Hi, this updates the sizes of the fisbone ogg_packets after the removal of the x- prefixes. Not tested, don't have ffmpeg on this machine, but compiled nonetheless :) Cheers -------------- next part -------------- A non-text attachment was scrubbed...

It's well possible there are bugs. I don't know when the code was last updated. Also, I am not sure if there are command-line parameters to set the role - I would think there are. I don't actually have these tools in use right now, sorry. I hope somebody else can help. Silvia. On Sun, Aug 24, 2014 at 5:21 PM, Nick Burch <ogg at gagravarr.org> wrote: > On Sat, 23 Aug 2014,

Hi everybody, I've updated OggIndex to now output Skeleton 4.0 tracks. The differences between Skeleton 3.x and Skeleton 4.0 with OggIndex is: * The fisbone packet now includes a "Radix" field. * The fisbone packet now includes two new compulsory message headers; "Role" and "Name". * The fishead packet no longer includes "start time"

I've developed an indexer which embeds a keyframe index track in Ogg files. It embeds the index in its own track, so that players that don't understand or don't want to use the index can just ignore it. Ogg needs this to make seeking over networks faster and more efficient. Currently we must do a bisection search when seeking, which usually takes aound 6 HTTP requests, give or

Hi, What are the two granule rates in a fishead packet supposed to be for ? Since each of the streams has a corresponding fisbone packet with its own granulerate in it, and they can be all different, wha does the presentationtime num/den means ? Also for hte basetime num/den, since the UTC time which is also present in fishead seems to be a textual representation rather than a linear count ?

Hi, in a follow up mail with Conrad, I was wondering whether Language-Category would be conflicting with any "standard" namespace, and he suggested I ask on ogg-dev, where people (*cough* Silvia *cough) might have a better view of how to use those. He mentioned the possibility of using X-Language-Category as well. Essentially, I'm not sure if the choice for those fields has any

Oh, sorry, I completely misunderstood. You want to make them time-parallel streams! I would merge them with oggz-merge without skeleton and then add skeleton using oggindex e.g. http://git.xiph.org/?p=OggIndex.git;a=summary . (oggindex is also available from http://firefogg.org/nightly/ ) Hope that helps. Silvia. On Sat, Aug 23, 2014 at 3:35 PM, Nick Burch <ogg at gagravarr.org> wrote:

I've gone ahead and raised three bugs, one for the offset, one for more helpful error messaged, and one for subsequent streams of a given type needing different roles+names.

Hi All I'm currently trying to put together an ogg file with two theora streams, a handful of audio streams (probably mixed vorbis and opus), and a Skeleton stream that describes their relationships to each other. I had hoped to be able to use the oggz suite of tools, but I can't seem to get that to work. To generate my theora files, I'm using ffmpeg2theora, which will happily

...html [1] RFC3533: http://www.ietf.org/rfc/rfc3533.txt New in this release ------------------- The hogg tool contains new subcommands: sort, selfcheck Improved handling of Ogg Skeleton tracks in chop, merge and rip subcommands: * merge: Ensure that the output contains only one Skeleton track. Fisbones from Skeleton tracks of second and subsequent files are copied into the first Skeleton track. * chop: Handle rewriting of Skeleton when chopping files which already have a Skeleton track. Ensure to re-use the existing track serialno and metadata, but rewrite the presentation time...

[cc'd to ogg-dev] Hi Tahseen, thanks, I've checked and applied this patch to liboggz svn (rev 2378): http://trac.annodex.net/changeset/2378 Two requests for further patches: 1. could you please document the -k switch in the --help output, and in the man page (doc/oggzinfo.1.sgml) 2. there's some extra newlines between the info for each track, could you try cleaning that

Actually, we have been discussing this kind of addressing for a very long time and it was half the point of the Annodex project (see www.annodex.net). What we have defined for addressing is the following: * temporal addressing: http://annodex.net/TR/draft-pfeiffer-temporal-fragments-03.txt Any ogg file can be addresses through temporal offsets. This goes across different logical bitstreams. *

What is Language-Category being used for? Conrad mentioned HTTP headers, which is where the naming scheme for Skeleton came from. Is there any fields in the HTTP headers that would be more appropriately named for your needs? Also, the "X-" naming will make it really safe, because you can choose those at will. The others are more "standard"... Cheers, Silvia. On Mon, Jun 16,

Hi, I've seen several implementations of Ogg demuxing that use a zero granulepos to detect headers. However, I do not recall seeing this in the Ogg docs - is this an abuse that happens to work because Vorbis is timed by end granule, or is it a proper way to check ? Thanks

Ralph, Conrad, Now that we have ROE as a means to describe a multi-track ogg file - i.e. a means to author Skeleton - I assume this is supposed to describe how we map ROE information into Skeleton through the use of fisbone message header fields, right? In this case I wonder if you have gone over all the current ROE spec and made sure that all this information is either in ROE or easily
