| | | | | | | | | wsbh is only avilable for MIPS R2+. Provide a fallback for older processors. Signed-off-by: Jiaxun Yang <jiaxun.yang@flygoat.com> Reviewed-by: Shiyou Yin <yinshiyou-hf@loongson.cn> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/mips: Use MMI marcos to replace Loongson3 instructionsJiaxun Yang2021-07-28
| | | | | | | | | | | | | | | Loongson3's extention instructions (prefixed with gs) are widely used in our MMI codebase. However, these instructions are not avilable on Loongson-2E/F while MMI code should work on these processors. Previously we introduced mmiutils marcos to provide backward compactbility but newly commited code didn't follow that. In this patch I revised the codebase and converted all these instructions into MMI marcos to get Loongson2 supproted again.

* avcodec/tableprint_vlc: Fix building with hardcoded tablesAndreas Rheinhardt2021-07-23
| | | | | | | | | | | | This has been broken in 25c8507818d8559a6654a5b30a0f8aae11a48181, because the hacks for headers that are incompatible with building for the host in libavcodec/tableprint_vlc.h have not been adjusted. Moving AV_INPUT_BUFFER_PADDING_SIZE to defs.h which is valid for both the target as well as the host allowed to remove some of the hacks.

* 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/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".

* {configure,avcodec/libx264}: remove separate x264_csp_bgr checkJan Ekström2021-07-12

* 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>
