encoding error...

[rkane]

Hi. I’m trying to convert .rm files to mpeg-4.

This is the log I get:

If I change the Target format from MOV to MP4 I think I get the same log:

Any ideas? (By the way, if I want to end up with an AppleTV compatible file would I use MOV or MP4?)

Thanks very much.

ffmpegX has three encoding engines, ffmpeg, mencoder and mpeg2enc. You can see those in the preset list, mentioned behind the target format. Forget about mpeg2enc for now, as that is only used for encoding to MPEG-1 and MPEG-2.

1/ ffmpeg will not encode from .rm sources, as your log #3 shows: unsupported codec.
2/ mencoder will encode from .rm sources, if you also installed the (correct) reallib folder.
3/ the mencoder version in ffmpegX will not encode to iPod/iPhone/AppleTV format.
4/ the iPod/iPhone presets all use the ffmpeg engine.
5/ the h.264 mencoder preset will set the MP4 avc level too high (level 5.1) for AppleTV decoding (level 3.1 max). (The same applies for PlayStation 3 playback.) I consider this a mencoder bug, as the level is always 5.1, and almost always needlessly high.
6/ encoding to h.264 MP4 with x264 ffmpeg allows setting the avc level to any (valid) custom value.
Do you see the dilemma?

A solution would be to encode twice, to create an intermediate format that can be handled by the other engine.
Another solution would be to change the avc level afterwards, but you would need specialty software to do that. I don't think there is Mac software yet to easily make this modification.

So, encode your .rm first with e.g. XviD mencoder preset (fast with decent quality). Use a very high bitrate to limit generation quality loss. It will be a big file, but you won't keep it, so that doesn't really matter.
Next, encode the intermediate file with the iPod h.264 640w preset. Modify the video size if you want, but keep within AppleTV specs. Re-optimize the bitrate if you changed the video size, as bitrate depends on frame size.

H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

Thanks, Case. I’m new at this so you may have to bear with me a bit.

I switched the encoder to XviD [.AVI] (mencoder) and it failed. I'll paste the log below.

What would you recommend for a high Video Bitrate?

Thanks very much for your help!

If you downloaded the reallib from the ffmpegX website, it is unfortunately still the PPC version, which is not MacIntel compatible.
Back in April 2008, user jpschuck taught us how to get the Intel version of reallib:

1/ There is an Intel version available at the Mplayer official website. Look for the "Binary codec package" section and choose "Mac OS X x86 20060611".
2/ Once the 11.5 MB download is completed, double-click the package in order to install it ; this will install the required codecs and enable RealMedia playback in Mplayer for OSX, but not yet for ffmpegX.
3/ Under the Finder choose menu "Go" > "Go to folder..." , type /usr/local/lib and hit return; this will open a hidden folder. One of the items should be a folder called "codecs".
4/ Open a new Finder window. Goto /Library/Application Support/ffmpegX/". Delete the old "reallib" folder (if present).
5/ Copy the "codecs" folder into "/Library/Application Support/ffmpegX/" and rename this "codecs" folder to "reallib".
6/ Now ffmpegX should be able to deal with RealMedia files. Test it by dropping an .rm file onto ffmpegX, then use the Play button. Press 'q' to quit mplayer.

What would you recommend for a high Video Bitrate?

Double it.

Thanks so much for your help, Case. Unfortunately it didn't work. This is the log (and I'm also attaching a screen shot of a few things).

<<ffmpegX 0.09y screen shot .pdf>>

Thanks for the screenshot. Rename the folder "reallib" (two "l"s).

[rkane]

That did it! Thank you (although after re-reading an earlier one of your posts I realize that I did the final encoding with the wrong preset: I used .MOV instead of the iPod h.264 640w preset, which I'll try next).

Again thanks very much for your help.
