Problems transcoding avi to mp4

Post by wvdvegt » Wed Dec 09, 2015 8:33 am

Hi

Since the last 5-6 releases (so quite some time) I get floating point errors (and others) in the encoding logfile during the video pass. To stop the failing transcoding process i have to kill MediaCoder in the taskmanager.

Mkv to mp4 works ok every time.

The problems with avi's make MediaCoder a lot less usable and I have to resort to other utilities to get the job done.

Some of the output in the console window:

Hi

I would not mind some response as the issue is still present in the latest update and still renders MediaCoder utterly useless for me!

This is what I try to encode. Even the playback video is distorted (but the windows media player plays it correctly).

I saw some logging entries regarding vfm=xvid codec

Requested video codec family [xvid] (vfm=xvid) not available.

Even though I have xvid installed!

and found this link ( MPlayer ):

As we seemingly have to solve our issues by our own :x ,

I managed to get rid of the float errors by replacing MPlayer as demuxer by Mencoder.

No idea yet if it results in a output file as encoding is still running.
