You will need to have installed/enabled all the usual dvd support and proprietary codecs, etc. in myth control center. Sometimes this sort of ffmpeg thing is a missing library or codec that ffmpeg is looking for to do the particular encode. If it is in this case, then typing "ffmpeg" from a prompt may, in addition to listing all the options ffmpeg is compiled for, list one or another library it can't find for one of its compiled-in options. If this

Ffmpeg Tutorial
FFmpeg is based on the popular libavcodec and libavformat libraries that can be

found in many other video conversion applications, like Handbrake. So why would you need FFmpeg? Got a video in ffmpeg convert mkv to mp4 an obscure format that every other player couldn’t recognize? Transcode it with FFmpeg. Want to automate cutting video segments out of movies? Write a short batch script that uses FFmpeg. Where I work, https://ubuntuforums.org/showthread.php?t=1442434 I constantly have to encode and process video material, and I’d never want to go back to using a GUI tool for doing this. This post is a follow-up on Video Conversion done right: Codecs and Software, where I discussed the various codecs and containers that you can find these days. For a quick overview, I’d suggest to read this one as well, because it http://blog.superuser.com/2012/02/24/ffmpeg-the-ultimate-video-and-audio-manipulation-tool/ covers some important basics. Now, let’s dive into the more practical aspects. Installation FFmpeg is free and open source, and it’s cross-platform. You’ll be able to install it on your Windows PC as well as your Linux server. The only thing you need to be comfortable with is using your command line. As it's actively developed, you should try to update your version from time to time. Sometimes, new features are added, and bugs are fixed. You won't believe how many times updating FFmpeg solved encoding problems I had. Windows Compiling FFmpeg on Windows is not too easy. That’s why there are (semi-) automated builds of the latest version available online, most prominently the ones from Zeranoe.com. Download the latest build labeled as “static” for your 32 or 64 Bit system. Those builds work fairly well, but they might not include all possible codecs. For the commands where I used libfaac below, with the Zeranoe builds you have to choose another AAC codec instead, like libvo_aacenc, or aac, with the additional options -strict experimental. The Zeranoe download will include ffmpeg.exe, which is the main tool we are going to use. And you’re d

Concat protocol Concatenation of files with different codecs Concat filter Using an external script Pipe-friendly formats If you have media files with exactly the same codec and codec parameters you can concatenate them as described in "Concatenation of files with same codecs". If you have media with different codecs you can concatenate them as described in "Concatenation of files with different codecs" below. Concatenation of files with same codecs There are two methods within ffmpeg that can be used to concatenate files of the same type: the concat ''demuxer'' and the concat ''protocol''. The demuxer is more flexible - it requires the same codecs, but different container formats can be used; and it can be used with any container formats, while the protocol only works with a select few containers. However, the concat protocol is available in older versions of ffmpeg, where the demuxer isn't. Concat demuxer The concat demuxer was added to FFmpeg 1.1. You can read about it in the documentation. Instructions Create a file mylist.txt with all the files you want to have concatenated in the following form (lines starting with a # are ignored): # this is a comment file '/path/to/file1' file '/path/to/file2' file '/path/to/file3' Note that these can be either relative or absolute paths. Then you can stream copy or re-encode your files: ffmpeg -f concat -i mylist.txt -c copy output It is possible to generate this list file with a bash for loop, or using printf. Either of the following would generate a list file containing every *.wav in the working directory: # with a bash for loop for f in ./*.wav; do echo "file '$f'" >> mylist.txt; done # or with printf printf "file '%s'\n" ./*.wav > mylist.txt On Windows Command-line: (for %i in (*.wav) do @echo file '%i') > mylist.txt If your shell supports process substitution (like Bash and Zsh), you can avoid explicitly creating a list file and do the whole thing in a single line. This would be impossible with the concat protocol (see below). Make sure to generate absolute paths here, since ffmpeg will resolve paths relative to the list file your shell may create in a directory such as "/proc/self/fd/". ffmpeg -f concat -i <(for f in ./*.wav; do echo "file '$PWD/$f'"; done) -c copy output.wav ffmpeg -f concat -i <(printf "file '$PWD/%s'\n" ./*.wav) -c copy output.wav ffmpeg -f concat -i <(find . -name '*.wav' -printf "file '$PWD/%p'\n") -c copy output.wav You can also loop a video.
