  • How to improve the sharpness of the output video on centOS ?

    11 octobre 2019, par Mads Lee

    I’m using the same ffmpeg cmd on Windows and centOS to add timecode for the input video, the output video on centOS has low sharpness and mosaic.

    ffmpeg version :

    ffmpeg on Windows: 4.1.3 built with gcc 8.3.1 (gcc) 20190414

    ffmpeg on centOS: 4.1.0 built with gcc 5.8.5(gcc) 20150623 (Red Hat 4.8.5-16)

    ffmpeg cmd :

    ffmpeg -i \input.mp4 -vf drawtext="timecode='00\:00\:00\:00':rate=30:x=10:y=10:text=qwer:fontsize=50:fontcolor=yellow:boxcolor=black" \output.mp4

    Video screenshot :

    23 mai 2013, par Javan

    Does anyone build libaacplus2.0.2(Download here) successed for iOS ? I want ffmpeg support that.It cast me one day to build that, but failed.

    This is libaacplus2.0.2/autogen.sh, It was edited, just let it create configure file :

    #!/bin/sh
    # Run this to set up the build system: configure, makefiles, etc.
    # (based on the version in enlightenment's cvs)

    package="libaacplus"

    }

    if test "$DIE" -eq 1; then

    if test -z "$*"; then

  • Cortex-A7 instruction cycle timings

    15 mai 2014, par Mans — ARM

    The Cortex-A7 ARM core is a popular choice in low-power and low-cost designs. Unfortunately, the public TRM does not include instruction timing information. It does reveal that execution is in-order which makes measuring the throughput and latency for individual instructions relatively straight-forward. The table below lists the measured issue cycles … Continue reading
