FFMPEG SAR mismatch when concatenating videos
6 septembre 2020, par marcmanI'm trying to concatenate videos with different codecs using the
concat
filter. I'm also doing a bunch of processing to scale and pad the individual clips in this filter as well. However, I keep getting an error of this form :

[Parsed_concat_14 @ 0x556b918ed580] Input link in1:v0 parameters (size 960x1280, SAR 0:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 1:1)



Here is my command :


ffmpeg \
 -y \
 -loglevel warning \
 -stats \
 -i videos/vid0.mp4 \
 -i videos/vid1.mp4 \
 -i videos/vid2.mov \
 -filter_complex \
"[0:v]setpts=PTS-STARTPTS, scale=1920:1080, setsar=1, drawtext=expansion=strftime: basetime=$(date +%s -d'2020-07-10 16:04:44')000000 : fontcolor=white : text='%^b %d, %Y%n%l\\:%M%p' : fontsize=36 : y=1080-4*lh : x=1920-text_w-2*max_glyph_w; \
[1:v]setpts=PTS-STARTPTS, scale=810:1080, pad=width=1920:height=1080:x=555:y=0:color=black, setsar=1, drawtext=expansion=strftime: basetime=$(date +%s -d'2020-08-20 21:12:27')000000 : fontcolor=white : text='%^b %d, %Y%n%l\\:%M%p' : fontsize=36 : y=1080-4*lh : x=1365-text_w-2*max_glyph_w; \
[2:v]setpts=PTS-STARTPTS, scale=607:1080, pad=width=1920:height=1080:x=656:y=0:color=black, setsar=1, drawtext=expansion=strftime: basetime=$(date +%s -d'2020-08-27 16:42:26')000000 : fontcolor=white : text='%^b %d, %Y%n%l\\:%M%p' : fontsize=36 : y=1080-4*lh : x=1263-text_w-2*max_glyph_w; \
[0:v][0:a][1:v][1:a][2:v][2:a]concat=n=3:v=1:a=1[v][a]" \
 -map "[v]" \
 -map "[a]" \
 videos.mp4



This gives the following error :


[Parsed_concat_14 @ 0x563ab9d840c0] Input link in1:v0 parameters (size 960x1280, SAR 0:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 1:1)
[Parsed_concat_14 @ 0x563ab9d840c0] Input link in2:v0 parameters (size 1080x1920, SAR 0:1) do not match the corresponding output link in0:v0 parameters (1280x720, SAR 1:1)



The input videos have these resolutions :


- 

- vid0.mp4 : (1280x720)
- vid1.mp4 : (960x1280)
- vid2.mp4 : (1080x1920)








The output resolution of the concatenated output is to be 1920x1080.


I've added the
setsar=1
command after all my scaling and padding operations, as per this question and answer. I've also triedsetdar=16/9
as in this answer, but it made no difference.

What am I missing here ?

Finding File Matches & Variable Assignment using a .BAT Script
6 octobre 2019, par A Person — batch-file, ffmpegI am trying to assign a file to a variable in a batch-file and then also assign another 2 files into anoter variable.
However, I am having an issue.
From research, I found how I can do the assigning but does anyone know how I can do the below.
From a folder or text file, (either is fine), find the
.m2v
video file and assign that toVar1
then find matching audio in.wav
and put that inVar2
and the third is also an audio.wav
with mathcing name and assign that toVar3
.The problem I am having is trying to find the matching
2
audio files to the video.The video file is named as :
PAV_PRG_13683Highc450277201906251802090353.m2v
Audio 1 is :
PAV_PRG_13683High01c450211201906251802090376.wav
Audio 2 is :
PAV_PRG_13683High00c450211201906251802090368.wav
The file name matches until it sees the word
High
. Everything afterHigh
is not needed, (it is just a random string), so trying to match is an issue.Is there a way to find the match by comparing everything before
High
.Also as I will be using the variable and putting them through ffmpeg to merge, is there way to do it so that when the
ffmpeg
command has completed, it moves to the next matching files and assigns them to the variable.The files are store in
2
folders, one folder has all the video files*.m2v
and another folder has all the*.wav
audio files in pairs of2
. Each video has exactly2
audios, (left right).is there any help on this subject, I have already come up empty in my research and have been checking for this over the last week spent almost 30 hours.
