I have a .m3u8
file on remote host, with contain fixed numbers of chunk .ts
file name, and not stream:
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:11
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:9.736,
media_0.ts
#EXTINF:9.96,
media_1.ts
#EXTINF:10.0,
media_2.ts
#EXTINF:10.0,
media_3.ts
#EXTINF:10.0,
media_4.ts
#EXTINF:10.2,
media_5.ts
#EXTINF:10.0,
When I use this command:
# ffmpeg -i "http://example.com/chunklist.m3u8" file.mp4
frame= 582 fps=9.4 q=28.0 size= 1536kB time=00:00:23.21 bitrate= 542.1kbits/s dup=2 drop=4 speed=0.375x
It works. But It get frame by frame video and very long time needed. (It takes time almost to playback the video.)
But since the path of all the .ts
files are known. (http://example.com/media_0.ts, http://example.com/media_1.ts, ...) There must be a way to get and merge them all at the same time.
But How in ffmpeg
directly?!
For one solution, I know how can concatenation files with ffmpeg.
ffmpeg -i "concat:0.ts|1.ts|2.ts|3.ts|4.ts|5.ts" -c copy output.mp4
This ffmpeg command was great, and works in less 1 sec time!
So try to download all .ts
files with CURL with this command:
curl \
http://example.com/media_0.ts -o 0.ts \
http://example.com/media_1.ts -o 1.ts \
http://example.com/media_2.ts -o 2.ts \
http://example.com/media_3.ts -o 3.ts \
http://example.com/media_4.ts -o 4.ts \
http://example.com/media_5.ts -o 5.ts
But you can see result:

See, total download time was 72 sec, while the total duration of all parts is 59 sec! that this time is very long!
So sorry, download all parts and then concat that, was not good solution.
I try for another .m3u8
file on the another server with difference URL:
Download and concat together:
ffmpeg -i "concat:\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_0.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_1.ts|\
http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_2.ts|\

http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_5.ts\
" -c copy -y output.ts
Another command with input.txt
URLs file.
ffmpeg -f "concat" -i "input.txt" -c copy -y output.ts
input.txt file:
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_0.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_1.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_2.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_3.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_4.ts'
file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_5.ts'
Or this command some time if needed:
ffmpeg -f "concat" -safe "0" -protocol_whitelist "file,http,https,tcp,tls" -i "input.txt" -c copy -y output.ts
Finally, for that download speed was good, MAYBE my server target has limited bandwidth. :-(
The correct way to concat multiple video files from m3u8 playlist is
ffmpeg -i "http://example.com/chunklist.m3u8" -codec copy file.mp4
-codec copy
to avoid encoding (which takes time)*.mp4
is fine but it seems little slow to mux when playlist is fetched from web*.mkv
or *.ts
worked best for me
