W!o+ 的《小伶鼬工坊演義》︰樹莓派 3 三兩事之 VLC 篇

或許因為『 omxplayer 』

About

OMXPlayer is a commandline OMX player for the Raspberry PI.
It was developed as a testbed for the XBMC Raspberry PI implementation and is quite handy to use standalone.

OMXPlayer has big dependencies that take long to compile on Raspberry Pi and usually without sucess, so I decided to make a build-bot for creating binary distributions for Raspbian (Debian with hard-float for RPi).

I didn’t wrote the code, I just provide the binary packages. If you have any problem with them you can contact me in different ways and I will try to help:

  • E-Mail: skgsergio [at] gmail [dot] com
  • Twitter: @skgsergio
  • IRC: [SkG] @ irc.freenode.net (usually online at #raspberrypi, #raspbian and many others.)

是個『命令列』程式。然而人們總是想要有個『圖形界面』的應用程式，於是許久以來，就有人開始嘗試

Tutorial: Compile VLC with HW acceleration – Jessie, RPi 2/3

by gkreidl » Sat Nov 02, 2013 8:30 am
Update March 14th, 2016:
This is now finally working again! This tutorial is for Raspbian Jessie and the RPi 2 and 3 only!If you have already VLC installed, remove it now (all packages belonging to it).
If not, it might be a good idea, to install it first and remove it again (all packages belonging to it) to get all the program dependencies installed.1) Download and unpack:
http://download.videolan.org/vlc/2.2.2/vlc-2.2.2.tar.xzFor everything else we’ll use a terminal.2) Installing the dependencies for building

……

This will also take a few minutes.

After starting VLC for the first time, change the following options:
Settings, simple, Audio: make sure, ALSA and bcm2835 are selected
Settings, simple, Video, output: select “OpenMAX IL video output”
VLC will remember these settings.

Video is displayed in an overlay, similar to omxplayer, not inside a window. On both RPi2 and 3 it will play up to 1080p video.

If audio is jerky and out of sync, check, if pulseaudio is installed on your system and remove it (only the main application package).

Enjoy!

後來友人寫了樹莓派二『 vlc 安裝 』一文，作者一旦需要首先也就這麼編譯的了。雖說如今還是『依樣畫葫蘆』，卻請讀者注意那個文本中有一行，應如下︰

./configure –-prefix=/usr –-enable-rpi-omxil –-disable-ogg –-disable-mux_ogg –-disable-mmal-codec

 

果然結果很成功的哩！僅簡單以圖為證︰

VLC 簡易偏好設定

 

如果問為什麼要作這件事呢？大概由於過去有人問

Do I still need to purchase the MPEG-2 and VC-1 license keys for the Raspberry Pi 2?

 

。即使這在樹莓派 3 之 KODI ︰

 

1.9 Enabling additional video codecs

Link
You can buy additional video codecs (VC-1 – used in some bluray discs, and MPEG-2) from the Raspberry Pi Foundation online shop. After purchase the keys are emailed to you, looking like this (invalid keys used for example):

decode_MPG2=0x1cc591c7
decode_WVC1=0x8aa09876

In order to enable additional video codecs you should modify /boot/config.txt and add these lines literally. The method may vary per distribution:

  • Manual: Open /boot/config.txt with a text editor like nano or vi, and add the keys.
  • XBian: You can add/remote your keys using XBian-config. After reboot your keys will be entered and ready to use.
  • OSMC: Go in to My OSMC -> Pi Config. Navigate to Codecs and enter your keys with the on-screen keyboard. After a reboot your keys will be entered and ready to use.
  • OpenELEC: Type mount /flash -o remount,rw to remount the boot partition in read/write mode. The file to edit is located in /flash/config.txt, and contains stubs for the license keys. Add the keys using nano or vi. There is also an unofficial add-on which can be used to enter the codec information.

 

官方版的驗證下也是需要？？！！

雖然『  Jessie 』的 VLC 也已經很新的了︰

問題是沒有『硬體影音解碼』！！？？所以 …… 怎麼得到『兩種』好處的乎☆★

可是作者還想要『第三種』的也︰

Listen to Bluetooth Audio on Your Raspberry Pi 3, Pi Zero, or Earlier Pi

By 5 commentsNews, Raspberry Pi, USB-BT4LE, Using

YouTube on the Pi

The Raspberry Pi is a handy little computer for so many uses, but Raspbian doesn’t come already set up for listening to audio over Bluetooth headphones or speakers. However, it’s not hard to do, it’s a lot of fun, and it works!. As I’m writing this, I’m listening to 40s Big Band music on my Pi 3 through my Bluetooth headphones.

The instructions in this post are for the February 26, 2016 version of version of Raspbian or Noobs, but they work with all previous versions of Raspbian Jessie. They work for the Raspberry any Pi version, although the Zero and the original Pi are not really powerful enough to stream from the internet. They work great for playing mp3 files with a media player like VLC.

Except for the Pi 3, you’ll need a Bluetooth adapter like the Plugable Bluetooth adapter. For the Pi Zero, you’ll also need a way to connect to the Internet like a Plugable USB-Ethernet adapter or WiFi adapter, along with an OTG cable and a powered hub like the compact Plugable 4-port USB 2.0 hub. Whichever Pi you use, you end up with is a great little music server that opens the door to a lot of fun projects.
