• FFMPEG changes speed when concat 2 or more different videos

  13 novembre 2020, par Daniel Santos Neto

  I am using this code

  


  ffmpeg   -y  -re -i "/myvideos/countdown10.mp4"   -re -i "/myvideos/video_218.mp4"  -re -i "/myvideos/video_220.mp4"   -re -i "/myvideos/video_221.mp4"  -re -i "/myvideos/video_222.mp4"   -re -i "/myvideos/countdown10.mp4"  -re -i '/myvideos/watermark.png'  -filter_complex " [0:v] [0:a]   [1:v] [1:a]   [2:v] [2:a]   [3:v] [3:a]   [4:v] [4:a]   [5:v] [5:a]  concat=n=6:v=1:a=1:unsafe=1 [vv] [a]; [vv][6:v]overlay=W-w-0:0[v]" -map "[v]" -map "[a]"  -preset veryfast -vcodec h264 -acodec aac -strict -2 -max_muxing_queue_size 1024 -y -s 1280x720  -ar 44100 -f flv rtmp://server/live/5fa3731d4f8a6_159


  


  the problem is, when I run it the process speed is a lot faster then the videos length, so I got disconnected from my livestream before the live finishes.

  


  I guess it is something related to the bit rates.

  


  also I notice depends on what video is transcoding the speed floats between 0.9x and 3.7x

  


  frame= 4481 fps= 76 q=-1.0 Lsize= 16857kB time=00:03:13.21 bitrate= 714.7kbits/s dup=0 drop=393 speed=3.29x

  Also here is a video where you can see the process

  


  https://tutorials.avideo.com/video/102/ffmpeg-changes-speed-when-concat-2-or-more-different-videos

  


  this live should have exactly 40 seconds but finishes before then that

  


  also look at this time position https://tutorials.avideo.com/video/102/ffmpeg-changes-speed-when-concat-2-or-more-different-videos?t=12

  


  the speed changes from speed=0.9 to speed=1.9

  


  speed=0.9 to speed=1.9

  


  EDITED 2 :

  


  I tried the FPS command as suggested and still the problem

• FFMPEG - Multi Track, Multi Channel file to discrete mono files

  26 novembre 2020, par vade

  I have files which are multi track, and multi channel (ie, track 1 may be 5.1, track 2 may be stereo, track 3 may be stereo etc)

  


  I am looking to output every channel from every track into its own 'unrolled' discrete mono file.

  These files are vendor qualified masters, and the track / channel combinations vary between vendors, so some might be stereo, 5.1, 7.1 order, some might be all discrete mono already, some might be discrete stereo, 5.1, and mono tracks. Its all a mix. So im looking for some general strategy that gracefully handles all channels from all tracks.

  


  Now I have seen various strategies documented to handle discretizing audio via ffmpeg docs, but none of them seem to show how to target different channels from different tracks. Im sure its a pebkac error, but I'd love some guidance.

  


  I have tried both a map_channel approach as well as a -filtercomplex channelsplit approach.

  


  ffmpeg -i redacted.mxf -ss 60 \
-map_channel 0.1.0 -t 10 track_1_0.wav \
-map_channel 0.1.1 -t 10 track_1_1.wav \
-map_channel 0.1.2 -t 10 track_1_2.wav \
-map_channel 0.1.3 -t 10 track_1_3.wav \
-map_channel 0.1.4 -t 10 track_1_4.wav \
-map_channel 0.1.5 -t 10 track_1_5.wav \
-map_channel 0.2.0 -t 10 track_2_0.wav \
-map_channel 0.2.1 -t 10 track_2_1.wav \
-map_channel 0.3.0 -t 10 track_3_0.wav \
-map_channel 0.3.1 -t 10 track_3_1.wav \
-map_channel 0.4.0 -t 10 track_4_0.wav \
-map_channel 0.4.1 -t 10 track_4_1.wav 


  


  However, the output files are not all mono, some are marked as 5.1. I dont believe they are inheriting a sane / correct channel layout (mono) - but the output files that are marked 5.1 are nonsensical, as they are all sourced from stereo tracks. ie track_2_0.wav track_2_1.wav, track_3_0.wav, track_3_1.wav, track_4_0.wav, track_4_1.wav. Which seems odd. Track 1_0 from the above command outputs a sane media info :

