  • Encoding 4K 60Hz lossless from a capture card

    13 décembre 2017, par Alex Pizzi

    Hi all,

    I’m trying to encode 4K 30/60Hz video in a lossless format from a 4K capture card and everything I’ve tried gives me a similar error as in the linked image, [real-time buffer too full or near too full frame dropped]

    [Not mine]
    https://cloud.githubusercontent.com/assets/4932401/22171307/ef5c9864-df58-11e6-8821-4b74ce3f32d0.png

    This is the command I’ve tried most recently :

    ffmpeg.exe -f dshow -video_size 3840x2160 -framerate 30 -pixel_format bgr24 -rtbufsize INT_MAX -i video="MZ0380 PCI, Analog 01 Capture" -vf fps=30 out%d.BMP

    With the images dumped to a 10G RAM disk or 850 EVO. I’m doing this to skip the encoding step.

    I get the same error when encoding with h265 lossless and NVENC h265 lossless.

    I need the video to be lossless as it will be used to test hardware h265 encoders.

    Video source is a 4K Blu-ray.

    Any help would be greatly appreciated. Thank you.

  • checkasm : aarch64 : Don’t clobber x29 in checkasm_stack_clobber

    checkasm : aarch64 : Don’t clobber x29 in checkasm_stack_clobber

    x29 (FP) is a callee saved register and should be restored on
    
return. Instead of backing up x29 and restoring it here, back up
    
sp in a register that we are allowed to overwrite.
    

    This fixes crashes in checkasm on aarch64 since f1b3e1313851.
    
For some reason, gcc builds didn’t crash, but clang builds do.

  • lavu/riscv : helper macro for VTYPE encoding

    5 octobre 2022, par Rémi Denis-Courmont
    lavu/riscv : helper macro for VTYPE encoding

    On most cases, the vector type (VTYPE) for the RISC-V Vector extension
    
is supplied as an immediate value, with either of the VSETVLI or
    
VSETIVLI instructions. There is however a third instruction VSETVL
    
which takes the vector type from a general purpose register. That is so
    
the type can be selected at run-time.
    

    This introduces a macro to load a (valid) vector type into a register.
    
The syntax follows that of VSETVLI and VSETIVLI, with element size,
    
group multiplier, then tail and mask policies.
