Audio Visual Application plain Format (BD-R/RE AV) for home video on Blu-ray discs
by Terje J. Hanssen 21 Nov '20

21 Nov '20

Back in 2016/2017 I rendered a 1080i hdv.m2t clip to BDAV, burned it on a standard BD-RE disc and then could playback it as a 16:9 Blu-ray video in a Samsung Ultra Blu-ray player. https://lists.cinelerra-cv.org/pipermail/cinelerra/2017q1/005830.html What I wonder is if also the following features are possible in Cin-GG (bdwrite and/or tsMuxer, ffmpeg tools): According to sources below: 1) The BD-R/RE AV specification accept video captured by an HDV camcorder. HDV streams are already MPEG-2 format so they do not have to be re-encoded to create the partial transport stream and can be directly transferred for recording. 2) In addition to digital broadcasts, BD-R/RE AV incorporates a Self-Encoded Stream Format (SESF) for recording SD analog broadcasts and other material. With SESF, the source video signal is encoded in MPEG-2 (MP@ML) format and multiplexed with its audio (MPEG-1 Layer 2, LPCM, Dolby Digital AC-3), teletex information (PAL option only) and Tip data (video aspect ratio, copy control, coding, etc.) to again create a partial transport stream (see tables). Recording of analog SDTV broadcast and direct DV input in BDAV, is described in the BD-RE_Part3_V2.1_WhitePaper July 2010, page 1, 2, 10-15 http://www.blu-raydisc.com/Assets/Downloadablefile/BD-RE_Part3_V2.1_WhitePa… About BDAV from various background sources: ====================================== BDAV refers to either the transport stream format used for all Blu-ray content, or the plain format intended for home video with no interactivity. BDAV could mean Blu-ray Disc Audio-Visual MPEG-2 Transport Stream or .m2ts The BDAV Container format is based on the standard MPEG-2 TS (transport stream) Both Blu-ray and HD DVD use transport streams, compared to DVD's program streams, to store video, audio, and other streams. This allows multiple video programs to be stored in the same file so they can be played back simultaneously, giving a Picture In Picture effect. The BDAV container with filename extension .MTS or .m2ts is also used in AVCHD format, which is a high definition digital video camera recorder format. AVCHD is a simpler form of the Blu-ray Disc standard with just one video encoding algorithm and two audio encodings. The BDAV container format used on AVCHD equipment is more restricted and can contain only H.264/MPEG-4 AVC video compression and Dolby Digital (AC-3) audio compression or uncompressed LPCM audio. The BDAV container format used on Blu-ray Discs can contain one of the three mandatory supported video compression formats H.262/MPEG-2 Part 2, H.264/MPEG-4 AVC or SMPTE VC-1[15] and audio compression formats such as Dolby Digital, DTS or uncompressed Linear PCM. Optionally supported audio formats are Dolby Digital Plus, DTS-HD High Resolution Audio, DTS-HD Master Audio and Dolby TrueHD. The BDAV container is also used in the BDAV (Blu-ray Disc Audio/Visual) disc format, the consumer-oriented alternative to the BDMV discs. BDAV disc format is used on BD-RE and BD-R discs for audio/video recording The BDAV disc format is the consumer oriented alternative to the BDMV discs made by professional Authoring houses for movie releases. BDAV - a plain' format that is intended for home video with no interactivity. A BDAV disc is basically video on a disc. Content on a BDAV disc is playable on a Blu-ray Disc player from beginning to end. . BDAV was designed in part to provide compatibility between AVCHD digital camcorders and Blu-ray players. It's comparable to the DVD formats used for standalone DVD recorders, DVD+VR and DVD-VR because it's designed primarily for authoring simple Video/Audio content with no menus. What is the BD-R/RE AV format? ========================== http://www.hughsnews.ca/faqs/authoritative-blu-ray-disc-bd-faq/4-physical-l… BD-R/RE Audio Visual (BD-R/RE AV) is an application format designed to record and play back full quality high (HD) and standard (SD) definition digital television broadcasts on BD-R (recordable) and BD-RE (rewritable). It can also be used to capture SD material from analog sources and direct transfers from HDV camcorders. Typically, up to 2 hours of HD material can be stored on a 25 GB single-layer (SL) disc or 12 hours of VHS-quality SD material (double that on dual-layer discs). A basic framework for navigating the recorded material as well as destructive and non-destructive editing is also provided. Occasionally, BD-R/RE AV is incorrectly identified as BD-AV or BDAV. In addition to digital broadcasts, BD-R/RE AV incorporates a Self-Encoded Stream Format (SESF) for recording SD analog broadcasts and other material. With SESF, the source video signal is encoded in MPEG-2 (MP@ML) format and multiplexed with its audio (MPEG-1 Layer 2, LPCM, Dolby Digital AC-3), teletex information (PAL option only) and Tip data (video aspect ratio, copy control, coding, etc.) to again create a partial transport stream (see tables). BD-R/RE AV also accepts material captured by an HDV camcorder. HDV streams are already MPEG-2 format so they do not have to be re-encoded to create the partial transport stream and can be directly transferred for recording by using a standard IEEE 1394 (FireWire/i.LINK) interface. BD-R/RE AV employs a two layer (Clip and PlayList) organizational structure to manage captured audio and video. The Clip Layer is concealed from the user and contains the partial transport streams (stored as clip AV stream files) as well as an equal number of clip information files, each consisting of descriptive details (type, sequence, program and timing) directly corresponding to each stream. The combination of each AV stream and associated information file is called a clip. The Playlist Layer allows the user to view, edit and stitch together clips through a system of playlists (stored as playlist files). A playlist can be either real or virtual and contains one or more playitems, each consisting of a set of start and end pointers to define a range of playback time within a clip. When each clip is initially recorded a matching real playlist (containing a playitem delimiting the clip’s entire playback time) is automatically generated. Real playlists can also be divided or combined by the user and deleting an entire real playlist or segment will erase the associated clip or clip portion from the disc. In contrast, a virtual playlist is always created by the user and contains playitems that point to segments of real playlists. Thus, changes made to a virtual playlist do not affect the original clips so multiple real playlists can be segmented and grouped in any order to form continuous playback sequences. Seamless connection is possible by creating and referencing an optional bridge clip inserted at the edit point between two clips. Virtual playlists also enable audio dubbing to add sound to a clip after it has been recorded. Here, a playitem points to the real playlist of one clip (main path) and a subplayitem to the real playlist of a second clip (sub path). Video from the main path can then be played simultaneously with audio from the sub path. Other BD-R/RE AV features include thumbnails (display images representing the disc and playlists), marks (bookmarks for jumping to specific clip locations, resuming from a location after stopping playback, etc.), naming (assigning titles to discs and playlists), write protection (to prevent modifying or deleting playlists), password protection (PIN required to initiate playback) and others. -------------- Terje J.

