Re: Windows XP compatible non-SSE2 FFmpeg builds

Isn't native ffmpeg encoder called "mpeg4" (-c:v mpeg4) able to do the same thing as libXviD? Yes, pretty much, but for some encodes I do see a difference in quality. https://github.com/rdp/ffmpeg-windows-build-helpers/issues/219#issuecomment-292819242 : I've just done 2 quick XviD encodes on a 640...

Re: Windows XP compatible non-SSE2 FFmpeg builds

Your welcome! Your posts are not boring at all. It's good to hear everything works.
It's sounds like you don't miss any of the libraries I've removed, so that's also good to hear.

Re: Windows XP compatible non-SSE2 FFmpeg builds

Fresh builds. See post #1.

A big clean-up of hardly used libraries!
At first I didn't want to remove libvmaf, but it requires another compiler now called Meson. Meson in turn requires Python 3.5.0 or newer, which isn't compatible with Windows XP.

Re: Windows XP compatible non-SSE2 FFmpeg builds

Could someone advise me, as I want to run ffmpeg.exe on Win XP SP3 on Intel Core 2 Duo (T5500 and E2180) what version should I download? Is it correct that I should be using build with SSE2 support?? Hmm, I wasn't notified by your post. Strange. Anyway, as manolito already mentioned, Zeranoe's buil...

Re: Help with converting to AVI file using FFMpeg

./ffmpeg.exe -i <input-filename> -f avi -c:v rawvideo -pix_fmt bgr24 output.avi -f avi and -pix_fmt bgr24 aren't needed. If you only want to compare the videotrack, then you can add -an to exclude the audiotrack (from being converted to mp3): ffmpeg -i "AVI(Uncompressed)-SD.avi" -c:v rawvideo -an o...

Re: Video bit depth

I'm a bit confused by the zscale filter suggestion. It does resolution- , range- and colormatrix-conversions, but it doesn't change the pixel-format as far as I know. Aorangi, I have no idea what "Davinci resolve" is, but if you want to convert your video to 4:2:0 8-bit, then... ffmpeg -i <input> -p...

ffmpeg -i input.avi -acodec mp3 out.avi
'out.avi' should in this case be created in the same map as 'input.avi'.
I suggest you search the internet on how to use command-line programs.

Re: multiply audio pcm to 5.1

Can you please be more accurate in describing your current situation and what you want?!
It is unclear to me whether you either have 1 wav-file with 16 channels that you want save as 16 separate ones, or 16 separate wav-files that you want to merge to 1 wav-file.

Re: Speed Up Video

I need to get 60 fps and the input video is 50 fps. So, 50/60 is 0.8333. Well, that's very confusing, because in your first post you said: "I want to speed up a video sequence from 30 fps to 60 fps " . Please make up your mind. In that case 11.13s * 5 / 6 = 9.275s is exactly what you get with setpt...

Re: Speed Up Video

The outfile.avi number of frames is 555 and the duration is 9.25 sec. I'm not sure why this is happening. It's the result of setpts=0.833*PTS. I don't understand how you came up with 0.833. ffmpeg -i input.avi -lavfi setpts=0.5*PTS -r 60 -c:v rawvideo output.avi This should do the trick. Also see H...
