CUDA don't work, why?

[lovelylisa]

I downloaded and installed 4Media MP4 Converter 6 from giveawayoftheday and it has CUDA support.

During install, it detected CUDA and enabled it because I have a Nvidia GeForce 8400M GS graphic card in my HP notebook.

And according to my video card specs, I should have 16 CUDA cores:

http://www.nvidia.com/object/geforce_8400M.html

But when I encode files, CUDA is not working, even though it says it's "ENABLED" and it even blinks during encoding to show it's working. But the encoding takes 30 minutes with or without CUDA enabled.

Why isn't it working?

According to their website, it should be a lot faster with CUDA enabled:

Any ideas please?

Maybe it's a scam. The blinking light sounds fishy.

What CPU are you using? The 8400M is the bottom of the CUDA barrel. Maybe it's just not any faster than your CPU? Try MediaCoder. And I find CUDA encoders still give inferior quality.

I can't use MediaCoder because it doesn't support importing my .TS files and encoding them into MPG.

And if CUDA don't work on 4Media MP4 Converter 6, then maybe it won't work on MediaCoder either. Maybe I need to upgrade my CUDA drivers?

[aedipuss]

considering that a current nvidia desktop card has 300 to 500 cores running 10x faster than your mobile gpu, it's not surprising it isn't faster than your cpu.


stick with handbrake, xmedia recode, mediacoder, etc. they all give better results like jag said.

Couldn't see any information regarding that applications "cuda" support ... might have been a pipe dream.

You should check your installed video driver package ... a few things work better using the beta 182.05 drivers for that gpu.

Cuda encode is format limited.

Under Device Manager in Vista, it says I am using nvcuda.dll version 8.16 .11.8766 - 03.10.2009

So where do I get the beta 182.05 drivers?

And if CUDA don't work on 4Media MP4 Converter 6, then maybe it won't work on MediaCoder either.

But several people here have used MediaCoder and its CUDA option so we know it works. Try remuxing your TS file to MPG?

Why don't Mediacoder support importing ts files?

And how do I remuxing the TS file to MPG and keeping sync?

And as topic says... how do I get CUDA to work in 4Media MP4 Converter 6?

[jagabo]

I was able to import a TS file into Mediacoder.

I don't think anybody here uses 4Media MP4 Converter.

Yes, I got TS importing now. But I have a problem. I tried H.264 in "video" format and it encodes a 30 mins TS file into a 9mins MPG file and a 60 mins TS video into 20 mins MPG file. How come? What happened to the remaining 21 mins and 40 minitues? Why is MediaCoder truncating my files and making them shorter? The original TS files play a lot longer than the resulting MPG file. Is this a bug?

[Nelson37]

Source of TS files?

Results of using a different encoder? Even the El Cheapo POS that nobody else has ever even heard of? I'm curious, what the hell induced you to try something that they have to promote to give it away for free?

Results of same encoder with NO Cuda used?

Detail on encoded portion of TS file - Exactly where is the cutoff? Tried editing the file past that point and encoding the rest? Is the file speeded up? Is the audio there? Is the cut off at or near an edit point or file playback error?
Results of using only audio, and only video? Tried Demux/Remux?

It is possible this is a bug, but it is a near certainty that there is some error in the file or procedure.

I live in Sydney Australia and using a MobiDTV USB TV Stick to record TV using NextPVR which saves the TV shows into .TS format.

CUDA don't work and nobody can tell me why. And I cannot use MediaCoder either because it trunctuates my files for some weird reason...e.g a 60 mins show is trunctuted into 20 mins etc.

I suspect there is a discontinuity in the TS file. A change of resolution or a time code break? Does the truncation happen right at an ad? Try using a different source filter in Mediacoder.

It doesn't happen at ads, it just happens in middle of show.

But VideoRedo encodes the whole file to completion and the resulting MPG plays fine. But I want to get MediaCoder working because VideoRedo trial will expire soon.

What different source filter in Mediacoder do you suggest? Because I already tried a few of them.

Maybe MediaCoder encounters a certain amount of frame errors and just stops encoding? Could that be the reason? But as I mentioned earlier, the TS files encodes fine in VideoRedo.

