* avcodec/avcodec: Don't include cpu.hAndreas Rheinhardt2021-07-22
| | | | | | | It is not used here at all; instead, add it where it is used without including it or any of the arch-specific CPU headers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/avcodec: Don't include hwcontext.hAndreas Rheinhardt2021-07-22
| | | | | | | It is no longer used directly; but it is still indirectly included via codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/avcodec: Don't include errno.hAndreas Rheinhardt2021-07-22
| | | | | | | This inclusion has been added before libavutil/error.h was split off from avcodec.h (in 60c144f700e2e362047b00704abcb694d49e549c). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/avcodec: Stop including channel_layout.h in avcodec.hAndreas Rheinhardt2021-07-22
| | | | | | Also include channel_layout.h directly wherever used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/avcodec: Stop including bsf.h in avcodec.hAndreas Rheinhardt2021-07-22

* avcodec/adpcm_data: Fix type mismatch for ff_adpcm_afc_coeffsAndreas Rheinhardt2021-07-22
| | | | | | | | According to the header it is an array of int16_t, yet it is declared as uint16_t. Fix this by using int16_t troughout and convert the definition to use values in the range of int16_t. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/adpcm: Disable dead codeAndreas Rheinhardt2021-07-22
| | | | | | | This change ensures that the linker can drop adpcm_data.o if no decoder that actually uses anything from there is enabled. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/adpcm: Use smaller scope for some variablesAndreas Rheinhardt2021-07-22
| | | | | | | | This is to avoid unused variables warnings after the code for the disabled encoders has been #if'ed away which will happen in a subsequent commit. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/adpcmenc: Deduplicate AVClassesAndreas Rheinhardt2021-07-22
| | | | | | | | The child_class_next API relied on different (de)muxers to use different AVClasses; yet this API has been replaced by child_class_iterate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/adpcmenc: #if disabled code away, fix build without ADPCM_ARGOAndreas Rheinhardt2021-07-22
| | | | | | | | | | | | | The adpcm_argo encoder does not use the data from adpcm_data.c directly; instead it shares a function with the adpcm_argo decoder that is in adpcm.c. When all the ADPCM decoders and the adpcm_argo encoder are disabled, adpcm.c is not compiled; yet the code in adpcmenc.c calling said function from adpcm.c is still present, leading to link errors. Fix this by disabling the code belonging to disabled codecs in adpcmenc.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/adpcmenc: Use smaller scope for some variablesAndreas Rheinhardt2021-07-22
| | | | | | | | This is to avoid unused variables warnings if the code for disabled encoders is #if'ed away which will happen in a subsequent commit. In case of buf it also avoids shadowing. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/dsd_tablegen: Merge header into dsd.cAndreas Rheinhardt2021-07-19
| | | | | | | | Since b492fbcc6e87094804fdf71308dc500976c6b165, the DSD tables are always initialized at runtime, so merge the dsd_tablegen.h header into dsd.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/libavcodec.v: Tighten export whitelistAndreas Rheinhardt2021-07-18
| | | | | | | | | | | | | | Currently every symbol (with external linkage) that starts with "av" is exported. Yet libaom-av1 has lots of functions that are not meant to be exported and start with "av1_" (I counted 1236); and libvpx has average_split_mvs. These functions are exported if one links these libraries statically into a shared libavcodec.so. Solve this by tightening the whitelist to "av_", "avcodec_", "avpriv_" and (as a special-case) "avsubtitle_free".

* avcodec/libdav1d: parse sequence headers in extradata if availableJames Almer2021-07-14

* {configure,avcodec/libx264}: remove separate x264_csp_bgr checkJan Ekström2021-07-12
| | | | | | We already require X264_BUILD >= 118, which includes an unconditional definition of X264_CSP_BGR in itself, thus making this check effectively always true.
* libavcodec/vorbisenc: Add missing initial_paddingGuangyu Sun2021-07-12
| | | | | | | | | | | Vorbis has priming samples at the beginning. If the initial_padding is not set in the encoder, the total sample count will be one frame fewer than it should be. The result is that we get a truncated version of encoding. initial_padding should be set to the frame_size used in vorbis_encode_frame(). Signed-off-by: Guangyu Sun <gsun@roblox.com>

* avcodec/bsf: switch to av_get_token to parse bsf list stringGyan Doshi2021-07-04
| | | | | | | | | | The recently added setts bsf makes use of the eval API whose expressions can contain commas. The existing parsing in av_bsf_list_parse_str() uses av_strtok to naively split the string at commas, thus preventing the use of setts filter with expressions containing commas. av_get_token can work with escaped commas, allowing full use of setts.
