- Probe: ffprobe -v error -show_format -show_streams "Hdhub4u.tax.mkv"
- Extract video: ffmpeg -i "Hdhub4u.tax.mkv" -c copy -map 0:v:0 out_video.h264

On macOS: Get Info or use Terminal: mdls "Hdhub4u.tax.mkv".
On Linux/macOS Terminal: file "Hdhub4u.tax.mkv" to identify type, and mediainfo "Hdhub4u.tax.mkv" (if installed) for container/codec details.
