Another error message

[Dr.Doolittle]

I have a bunch of small divx files I am converting back to mpeg2 for burning onto DVD. With the previous version of ffmpegx, using the High Bitrate DVD (NTSC) quick preset option worked flawlessly. After upgrading to 0.0.7 with the same settings, I get the following message in the terminal:

**ERROR: [mpeg2enc] Input stream with unknown frame-rate and no frame-rate specified with -a!
**ERROR: [mpeg2enc] 3:2 movie pulldown not sensible for NaN fps dispay rate

The audio then goes on to encode, but I'm left with no m2v file. I checked the framerate setting (NTSC FILM), it matches the framerate of the divx file.

Any ideas?

Could u email me your exact settings and I will check.

I get the same error (**ERROR: [mpeg2enc] Input stream with unknown frame-rate and no frame-rate specified with -a! ) when using the VCD (NTSC) preset to convert DIVX files. Terminal finds an error, skips the video part but processes the audio.

0.0.4 seems to work fine (the only backup I had! Are the 0.0.6 versions archived anywhere?).

[major]

There is indeed a small bug which breaks the process in some cases for .avi to mpeg-2. I'm fixing it to 0.0.7a to be quickly released.

I thought I had everything installed correctly but in 0.0.7 get a nice error message after a .mp2 file is created (now i can listen to the whole movie)

**ERROR: [mplex] Unable to open file /Users/donna/Desktop/cuckoo/gavin.m2v for reading.

It has not created a m2v file .. but an mp2

only the audio, no video. I'm lost.

I am using a 400 mhz G3 iMac running only 10.2.6 (no 9) and I am running out of HD space and I'll try again when the new HD arrives but....
I was converting a home made vob to SVCD on presets. The video on question is about 45 minutes long.

any help is appreciated.

This error means indeed that the .m2v file has not been created. To know why, you should look for another error at the beginning of your terminal output.

hi all,
i have the same error message, what's wrong?
please help me.
bye lars

/usr/bin/mpeg2enc: invalid option -- h

that could be an issue with the latest mpeg2enc,
disable "Encode hi freq" in the options tab and see if this works
