How to add watermark with delay in FFmpeg
28 décembre 2022, par Мохамед РуслановичAm trying to put a gif file in all the edges of the video. So am using this command


ffmpeg -y -i film.mp4 -stream_loop -1 -i gif.gif -filter_complex \ 
"[1]colorchannelmixer=aa=0.8,scale=iw*1:-1[a];[0][a]overlay=
x='if(lt(mod(t\,16)\,8)\,W-w-W*10/200\,W*10/100)':
y='if(lt(mod(t+4\,16)\,8)\,H-h-H*5/200\,H*5/200)':
shortest=1" 
 -acodec copy output_task_3.mp4



But now am required to put the gif file on each edge with delay of 10 minutes


For exmaple :


1- render gif at top left for only 16 seconds.
Then wait 10 minutes


2- render gif at top right for 16 seconds.
Wait 10 minutes


3- rendder gif at right buttom for 16 seconds.
Wait 10 minutes


4- render gif at left buttom for 16 secnods.
Wait 10 minutes


This scenario should be repete till the movie ends.


How can i archive this ?

libavformat/rtpdec : fix issue with conversion from unsigned to signed
20 février 2015, par Gilles Chanteperdrixlibavformat/rtpdec : fix issue with conversion from unsigned to signed
When receiving an RTCP packet, the difference between the last RTCP
timestamp and the base timestamp may be negative. As these timestamps
are of the uint32_t type, the result becomes a large integer. Cast
the difference to int32_t to avoid this issue.The result of this issue is very large start times for RTSP
streams, and difficulty to restart correctly after a pause.Signed-off-by : Gilles Chanteperdrix <gilles.chanteperdrix@xenomai.org>

init seg_duration option for dash similar to -hls_init_time option
5 août 2019, par SaurabhIs there any option to set first segment duration for dash files, There is similar option for HLS : hls_init_time ?
I could not found any such option in documentation.
Why I want such option to be there :
From generated DASH files : in Android ExoPlayer, It always plays first chunk of lowest quality(bitrate/resolution), after first chunk, basis user’s internet speed, it picks the next chunk. If there is no init_seg_duration option, I have to rely only on seg_duration and I can not keep it bit large. Why I will like to keep it large : to reduce the number of files generated.
With such option, I could had given
-init_seg_duraion 2 -seg_duration 6
, so video quality would had increased after 2 seconds and total number of files generated would also not had exploded.
