If you use other language than english you get problem with printf in the bash script
../hls.sh ../output-video.mp4 l2r 0 0
../hls.sh: Zeile 36: printf: 5.00000000000000000000: Ungültige Zahl.

so try this and you get rid of it.

Hi There,
I have a question - hope you can support me.
Many thanks
is it possible to add "ffprobe source.mp4" and detect input height,
then create HLS resolution =< source ?
example :
source.mp4 is 720p ( 1280x720 )
then create HLS 720p, 480p, 360p, 240p
another thing is:
for example if source is between 1080p and 720p then again output will begin from 720p and so on
if source is between 2160p and 1080p then again output will begin from 1080p and so on
looking for same, did you find a way ?

Option hwaccel (use HW accelerated decoding) cannot be applied to output url cuda -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.
Error parsing options for output file cuda.
I get this error. Could you please help me?
This is my extended version of this script that supports auto generate bitrates based on video source resolution, and handle cases when video after scaling has dimensions are not divisible by 2 that will cause error at run time.

It seems this script only outputs the filename on the next line after each #EXT-X-STREAM-INF line and this seems to 'break' any m3u8 playlist file because the entire URL to the file has to exist, no? (reference from Apple https://developer.apple.com/documentation/http_live_streaming/example_playlists_for_http_live_streaming/creating_a_master_playlist)
On other words, I cannot get this to work with this example:
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360
360p.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=2800000,RESOLUTION=1280x720
720p.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1920x1080
1080p.m3u8
It seems to only work if I cite the URLs to the files:
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-STREAM-INF:BANDWIDTH=800000,RESOLUTION=640x360
http://mydomain.com/360p.m3u8

You are a life saver ! Works great !
Tho thanks to OP for first answer !
Tho i wonder for exampe how dose sfari determines which resultion to take from the playlist?
By screen size? by network speed? latency etc... ?
P.S
How can i force it to split to even more chunks ? it dose like 3 chunks for 22 seconds video
Can i force it into more ?
Hi, thanks for you script. I need help with other problem. I have one video with multiple quality and multiple audios. The audio have the same quality. How i can modify script for this.
Example
video1 --> 1080 | 720 | 480
audio --> english | spanish (same quality)
It possible?
Thanks!

hi, is there any way to include codec info as well in manifest?
Currently it is like:
#EXT-X-STREAM-INF:BANDWIDTH=5000000,RESOLUTION=1920x1080```
What i want is :
#EXT-X-STREAM-INF:BANDWIDTH=767744,AVERAGE-BANDWIDTH=720351,CODECS="avc1.4d401f,mp4a.40.5",RESOLUTION=640x480,FRAME-RATE=29.970
Is there a way to get CODECS in the manifest? If I use the following command:
ffmpeg -y -i ~/work/sample-videos/flowers.mp4 \
-preset slow -g 48 -sc_threshold 0 \
-map 0:0 -map 0:1 -map 0:0 -map 0:1 \
-s:v:0 640x360 -c:v:0 libx264 -b:v:0 365k \
-s:v:1 960x540 -c:v:1 libx264 -b:v:1 2000k \
-c:a copy \
-var_stream_map "v:0,a:0 v:1,a:1" \
-master_pl_name master.m3u8 \
-f hls -hls_time 6 -hls_list_size 0 \
-hls_segment_filename "v%v/fileSequence%d.ts" \
v%v/prog_index.m3u8
CODECS are auto included for h264(for above command) but the above command does not support resolution based naming of segments.
Thanks
I tried to get all the segments for 10 seconds except for the first one which will be of 5 seconds by passing-hls_init_time 5 -hls_time 10 -hls_playlist_type VOD but seems like hls_time is being ignored all together, i.e. all the segments are of 5 seconds instead of 10. Am I doing something wrong? Can someone help?
Hi @mrbar42. Thank you for great script! Why resolution is 842x480 but by standard it is 854x480? from here https://support.google.com/youtube/answer/6375112?co=GENIE.Platform%3DDesktop&hl=en

There are many iterations of 480p; use the one relevant to your most prevalent client device.

I change L:35 to awk
key_frames_interval="$(awk "BEGIN { rounded = sprintf(\"%.0f\", ${key_frames_interval}); print rounded }")"

How about having differntial segments accoding to the duration of the original video. For example, having shorter segments for the first 10% duration of video and then longer segments for the rest 90%?
I was looking for a code to convert video files in a directory where it has multiple subfolders for each video file. I want to run a batch code so it can convert the video files and save them where the original file was there.
Example:
: tree movies/
movies/
├── subfolder1
│ └── movie1.mp4
├── subfolder2
│ └── movie2.mp4
└── subfolder3
└── movie3.mp4
And so on.
I want the output to be the same as my main structure but in .m3u8 format.
I have used a code where it can convert each movie manually but for some reason, I can use the .m3u8 file or link only in that server I can't make it work all over the internet.
for i in .mp4; do
ffmpeg -i "$i" -c copy -map 0 -hls_time 3 -hls_list_size 0 -f hls "${i%.}.hls"
done
Thanks
@DravitLochan i am also thinking like you to initial hls video size size is small like first few are divided in 2 sec chunk and then after 10 sec we make it to 5 sec chunk.
so have you achieved this solution ?
so something we can do 5 chunk are in increasing order like 1s,2s,3s,4s,5s and then all remain are 5s/10sec chunk
Isn't it easier to create a master playlist file using FFMPEG itself?
Using -master_pl_name param
Great script to get started, doesn't play in Safari though, might be the codec this script is using.
It works fine on my server CentOS 7. I have 16 Core 16GB RAM but it has all the RAM and CPU. And the one problem I encountered is that I have a 1080p mp4 video file of about 700MB. After the encoder has finished, the total size of 1080p files is up to 1.2GB.
Another problem is that it has too many files in a 40 minute video. It up to thousands of files, they are fragmented and reduce the read speed of the hard drive!
