MKV in H264???

[magnu]

Can someone tell me how I can find out if an MKV file is in H264? I've tried MediaInfo GUI, but cannot find any reference to H264 in any files, including those that are in that format?

[Meritocracy]

H.264 = AVC (Advanced Video Coding)

You'll see the latter under Format and Format/info in Mediainfo.

@magnu, You have got it reversed. H264 is the type of compressed video stream, and it would exist raw (elementary stream) or contained in a multimedia container, like avi, mp4, mov or mkv. You wouldn't have a container contained within an elementary stream.

I'm aware the title is actually reversed. I just couldn't think of how to write the title down, so it was the first that came to mind. What I'm basically after is how to know if an MKV is actually H264, or if it's only been created by something like MKV Merge, or similar software that doesn't compress.

What Meritocracy told you was correct. If you look at the MediaInfo "FORMAT" field (usually 2nd) in the Video Stream(s), it will show you "AVC" (although occasionally it will use x264 when that codec library is used).

I've never seen an MKV file that said it was made with something other than mkvmerge

Once a program encodes the video/audio, it uses MKVmerge to mux those streams together into an MKV file

MKVmerge doesnt encode, but its always the final step in making an MKV, because its the tool that places streams in an MKV

does that make sense?

What about AVIMux-GUI?

havent come across a video that says that was the writing application tbh

either avimux gui uses mkvmerge to do its muxing for mkv

or I just coincidentally havent seen an MKV that used avimux, if avimux is independent

[poisondeathray]

it's offtopic , but haali muxer (gdsmux) will write the metadata and writing application, an alternative to mkvmerge

[DrDeceit]

eh, I wasnt implying mkvmerge is the only one in existence

my POINT was that mkvmerge is most often used to write MKVs, but that doesn't have any effect on the streams inside the MKV

[poisondeathray]

Yes, I know the point you're trying to make .

(But technically it's not correct, both mkvmerge and gdsmux do have an effect. Both will remove sequence headers from a raw avc stream - this has no impact on visual or audio quality, but it does have impact on some applications like some professional blu-ray authoring programs which will reject the streams once it has been touched a mkv muxer)

I can split hairs too >_>
