Concat failing with ffmpeg 5.0 vs ffmpeg 4.1.1
16 avril 2022, par WoolwitI have ffmpeg 5.0 installed on a new Silicon M1 Mac Mini running Monterey and concat is failing with the same command that has served me well on ffmpeg 4.1.1 lo, all these many years. Anyone have an idea why this command would fail on the newer version of ffmpeg.
This is with the exact same mp4 files. The ffmpeg 4.1.1. completes the concat in less than a minute.


ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4



Thank you !

FFmpeg not cropping video correctly
7 avril 2022, par user973254I'm using ffmpeg as :


ffmpeg -i "video.webm" -c:v libx264 -vf "crop=in_w:in_h:in_w/2:in_h" -ss 00:02:56.000 -to 00:03:02.750 cut.mp4 -y


to get left side of screen to crop out right one, but in result I'm getting uncropped video (both sides present), when I change command to get right side (to crop out left one) :


ffmpeg -i "video.webm" -c:v libx264 -vf "crop=in_w/2:in_h:in_w:in_h" -ss 00:2:56.000 -to 00:03:02.750 cut.mp4 -y


everything works as it should (only right side of original video presents in "cut.mp4").


What am I doing wrong ?


P.S.

FFMPEG atempo introducing phasing for multichannel mono audio tracks
27 septembre 2021, par BrainNoWerkIs this a bug, or expected behaviour ? When converting materials from PAL to NTSC I invoke atempo as follows :


-map 0:a:? -af atempo=24000/25025 ^
-c:a pcm_s24le


I use this in a windows batch file (hence the caret) as a catch-all for all files that need to be converted, not having to deal with how many audio channels might be present or in what order.


However, when my input was a broadcast MXF with 10channel mono audio (1 per stream) it introduced wild phasing between the tracks.


Merging the tracks into a single stream to be processed by atempo resulted in no phasing.


-filter_complex "[0:a:0][0:a:1][0:a:2][0:a:3][0:a:4][0:a:5][0:a:6][0:a:7][0:a:8][0:a:9] amerge=inputs=10, atempo=24000/25025[FRC]" ^
-map "[FRC]" -c:a pcm_s24le


Is this expected behaviour ? I can't see any documentation detailing the need to first use amerge before invoking atempo.


If indeed this step is necessary, is there a way to "wildcard" the amerge operation so that I don't have to manually enter all the audio channels, and then the "inputs=" ? This would allow me to make it more universal.


This is my first question on stack overflow, so please be gentle. I've come here to find so many answers to my FFMPEG questions in the past—but this seems to be an edge case I can't get much detail on.


Thanks !


EDIT :


This output using the wildcard produces phasing :

Let me know if you need more detail than what I've provided.


Tangential questions related to this job and potentially not worth their own thread, even though I've looked extensively and not found the answers (happy to post them individually if that's necessary) :


- 

-
I can't seem to split any portion of the filter_complex above with a caret (^) within a windows batch file (no number of spaces before or after resolve this issue). It breaks the chain and the filter graphs complain of no input.


-
Is FFMBC still the only way to include broadcast closed captioning ? This functionality doesn't exist within FFMPEG ?
