As to the second part of your question (not in the header) Use xdpyinfo instead, if you want to read something like screen resolution. It doesn't cause that brief freeze.

Converting image based subtitles to text is a nontrivial process, as you will need some kind of OCR system to interpret the bitmaps and figure out what the corresponding text is. ffmpeg alone will not do that for you. I am not aware of any app that will do the whole process in one go, for Linux/UNIX. However, this process should work: Extract the ...

If you want to crop and scale in one go, you can make a crop-then-scale filterchain like so: ffmpeg -i SomeInput.mp4 -vf "crop=in_h*9/16:in_h,scale=-2:400" -t 4 SomeOutput.mp4 The above first crops a video to 16:9 portrait, then scales to 400px high x the appropriate (even number) width.

You cannot loop .mp4 files, but as a workaround you can use e.g. -loop 5 to multiply the animation in the resulting .mp4 file 5 times. This will result in 5 times bigger file, but you will not have any jitter between these 5 animations.

You can make a looping GIF by setting a bit in the header of the file (been doing that since 1989), but there is no such facility that I know of in the .mp4 files. For them looping is controlled via an additional, player dependent, file. The absence of that also is the reason why you don't have any looping .mp4 on YouTube.

ffmpeg is an OS agnostic tool that is capable of determining if a video file has been completely downloaded. The command below instructs ffmpeg to read the input video and encode the video to nothing. During the encoding process, any errors such as missing frames are output to test.log. ffmpeg -v error-i FILENAME.mp4 -f null - 2>test.log If a video ...
