will (very much intentionally) do nothing for most of the time it will still be defined. Keep in mind that no code exists that actually tries to unset this flag for any reason, nor does such code need to exist. Code setting this flag explicitly will work as before. Thus it's ok for AVFMT_FLAG_KEEP_SIDE_DATA to do nothing once side data merging has been removed from libavformat. In order to avoid that anyone in the future does this incorrectly, here is a small guide how to update the internal code on bumps: - next ABI bump (probably soon): - define FF_API_LAVF_MERGE_SD to 0, and remove all code covered by it - define FF_API_MERGE_SD to 0, and remove all code covered by it - next API bump (typically two years in the future or so): - define FF_API_LAVF_KEEPSIDE_FLAG to 0, and remove all code covered by it - define FF_API_MERGE_SD_API to 0, and remove all code covered by it This forces anyone who actually wants packet side data to temporarily use deprecated API to get it all. If you ask me, this is batshit fucked up crazy, but it's how we roll. Making AVFMT_FLAG_KEEP_SIDE_DATA to be set by default was rejected as an ABI change, so I'm going all the way to get rid of this once and for all.

* | lavc/lavf: transmit stream_id information for mpegts KLV data packetsStefano Sabatini2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | This allows to copy information related to the stream ID from the demuxer to the muxer, thus allowing for example to retain information related to synchronous and asynchronous KLV data packets. This information is used in the muxer when remuxing to distinguish the two kind of packets (if the information is lacking, data packets are considered synchronous). The fate reference changes are due to the use of av_packet_merge_side_data(), which increases the size of the output packet size, since side data is merged into the packet data.
