New Issue with Joining Chunks with Mixdown Audio (Audio codec becomes FLAC regardless of choice) #8

Open eplipswich opened 6 years ago

eplipswich commented 6 years ago

This is the issue that I get from Joining Chunks with Mixdown Audio:

FFMpeg concat Exit code: 1

I believe the error in particular is this: Input #1, flac, from 'E:\Videos\New folder\untitled.aac':

Why does it use flac when I clearly chose aac?? The flac issue applies to any other video that I join chunks with mixdown audio for some reason (regardless of which video and audio formats I choose).

I really don't know, 😞. FFmpeg is being stupid 😠

This is what the Cmd looks like now:

> ffmpeg -f concat -safe 0 -i "path\to\chunklist.txt" -i "path\to\mixdown.aud" -c copy -map 0:v:0 -map 1:a:0 -t 00:03:28 "path\to\output.vid" -y

I tested AVI w/ Ac3 and it worked, I know Mp4 is more selective in what audio you can use w/ it, but I pretty sure AAC is one of them

For the time being, try using vid. conteiners like MKV and AVI.

rehdi93 commented 6 years ago

Even when I specified the correct audio codec w/ -c:a aac it still failed w/ the same error

Adding -strict -2 WILL work, but I don't know what those experimental open up to exactly. Could lead to even more unexpected behavior 😟

eplipswich commented 6 years ago

Why not use -map 0:v -map 1:a instead of -map 0:v:0 -map 1:a:0? That could work (I used -map 0:v -map 1:abefore and it worked perfect) . Like maybe use the same code as without mixdown audio.

I’ll try to test it out again on my side as well just to confirm.

eplipswich commented 6 years ago

Yeah, I tested with -map 0:v -map 1:a and it works perfect. The only other diff is that I put it in this order: -map 0:v -map 1:a -c copy and not the other way round like in your code.

Can you change it to that? Thanks :)

rehdi93 commented 6 years ago

Nope, tested MP4 + AAC, same error

DEBUG|ConcatCmd:  cmd:> ffmpeg -f concat -safe 0 -i "E:\Bibliotecas E\_projetos\Blender\Video\render\tests\chunks\chunklist.txt" -i "E:\Bibliotecas E\_projetos\Blender\Video\render\tests\test project2.aac" -map 0:v -map 1:a -c copy -t 00:03:28 "E:\Bibliotecas E\_projetos\Blender\Video\render\tests\test project2.mp4" -y
DEBUG|ConcatCmd:  ffmpeg exit code: 1

besides, I'm pretty sure -map 0:v -map 1:a is just shorthand for -map 0:v:0 -map 1:a:0

Can you post what your successful test looked like?

This was using the code ffmpeg -f concat -safe 0 -i chunklist.txt -i test.wav -map 0:v -map 1:a -c copy output.mp4

I'll test out aac in a bit.

So, just to revisit this issue, I think this is the solution:

ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a copy -map 0:v:0 -map 1:a:0 output.mp4

From https://superuser.com/questions/277642/how-to-merge-audio-and-video-file-in-ffmpeg

The key probably lies in -c:v and -c:a.
