for minimising disk loss you probably can prep. few samples with different encoding/muxing params and burn them all on one disk and see how well/bad your hw player plays (and seeks) them..
Good idea. I tried to burn dv28_Blu-ray.iso to a DVD-R disc with the gui burners Brasero and K3b, but both quitted at start with Failure.
did they show detailed error message?
DVD-R /DVD+R discs Attach log files from the broken DVD-R burning attempts * K3b.log * brasero-session.log
very big thanks. So apparently cdrecord was not patient enough with drive (? unit becoming ready reply from scsi layer) and libburn behind braseo just send something illegal..
I think for now we can limit ourselves to k3b.
Brasero (default) is good for simple burning, but afaik it has no Blu-ray support like K3b. K3b is (more) advanced, but its gui can be somewhat confusing before longer experience.
Suggestion to how customize the previous "CL for HDV to Blu-ray" to burn the now ready made dv28_Blu-ray.iso (with udf included?) and also the BDMV and CERTIFICATE folders to DVD-R/DVD+R and DVD+RW discs?
try growisofs line from manual with this file?
also what "file' and udfinfo/bdinfo says about this iso?
For trying to burn just as data disk - try to drag those folders into k3d and do not forgot to check udf option somewhere (it probably will create hybrid iso/udf 1 fs - not sure if such disk will be seen as avchd by playe.. but worth trying at least once)
Confusing even without BDAV, but "avchd" is seemingly just AVC/H264 - MPEG-4 AVC, while BDMV on DVD media can contain both MPEG-2 and AVC MPEG4 stuff ......? https://web.archive.org/web/20110719224338/http://www.cyberlink.com/prog/sup... <https://web.archive.org/web/20110719224338/http://www.cyberlink.com/prog/support/cs/product-faq-content.do?id=5645&prodId=15&prodVerId=-1>
yeahhh.. apparently avchd spec says about x264 encoded video, and there was (abandoned? ) specification for BLU-ray on dvd media (with wider codec selection?)
DVD+R Broken attempts again with Brasero, while K3b burned the iso image file itself as on HDD. For the latter a selected New Data project and selected the iso file, which maybe was m fault.
is there way to select not New Data Project but 'burn iso image'?
I'll look at and will test more of this next ......
DVD+RW I succeeded to burn the iso file to DVD+RW discs using both K3b and Brasero Playback from HDD with VLC works smootly, from DVD+RW disk a bit stuttered (I/O problems) with short "breathing pauses" at regular intervals (now and then) in video&audio. I expect this has to do with the 25 Mbps bitrate 2.5 x of DVD-video. When I get my ordered BD_RE discs I would expect them to manage this well.
yeah.. from comments on this old blogpost from 2010 people discovered total bitrate on dvd must be not higher than 16-17 mbit/s, and video alone better not to shot over 13 mbit/s. (considering lpcm audio)
Samsung UBD 8500 player still doesn't accept these discs and put them out after saying they are out of specification. I have not compared all format specifications, but these tables cover Samsung FHD and UHD player respectively https://www.easefab.com/instructabletips/samsung-blu-ray-player-supported-fo... <https://www.easefab.com/instructabletips/samsung-blu-ray-player-supported-formats.html> http://www.acrok.com/samsung-blu-ray-player-supported-formats/ <http://www.acrok.com/samsung-blu-ray-player-supported-formats/>
thanks, while those not as detailed as bd specs alone..

so it looks like disk can be detected as bluray of some sort, and our audio encoded correctly...

so yeah, it is udf 2.50!
yeah, from tsMuxer
can you check what udf_test (udf verifier we talked about earlier) says about this disk?
Attach new udf_test.log file
