(FFMPEG) Muxing h264 and aac

[Simon_]

Hello all,

I am trying to mux h246 and aac with FFMPEG, When i do try to do this FFMPEG states

video.h264: Invalid data found when processing input

I have tried to use YAMB to mux it and it says the it cannot find the H264 start code.

How can I mux the 2 files in FFMPEG.

If the elementary stream is corrupted or broken, it's natural that the muxing applications will reject it.

BTW, how did you obtain the problematic .264 video --- did you encode it, or did you demux it from another file?

perhaps?

I am converting multiple VOB files like this:

Step 1:

ffmpeg -i VTS_01_4.vob -c:v libx264 -c:a aac -strict experimental VTS_01_4.mp4

Step 2:
Create a text file and include the paths and names of each file to concatenate (or "join"). Example file,
input.txt:

file '/home/jenia/input1.mp4'
file '/home/jenia/input2.mp4'
file '/home/jenia/input3.mp4'

Step 3.
Now you can use concat


ffmpeg -f concat -i input.txt -codec copy output.mp4

Step 4.
Deinterlace

ffmpeg -i input.mp4 -vf "yadif=0:-1:0, scale=trunc(iw/2)*2:trunc(ih/2)*2" -strict -2 output.mp4

So all i need to do is swap out the aac audio, any ideas on what I have done wrong?

why not convert them with mencoder which can load specific titles from a DVD or if for some unknown reason ffmpeg needs to be used use the 'contant-textfile-'trick directly with the vob files
(also the whole reencoding and after reencoding reencode again to deinterlace seems like a huge mistake if quality is of any concern,...)
