Re: [FFmpeg-user] Question on Segment TImes
The tape deck is a Sony DSR-45 (not the “A” model). The tapes are pre-recorded studio dubbing masters. When I do ffprobe with avfoundation it produces this output: Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc Stream #0:1: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s I was unable to map anything resemble 0:1 or 0:a:0 coming in from the deck. Once it was in an DV file, it worked as expected. I had not thought of this before, but perhaps I can map 0:v:1 to audio? Maybe it sees it all as a video.

I’m not sure how AVFoundation splits them up or isolates the detected timecode or decide to join all the streams together, but I presume it’s similar to the audio fixup menu options in FCPX import media window. I’m curious if this would work, but have you tried artificially increasing the video size (via framerate, frame size, etc) to make it into what would be considered HDV, or even DVCPRO and try adding the audio streams then?

Also I don't know how AVFoundation actually archives the data, I would really get a build with native IEEE1394 device control/communication library support, since if you use AVFoundation then I doubt the problems in FCPX are going to go away, or at least not all of them. > On Apr 4, 2020, 2:11 AM -0700, Gyan Doshi , wrote: >> >> >> On 04-04-2020 11:59 am, Colin Bitterfield wrote: >>> I am trying to segment split a stream coming in from AVFOUNDATION >>> >>> ffmpeg -benchmark_all -stats -loglevel debug -copyts \ >>> -f avfoundation -capture_raw_data true -pix_fmt 0rgb -i DV-VCR -q 0 \ >>> -map 0 -c:v copy -c:a copy -segment_time 00:00:10 \ >>> -f segment 374_%03d.dv -y >>> >>> _ I have tried various combinations of “-increment_tc” and >>> "-reset_timestamps 0" >>> >>> The video splits flawless at the time requ >> >> .dv is a bare bones container and does not support timestamps. Try MOV. I am under the understanding that DV timestamps/timecodes are pretty much the same thing since they use either LTC or VITC on the tape that encodes the date (timestamp) as well as the timecodes, in a “striped” tape anyway. It’s how your deck knows when one shot ends and another begins. So it doesn't support timestamps as metadata but I don't think they are lost, just embedded in the dv stream in a way that’s just a little harder to access.

Re: [FFmpeg-user] Question on Segment TImes
Is there a way to consolidate this to one command?
The goal is to import of DV-TAPE with the best quality in a single pass on the
tape. Sometimes I have go back and parts from FCPX imports. The tapes are old
and sometimes FCPX doesn’t like them.
I was able to get it going with a PIPE: (and 30 experiments on time coding and
segment timing)
export TITLE="284_test"; \
ffmpeg -benchmark_all -stats -loglevel debug \
-c dvvideo -pix_fmt 0rgb -capture_raw_data true -f avfoundation -i DV-VCR \
-c: copy -f dv pipe: | ffmpeg -i pipe: -c:v dvvideo -c:a:0 pcm_s16le \
-strftime 1 \
-copyts \
-timecode "00:00:00;00" \
-increment_tc 1 \
-reset_timestamps 1 \
-segment_time 00:05:00 -f segment "${TITLE}_%H-%M-%S.mov" -y
This yields the following:
bash-3.2$ ffprobe -show_streams -select_streams a 284_test_004_18-00-51.mov

Re: [FFmpeg-user] Question on Segment TImes
OK: That solved the timestamp problem and created a missing stream. Does anyone one know the magic option for getting all three streams into MOV. If I use this to create a DV file (from DVR-DV) it works and creates this file: ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \ -map_metadata 0 \ -c:v copy \ -c:a copy \ -c copy \ -t 10 output.dv -y Input #0, dv, from ‘output.dv’: Metadata: timecode : 00:00:00:00 Duration: 00:00:10.01, start: 0.00, bitrate: 28771 kb/s Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc Stream #0:1: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Three streams If I just change the container to “.mov” ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \ -map_metadata 0 \ -c:v copy \ -c:a copy \ -c copy \ -t 10 output.mov -y I get one stream: nput #0, mov,mp4,m4a,3gp,3g2,mj2, from ‘output.mov’: Metadata: major_brand : qt minor_version : 512 compatible_brands: qt encoder : Lavf58.35.101 Duration: 00:00:10.01, start: 0.00, bitrate: 28773 kb/s Stream #0:0: Video: dvvideo (dvc / 0x20637664), yuv411p, 720x480 [SAR 8:9 DAR 4:3], 28771 kb/s, 29.97 fps, 29.97 tbr, 1000k tbn, 29.97 tbc (default) Metadata: handler_name : VideoHandler I have tried every variation of -map.
