Resize and overlay image on video in android efficiently
29 décembre 2016, par Bhushan LadheI want to resize image and video(2160 x 3840) to a same resolution(540 × 960) and then overlay image on video for whole time. This whole process is similar to capturing video and adding caption to it like snap-chat and saving it.
Since i am successful in doing so using FFMPEG library but it consumes considerable amount of time in processing.
I have searched the internet for other faster operations but no luck. I will post commands that i am using.
//1st command (video size from 59MB to 4MB, about time 110secs)
-i sdcard/VID_20161228_174315.mp4 -vf scale=540:960 sdcard/output540.mp4
//2nd command (image file , size done, time : a sec hence ignored)
-i sdcard/capture.jpg -vf scale=540:960 sdcard/capture540.png
//3rd command (time 80sec)
-i sdcard/output540.mp4 -i sdcard/capture540.png -filter_complex overlay=0:0 -r 30 sdcard/output_overlay.mp4So here using -preset and copying same audio from source did not work as expected.
Questions :
1) Should i use specific codec ?
2) How to achieve Minimum time for processing ?
3) Will applying multiple threads help ? If yes then how ? I want this process to work in background even if app is closed.
4) All other options that can combine to make an efficient solution ?
Log for 3rd command :

Android : Select from images extracted with FFMPEG

Intel QuickSync error : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
30 novembre 2018, par Arie SyamsudinI want to make IPTV with a topology like this :
Restream / source -----> IPTV server -----> User
The problem at the moment is the question of bandwidth that is still large.
Finally I announced by IPTV software providers to transcode with Intel QuickSync video and FFmpeg.
I followed the steps given by the software provider at the following link :
http://www.ezhometech.com/document/intel_ffmpeg.txtWhich comes from the link below :
https://www.intel.com/content/dam/www/public/us/en/documents/white-paper...I installed IPTV software on a laptop with an Intel processor, chipset and VGA.
