* avcodec/mpegaudiodata: Unavpriv mpa_bitrate and mpa_frequency tabsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | These arrays have a size of 180 resp. six bytes. This does not make it worthwhile to export them due to the overhead this occurs; for x64 Elf/Linux/GNU: 2x2B version, 2x24B .dynsym, 24B .rela.dyn, 8B .got, 4B hash + twice the size of the name (here 20+23B). Therefore these symbols are unavprived and duplicated for shared builds. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* lavf: move AVStream.*index_entries* to AVStreamInternalAnton Khirnov2020-10-28
| | | | | | | Those are private fields, no reason to have them exposed in a public header. Since there are some (semi-)public fields located after these, even though this section is supposed to be private, keep some dummy padding there until the next major bump to preserve ABI compatibility.

| | | | | | | | | | | | | | and make it static again. These functions have been moved from nutenc to aviobuf and internal.h in f8280ff4c00eeaa245085fa9691035203abd168c in order to use them in a forthcoming patch in utils.c. Said patch never happened, so this commit moves them back and makes them static, effectively reverting said commit as well as f8280ff4c00eeaa245085fa9691035203abd168c (which added the ff-prefix to these functions).

* avformat/nutenc: Reuse dynamic buffers when possibleAndreas Rheinhardt2020-05-05
| | | | | | | | | | | | NUT uses variable-length integers in order to for length fields. Therefore the NUT muxer often writes data into a dynamic buffer in order to get the length of it, then writes the length field using the fewest amount of bytes needed. To do this, a new dynamic buffer was opened, used and freed for each element which involves lots of allocations. This commit changes this: The dynamic buffers are now resetted and reused.

* avformat: remove avio_flush() calls from the end of write_header functionsMarton Balint2020-01-07
| | | | | | | | | | | | | | To make it consistent with other muxers. The user can still control the generic flushing behaviour after write_header (same way as after packets) using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used. Therefore this change should have no adverse effect on streaming, even if it is assumed that the first packet has a clean buffer, so small seekbacks within the output buffer work even when the IO context is not seekable.

| * 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.
