The crash is in the FFMPEG encoder, so the code comes from Haiku.

I know Moho looks something not professional... but you can do alot of amazing tricks and animation with it if you know how to do so!

If I start MOHO 2.5 in Terminal I get this message:
Welcome to the Haiku shell.
~> /boot/home/Programme/Moho/Moho [dv @ 0x18863a58] Can't initialize DV format! Make sure that you supply exactly two streams:
video: 25fps or 29.97fps, audio: 2ch/48kHz/PCM (50Mbps allows an optional second audio stream)
Compiler did not align stack variables. Libavcodec has been miscompiled and may be very slow or crash. This is not a bug in libavcodec, but in the compiler. You may try recompiling using gcc >= 4.2. Do not report crashes to FFmpeg developers. Kill Thread

Hello...
Now it renders something... at least Moho is not crashing when trying to render an animation... But the output rendered file is 0KB in size... and so not playable...
But still I got the same output when starting in the terminal...

rendering a file does not crash Moho but still problems with libavcodec maybe...

Will probably be fixed by https://github.com/haikuports/haikuports/pull/2758.

Moho will render to image file like: jpg and png files... all seems to work! ;-)
but still cannot render movie files like: avi/jpeg or mpeg4 files output of the video files is always 0 Bytes
btw. you can download Moho 2.5 at BeShare and try by yourself...

Still Moho renders something but cannot manage to save the file... ...still cannot render animations like: avi/jpeg or mpeg4 files output of the video files is always 0 Bytes I will attach a BeScreenCapture file showing Moho busy render the animation...
But strange Moho 2.5 can render Flash animations! The generated Flash animation can be renamed to animation.swf and be played! I tested with Windows and played the file in Windows Explorer...

Moho is rendering but it seems it cannot save or does not find its path to ffmpeg or save path... no idea how to correct this problem since it is only the binary available. All functions in Moho 2.5 working very well and since it is a native BeOs programm it is very fast and multithreaded. Would be nice if someone could find a solution.

So, the "libavcodec has been miscompiled" part is gone now.
But we still get this:
[dv @ 0x18d29700] Can't initialize DV format!
Make sure that you supply exactly two streams:
video: 25fps or 29.97fps, audio: 2ch/48|44|32kHz/PCM
(50Mbps allows an optional second audio stream)
Which is strange because the list of formats in Moho export offers AVI and MOV, but not DV. Why is ffmpeg deciding to encode in DV, which is obviously not a great choice here?
It seems Moho doesn't really notice the error and still tries to encode something.

Which is strange because the list of formats in Moho export offers AVI and MOV, but not DV. I traced things a bit, and this seems to come from the app (from BMediaFile constructor). So, somehow the list of formats in the GUI does not work and Moho picks some random format? I tried removing DV from the list of formats in ffmpeg and then I managed to get something in the output file, but still I couldn't load it in MediaPlayer. But that's possibly the same problem as in MediaConverter being broken.

I tried to contact the new owner of Moho (https://moho.lostmarble.com/), maybe they will at least answer...

Lost Marble Support posted 10/25/22 4:24 PM I spoke with the dev team and they said they might be able to find the source code for Moho 2.5, but it's uncertain given how old that is (as it came out roughly 20 years ago). But even if they were to find it, they unfortunately cannot release the source code to the public as it still contains confidential code. My apologies.
a software problem maybe
