audio - Concat videos with ffmpeg does not work
2013-08
I'm currently trying to concat 3 Videos which don't have a audio stream and adding a audio file in the same step.
I created this command which should do the work:
ffmpeg -y -r 30 -i data\intro.mp4 -vcodec ppm -f image2pipe -i data\render.ppm -i data\outro.mp4 -i "data\I could be the one.mp3" -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -filter_complex "[0:0] [1:0] [2:0] concat=n=3:v=1:a=0 [v]" -map [v] -map 3:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4
It is indeed a long command but it satisfied my needs until I wanted to embend the actual video in between a intro and a outro.
I'm getting this log:

What should I do?
By the way: This is the command I used before and worked out great:
ffmpeg -y -r 30 -i "data\I could be the one.mp3" -vcodec ppm -f image2pipe -i data\render.ppm -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -map 1:0 -map 0:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4
Any ideas?
Well i solved it by splitting it into two commands:
ffmpeg -y -r 30 -i data\intro.mp4 -r 30 -i data\outro.mp4 -r 30 -vcodec ppm -f image2pipe -i data\render.ppm -filter_complex "[0:0] [2:0] [1:0] concat=n=3:v=1:a=0:unsafe=1 [v]" -c:v libx264 -preset ultrafast -map [v] data\tmp.mp4
ffmpeg -y -r 30 -i data\tmp.mp4 -i "data\I could be the one.mp3" -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a copy -map 0:0 -map 1:0 -shortest -metadata title="Development of BrainStoneMod" -metadata description="This is the development of the BrainStoneMod starting from 08th April, 2013" -metadata author="The_BrainStone" -metadata copyright="2013" -metadata year="2013" -metadata composer="" -metadata TBPM="" -metadata TDAT="" gource.mp4
But still, isn't there a possibility to do this in one???
I am trying to insert an audio channel with a video:
first of all I extract the audio from the original video for processing:
ffmpeg -i lotr.mp4 lotr.wav
I then extract all frames for later processing too:
ffmpeg -i lotr.mp4 -f image2 %d.jpg
When done processing audio and video streams, I try to create the video
ffmpeg -f image2 -r 15 -i %d.jpg new.mp4
then merge with the audio:
ffmpeg -i new.mp4 -i lotr.wav -map 0:0 -map 1:0 new_w_audio.mp4
Result: CPU activity = 100%, the process hangs and never returns. PS: I even tried it without modifying the images or the audio (so just trying to unpack then repack the video) but still the same output

Could be several things. A hang in general with video editing happens a lot when dealing with uncompressed video codecs. Not sure if I read up there that original video is in yuv420p codec. It maybe gets hanged trying to handle a lot of memory or when compressing directly the images to mp4. One thing I can think of is converting first to avi, ie, outputting to an avi but forcing a lossless codec like camtasia / camstudio (I think ffmpeg supports it) , so it is not so "heavy", and then do a second operation to convert to mp4. Other matter is... -r15 ? You surely know better which fps is having the original video, but it uses to be 24fps or so, isn't it?
Also... You might force as well the output codec, not just the format. MP4 works pretty well with .h264 codec, which gives a lot of quality and incredible small size. If I remember well ffmpeg also supports it. (you might want to try this first of all...)
Edit: Remember -codecs gives you the list of codecs, in command line. You can of course, for example in Win console, ffmpeg -codecs > codecs.txt for easier reading, searching etc. Healthy to do also with -formats, etc.
Try updating to the latest version of ffmpeg.
