Video recording script for FFmpeg

[KTM57]

Do you still suggest using huffyuv/libx264, and ac3? I have trouble with playback and can't find the fix that I used on my last installation of windows.

Those codecs work well for me, but if your software has trouble with it there are lots of other codecs to choose from. "ffmpeg -codecs" will list them.

when I open the mxavi from the ffmpeg4mxsim folder, it instantly quits, and yes I followed all the steps correctly, then when I try and open it with the command prompt, this is the error I get. [img]1olz4y[/img] http://prntscr.com/1olz4y

Looks like you dragged mxavi onto ffmpeg.

I dragged in ffpmeg then typed ``mxavi``

OK. Not sure where it says to do that in the instructions...

Im just troubleshooting, Nothing is working. Idk how to right the path for it, so I drag it in to auto do it for me

Nevermind I got it to open, I can open mxavi and play the demo, but when I close mx sim and then close mxavi, no videos are there... Any help?

I am getting an error when I quit the game. Sometimes it works and sometimes it doesnt, when it doesnt I dont end up with the video afterwards...

sorry for tripple post, this is my error though

Im having the same issue as above. I can get the demo to record but when finished I have no video or audio file. Any help would be appreciated.

If you go back to that post and read the responses, you'll find that screenshot turned out to be from a successful encoding.

still not seeing a fix. I run the playback I want to, no video file at all shows up after... sorry for my stupidity on coding

JLV I appreciate you trying to help me and the other fellow trying to get this to work. I have tried getting this to work with command prompt as well as just clicking the mxavi file to run it. Neither seem to be working for me. I can get the batch file to run and open the game and view my playback but when im done i receive no video or audio file.
I will try to give as much info as i can to help you help me lol
Here is what my mxavi file looks like if i click edit. Just to make surre it all looks correct to you.

@echo off
path %PATH%;c:\Program Files\MX Simulator

set xres=640
set yres=480

rem For slow motion, raise inputfps (max is 128)
set inputfps=30
set outputfps=30

rem For lossless recording try huffyuv instead of libx264
set vcodec=libx264
set acodec=ac3

mx --record-audio a-stereo-88320.ub --record-video --lock-fps %inputfps% --width %xres% --height %yres% | ffmpeg -y -r %outputfps% -f image2pipe -vcodec ppm -i - -vcodec %vcodec% noaudio.avi

ffmpeg -y -i noaudio.avi -acodec pcm_u8 -ac 2 -ar 88320 -i a-stereo-88320.ub -vcodec copy -acodec %acodec% -ar 44100 -ab 384k video.avi

pause

And here is what i believe to be the errors I keep getting. In command prompt these are the lines that show up highlighted in Yellow and red.
[avi@ 0039EA80] max_analze_duration 5000000 reached at 5000000
