* swscale/output: don't leave the alpha channel undefined in vuyx and xv36leJames Almer2024-08-131-32/+6
| | | | | | It's non-determistic, as shown by poisoning avfilter buffers instead of zeroing them. Signed-off-by: James Almer <jamrial@gmail.com>
* sws/riscv: depend on RVB and simplify accordinglyRémi Denis-Courmont2024-08-052-7/+5

* lavu/riscv: count bytes rather than words for bswap32Rémi Denis-Courmont2024-07-302-3/+2
| | | | This removes the dependency on Zba at essentially zero cost.

* swscale/utils: fix leak on threaded ctx init failureNiklas Haas2024-07-141-2/+1
| | | | | | | | | | | | This count gets incremented after init succeeds, when it should be incremented after *alloc* succeeds. Otherwise, we leak the context on failure. There are no negative consequences of incrementing for allocated-but-not-initialized contexts, as the only functions that reference it will, in the worst case, simply behave as if called on allocated-but-not-initialized contexts, which is in line with expected behavior when sws_init_context() fails.
* swscale: prevent undefined behaviour in the PUTRGBA macroSean McGovern2024-07-101-2/+2
| | | | | | | | | | | For even small values of 'asrc[x]', shifting them by 24 bits or more will cause arithmetic overflow and be caught by GCC's undefined behaviour sanitizer. Ensure the values do not overflow by up-casting the bracketed expressions involving 'asrc' to uint32_t. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | Every function in yuv2rgb_template.c is only compiled exactly once, so detemplatize it.

* riscv: probe for Zbb extension at load timeRémi Denis-Courmont2024-06-112-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to hysterical raisins, most RISC-V Linux distributions target a RV64GC baseline excluding the Bit-manipulation ISA extensions, most notably: - Zba: address generation extension and - Zbb: basic bit manipulation extension. Most CPUs that would make sense to run FFmpeg on support Zba and Zbb (including the current FATE runner), so it makes sense to optimise for them. In fact a large chunk of existing assembler optimisations relies on Zba and/or Zbb. Since we cannot patch shared library code, the next best thing is to carry a flag initialised at load-time and check it on need basis. This results in 3 instructions overhead on isolated use, e.g.: 1: AUIPC rd, %pcrel_hi(ff_rv_zbb_supported) LBU rd, %pcrel_lo(1b)(rd) BEQZ rd, non_Zbb_fallback_code // Zbb code here The C compiler will typically load the flag ahead of time to reducing latency, and can also keep it around if Zbb is used multiple times in a single optimisation scope. For this to work, the flag symbol must be hidden; otherwise the optimisation degrades with a GOT look-up to support interposition: 1: AUIPC rd, GOT_OFFSET_HI LD rd, GOT_OFFSET_LO(rd) LBU rd, (rd) BEQZ rd, non_Zbb_fallback_code // Zbb code here This patch adds code to provision the flag in libraries using bit manipulation functions from libavutil: byte-swap, bit-weight and counting leading or trailing zeroes.
