When I convert video through avconv it's take above 95% percentage, is there any way to reduce the converting time?
Try using -threads auto or push it to the number of cores / threads your CPU has.
Here is my full script
#!/bin/sh
infile=$1
tmpfile="$1-tmp.mp4"
outfile="$1-new.mp4"

To merge files with ffmpeg I'm creating a text file like this:
file 'a.mkv'
file 'b.mkv'
file 'c.mkv'
Then I'm running this command to concat these videos:
ffmpeg -f concat -i file.txt -c copy merged.mkv
But the thing is, I want to put red frame for three seconds in the middle of each video.
Now I can get these videos' frame dimensions and create a video and modify the text file like this:
file 'red.mkv'
file 'a.mkv'
file 'red.mkv'
file 'b.mkv'
file 'red.mkv'
file 'c.mkv'
But this is not a programmatical approach, so is there any way I can concat videos and put red frames for three seconds (before every video)?
I want to generate that red frame video, on run time.
bash script:
#!/bin/bash
intro=a.mkv
main=b.mkv
outro=c.mkv
red=red.mkv
VID=$(ffprobe -v 0 -select_streams v:0 -show_entries stream=codec_name -of default=nw=1:nk=1 "$main")

SAR=$(ffprobe -v 0 -select_streams v:0 -show_entries stream=sample_aspect_ratio -of default=nw=1:nk=1 "$main")
if [ "$SAR" = "N/A" ]; then SAR=1; fi
FPS=$(ffprobe -v 0 -select_streams v:0 -show_entries stream=r_frame_rate -of default=nw=1:nk=1 "$main")
# if video has variable framerate, you can get something like 22840/769
FPS=30
TBN=$(ffprobe -v 0 -select_streams v:0 -show_entries stream=time_base -of default=nw=1:nk=1 "$main")
TBN=${TBN#*/}

echo $VID $WID $HEI $SAR $FPS $TBN $FMT
AUD=$(ffprobe -v 0 -select_streams a:0 -show_entries stream=codec_name -of default=nw=1:nk=1 "$main")

SRA=$(ffprobe -v 0 -select_streams a:0 -show_entries stream=sample_rate -of default=nw=1:nk=1 "$main")
echo $AUD $CHL $SRA

echo "file '$intro'" > $l
for f in $main $outro; do
[[ ! -f $f ]] && continue
echo "file '$red'" >> $l
echo "file '$f'" >> $l
done
cat $l
ffmpeg -f concat -i list.txt -c copy output.mp4 -y
mpv output.mp4
maybe, you have to add something to this code
I have 10 images(1080x1920) and 2 video(1080x1920).
I want to merge all of them to make a final video using command:

I run this command on a virtual machine (Linux, 4GB memories) and it takes ~11 min to finish! It takes too long and I want to reduce the process time to less than 5 min.
Any suggestion for the better performance.
I'm using ffmpeg to create slideshow of images.
I have to add music in the backgroup which will be played to the size of the slideshow (slicing audio if audio length is greater than video or repeating audio if audio length is shorter than video)
This is what my script is
ffmpeg -y \
-loop 1 -i in1.png \
-loop 1 -i in2.png \
-loop 1 -i in3.png \
-loop 1 -i in4.png \
-loop 1 -i in5.png \

This generates output, but slideshow is silent and there is no music in the video.
You need to also map the audio:

I made a simple script that divides a flv file into multiple parts, converts them all to .mp4 individually and then merge all of them to form a final mp4 file. I did this to save time and convert large files in parallel.
However, I am stuck because the command that normally runs on command line for ffmpeg, doesn't run via script.
I am kind of stuck here and will like to have some assistance.
#!/bin/bash
#sleep 5
filenametmp=$1;
filename=`echo "$filenametmp" | awk '{split($0,a,"."); print a[1]}'`
echo $filename

echo $output $filenamewithoutpath

I run any flv file like this :

I am on Ubuntu 14.04 LTS version, standard installation of ffmpeg.
I have a mp4 file or other file (non mp4 format) and i need generate ts files and m3u8 playlist.
I am using this command and works fine:
ffmpeg -i foo.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment
-segment_list out.m3u8 -segment_time 10 out%03d.ts
Now I need to generate many ts simultaneous so i need a "resume option".
Please see the example below:
One thread (first 20 seconds (0-20))
ffmpeg -i foo.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment
-segment_list out.m3u8 -segment_time 10 out%03d.ts
Seconds thread (20 seconds to 40 seconds)
ffmpeg -i foo.mp4 ......
Third thread (40 seconds to 60 seconds)
ffmpeg -i foo.mp4 ......
I have lots of core processor to do this jobs.
In resume i need generate .ts files and m3u8 fastest way possible
I need help or advises to resolve my problem.
Prove of concept i build a litle script that use -ss and -t option:
<?php
//generate all the commands using -ss and -t <seconds>
$startTime = new DateTime("00:00:00");
for ($i=1; $i < 20; $i++) {
$data = $startTime->format('H:i:s');
$exec = 'ffmpeg -i "<FILE>" -ss '.$data.' -t 10 -c:v copy -bsf h264_mp4toannexb -flags -global_header -map 0 -f segment -segment_time 10 -segment_start_number '.$i.' -segment_list '.sprintf("%04d", $i).'_test.m3u8 -segment_format mpegts '.$i.'stream%05d.ts';
shell_exec($exec);
$startTime->modify('+10 seconds');
echo "\n";
}
//cycle all m3u8 and creates a master hls playlist
$files = glob('*.{m3u8}', GLOB_BRACE);
sort($files);
$ret = "#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOW-CACHE:YES
#EXT-X-TARGETDURATION:11
";
foreach($files as $file) {
$ret .= shell_exec('sed -n -e 6,7p '. $file);
}
$ret .= "#EXT-X-ENDLIST";
file_put_contents('final.m3u8', $ret);
?>
Thanks
