libam7xxx-0.1.6 released

The libam7xxx-0.1.6 release is out; it's a maintenance release with no big new features.

libam7xxx is a library to communicate with USB pico-projectors like, for instance, the Philips/Sagemcom PicoPix devices; you can read more about it in the previous stories:

Here is an overview from the NEWS file of the changes accumulated since the previous release:

News for v0.1.6:
================

  * Fix some ffmpeg compile time deprecation warnings in am7xxx-play
  * Fix some fmmpeg runtime warnings
  * Don't dump the last frame unconditionally in am7xxx-play when in DEBUG
    mode, add an option to enable the frame dump, but this is only active in
    DEBUG mode
  * Fix some compilation warnings from clang
  * Replace deprecated FFmpeg API symbol PIX_FMT_NV12 in am7xxx-play (Thanks
     to Andreas Cadhalpun)
  * Fix the Length field in the switch command in am7xxx-modeswitch (Thanks to
    Balasubramanian S)
  * More robust handling of USB configurations
  * More robust handling of kernel driver detachment (Thanks to Andrea
    Console)
  * Minor documentation cleanups
  * Minor build system improvements (am7xxx-play can now build without XCB,
    but some functionalities will not be available)
  * Misc code cleanups
  * Relicense the example under GPL-3+

The Debian packages have been kindly uploaded to Unstable by Gregor Herrmann.

Hello, I am a complete noob

Hello,

I am a complete noob at this and was wondering if you have a way to use this through wine for a PPX2340 projector. Also I try to download the all but it states I need a password. Any help with that?

Hi Robert, the driver works

Hi Robert,

the driver works just fine on linux, it makes no sense to use it with WINE. Where does it ask for a password? Please be more specific.

Also, I am not sure if the PPX2340 is supported, please contact me via email so we can verify that.

Ciao, Antonio

Hi, I'm also interested in

Hi,

I'm also interested in making a PPX2340 work on Linux, in particular on Ubuntu 15.04. Any progress on this side?

Thanks!

Hi Antonio,

I'm trying to cross compile for Windows on Ubuntu Precise, but when I 'make' I get ...

Hello, I'm using Ubuntu

Anonymous's picture

Hello, I'm using Ubuntu Xenial 16.04 (Mint 18) with kernel 4.4.0-21-generic.

I have a Acer C112 DLP picoproyector. I'm installed libam7xxx packages:


$ dpkg -l | grep libam7
ii libam7xxx0.1 0.1.6-2 amd64 library for accessing am7xxx based devices
ii libam7xxx0.1-bin 0.1.6-2 amd64 library for accessing am7xxx devices - utilities

When I connect the projector, this is my syslog:

Disconnects the device.

Any idea?
