Description

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.
