It's not very clear to me, what I'd like to understand is that if using Matroska I will have a lower overhead on a h264 + aac. At the moment I notice that on long videos, aourn 1h:30m the overhead needed by the mp4 seems around 1.5 Mb. thanks again From steve.lhomme at free.fr Fri Oct 19 10:50:10 2007 From: steve.lhomme at free.fr (Steve Lhomme) Date: Fri, 19 Oct 2007 09:50:10 +0100 Subject: [Matroska-general] MKV vs MP4 In-Reply-To: References: <47179F6B.7030909@alexander-noe.com> Message-ID: <47186FC2.7070808@free.fr> Emanuele Fumagalli wrote: >> Emanuele Fumagalli schrieb: >>> Hi all, >>> I'm evaluating Matroska to use it as a container instead of MP4. >>> What I'm looking for is to reduce as much as possible the header that >>> is loaded before decoding the video and audio streams, >>> that's because I intend to stream the file using a progressive download. >>> Do you know if Matroska can have a more little header compared to MP4? >> You can find an overhead comparison here: >> >> http://www.alexander-noe.com/video/amg/en_overhead_comparison.html > > Hi, > thanks for answering and for the link. > > It's not very clear to me, what I'd like to understand is that if using > Matroska I will have a lower overhead on a h264 + aac. > > At the moment I notice that on long videos, aourn 1h:30m the overhead > needed by the mp4 seems around 1.5 Mb. IIRC MP4 sucks for streaming because you need some information that are usually at the end of the file. Matroska doesn't need any information that are usually at the end of the file (like seek info).

Actually there's a way to have all the header at the beginning in MP4, what I'm evaluating is the overhead needed from the decoder to strart playing a video. I made a quick test and it seems that using MKV I can save 50% of the header size, but I son't know why. Is there maybe some option in Matroska to compress the header even more? thanks for any help bye From steve.lhomme at free.fr Fri Oct 19 12:32:51 2007 From: steve.lhomme at free.fr (Steve Lhomme) Date: Fri, 19 Oct 2007 11:32:51 +0100 Subject: [Matroska-general] MKV vs MP4 In-Reply-To: <7F15BE70155B4929B0A8FB453EEE000C@emanuelePC> References: <47179F6B.7030909@alexander-noe.com> <47186FC2.7070808@free.fr> <7F15BE70155B4929B0A8FB453EEE000C@emanuelePC> Message-ID: <471887D3.8010906@free.fr> Emanuele Fumagalli wrote: >> IIRC MP4 sucks for streaming because you need some information that >> are usually at the end of the file.

Not really. It depends on what program you use to mux. For example mkvmerge leaves about 4 KB of data at the beggining in case it needs to write some more stuff later. Usually this space is not used. So modifying mkvmerge might allow saving a little more space. Other muxers may have similar things too. I think AVI-Mux GUI (from Alex No?) is the most flexible for that.

The header size is about the same for all matroska files. It should be around a few KB (between 4 and 8). That excludes seeking, which is pointless if you're just streaming, which is usually put at the end anyway.

That excludes seeking, which is >pointless if you're just streaming, which is usually put at the end anyway. actually I would like to use it for a progressive download, so letting the user be able to see the video while downloading and also perform seeking. I already do that with an mp4 container and I was wondering if using matroska I could have some advantages like smaller header at the beginning.

There are 2 ways of seeking in matroska. The Meta-Seek which just seeks among the level 1 elements, in your case the clusters (usuallya big packet of a few seconds of audio/video/subs). This one takes a very small size and it's usually included at the beggining. But it is not efficient for frame-accurate seeking. For that there are Cues which keep a reference of all video (or audio sometimes) frame timecode to locate them faster. You may add that too to your file depending on how accurate you want your seeking to be. It takes a little more space in the file, maybe a few 10 KB and can be placed at the beggining too.
