 Hello.

 Current version doesn't recognize HDV private streams. They contain
 aperture, shutter speed, gain and original timestamps. I need to convert a
 lot of tapes to Matroska (H.264 + MP2 passthrough) and keep such
 informations as subtitles.

 I found out GStreamer had a plugin called 'hdvparse' in gst-plugins-bad:

 https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/log/gst/hdvparse

 Any chance to see this functionality ported to FFmpeg? Thank you.

 Here's the log from ffprobe.
