This produces some output for each converted frame. If you want to see some output during conversion use the additional option -verbose=2. Note that ham_convert is about 10-15 times slower than ffmpeg. To convert a video into a HAM8 CDXL file: agaconv -color-mode=ham8 myvideo.mp4 myvideo.cdxl agaconv -help should show this path as default value for the '-hc-path' option now. Step 4 stores the absolute path to ham_convert in AGAConv's default config file. Ham_convert is now installed on your system and integrated into the AGAConv conversion pipeline. agaconv -change-config -hc-path=$PWD/ham_convert.wget -O ham_convert.zip (Download ham_convert).sudo apt install wget zip default-jdk xvfb (xvfb is only required when using the Microsoft Ubuntu App).Here are the steps to download and integrate it with AGAConv: It is not included in the PPA package because it is not open-source software. However, above command lines are sufficient for installation, you do not need to visit the PPA webpage for installation of the package.įor HAM conversions the tool ham_convert can be added to AGAConv. The manual can be viewed with the command man agaconv.ĭetails about the PPA Package can be found on the AGAConv PPA page. The package also installs the manual as a Linux man page. For HAM6/8 videos ham_convert must be installed as well.Īfter installation a video can be converted as follows: agaconv myvideo.mp4 myvideo.cdxl After installation agaconv is ready to convert any MPEG4 video (and other formats) to CDXL in AGAx and OCSx screen modes. This downloads and installs the package with all required dependencies. sudo add-apt-repository ppa:m-schordan/agaconv - start here if you have added other PPAs before.sudo apt install software-properties-common.sudo apt update - start here if this is the very first PPA being added to your system.The binary distribution can be downloaded and installed with apt on Ubuntu as follows (the correct version is selected automatically): The AGAConv Manual describes all command line options, the use of configuration files, and contains a list with several usage examples (see Section Examples).ĭistribution Linux Binary Distribution - PPA Installer AGAConv encodes extracted graphics and audio data into a CDXL video file.Starting with version 0.9.5 it can also invoke the graphic converter ham_convert to generate HAM8/HAM6/EHB frames.AGAConv invokes ffmpeg to extract and convert frames to PNG files.The generated videos were tested on a classic Amiga 4000/60 with AGABlaster and Amiga OS with original graphics and sound hardware. 24-bit colors are supported in RGB 3-byte format (same as IFF/ANIM CMAP chunk body data).Frequency is automatically adjusted (if necessary) such that all frames have the same size and data sections are 32bit aligned on disk.Encoding of standard CDXL videos (fixed number of bitplanes).With 24-bit color palette and variable length frames.Encoding of custom CDXL videos (minimal number of bitplanes in each frame).HAM6, EHB, 12 bit colors (requires ham_convert).HAM8, 24 bit colors (requires ham_convert).Configuration file allows to set any options as default. In addition to the original 12-bit colors, AGAConv also supports 24-bit colors, as supported by Commodore Amiga AGA systems released in 1992+. The CDXL format is a simple streaming format, consisting of linear concatenated chunks (packets), each with an uncompressed frame and associated audio data. The CDXL format was created by Commodore primarily for the Commodore CDTV, released 1991, to permit playback of video from CD-ROM in the early 1990s. The first Commodore-Amiga computer with the AGA chipset was released in 1992. It combines some existing tools to convert videos (MP4, etc.) into the CDXL format which can be played with AGABlaster or other CDXL players on an AGA Commodore-Amiga computer. AGAConv is a CDXL video converter for Commodore-Amiga computers. This is a retro computing just-for-fun project. 1: agaconv 1.0.0 released (with binary PPA Installer for Ubuntu 20.04, 22.04)ĪGABlaster YouTube channel showing agaconv converted Amiga videos.
