.h264 to avi?

[Snowcrystal]

Hi,

I have extracted a mkv file which contains an .ogg and a .h264 file.
I've tried searching everywhere including here but I couldn't find a way to convert the .h264 file to avi. If it was a mp4 I know how to do it but the extension is .h264.
Virtualdub couldn't open it. I've tried mediacoder, but the whole thing collapses as soon as I hit the start button. I just to play on my standalone dvd player.
I need some help please.

thank you

alltoavi?
super?


but if it contain h264 vfr you will probably get sync problems...build a htpc!

If you really must do it. Use avc2avi. Can't see the point though. Nothing really that will play AVC in an avi that can't play it in an mkv.

[Baldrick]

i think he wants an avi with divx or xvid....so it works on standalone divx,xvid player...

First of all you'll have to recompress the whole thing.
When alltoavi fails here is how's you do it.

You feed the mkv into vbubmod though an avisynth script like this

DirectShowSource(fps=23.976,"MkvFileHere.mkv")

Use vdubmod to convert the ogg streams into mp3 and again to mux them with the avi and the're ready.

One small glitch - which i haven't figure how to solve yet, but doesn't happen to all mkvs - is that in some mkvs is you do this, the video gets desynchonized with the audio. You can try matching the framerate of video to audio, that works.. sometimes.
Good luck.

That would be due to VFR video.

DirectShowSource("MkvFileHere.mkv", fps=119.88, convertfps=true)

No more sync problems.
The reason for 119.88fps:
119.88 / 23.976 = 5
119.88 / 29.970 = 4
So in the above example the source is hybrid 23.976/29.

@Snowcrystal: You should have either ffdshow or even better PowerDVD7 installed (demo version is sufficient) in order to be sure to have an AVC/H.264-decoder on your system so that there is a directshow decoder to decode the h264-video. Sometimes some H.264-video cannot be properly decoded by the ffdshow-decoder. The cyberlink decoder included in PowerDVD7 usually is a better choice.

Thank you for you replies. I finally found a way to convert it using winavi.
I've tried super but it didn't work, I've got an error with it. I could convert it using alltoavi but the videolenght got all messed up. Finally I've tried winavi and this time no sync or videolenght problem .

Snowcrystal how do you convert it with winavi

[Snowcrystal]

I've used winavi 7.6 and just add the mkv as a whole and select xvid codec, adjust the bitrate and in my case make sure bitstream, qpel and gmc are disabled and hit the start button. I've never thought it would be this simple, because I've tried many converting softwares but none has worked before.

What error did you get in SUPER, by the way? It usually tries to tell you how to resolve the error... it could be as simple as un-checking the "Use DirectShow" box.

snowcrystal when you encoded does it detect the subs if it has any
