FFMPEG recode clip1 to match clip2 for concat demux
21 novembre 2020, par Gert GottschalkI want to concat two video clips using ffmpeg concat. To use concat demuxer both should have same codec settings. clip2 is much shorter so I want to recode it to match clip1. Initially clip2 had tbn not matching and I adjusted that with '-video_track_timescale 50000'. Still the concat video after the cut into clip2 is garbled (audio seems OK)


This is what ffprobe tells for clip1 :

Then for concat :


/home/tools/bin/ffmpeg -f concat -i list.files -y clip12.mp4


The only gap is with
clip1 : 2080 kb/s
clip2 : 1553 kb/s


Is that significant ?


If yes, how to recode clip2 to match and result in concat clip12 being clean ?


EDIT (Per feedback from llogan) :


Probing input clips with latest ffprobe.

I'm observing mismatch in what I assume is the audio channel.

Probably need to match audio channel. I noticed that the concat too a long time. I was expecting the concat to just do copying and not re-rendering.

FFMPEG-PHP Error "Sample rate index in program config element does not match the sample rate index configured by the container."
21 novembre 2020, par JonathanAm using FFMPEG installed on a Windows server. I have a PHP webpage that uploads and trims videos using FFMPEG, when I upload MP4's with AAC audio, especially videos over 100mb, I get the following errors in the log output below.


I was wondering if anyone could point me in the right direction to getting this resolved.

FFMPEG - Multi Track, Multi Channel file to discrete mono files
26 novembre 2020, par vadeI 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
pebkacerror, but I'd love some guidance.

I have tried both a
map_channelapproach as well as a-filtercomplex channelsplitapproach.

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 :


File size : 938 KiB

Overall bit rate mode : Constant
Overall bit rate : 768 Kbps

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


Format : Wave

Overall bit rate : 4 608 Kbps

Channel(s) : 6 channels
Channel layout : L R C LFE Lb Rb
Sampling rate : 48.0 KHz
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],\

 [c3]aformat=channel_layouts=mono[c3],\

 [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 !
