Hi I am trying to capture desktop with ffmpeg gdigrab. I am using SSH connection to remotely use admin cmd on windows 10 pc. When i execute this command normally it works but remotely it doesnt.
ffmpeg -f gdigrab -framerate 30 -i desktop output.mkv

I'm trying to scale my input video to standard 1280x720 resolution, but my output looks blurred when compared to the input.

I have a simple gif. I am not in general familiar with FFmpeg commands so I assume it's just my syntax being wrong, but what I'm using is straight from an answer here so I thought it would work.
I'm trying to add a delay on the last frame of my gif.
ffmpeg -i out.gif -vf tpad=stop_mode=clone:stop_duration=2 out2.gif
But I'm getting this when I try it:

I have the raw video data from a video stream (no audio) and the duration when I play the raw video in VLC is ~67 seconds. When I convert the file to MP4 using FFMPEG the duration is 82.68 seconds.
Video is available here: https://www.filedropper.com/showdownload.php/67seconds
I am using FFMPEG/FFPROBE version git-2020-07-21-b5f1e05 on Windows.
Details of the raw video here:

The mp4 duration matches my ffprobe calculation against the raw file itself (2067/25 = 82.68 seconds):
ffprobe -show_entries stream=r_frame_rate,nb_read_frames -select_streams v -count_frames -of compact=p=0:nk=1 -v 0 67seconds.raw
25/1|2067
What would explain this difference in durations between the raw playback and the FFMPEG interpretation and how do I encode to the same duration for this and other stream data?
I have a VOB file holding an MPEG-2 video track with an AC-3 audio track. The video track of that VOB file consists of a single frame, which when played in a DVD player, holds that still frame until the audio track has finished.
How can I (with FFMPEG ideally), loop that frame to make a "normal" video track that lasts for the length of the audio track, rather than just a single frame?
