avc2avi Problem

[ONeill]

Hello,

i want to convert a hd trailer which is put into an mkv container to an avi file.

I extracted the video file ( h264 ) and the ac3 audio file.

Now i used the avc2avi.exe programm to convert the h264 file to an avi file.

But this part goes wrong. the file which the programm creates is broken/invalid.

What could be the reason,because the program is very easy to use.

Thanks for help

Are you at least sure the extracted h.264 raw stream isn't corrupted already ? And thanks to what did you see the generated avi file was corrupted ? Gspot ? Avinaptic ? It didn't play in vlc/mplayer/mpc ?

Doesn't avc2avi leave an error/status message indicating something relevant ?

You could use ffmpeg for this purpose too I suppose :ffmpeg -fps 25.0 -i "whatever.264" -vcodec copy -f avi "whatever.avi"
I don't have a clue if it'll really work though (and I'm too lazy to try it now, but if it does, don't forget to change -fps to whatever it should be).

Hello,

i can play the Source h264 file and GSpot can also open it, so the file should be correkt.

The converted avi file couldn't be player by any player and also couldn't be opened by GSpot, so i think the file is corrupt, allthough the file size is correct.

avc2avi doesn't show any error message. It seems to work correctly.

Any other ideas?

I will try ffmpeg too now.

EDIT:

I tested the conversion with ffmpeg. The file seems to be a bit better. GSPot can oben it and recognizes the file. The codec is correct, but it says that there a 500mb unused data at the end of the file. So that it is not everything correct.

what do you want to do with the avi, you cant do with the mkv? maybe there is a solution by keeping the original file..

[ONeill]

OK,

i want to use PowerDVD for Playback becaus PowerDVD usere my Graphic card for acceleration.

I couldn't figure out how other programms could use my graphic card.

I am new with this topic, and maybe there is an other way to play my HD files with the support of my graphic card.

Thanks for help

try the mp4 file format, if a format is supported its either mp4 (or evo from hddvd)

[ONeill]

Which Program can I use to convert my mkv file to a mp4 format.

EDIT: I found a tutorial. I will try this way: http://www.winfuture-forum.de/index.php?showtopic=94669

Thanks for now :)

MPC (Casimir) + EVR + Cyberlink H264 Decoder = GPU accelerated.

[ONeill]

Hello,

what means Casimir and EVR?


EDIT: Ok, found it. Thanks for that hint.

[Sirber]

from my testing, Cyberlink don't decode all my H264 sources. :(
I sometimes get black screens and no playback.

[ONeill]

You are right. With the Casimir build my HD Videos are running perfectly. Thanks.

But now i have to solve the Problem that mpc has problems to put the audio out of spdif to my decoder.

@ONeill: The MatroskaSplitter-package includes a simple command line program called: "mkv2vfr.exe" which converts mkv-files into avi-files. The limitation is that it only converts the video-track. Therefore you will have to use e.g. VirtualDubMod to mux an AC3-track into the AVI-file. I am using this for DVB-S2- satellite recordings of H.264/AVC-AC3-tracks. The resulting H.264/AVC-AC3-file plays perfectly using Core-AVC-Version 1.1-video codec, AC3-Filter and Haali-splitter und my Sony SZ-laptop with a Core 2 Duo T5600 processor at full frame rate and about 45-65 % processor load.

[ONeill]

Oh, i will try that allthough my mpc plays the mkv with hardware support.

Thanks for that hint

Hello Sirber,

i got the same Problem. Black Playback, only audio with some files.

Are there any fixes for that?

[ONeill]

Another thing:

I testet MPC today with EVR and PowerDVD Decoder but at some points the movie stops for a short time and afters that the sound isn't right anymore.

What options do i have to set to make the movie play well?

My PC:

P4 3,4GHz
2GB DDR2-Ram
NVidia 8600 GTS

should be fast enough to play a HD video, right?

Thanks for help

Considering the h.264 decoding is done via your GFX card, I wouldn't say the CPU is choking (it should hover under 30% in your case).

Anyway, since your file couldn't be re-muxed properly with either ffmpeg or avc2avi, I suspect your file is broken in the first place. Some broken files also have the audio sync come back gradually sometimes (like it takes 2 minutes for the audio to catch the video up again, or vice versa).

Would you mind telling us where you got the trailer ? Or upload it somewhere for us to check ?

Also, how does the decoding work without GPU acceleration (through vlc for example) ?

[ONeill]

@Dark

Yes, you are right. My PC works with about 30% by playing the HD file. Allthough, the file somteimes chokes.

I tested avc2avi again and it worked partialy, because mplayer couldn't play it, but vlc could play the file. VLC says that the file is broken and the programm would fix this. Denying that, the file is played normaly, but without a navigation bar.

I tested avc2avi with two other files with the same result.

I played some other files and they seem to run smoothly, but they all have got ac3 soundformat and NOT DTS like the file which doesn't work right.

Could that be a problem, that my audio decoder is to slow/bad or something like that?

Or something in this direction?


EDIT: I was wrong. I tested some other HD files with AC3 Sound with the same result.

I think that i configured the MPC wrong. VLC doesn't play the files as good as MPC, but also quite good. They choke after some time with both programms. The image quality is better with mpc.

Is it right, that the ffdshow symbol is in the taskbar, allthough i want to use the PowerDVD Decoder? What settings do i have to use with MPC?

Thanks for your help again :)

Use the modified version of AVC2AVI from there: http://sourceforge.net/projects/avc2avi

Split the AVIs at 2000MB and join them in VirtualDub afterwards. AVC2AVI breaks AVIs with size over 2047MB.

Hello, I have s serious problem which I do believe is caused by AVC2AVI. I tried to convert a h.264 stream from AVCHD (TS/H.264, 1080i PAFF) to AVI. Unfortunately after conversion the video reports everywhere it is only 1440x540 (instead of 1440x1080). I believe there is a problem with support of interlaced streams.

[Schmendrick]

Hi vlada,
you still seem to use an old version of avc2avi. The version posted just one post above your post fixes your problem. Somewhere there also is an avc2avi_gui in case you don't like command line programmes.
