* avcodec/ac3: Move non-(de|en)coder-only parts out of ac3.hAndreas Rheinhardt2022-05-151-1/+0
| | | | | | | | | | Move AC3HeaderInfo into ac3_parser_internal.h and the rest into a new header ac3defs.h. This also breaks an include cycle of ac3.h and ac3tab.h (the latter now only needs ac3defs.h). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/ac3tab: Unavpriv ac3_channel_layout_tabAndreas Rheinhardt2022-01-041-14/+0
| | | | | | | | | | | | | | | | | It is small (16 B) and therefore the overhead of exporting it more than outweighs the size savings from not having duplicated symbols: When the symbol is no longer avpriv, one saves twice the size of the string containing the symbols name (2x30 byte), two entries in .dynsym (24 bytes each on x64), one entry in the importing libraries .got and .rela.dyn (8 + 24 bytes on x64) and two entries for the symbol version (2 bytes each) and one hash value in the exporting library (4 bytes). (The exact numbers are of course different for other platforms (e.g. when using dlls), but given that the strings saved alone more than outweigh the array size it can be presumed that this is beneficial for all platforms.)

* avcodec/ac3tab: Remove unused ff_eac3_default_chmapAndreas Rheinhardt2021-02-241-13/+0
| | | | | | | | Added in 0c79b1402a48a99f32435a0f5ad2364c58c6fcf3 to use it in a function that was never used and was itself removed in 676f1f533e2c2960d81784188592a066b9ff1c3d. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| | | | | | | | | This is required to use it as an AVCodec.supported_samplerates array. Adding the sentinel has been forgotten in 4679a474.

| * ac3enc: add channel coupling supportJustin Ruggles2011-05-241-0/+7
| | | | | | | | | | | | | | | | | | Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.

| * Merge libavcore into libavutilReinhard Tartler2011-02-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