What is VideoRedo succeeding to do, that MediaCoder is failing to do?

[Nelson37]

VideoRedo is designed to do some file repair where MediaCoder is not.

Running it through another editor, and/or demux/remux, will often solve these types of errors.

[jagabo]

Try remuxing the file with something like TsMuxer or Mpg2Cut2. Several other TS muxing and repair tools are mentioned in this thread:

I have tried many different programs, but they all end up out of sync. But VideRedo works great.

What editor/demux/remux do you suggest before importing it into MediaCoder?

I imported the TS file into TsMuxer and it said some tracks were not recognized and were ignored, whatever that means and I selected TS muxing as output. And then I remuxed to TS and imported the new TS file into MediaCoder, but then MPG it created contains NO Audio.

What now? Why did TsMuxer rip out the audio?

[jagabo]

Why did TsMuxer rip out the audio?

"Some tracks were not recognized". Try another file from your source to see if it's not just that one file. If it's unable to handle the audio in all your files you'll have to try another program. What type of audio is it? MediaInfo will tell you.

Some are AC3 and some are MPEG audio.

Try using freemake video converter instead ... and its recommended having a gpu with 96 cuda core's for real performance improvement

Mines the gt 420m (laptop) ... now a dvd to h.264 has dropped to 13 minutes ... 300% improvement over my old rig which took 45mins or longer

I tried using freemake video converter, but the MPG files play out of sync where the sound come before the lip movements. That doesn't happen in VideoRedo.

And also, a 60 mins TS file only takes around 3 minutes to encode to MPG using VideoRedo, but the same file encoded to MPG using freemake video converter takes over 40 mins. WHY?

[jagabo]

I tried using freemake video converter, but the MPG files play out of sync where the sound come before the lip movements.

If it's a constant offset you can easily fix that by adding an offset when you mux.

And also, a 60 mins TS file only takes around 3 minutes to encode to MPG using VideoRedo, but the same file encoded to MPG using freemake video converter takes over 40 mins. WHY?

Probably because VideoRedo isn't encoding the video, just remuxing it. Whereas Freemake Video Converter is reencoding it.

1. How do I fix it by adding an offset in freemake video converter? Where and how?

2. So that means I cannot use freemake video converter because it's not smart enough to just remux the TS to MPG and it reeondes the whole file which is a pain. Because VideRedo can take 3 minutes to make an MPG but freemake video converter takes over 40 minutes to do the same file. That's crazy!

Is there a way to tell freemake video converter to remux the file to MPG and not reencode the whole file?

[DarrellS]

I wish someone could figure out the command line argument to get CudaH264enc.exe to work with the external encoder feature in Virtualdub 1.10.0.

Here is an argument for x264.exe...

--crf 21 --preset medium --tune film --demuxer raw --input-csp i420 --input-res %(width)x%(height) --fps %(fpsnum)/%(fpsden) -o "%(tempvideofile)" -

Try using ProjectX or PVAStrumento to correct your .ts files before loading into another editor/encoder. You WILL need to find and follow the guides for both of them as they're not particularly intuitive but they were designed for just the problems you've been seing. As for your CUDA probs, weren't there problems with the nVidia 8??? cards and CUDA? I'm sure that's why I went for a 9600GT over a 8600 or 8800 card a few years ago.

[jagabo]

I don't know the program. I was just giving general advice. Most muxing tools allow you to specify an audio delay or advance (negative delay).

ProjectX don't work as it produces a full lenght video file but a shortened audio file. For example, a 60 minute video running through ProjectX produces a 60 minute video file, but only a 20 minute .AC3 file. Any ideas why it does that?

And when I run the TS file through PVAStrumento it produces 2 files, an .mpa and .mpv.

What do I do with those 2 files now to create an MPG?

.ts files often have transmission errors in the audio, the video, or both. The shortened audio file from ProjectX could be the result of audio errors. Maybe the ProjectX log can tell you what happened.

.mpa is audio .mpv is video. You need to re-multiplex them for an .mpg. ImagoMPEG-Muxer might work.
