ddennedy / dvgrab Goto Github PK

I have just discovered this software and it makes my day as i can backup all my minidv tapes full of memories. I know this is not an issue but didn't know where to thank you. People like you makes the linux comunity the best in the world. Thanks.

I was grabbing footage from a tape as follows

dvgrab --autosplit=15 --timestamp --size 0 --rewind --format dv2 --opendml Florida-

when dvgrab suddenly output lots of messages

# no audio

The resulting output file was corrupt from that point on. When I play it, I hear audio all the time(!), but video stops playing from that point.

Can someone provide me with information to compile dvgrab for MacOS? Actually libraw1394 depends on epoll which is Linux only. That’s wehere I’m stuck.

Thanks,
Florian

Hi,

I have been trying to setup a DTE record device using dvgrab. The recordonly (-r) option is key to this because, as I understand it, it should not starting capturing anything until the camera is recording. Here is my command:

dvgrab -recordonly -autosplit foo-

I run this when the camera is in record pause mode. dvgrab starts capturing immediately. If I then press record it then starts capturing a new file, and again when I put the camera back into record pause. Basically each time I press the record trigger it starts capturing a new file, but it is never in a pending state waiting for the camera to start recording. Perhaps I'm doing something wrong here but I thought that was the expected behavior.

I have noticed that if I remove -recordonly from the command the behaviour is exactly the same, so it is as if the recordonly param is being ignored. If I remove the autosplit it starts capturing straight away to one big file. I cannot get it to wait for the signal to start capturing. I'm using version 3.5 and have used the compiled version and one I compiled from source and they behave exactly the same. My cameras are mainly HDV cameras but I've tried them in DV output mode and it's just the same. Can anyone help me out here.

Thanks,
Richard

I always get a single-frame warning when trying to process previously captured RAW DV file.
Reproduces for every RAW DV file I've tried!

Also, if I run the same command multiple times, the capture result is sometimes different.

Dear Dan,

the grabbed DV (also AVI) files have a wrong aspect ratio when viewed on MacOS, it is 4:3 rather than 16:9. On Linux the aspect ratio is fine.

It tried dvgrab 3.4 and I rebuild dvgrab from sources. Same behavior.

I observed that "transcoding" a dv file to a dv file using FFmpeg solves the issue (but the Creation Time get's lost): ffmpeg -i in.dv out.dv

Do you have any ideas to solve the issue (instead of "transcoding" and loosing metadata)?

Thanks for still maintaining this highly useful piece of software!

Best regards,
Erik

Hi,

I'm using dvgrab 3.5 from Ubuntu 16.10 to grab video footage from a MiniDV camcorder.

Ideally dvgrab would only auto-split files where there is actually a discontinuation in timecode or the "new recording" flag set -- but for some reason this doesn't work in a reliable way, dvgrab splits files where it shouldn't, because it's a contiguous recording.

So I tried using --autosplit=5 to make it create separate files only if there is at least a gap of 5 secs. But not even this works properly, too many splits again.

Any clue what's going on? Can I somehow help debugging this? Would be really great if this could be fixed, as with iMovie under macOS or Movie Maker under Windoze I can't capture some of my tapes at all (strangely enough, also too many splits occur, or there is an error message "no data from device.")

Thanks!

Hi Dan

Pardon me if I tackle this problem in the wrong way, but I am searching for days now for a solution.

I have a Sony HDV (HDR-HC1E) video camera. Capturing DV works 100% but HDV 1080i the m2t files don't join seamlessly on the editor (Kdenlive) timeline.

The last frames are missing some audio and have extra video frames so that a smooth joint of files is impossible and also the sync with other streams is out by 4 or more frames.

There must be a lot of these cameras still in use and people who also would like to move to HDV.

I would appreciate if you can give some advice or still better a solution/fix.

Command used: "dvgrab -format hdv -autosplit Hcap-" (adding more buffers don't change anything)

Regards
Henry

dvgrab 3.5 keeps the final captured file open until rewind of the tape is done. It should close the file prior to rewinding the tape.

Attempting to use bootstrap to invoke autoreconf results in the following:

./bootstrap
autoreconf: 'configure.ac' or 'configure.in' is required

sure enough, there are no autoconf files and no configure provided. If that is intentional, then perhaps a Makefile would suffice.

dvgrab -srt -size 0 -I nonexisting_file.dv doesn't produce any warning and doesn't react to Ctrl-C.
