I am trying to concatenate a couple of video files with ffmpeg for this i use
.././ffmpeg -i 01.mov -i op_IMG_20150221114715.mp4 -i 02.mov -i op_IMG_20150221114724.mp4 -i op_IMG_20150221114736.mp4 -strict -2 -filter_complex '[0:0] setsar=1/1[sarfix];[sarfix] [0:1] [1:0] [1:1] [2:0] [2:1] [3:0] [3:1] [4:0] [4:1] concat=n=5:v=1:a=1 [v] [a]' -map "[v]" -map "[a]" output.mp4
and it outputs this error

[Parsed_concat_1 # 0x7f922bc1cec0] Failed to configure output pad on Parsed_concat_1
The issue seems like I need to apply sarfix on input files 02.mov also. But I dont know the syntax for that.
Why some things must be set by the user
From the concat filter documentation:
All corresponding streams must have the same parameters in all
segments; the filtering system will automatically select a common
pixel format for video streams, and a common sample format, sample
rate and channel layout for audio streams, but other settings, such as
resolution, must be converted explicitly by the user.
More for the same docs:
For this filter to work correctly, all segments must start at
timestamp 0.
All of your inputs share the same parameters except for SAR (Sample [aka Pixel] Aspect Ratio) and frame rate. It is also always good practice to set the timestamps of all inputs to 0 (even if they already are at 0 it won't hurt to do so).
What you must do
Set timestamps to 0. The setpts filter will be used.
Two inputs have a SAR of 480:480, while the others has a SAR of 1:1. I'm not sure why they are set as 480:480 instead of 1:1. They all must either be 480:480 or 1:1. You can try both and see what looks best. The setsar filter will be used.
Two inputs have a frame rate of 24, one is 29.92, and one is 30. They all must have the same value, so the fps filter will be used.
Filtergraph syntax
A filtergraph is your complete filtering command. A filtergraph consists of filterchains. Filterchains consist of groups of filters connected via commas. Filterchains are connected via semicolons. The inputs and outputs of filterchains and filtergraphs can be named so they can be referenced by other filters or filterchains.
Basic filtergraph example
-filter_complex \
"[0:v]filter0,filter1,filter2[fc0]; \
[1:v]filter3,filter4,filter5[fc1]; \
[fc0][fc1]filter5[out]"
[0:v] refers to the video from the first input file.
[fc0] refers to the output from the first filterchain.
Actual filtergraph example
-filter_complex \
"[0:v]setsar=1/1,setpts=PTS-STARTPTS[v0]; \
[1:v]fps=24,setpts=PTS-STARTPTS[v1]; \
[2:v]setsar=1/1,setpts=PTS-STARTPTS[v2]; \
[3:v]fps=24,setpts=PTS-STARTPTS[v3]; \
[4:v]fps=24,setpts=PTS-STARTPTS[v4]; \
[v0][0:a][v1][1:a][v2][2:a][v3][3:a][v4][4:a]concat=n=5:v=1:a=1[v][a]"

I have an existing mp4 file and want to add an audio track to it using ffmpeg (the audio track is a wav file recorded from the device's microphone).
I'm executing the following command but it's not generating any output. It seems that fmpeg simply hangs:
String[] command = new String[]{"-i", audioFilePath, "-i", videoFilePath, "-codec", "copy", "-shortest", outputFilePath};
The logs are:

However Android devices cannot play this video and I don't understand exactly why and what I should change.
According to this Android Developer - Supported Media Formats I expected it to be supported
Any ideas?
I am trying to record from the video camera in my application. I have removed try/catch blocks and things of that nature to show an example of how to record:
camera.unlock();
mediaRecorder.setCamera(camera);
mediaRecorder.reset();
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
CamcorderProfile mCamcorderProfile = CamcorderProfile.get(CameraInfo.CAMERA_FACING_FRONT, CamcorderProfile.QUALITY_720P);
mediaRecorder.setProfile(mCamcorderProfile);
/*
mediaRecorder.setVideoEncodingBitRate(8000000);
mediaRecorder.setVideoEncodingBitRate(5000000);
mediaRecorder.setVideoEncodingBitRate(3000000);
*/
mediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface());
mRecFile = File.createTempFile("Video", ".mp4", mRecVideoPath);
mediaRecorder.setOutputFile(mRecFile.getAbsolutePath());
mediaRecorder.prepare();
mediaRecorder.start();
I record the video and it plays perfectly on the phone. Then I pull the video file off and I play it on a PC and the audio/video is slightly out of sync on a short 10 second clip. This only happens when recorded with a Samsung Note 3.
Just to be thorough, here is what I have tried:
Works perfectly on a Nexus 7
Works perfectly on a Samsung S3
Tried recording on two different Note 3
Tried various bitrates
For playing the out of sync video from the Note 3:
Played video on a Macbook pro, Chrome browser
Played video on a Macbook pro, quicktime
Played video on a Win7 pc
Out of sync on all of them.
When recording a video on the Note 3 with the stock camera app there is NO sync issue!
Update that I forgot: Using the highest quality setting I recorded a video with my app and one video with the stock camera. I inspected both videos and this is the output. I forget now which was which but the output is identical as far as I can tell.
