XML2CPL Tool

XML2CPL is a command line tool that takes XML timeline files from programs like Clipster and Final Cut Pro and converts them to compliant CPL.xml files.  The generated CPL.xml files pass validation by Netflix's Photon validation tool.

XML2CPL dependencies

Environment Variables

  • TEMP - This is usually defined in Windows.  It should point to a temp directory.
  • PHOTON_HOME - Should point to the Netflix Photon directory.
  • JAVA_HOME - Should point to to the JDK directory.  Pretty standard for a Java install.

Current XML2CPL work flow

  1. Take a Final Cut Pro or Clipster timeline file which is in XML format and references MOV and WAV essences
  2. Run that timeline file through my XML2CPL program
  3. XML2CPL will wrap MOV and WAV into MXF files
    - No transcoding done, just wrapping into an MXF container using raw2bmx
    - MediaInfo is used to figure out elementary stream type to send proper source flag to raw2bmx
  4. XML2CPL runs the MXF files through Netflix’s IMFTrackFileReader Photon Java program, which generates the EssenceDescriptors
  5. XML2CPL uses the generated EssenceDescriptors in the generated CPL.xml file.
  6. XML2CPL also generates an ASSETMAP.xml so that there is a mapping of UUIDs to file names on disk.

Work to do

  • Update Clipster support to latest Photon compliant XML2CPL, currently just Final Cut Pro works
  • Add support for other editor timelines like: Avid, Davici Resolve, ColorFront Transkoder, Ateme, Deluxe customized EDL
  • Add MXF wrapping support for: MP4, MPEG2
  • Maybe check out asdcplib for MXF creation: http://www.cinecert.com/asdcplib/

Work Completed

  • Figure out how to automate the essence description flag that needs to be passed to raw2bmx, like --vc3_1080p_1253, maybe integrate MediaInfo to help with this
  • Test my generated CPL.xml, ASSETMAP.xml, and MXF files against Netflix IMFTool (CPL Editor) - THIS DOES NOT MAKE SENSE, as xml2cpl does not create J2k mxf essences or support files like PKL.xml.  Only a complete IMF package can be tested with IMFTool, and a complete IMF package is what Comprimato will provide us.

FFMPEG Deinterlacing Modes

FFMPEG has multiple supported deinterlacing filters.  Here they are: 10.14 bwdif Deinterlace the input video ("bwdif" stands for "Bob Weaver Deinterlacing Filter"). Motion adaptive deinterlacing based on yadif with the use of w3fdif and cubic interpolation algorithms. It accepts the following parameters: mode The interlacing mode to adopt. It accepts one of the following values: 0, send_frame Output one frame for each frame. 1, send_field Output one frame for each field. The default value is send_field. parity The picture field parity assumed for the input interlaced video. It accepts one of the following values: 0, tff Assume the top field is first. 1, bff Assume the bottom field is first. -1, auto Enable automatic detection of field parity. The default value is auto. If the interlacing is unknown or the decoder does not export this information, top field first will be assumed. deint Specify which frames to deinterlace. Accept

Remote debugging with GDB and GDBServer on Alpine and Visual Studio Code

Skip to end of metadata o to start of metadata gdb and gdbserver can be used in combination to provide debugging capabilities over the network.   gdbserver  is run on the machine you want to debug.   gdb  is run on the machine you want to debug from, usually your local machine. More  here . Before we get started, we need some software.  Alpine 3.8 will be the gdbserver. NFS We will be using nfs (Network File System) to mount a remote directory and have it look like a local directory.  We will cd to the nfs mounted directory which contains the program we want to debug before we launch gdb.  This way the program and symbols will match.  gdb will be running on your local client, but it will be launched when in a directory on the gdbserver's system. More than you wanted to know about  nfs . To set up nfs, you will need nfs software on your server and your client. SERVER  (Your Alpine machine) - Add nfs support: % apk add nfs-utils - Edit /etc/exports,

Build FFMPEG for Windows Using Visual Studio Toolchain

FFMPEG for Windows is built under MinGW or Cygwin.  We will be using MinGW. You may need ZLib, the ZLib provided with MinGW does not come with a .a file for some reason.  You can find ZLib at  https://zlib.net/ Build Zlib so that you get zlib.lib. Follow this page:  https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC NOTE: When following the instructions on the above page, they only give a configure command for a release version, which is: ./configure --target-os=win64 --arch=x86_64 --toolchain=msvc If you want to do a full debug build, try this: ./configure --target-os=win64 --arch=x86_64 --toolchain=msvc --extra-cflags=" -EHa -nologo -D 'DEBUG' -D 'WINDOWS' -D 'HAVE_STRUCT_TIMESPEC' -D 'API_EXT_PARAM_LIST'" --enable-debug --disable-stripping --disable-optimizations --disable-cuda --disable-cuvid --disable-d3d11va --disable-dxva2 --disable-nvenc --disable-vaapi --disable-vdpau You should now be ready to use ffmpeg in a
