[15:58] <zaki> pavlushka, ffmpeg -find_stream_info -i test.mkv -map 0 -codec copy -codec:s mov_text test.mp4
[15:59] <zaki> a need to do a automation with this. which will find all the mkv in directory and convert to mp4 and remove the original or merge 
[16:00] <zaki> remonshai, any idea? 
[16:01] <pavlushka> zaki: use && find -exec delete kind of
[16:01] <remonshai> sorry.. 
[16:03] <pavlushka> zaki: && find . -name "name" -type f -exec rm -r "{}" \;
[16:03] <pavlushka> zaki: && find . -name "*.mkv" -type f -exec rm -r "{}" \;
[16:05] <remonshai> Why do you need this?
[16:05] <remonshai> I means converting.
[16:06] <zaki> pavlushka, yes
[16:06] <zaki> cause mkv is not supported on many platform 
[16:07] <zaki> I can't play mkv on browser 
[16:07] <zaki> any browser on unix
[16:07] <zaki> IOS 
[16:07] <zaki> sometime it works on windows chrome browser 
[16:08] <zaki> depends on the codec 
[16:08] <zaki> I tried changing mime on the Nginx
[16:08] <pavlushka> i know
[16:08] <remonshai> oh ;/
[16:08] <zaki> so I have two option use a real time transcoder
[16:09] <zaki> or php-ffmpeg module with my php script 
[16:10] <zaki> emby use transcoder and keep the transcoded file in a temporary directory so it works on all device 
[16:10] <zaki> gives output based on client device 
[16:11] <zaki> bt I have another PHP script for movie server, which says it support mkv but it is not 
[16:13] <pavlushka> aha
[16:13] <zaki> so I'm facing issue like if there is 40000 file 60% of its mkv or avi 
[16:14] <zaki>  ffmpeg -find_stream_info -i test.mkv -map 0 -codec copy -codec:s mov_text test.mp4 its works without losing any quality 
[17:51] <zaki> pavlushka, for f in *.mkv; do ffmpeg -i "$f" -c:v libx264 -preset medium -c:a aac -c:s mov_text "${f%.mkv}.mp4"; done
[17:52] <pavlushka> zaki: wow, I don't know bash scripting
[17:55] <zaki> pavlushka, H.264 AAC is the best format and preset medium is for the quality , it takes time to convert with medium preset , you can set it to slower or faster 
[17:55] <zaki> faster will convert the file faster but quality will be worse 
[17:55] <zaki> slower preset will take much time but quality good 
[17:57] <zaki> now I put this script on folders and run sh 
[18:01] <pavlushka> cool
[18:05] <zaki> oh I need to remove the original after 
[18:49] <pavlushka> zaki:  find . -name "*.mkv" -type f -exec rm -r "{}" \;
[18:50] <zaki> && rm *.mkv after the bash script ?
[18:51] <pavlushka> will do
[18:51] <pavlushka> that was for subdirectories included
[18:53] <zaki> will run this per directory 
[18:53] <pavlushka> that appears
[18:56] <zaki> pavlushka, got another 
[18:57] <zaki> rm -f -- "$f" below previous script ,
[18:57] <zaki> it delete file after conversion done. 
[18:58] <zaki> I mean if you have to mkv in the folder it convert 1st one then delete the 1st one source then start the 2nd one 
[19:00] <zaki> ah
[19:00] <zaki> great 
[19:00] <zaki> just tested 
[19:00] <zaki> so my whole script is
[19:01] <zaki> #!/bin/bash
[19:01] <zaki> for f in *.mkv; 
[19:01] <zaki> do ffmpeg -i "$f" -c:v libx264 -preset medium -c:a aac -c:s mov_text "${f%.mkv}.mp4"; 
[19:01] <zaki> rm -f -- "$f"
[19:01] <zaki> done
[19:01] <zaki> pavlushka, ^
[19:02] <zaki> if you have two mkv*
[19:09] <zaki> @pavlushka,  I think I can speed up the process by detecting the codec using ffmpeg before converting and inside mkv container if it found that the codec is already H.264 & AAC it will just copy the codec instead of encoding again and convert to mp4 and if it found other codec inside mkv it will encode to H264 AAC
[19:12] <pavlushka> zaki: wow
[19:12] <zaki> don't know how to search this on google :P 
[19:13] <pavlushka> zaki: you can filter that with mediatype
[19:14] <zaki> where ?
