FFMPEG Re-encode video after concatenation with complex filters












1














I have a bash script for FFMPEG which accepts two inputs Awoo.mkv and Awoo1.mkv.



./ffmpeg -y 

    -i Awoo.mkv 

    -i Awoo2.mkv


These two files are concatenated using a complex filter, this is because in the future files with different codecs will be concatenated as well. Two outputs from this filter are created [outv] and [outa].



-filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 

-map '[outv]' -map '[outa]'


The video is then re-encoded with various settings into two separate streams. Stream v:0 and a:0 is in 1080, stream v:1 and a:1 is in 720.



-c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k 

-c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k


The final output is in HLS so some details for that are included



-hls_time 6 

-hls_list_size 2 

-hls_flags delete_segments 

-f hls -master_pl_name "${name}.m3u8"


The re-encoded output streams are then mapped, at this point there are two outputs for the different quality settings.



-map 0:v -map 0:a -map 0:v -map 0:a


A variant stream mapping is then defined to include both output streams into the m3u8 playlist.



-var_stream_map "v:0,a:0 v:1,a:1"


And finally some extra details for HLS.



-hls_segment_filename "sequence/${name}_%v-%d.ts" 

"sequence/${name}_%v.m3u8"


The is the entire script.

./ffmpeg -y 

    -i Awoo.mkv 

    -i Awoo2.mkv 

    -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 

    -map '[outv]' -map '[outa]' 

    -c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k  

    -c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k  

    -hls_time 6 

    -hls_list_size 2 

    -hls_flags delete_segments 

    -f hls -master_pl_name "${name}.m3u8" 

    -map 0:v -map 0:a -map 0:v -map 0:a 

    -var_stream_map "v:0,a:0 v:1,a:1" 

    -hls_segment_filename "sequence/${name}_%v-%d.ts" 

    "sequence/${name}_%v.m3u8"


I know that without the concatenation filter and a single input this script works fine, i'm having trouble working out how exactly I can work the concatenation filter into it, especially with the mapping command and how it works.



If I try to run this script in it's current state I get the error:



[hls @ 0x6a30180] Unable to find mapping variant stream

    I have a bash script for FFMPEG which accepts two inputs Awoo.mkv and Awoo1.mkv.



    ./ffmpeg -y 
    
    -i Awoo.mkv 
    
    -i Awoo2.mkv


    These two files are concatenated using a complex filter, this is because in the future files with different codecs will be concatenated as well. Two outputs from this filter are created [outv] and [outa].



    -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 
    
-map '[outv]' -map '[outa]'


    The video is then re-encoded with various settings into two separate streams. Stream v:0 and a:0 is in 1080, stream v:1 and a:1 is in 720.

      I have a bash script for FFMPEG which accepts two inputs Awoo.mkv and Awoo1.mkv.



      ./ffmpeg -y 
      
    -i Awoo.mkv 
      
    -i Awoo2.mkv


      These two files are concatenated using a complex filter, this is because in the future files with different codecs will be concatenated as well. Two outputs from this filter are created [outv] and [outa].



      -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 
      
-map '[outv]' -map '[outa]'


      The video is then re-encoded with various settings into two separate streams. Stream v:0 and a:0 is in 1080, stream v:1 and a:1 is in 720.



      -c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k 
      
-c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k


      The final output is in HLS so some details for that are included



      -hls_time 6 
      
-hls_list_size 2 
      
-hls_flags delete_segments 
      
-f hls -master_pl_name "${name}.m3u8"


      The re-encoded output streams are then mapped, at this point there are two outputs for the different quality settings.



      -map 0:v -map 0:a -map 0:v -map 0:a


      A variant stream mapping is then defined to include both output streams into the m3u8 playlist.



      -var_stream_map "v:0,a:0 v:1,a:1"


      And finally some extra details for HLS.



