It creates empty files!

[aquasonic]

Why does it tell me that the file has been created but when I check the file - it's zero KB in size?

I'm trying to create FLV files, but I have also tried to convert to other file types - but it always creates an empty file? It creates the file in about 1 second?

Can anyone help me with this???

The encoding failed. Please post the log to let us help you find out what went wrong and how to fix that.

Audio is listed before video, which is inverted from what the encoding engine wants. Check the Invert mapping checkbox in the Audio tab to tell ffmpegX how to deal with that. Then try encoding again. That should fix things.

Sorted!

a similar thing happened to me while converting flv to mp4. here's the log:

a similar thing happened to me while converting flv to mp4.

So much similar, that the same fix should be applied.

[bsmity]

I am having the same problem and tried with and without the Invert Mapping checked with the same results, my file is converted in a about a second and the file size is 0k.
Any suggestions to this dilemna?

The double audio stream is causing trouble here. If you have QuickTime Pro, then try deleting one audio stream, save as a new copy, then convert.

Not sure why I am unable to access the video file, I have changed it from the long name to a shorter name just in case. I still am unable to create my file for my ipod.

Ok I had the same problem as the first post and I followed the instruction to select "invert mapping" in the audio tab. Doing so created a flash movie rather than an empty file but it plays back at about 2 frames per second no matter how the video settings are set. I took the exact same file and reversed the order of the audio and video tracks in Quicktime pro by extracting, deleting and then pasting the extracted audio back. I then deselected the "invert mapping" button and it made a movie that played just fine.

Is there an error with the "invert mapping" function that is leading to this? I was going from MPEG 4 to FLV and reducing the size from 640X480 to 320X240 and the frame rate to 15 Fps from 30.

Is there an error with the "invert mapping" function that is leading to this?

I don't think so: the stream mapping itself is working fine. There are some other odd thing here, tho'.

Your good encode has different source bitrate, different source video codec, different output framerate, different output video size. You changed more than the stream order, it looks like a re-encode, which makes comparison more difficult ("apples and oranges," as they say). That alone doesn't account for the 4x more video data, tho'. Quite odd.

Try Decode with QT in the Option tab, to see if that helps getting better/smoother playing output.
If route #1 (default settings) won't bring you desired results, then try route #2 (change some setting, like Decode with QT).

[Plisko]

Wow. . I tried to re-encode the same exact thing with the same settings as the other file to try repeating the error. I can't believe it was that far off. I may have accidentally used the wrong file or grabbed the wrong log. I'll see if I can repeat this again in the morning using the same exact file.

[pixelgeeek]

I've tried the invert mapping solution above and no luck.. still zero K files. I'm trying to convert an MP4 to flv. Log below... The last line mentions a codec mismatch... any help would be greatly appreciated. Pixelgeeek

Thanks! It converted the file, but it is very choppy. Will that have to do with this process or the quality of the original file? Thanks again, Pixelgeeek
