1. Use one instance of "VLC 2.05 Twoflower" to capture video through BlackMagic WDM Capture device, converting in h.264 and save to ".ps" file.
2. Use another instance of "VLC 2.05 Twoflower" in order to browse through the same ".ps" file, while video is capturing into that file using first instance of VLC.
In general, it works. However, I found some issues I do not understand completely, so I would ask for comments/explanation.
1. If video capturing is performed only, for example without "duplicate" option used for video preview, ".ps" file can not be played from second instance of VLC while capturing is still in progress. When capturing is finished, ".ps" file is accessible for playing.
Please note, that if I am using video device other than "Blackmagic WDM Capture" , like internal PC camera for example, everything works and "duplicate" is not required in order to produce ".ps" file which can be opened and played during video capture process.
In other words following command allows me to open "o.ps" file while capturing:
sout=#transcode{vcodec=h264,vb=2200,fps=25,scale=0,acodec=mp3,ab=128,channels=2,samplerate=44100}:duplicate{dst=display,dst=std{access=file,mux=ps,dst='C:\o.ps'}}
but this command which does not contain "duplicate" option does not allow me to do that using Blackmagic WDM Capture device:
sout=#transcode{vcodec=h264,vb=2200,fps=25,scale=0,acodec=mp3,ab=128,channels=2,samplerate=44100}:std{access=file,mux=ps,dst='C:\Users\x\Videos\o.ps'}
2. "duplicate" option mentioned above does not work completely. It shows one frame only and after that displays many warning messages like:
"main warning: late buffer for mux input (1351878)
main warning: late buffer for mux input (1352753)
main warning: picture is too late to be displayed (missing 1417 ms)"
I would like to use preview if possible. I tried on different computers (X58 chipset and Xeon CPU, or i7 than Blackmagic card over USB3 and directly PCIExpress bus) and I think hardware is not a problem.
Please find log files for both cases. There is some difference in output file creating/handling and I think it may cause issues I mentioned earlier (at least related with question #1)

This is ".log" for situation when playing is not allowed while capturing:
