Lost streams while using -map 0

Post by ngoral » Sat Mar 26, 2016 11:06 am

Hi!
I had a strange issue using ffmpeg on Ubuntu 14.04.
I run a command

Code: Select all

ffmpeg -i output2.avi -c:v h264 -minrate 2000k -maxrate 5000k -bufsize 2000k -profile:v high -level:v 4 -coder 1 -s 640x360 -bf 0 -pix_fmt yuv420p -r 25 -g 25 -c:a aac -ar 48k -b:a 321k -map 0 -y outpu.mp4
It provides such a usual output in console (already with -loglevel verbose):

it seems like it outputs all 3 audiostreams, but then i do

Code: Select all

ffmpeg -loglevel verbose -i outpu.mp4
And get only 2 audiostreams:

What's wrong with it?
It works fine on my Win machine, on virtual machine with Ubuntu on it, but as ran on real Ubuntu it behaves like this. Do you have any ideas?
Thanks!

that's odd that it would work on your windows box but not linux...

Anyway this is a clue:

Input stream #0:3 (audio): 0 packets read (0 bytes); 0 frames decoded (0 samples);

i've already asked the same on Stackoverflow.
And yes, I was told that the problem is in input three. And next we came to another question:
This file was generated by a command:

Code: Select all

ffmpeg -i input1.avi -i audio1.mp3 -t 00:00:20 -i audio2.aac -t 00:00:20 -c copy -map 0 -map 1 -map 2 -y output2.avi
And it was said to me that first -t is extra. But I still have a question why is it OK on Win and not OK on Ubuntu..
