Thanks, Carl. I'm going to respond first to the most global
architectural issue (as I'm able to recognize issues and discriminate
between them).
FFmpeg (and digital transcoders in general) doesn't know about fields,
it can only work with frames. (This is also related to the specifications
of sane video codecs.)
If ffmpeg doesn't know about fields, how can it decode interlaced content?
- Mark.
PS: I'm retired, but in a prior life I actually designed some video
hardware, NTSC (Atari research) & satellite gear (FPGA chips for HDTV
distribution), but the problem I have is interpreting what appears to me
to be inconsistent or ad hoc terminology in ff-docs. I'm attempting to
develop a video recognizer useful for preselecting HandBrake presets. So
far I've been wildly successful, but I have a few loose ends. I will
follow this message with specific questions regarding the details you
addressed, okay? - Thanks again.
