If you meant you want to concatenate them, the FAQ has instructions. The "-newvideo", "-newaudio" and "-newsubtitle" options have to be specified immediately after the name of the output file to which you want to add them.

In addition to the first video and audio streams, the resulting channel 1 is front left, channel 2 is front center.etc. Source audio is LPCM 24-bit, 48kHz signed little endian, and I am exporting the same. Ive written a bash script using FFmpeg that processes as source a broadcast quality ProRes (HQ) file with four mono tracks of audio. vcodec copy -acodec copy test12.avi -newvideo -newaudio the first warning means one of the wav inputs has no channel layout defined i.e. Audio clipping after amerge in FFmpeg 1 Hoping someone out there can help me with this audio issue Im having using FFmpeg. You can put many streams of the same type in the output: ffmpeg -i test1.avi -i test2.avi -vcodec copy -acodec copy \ (I gave up getting the patches into ffmpeg) - ffmpeg/afamerge.

If you are on Windows you can use YAMB which is a GUI for MP4Box that works great:įFmpeg has added a concatenation filter, more info here:įrom the ffmpeg man page "Examples" section: Branch of ffmpeg with support for features needed by VideoProcessor. It is available for Windows, Linux and OS X: You can check whether you have the real ffmpeg by running ffmpeg and checking if the first output line ends with "the FFmpeg developers".įorget about FFmpeg, use MP4Box instead, it is easy and faster: mp4box -add video1.mp4 -cat video2.mp4 -cat video3.mp4 output.mp4 This won't work with avconv, so in such a case you have to compile ffmpeg yourself. amerge on the other hand is used to combine two or more inputs, merging two mono streams into a single stereo stream, for example. Note: some distributions (like Ubuntu) do not have ffmpeg in their repository and instead define ffmpeg to be an alias of avconv. Audio clipping after amerge in FFmpeg 1 Hoping someone out there can help me with this audio issue Im having using FFmpeg. A good place to start is the documentation: amix / amerge In short, amix mixes two or more inputs into one output, an example would be adding commentary on top of gameplay audio.
