Re: [FFmpeg-user] Which videoc codec gives best compression for screen recording?

2014-11-13 Thread Kuban Altan
I would also give a shot for *quicktime animation* codec *(-vcodec qtrle)*. Which can be lossless. But you have to test for file sizes. Which one gives you better file size and minimum cpu load? kuban altan On Thu, Nov 13, 2014 at 2:18 PM, Carl Eugen Hoyos wrote: > Tobias Rapp noa-audio.

Hi I suppose that, x264 has a lossless mode when the quantizer scale is set to 0. If that is also applicable to libx264rgb, then it is worth to look at. So your pixels will still stay rgb, and you will have x264 efficiency in lossless mode. kuban altan On Thu, Nov 13, 2014 at 1:52 PM, Tobias

[FFmpeg-user] processing a vumeter (levelmeter) as video for audio inputs

2014-11-07 Thread Kuban Altan
(for 25fps)... So I can get a peak sound level as text output using volumedetect. But this is not very efficient. All I need is a video and 2 rectangular bars, which have their lengths connected to input audio level. Any ideas on doing this? kuban altan

Re: [FFmpeg-user] Generating an rgb24 pix_fmt solid color using lavfi by default

All I want to do is, generate a solid color in rgb24 pixel format. Is there any other way to achieve this? (Other than using an input rgb24 file? I don't want to make this command line dependant on an external image file) kuban altan On Thu, Oct 30, 2014 at 1:15 AM, Carl Eugen Hoyos
