I'm confused because this is happening with every DVRMS file (received from multiple users). how can every file be corrupted? I did not want to imply that FFmpeg is dropping frames because the input file is corrupted. (Did I really write this?) With the WTV you isolated the issue to wrong FPS which was corrected manually and it fixed the problem. With DVRMS files, i'm trying to figure out if FFMPEG is able to process the files correctly or not? If every DVRMS file is dropping frames then possibly something is wrong with FFMPEG. Is my assumption correct? I don't think so, and please note that setting the frame rate for Test1.wtv did not fix the problem you had namely initially dropping or duplicating frames. -- Ticket URL: https://ffmpeg.org/trac/ffmpeg/ticket/1297#comment:30 FFmpeg http://ffmpeg.org FFmpeg issue tracker ___ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac

Comment (by cehoyos):
Replying to [comment:19 ramitbhalla]:
1. Yes tried with a lower resolution (1024x768 - the lowest possible)
and output video is still stuttering.
What do you mean with lowest possible?
I tried 320x180 and I find the video still very watchable at least for
testing and I do not see any stuttering, it also works fine with 640x360.
I do see stuttering with higher resolutions because my current setup
cannot play 60fps movies with (for example) 960x540 or higher resolutions.

Is it something that I'm doing wrong in the command line (as in the WTV case, actually that was an issue of FFMPEG getting a wrong frame rate for which I'll report the issue in a separate ticket/update the existing ticket) or is there an underlying issue with FFMPEG. 1st step is to curb the drop/dup packet, 2nd step would be to figure out what's really the source of the stutter - correct me if I'm wrong here. -- Ticket URL: https://ffmpeg.org/trac/ffmpeg/ticket/1297#comment:25 FFmpeg http://ffmpeg.org FFmpeg issue tracker ___ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac

Comment (by ramitbhalla):
Setting the frame rate doesn't appear to solve the problem. I'm attaching
a dvr-ms file (this is one cut sample, others are also facing similar
issues).
As you can see from the output it keeps dropping the frames. I've tried
different settings with -r 24, -r 25, -r 30, -r 50, -r 60, -r
30*1000/1001, -r 60*1000/1001, -r 25*1000/1001 and none of them seem to
work, it still leads to the same issues of dropping frames and the video
stutters when played back.
Any idea why this is happening?

1. Yes tried with a lower resolution (1024x768 - the lowest possible) and
output video is still stuttering.
2. I gave the basic commmand line and issue, here is the one with the rate
adjustment and the output. This is happening with all the DVR-MS files I
have.

Comment (by ramitbhalla):
Thanks for looking into this.
1. How do you know what frame rate to choose? Why 25 and not 30 or
1001/1000 etc?
2. I'm still getting the duplicated frames error (see below)
Here is the command:
{{{
ffmpeg -i test1.wtv -vcodec mpeg2video -sameq -r 25 -an test.ts
}}}
Here is the output:

This needs -r 25.

I would expect there is a performance problem when playing the resulting
file, at least that is what I see here on old hardware, it disappears if I
reduce the resolution or play with half speed.
In the future, please do not report two unrelated problems in one bug
report, it makes tracking bugs impossible.

I'm trying to transcode different video types to TS MPEG2 video and FFMPEG
creates stuttering video with some files (some are okay say about 20% are
stuttering).
Since the files are too big to attach (each 60MB) I've uploaded them and
including the links to the 2 files below:
