Closed dericed closed 2 weeks ago

dericed commented 6 months ago

/usr/local/bin/dvrescue "device://84:3c0a102a:00000000" --control "/dev/tty.RS422 Deck Control" --decklink-video-mode ntsc --decklink-video-source composite --decklink-audio-source embedded --decklink-timecode-format vitc -m test234.mkv

Command just hangs and leaves a 577 byte output.

$ xxd test234.mkv

@g-maxime an idea why no frame?

dericed commented 3 months ago

I'm rerunning this with version 20240330 and the same command.

With the deck stopped, I run the command /usr/local/bin/dvrescue "device://84:3c0a102a:00000000" --control "/dev/tty.RS422 Deck Control" --decklink-video-mode ntsc --decklink-video-source composite --decklink-audio-source embedded --decklink-timecode-format vitc -m test234.mkv and then I get a 12M output (two are attached). But the capture quits before any frame is received: test235.mkv.zip test234.mkv.zip So the events are:

For a third try, I put the deck into play mode, and then run command and this works.
