using raspberry pi camera with ffmpeg (hardware accelerated)

Using Raspberry Pi Camera with ffmpeg

Capturing video from the rpi camera with ffmpeg can vary from less than 5% to 100% of the CPU (rpi zero) depending on ffmpeg using the hardware acceleration or not.

On many github issues one finds the suggestion of using h264_omx codec to use the gpu - but it does not ship with the default ffmpeg on Raspbian.

Instead I found that one can use the v4l2 driver provided by raspbian to get hardware accelerated h264 output. Also setting the video size will save one from using a (cpu) scale filter.

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.

Created September 2, 2019 03:40 — forked from G-UK/Raspberry Pi 4 Arm64 Kernel Cross-Compile.md
Building the Raspberry Pi 4 Arm64 Linux Kernel

Introduction

The objective of these instructions is to build a stock 64bit Linux Kernel for use on the Raspberry Pi 4B on a Debian x64 machine (Windows Subsystem for Linux in my case), and deploy on the Raspberry Pi.

Also included are some additional instructions for installation of 64bit Userland firmware to go with the 64bit Kernel.

Notes:

  • Transfer to Pi is using my NAS in this example, replace with shared drive/memory stick etc. as required.
    • (N: drive on Windows and /mnt/NAS on Linux in this example).
  • For a specific Kernel version replace the 4.19 with the wanted version in the git clone command.
  • Greater than 3GB RAM only currently available on Kernel 4.19

----------------
* Setup
In order to run Android system inside container, you need two kernel
modules: ashmem_linux and binder_linux. Since Debian kernel 4.17, these
two modules are enabled. You can find theme at,
/lib/modules/`uname -r`/kernel/drivers/android/binder_linux.ko and
/lib/modules/`uname -r`/kernel/drivers/staging/android/ashmem_linux.ko.