Stream size                              : 938 KiB (100%)



  


  However the second and 3rd track have the wrong channel layout and an unexpected codec id :

  


  Format                                   : Wave
File size                                : 5.49 MiB

Bit depth                                : 16 bits
Stream size                              : 5.49 MiB (100%)



  


  Additionally re : map_channel, there are some docs that cast doubt that its the right approach :

  


  


  Note that currently each output stream can only contain channels from a single input stream ; you can’t for example use "-map_channel" to pick multiple input audio channels contained in different streams (from the same or different files) and merge them into a single output stream. It is therefore not currently possible, for example, to turn two separate mono streams into a single stereo stream. However splitting a stereo stream into two single channel mono streams is possible.

  


  


  Using filter complex, the docs/bug tracker have an example of discretizing 5.1 and marking mono. I can target the tracks I want, and get a valid filter chain as seen in debug log reporting, however I only get audio for the 1st track :

  


  ffmpeg -y -v 40 -i redacted.mxf -ss 60 \
    -disposition:a default \
    -filter_complex \
    "[0:a:0]channelsplit=channel_layout=5.1[c1][c2][c3][c4][c5][c6],\
    [c1]aformat=channel_layouts=mono[c1],\
    [c2]aformat=channel_layouts=mono[c2],\
    [c3]aformat=channel_layouts=mono[c3],\
    [c4]aformat=channel_layouts=mono[c4],\
    [c5]aformat=channel_layouts=mono[c5],\
    [c6]aformat=channel_layouts=mono[c6],\
    [0:a:1]channelsplit=channel_layout=stereo[c7][c8],\
    [c7]aformat=channel_layouts=mono[c7],\

    [c9]aformat=channel_layouts=mono[c9],\
    [c10]aformat=channel_layouts=mono[c10],\
    [0:a:3]channelsplit=channel_layout=stereo[c11][c12],\
    [c11]aformat=channel_layouts=mono[c11],\
    [c12]aformat=channel_layouts=mono[c12]"\
     -map  "[c1]" -t 10 1.wav\
     -map  "[c2]" -t 10 2.wav\
     -map  "[c3]" -t 10 3.wav\
     -map  "[c4]" -t 10 4.wav\
     -map  "[c5]" -t 10 5.wav\
     -map  "[c6]" -t 10 6.wav\
     -map  "[c7]" -t 10 7.wav\
     -map  "[c8]" -t 10 8.wav\
     -map  "[c9]" -t 10 9.wav\
     -map  "[c10]" -t 10 10.wav\
     -map  "[c11]" -t 10 11.wav\
     -map  "[c12]" -t 10 12.wav


  


  TL/DR ;

  


  In short, how does one export every channel of every track as a discrete mono audio track (regardless of the channel layouts ?)

  


  Thank you !

  


• ffmpeg : problems playing video on android

  25 novembre 2020, par Jonathan García

  (Translated) Hello ! I have the following problem. I concatenate multiple ts files and convert to mp4 with ffmpeg. I do this operation multiple times in an automated way, so I don't always check the results, but whenever I do, on the computer, the result obtained is as expected. However, some videos, when played on an Android device, are seen incorrectly in any application : Chrome, Firefox, Vlc, etc. The version of ffmpeg I use is the latest. This is the command I use :

  


  ffmpeg.exe -hwaccel dxva2 -y -f concat -i list.txt -acodec copy -vcodec copy output.mp4 -preset normal

  


  Results :

  Not all videos are "yuv420p (tv, unknown / bt470bg / unknown, progressive)", but this should not be the problem, since other videos with this information are seen correctly on Android.

  


  To correct this type of video I do the following :

  


  ffmpeg -y -f concat -i list.txt -c:v libx264 -preset slow -crf 22 -pix_fmt yuv420p -c:a aac -b:a 128k output.mp4

  


  So I get the video to play correctly both on pc and Android. Unfortunately, automating the process by always using this last line occasionally causes problems (starting file 40MB, ending file> 1GB, more than 2 hours)

  


  I would like, if possible, help me identify which videos will be viewed incorrectly on Android. Thank you very much in advance. Finally, this is the answer that ffmpeg gives when executing the line with which I fix the file :