      -hls_segment_filename "sequence/${name}_%v-%d.ts" 
      
"sequence/${name}_%v.m3u8"


      The is the entire script.



      name=gw
      

      
./ffmpeg -y 
      
    -i Awoo.mkv 
      
    -i Awoo2.mkv 
      
    -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 
      
    -map '[outv]' -map '[outa]' 
      
    -c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k  
      
    -c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k  
      
    -hls_time 6 
      
    -hls_list_size 2 
      
    -hls_flags delete_segments 
      
    -f hls -master_pl_name "${name}.m3u8" 
      
    -map 0:v -map 0:a -map 0:v -map 0:a 
      
    -var_stream_map "v:0,a:0 v:1,a:1" 
      
    -hls_segment_filename "sequence/${name}_%v-%d.ts" 
      
    "sequence/${name}_%v.m3u8"


      I know that without the concatenation filter and a single input this script works fine, i'm having trouble working out how exactly I can work the concatenation filter into it, especially with the mapping command and how it works.



      If I try to run this script in it's current state I get the error:



      [hls @ 0x6a30180] Unable to find mapping variant stream

      I have a bash script for FFMPEG which accepts two inputs Awoo.mkv and Awoo1.mkv.



      ./ffmpeg -y 
      
    -i Awoo.mkv 
      
    -i Awoo2.mkv


      These two files are concatenated using a complex filter, this is because in the future files with different codecs will be concatenated as well. Two outputs from this filter are created [outv] and [outa].



      -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 
      
-map '[outv]' -map '[outa]'


      The video is then re-encoded with various settings into two separate streams. Stream v:0 and a:0 is in 1080, stream v:1 and a:1 is in 720.



      -c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k 
      
-c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k


      The final output is in HLS so some details for that are included



      -hls_time 6 
      
-hls_list_size 2 
      
-hls_flags delete_segments 
      
-f hls -master_pl_name "${name}.m3u8"


      The re-encoded output streams are then mapped, at this point there are two outputs for the different quality settings.



      -map 0:v -map 0:a -map 0:v -map 0:a


      A variant stream mapping is then defined to include both output streams into the m3u8 playlist.



      -var_stream_map "v:0,a:0 v:1,a:1"


      And finally some extra details for HLS.



      -hls_segment_filename "sequence/${name}_%v-%d.ts" 
      
"sequence/${name}_%v.m3u8"


      The is the entire script.



      name=gw
      

      
./ffmpeg -y 
      
    -i Awoo.mkv 
      
    -i Awoo2.mkv 
      
    -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" 
      
    -map '[outv]' -map '[outa]' 
      
    -c:v:0 libx264 -b:v:0 4000k -s:v:0 1920x1080 -r:v:0 30 -g:v:0 90 -preset:v:0 superfast -tune:v:0 zerolatency -level:v:0 4 -pix_fmt:v:0 yuv420p -c:a:0 aac -b:a:0 512k  
      
    -c:v:1 libx264 -b:v:1 2500k -s:v:1 1280x720  -r:v:1 30 -g:v:1 90 -preset:v:1 superfast -tune:v:1 zerolatency -level:v:1 4 -pix_fmt:v:1 yuv420p -c:a:1 aac -b:a:1 256k  
      
    -hls_time 6 
      
    -hls_list_size 2 
      
    -hls_flags delete_segments 
      
    -f hls -master_pl_name "${name}.m3u8" 
      
    -map 0:v -map 0:a -map 0:v -map 0:a 
      
    -var_stream_map "v:0,a:0 v:1,a:1" 
      
    -hls_segment_filename "sequence/${name}_%v-%d.ts" 
      
    "sequence/${name}_%v.m3u8"


      I know that without the concatenation filter and a single input this script works fine, i'm having trouble working out how exactly I can work the concatenation filter into it, especially with the mapping command and how it works.



      If I try to run this script in it's current state I get the error:



      [hls @ 0x6a30180] Unable to find mapping variant stream

          I think I've found a solution, I added an extra filter that does the exact same thing and only mapped the filter outputs:

          If anyone knows any issues that this will cause, potential overhead, or any improvements what-so-ever I'd be happy to hear it.