Debian 11

Andrew (or maybe other supporters) do you have the possibility to see which packages are necessary for Debian 11 to install Cinelerra correctly? We currently have this ticket still open. https://www.cinelerra-gg.org/bugtracker/view.php?id=536 Unfortunately I don't know enough about the dependencies. I don't want to bother Phyllis in her grief with it. Maybe we can modify the installation routine to show the right packages for Debian 11. Sam

I did little research , and apparently there are some HDMI capture cards/USB 3.0 dongles.

Declink cards require their own SDK (non-free) On windows it seems to be working ... with some effort: https://ianmorrish.wordpress.com/2019/04/02/ffmpeg-with-decklink-support-fo… there was ffmpeg page showing directshow capture on Windows, this lists some 10-bit formats like [dshow @ 0000007201cda8a0] vcodec=v210 min s=3840x2160 fps=30 max s=3840x2160 fps=30 [dshow @ 0000007201cda8a0] vcodec=r210 min s=1920x1080 fps=23.976 max s=1920x1080 fps=23.976 https://wiki.multimedia.cx/index.php/R210 This codec is used in TV & film production and stores raw 10-bit RGB data. Each red, green, and blue color component is 10 bits wide. https://wiki.multimedia.cx/index.php/V210 The v210 format is a packed YUV 4:2:2 format with 10 bits per component. https://trac.ffmpeg.org/wiki/Capture/Blackmagic But you probably need real ultrafast (NVME?) drive for working with those .... at least at higher resolutions.

Ah, there were additional 'formats' in the need of same fixup ....
