* | avformat/aviobuf: fix flushing write buffers after seeking backward or forwardMarton Balint2017-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes aviobuf work more like traditinal file IO, which is how people think about it. For example, in the past, aviobuf only flushed buffers until the current buffer position, even if more data was written to it previously, and a backward seek was used to reposition the IO context. From now, aviobuf will keep track of the written data, so no explicit seek will be required till the end of the buffer, or till the end of file before flushing. This fixes at least one regression, fate-vsynth3-flv was broken if flush_packets option was set to false, an explicit seek was removed in 4e3cc4bdd8acedbcc703607ed0efbb64bb5c3cc4. Also from now on, if a forward seek in the write buffer were to cause a gap between the already written data and the new file position, a flush will happen. The must_flush varable is also removed, which might have caused needless flushes with multiple seeks whithin the write buffer. Since we know the amount of data written to it, we will know when to flush. Signed-off-by: Marton Balint <cus@passwd.hu>

* | avformat, ffmpeg: deprecate old rotation APIwm42017-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old "API" that signaled rotation as a metadata value has been replaced by DISPLAYMATRIX side data quite a while ago. There is no reason to make muxers/demuxers/API users support both. In addition, the metadata API is dangerous, as user tags could "leak" into it, creating unintended features or bugs. ffmpeg CLI has to be updated to use the new API. In particular, we must not allow to leak the "rotate" tag into the muxer. Some muxers will catch this properly (like mov), but others (like mkv) can add it as generic tag. Note applications, which use libavformat and assume the old rotate API, will interpret such "rotate" user tags as rotate metadata (which it is not), and incorrectly rotate the video. The ffmpeg/ffplay tools drop the use of the old API for muxing and demuxing, as all muxers/demuxers support the new API. This will mean that the tools will not mistakenly interpret per-track "rotate" user tags as rotate metadata. It will _not_ be treated as regression. Unfortunately, hacks have been added, that allow the user to override rotation by setting metadata explicitly, e.g. via -metadata:s:v:0 rotate=0 See references to trac #4560. fate-filter-meta-4560-rotate0 tests this. It's easier to adjust the hack for supporting it than arguing for its removal, so ffmpeg CLI now explicitly catches this case, and essentially replaces the "rotate" value with a display matrix side data. (It would be easier for both user and implementation to create an explicit option for rotation.) When the code under FF_API_OLD_ROTATE_API is disabled, one FATE reference file has to be updated (because "rotate" is not exported anymore).

* | 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.
