I am able to render it using some filters. However when I try using Haali Media Splitter with it, video stream is not parsed. Haali would create only audio output pin. There is another MPEG2-TS file(h.264 video and AC-3 audio) which Haali is able to render both audio and video. Can anybody explain this? How can I render first file using Haali?

They?ve recently added MKV support so I can open MKVs directly, edit them and then save as elementary streams or TS and so on. I ran into an issue that we?ve been unable to figure out. On all my systems, the TS file produced is compliant per the VRD developers yet the Haali splitter does not recognize the video stream. Loading the TS file into graphstudio64 only shows the audio pin. If I remux the file with tsmuxer, the resulting file is fine and the Haali splitter recognizes both streams. I?ve uploaded a small sample of the problematic file to mediafire here: http://www.mediafire.com/file/ji8jbhbukiluaja/vrd_clip-001-small.ts. This happens on all my PCs (3) and all run Windows 7 Ultimate 64bit with Sp1 and all latest updates. All use AMD video and two are custom built towers and one ASUS laptop. Please let me know if you need any other info or if you experience the same issue with this file. The VRD developer did mention something about NALs and the file is compliant but I?m not technically advanced in this area and only know basic stuff. Thanks for any help you can offer. A.

The thing is that when playback is running, rarely but often enough to see that it does take place with non-zero probability, streaming does not start after a seek command. That is, an application sets new playback position and from there no video frame is streamed. Playback is stalled until next seek command on the same graph (no stopping, reconstruction etc) which is executed correctly and playback is started from new position correctly as if nothing happened before. Trying different filters in order to possibly isolate the problem, I suspect that it's Haali Media Splitter in asynchronous reader mode, which exhibits the problem. I wonder if it is a known bug or if there is any extended information on this issue available. Thanks, Roman From dave at avpreserve.com Mon May 23 16:51:29 2011 From: dave at avpreserve.com (Dave Rice) Date: Mon, 23 May 2011 10:51:29 -0400 Subject: [Matroska-devel] matroska and process/history metadata tags Message-ID: <3EA50DDD-DB5A-423F-A627-CCB1B158048A@avpreserve.com> Hi all, I'm working in a project that is considering the use of Matroska within a digital preservation environment. One of the goals is to enable the files to be highly self-descriptive noting the relationships to source material (in this case analog tapes digitized to Matroska files), technical aspects of the source material itself, and metadata about the process that created the Matroska file (digitization using which hardware, software, etc). This material is useful when using the content. For instance this data would allow information on the source object, it's condition, and the setup of the digitization process itself to be documented within the Matroska file, similar to how Broadcast Wave Format uses codingHistory. To help enable use of Matroska within video preservation and archival environments, we'd like to propose additional Matroska tags for the following two purposes: - Source Object Metadata: allowing more granular details about the source tape (beyond ORIGINAL_MEDIA_TYPE) - Process Metadata: allowing a description of the digitization process (especially relevant to working with non-file-based source material). To describe the source material, it seems the best use of current nested tags is: ORIGINAL_MEDIA_TYPE - to say "CD" or "Betacam" ORIGINAL_MEDIA_TYPE/BARCODE - to provide the barcode of the source media ORIGINAL_MEDIA_TYPE/LABEL - to document the labeling of the source media ORIGINAL_MEDIA_TYPE/DATE_RECORDED - date original source media was recorded, if known ORIGINAL_MEDIA_TYPE/MANUFACTURER - manufacturer of source media format Since the quality or condition of the source tape affects the resulting file and provides context, these fields could be added: ORIGINAL_MEDIA_TYPE/QUALITY - for qualitative statements about the conditions of the source media ORIGINAL_MEDIA_TYPE/QUALITY/TYPE (example: Physical, Picture, Audio, RF Level, Drop Out Activity) To document the process that created the file we started with a combination of the 'environment' and 'event' metadata structures from PREMIS (http://www.loc.gov/standards/premis/). EVENT="clean, transfer, signal process, edit, physical restoration, etc" EVENT/DATE EVENT/SOFTWARE - name of software used EVENT/SOFTWARE/ROLE - role of software, e.g. capture, edit, driver, operating system, etc EVENT/SOFTWARE/VERSION - version number of software EVENT/HARDWARE - name of hardware used, e.g. playback deck EVENT/HARDWARE/ROLE - role of hardware, e.g. analog-to-digital conversion, playback, processor, etc EVENT/HARDWARE/MANUFACTURER - manufacturer of hardware EVENT/HARDWARE/SERIAL_NO - identifier of hardware EVENT/TRANSFER_METHOD - protocol used to transfer audiovisual data, e.g. composite, component, ieee 1394 EVENT/ACTIONS - description of actions performed within event, e.g. trim silence, normalize EVENT/COMMENTS - notes about the event such as noted errors or untypical outcomes Another approach is to list more fields without the nested structure. SOURCE OBJECT CONDITION (Comments on the condition of the source, any preparation for playback of the source tape, if relevant): Tape had minor exterior damage. Tape was cleaning with an XYZ machine. DATE DIGITIZED (Date and time of the file creation process. Enter in ISO 8601 format): 2011-01-13T19:20:30-05:00 DIGITIZATION EVENTS (Comments about the digitization process including notable time-based events, if relevant): Damage to the source tape prevented digitization of the first ~10 minutes of content ENCODED BY (Name of the technician or organization responsible for the encoding and file creation process): Vendor ABC, Inc. CAPTURE DEVICE SETTINGS (Describe the settings or configuration of the capture device) PLAYBACK DECK SETTINGS (Describe settings of the playback device) PLAYBACK DEVICE MANUFACTURER (Name of the company that manufactured the tape player used to play the tape): Sony PLAYBACK DEVICE MODEL (Model name and number of the tape player used to play the tape): SVO-5800 PLAYBACK DEVICE SERIALNO (Serial number of the tape player used to play the tape): Xyz1234 CAPTURE DEVICE MANUFACTURER (Name of the company that manufactured the A/D card used to capture the digital file): Blackmagic Design CAPTURE DEVICE MODEL (Model name and number of the A/D card used to capture the digital file): Decklink Studio CAPTURE DEVICE SERIALNO (Serial number of the A/D card used to capture the digital file): Abc1324 CAPTURE DEVICE SOFTWARE (Software used to operate the A/D card): Media Express OPERATING SYSTEM (Name and version of the operating system running the computer used to scan and/or process the image): Ubuntu 10.10 PLAYBACK SIGNAL PATH (Protocols used to transfer audiovisual data between the playback deck and the capture device): Component PROCESSING ACTIONS (Description of any actions performed during processing, such as trimming silence) SOURCE OBJECT TRACK CONFIGURATION (Describe the intended audio track presentation of the source object): Four track mono We're sending these notes along for the consideration of the Matroska-devel group. If this initial draft and the scope of the tags used here look okay, then we can document them more formally with definitions and links to external authorities of these terms.

QuickTime and MXF both have features for these kinds of tracks. Purpose: A primary use of a timecode track would be to provide a means to relate each video frame of a related track to a corresponding frame on a source tape (analog or digital) or file. In QuickTime the timecode track has a visual flag (and corresponding font, size, and placement data) so that the timecode data may be overlayed on the video image or shown as data in players that support timecode track presentation (like QuickTime or Final Cut Pro). Additionally timecode tracks (at least in QuickTime) can contain an identifier (aka reel_name or label) to refer to the source material. In this way, multiple source materials could be edited together and frames may maintain an association to the source material by both a frame identifier (timecode) and the source material (reel_name).
