[Solved] Problem with video and audio stuttering
Hello everyone ![Smile :)](./images/smilies/icon_e_smile.gif)
From time to time some video files playback stutters for me. After some time playback 90% of time goes back to normal, sometimes it doesn't.
I have noticed today in debug this info:
DEBUG 2018-02-20 18:56:55.902 [mencoder.exe-4-2] [mpeg2video @ 01fd8940]rc buffer underflow
DEBUG 2018-02-20 18:56:55.903 [mencoder.exe-4-2] [mpeg2video @ 01fd8940]max bitrate possibly too small or try trellis with large lmax or increase qmax
How can I fix this problem?
Thank you very much in advance!![Smile :)](./images/smilies/icon_e_smile.gif)

Re: Problem with video and audio stuttering
Have you tried to use FFmpeg (which is the default transcoding engine) instead of Mencoder?
Re: Problem with video and audio stuttering
Yes, I've tried to use mencoder becouse sometimes problem didn't happen then.
With ffmpeg:

And this message seems to happen when problem pops-in.

Re: Problem with video and audio stuttering
Is your CPU powerful enough? What CPU do you have?
Re: Problem with video and audio stuttering
I5-3570k, 8GB RAM, Windows 10. Although problems like these I had even when I had Win8.1.
Re: Problem with video and audio stuttering
Hmm, that should be plenty. I was just an idea, but it seems like a dead end.
Re: Problem with video and audio stuttering
I thought that maybe my HDD is a problem, but I have tried and moved files to SSD but it didn't help.
Re: Problem with video and audio stuttering
The discussion is worthless when you not follow the instruction written in red above and not send the log.
Re: Problem with video and audio stuttering
Of course, I am sorry.
Here is the log file. I run the file for 2+ minutes and problems appears @9s and @2min10s

Re: Problem with video and audio stuttering
Zippyshare is full of intrusive ads and generally inconvenient for us, so I'm attaching the file here.
