FFMPEG screen regarding using gdi is working as expected when given offset, width and height on different screen size ?
15 novembre 2018, par Mohsin AbbasI am working on an application that records the screen using ffmpeg. The recording works fine when I don’t specify offset, width and height.
When I specify the offset, width and height on my device and records according to the area but when I run it on a big screen and it records smaller area than provided. I am using following command to record :ffmpeg -f gdigrab -framerate " + Framerate + " -offset_x " + OffsetX + " -offset_y " + OffsetY + " -video_size " + width + "x" + height + " -show_region 0 -i desktop " + FileName;
I think ffmpeg don’t take screen resolution into account or something ?

First overlay text not lasting
14 octobre 2018, par Pier Giorgio MisleyI have this snippet of code, adding two overlayed texts with same effects/durations in two different part of my video.
-i "input.mp4" -filter_complex "color=black:100x100,format=yuva444p[c];[c][0]scale2ref[ct][mv0]; [ct]setsar=1,split=2[t1][t2]; [t1]drawtext=fontfile=Arial.ttf:text='Pippo':fontcolor=white:fontsize=32:box=1: boxcolor=black@0.5:boxborderw=5:x=(w-text_w)/2:y=(h-text_h)/2 - 20,fade=t=in:st=6:d=2:alpha=1,fade=t=out:st=19:d=2:alpha=1[txta1];[t2]drawtext=fontfile=Arial.ttf:text='Topolino':fontcolor=white:fontsize=32:box=1: boxcolor=black@0.5:boxborderw=5:x=(w-text_w)/2:y=(h-text_h)/2 + 20,fade=t=in:st=6:d=2:alpha=1,fade=t=out:st=19:d=2:alpha=1[txta2];[mv0][txta1]overlay=0:0:shortest=1[mv1];[mv1][txta2]overlay=0:0:shortest=1" "output.mp4"
Somewhy, the second text, "
Topolino
" lasts perfectly from the fade-in to the fade-out.The first text ("
Pippo
") is appearing and disappearing immediatly.They have the same effect, so what am I doing wrong ?
Thanks

Revision 4e66293fcb : Use source frame difference to make partition decision Calculate the difference

Use source frame difference to make partition decisionCalculate the difference variance between last source frame and
current source frame. The variance is calculated at 16x16 block
level. The variances are compared to several thresholds to decide
final partition sizes.An adaptive strategy is implemented to decide using
SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions
in the video. The switching test is done once every
search_type_check_frequency frames.The selection of source_var_thresh needs to be investigated
further later.RTC set Borg test showed 0.424% overall psnr gain, and 0.357%
ssim gain. For clips with large enough static area, the
encoding speedup is around 2% to 15%.Change-Id : Id7d268f1d8cbca7fb8026aa4a53b3c77459dc156
