-@chapter Description -@c man begin DESCRIPTION - -avconv is a very fast video and audio converter that can also grab from -a live audio/video source. It can also convert between arbitrary sample -rates and resize video on the fly with a high quality polyphase filter. - -avconv reads from an arbitrary number of input "files" (which can be regular -files, pipes, network streams, grabbing devices, etc.), specified by the -@code{-i} option, and writes to an arbitrary number of output "files", which are -specified by a plain output filename. Anything found on the command line which -cannot be interpreted as an option is considered to be an output filename. - -Each input or output file can in principle contain any number of streams of -different types (video/audio/subtitle/attachment/data). Allowed number and/or -types of streams can be limited by the container format. Selecting, which -streams from which inputs go into output, is done either automatically or with -the @code{-map} option (see the Stream selection chapter). - -To refer to input files in options, you must use their indices (0-based). E.g. -the first input file is @code{0}, the second is @code{1} etc. Similarly, streams -within a file are referred to by their indices. E.g. @code{2:3} refers to the -fourth stream in the third input file. See also the Stream specifiers chapter. - -As a general rule, options are applied to the next specified -file. Therefore, order is important, and you can have the same -option on the command line multiple times. Each occurrence is -then applied to the next input or output file. -Exceptions from this rule are the global options (e.g. verbosity level), -which should be specified first. - -Do not mix input and output files -- first specify all input files, then all -output files. Also do not mix options which belong to different files. All -options apply ONLY to the next input or output file and are reset between files. - -@itemize -@item -To set the video bitrate of the output file to 64kbit/s: -@example -avconv -i input.avi -b 64k output.avi -@end example - -@item -To force the frame rate of the output file to 24 fps: -@example -avconv -i input.avi -r 24 output.avi -@end example - -@item -To force the frame rate of the input file (valid for raw formats only) -to 1 fps and the frame rate of the output file to 24 fps: -@example -avconv -r 1 -i input.m2v -r 24 output.avi -@end example -@end itemize - -The format option may be needed for raw input files. - -@c man end DESCRIPTION - -@chapter Stream selection -@c man begin STREAM SELECTION - -By default avconv tries to pick the "best" stream of each type present in input -files and add them to each output file. For video, this means the highest -resolution, for audio the highest channel count.

This is especially true for RealVideo where -the Linux player does not seem to be very fast, so it can miss -frames. An example is: - -@example -avconv -g 3 -r 3 -t 10 -b 50k -s qcif -f rv10 /tmp/b.rm -@end example - -@item -The parameter 'q' which is displayed while encoding is the current -quantizer. The value 1 indicates that a very good quality could -be achieved. The value 31 indicates the worst quality. If q=31 appears -too often, it means that the encoder cannot compress enough to meet -your bitrate. You must either increase the bitrate, decrease the -frame rate or decrease the frame size. - -@item -If your computer is not fast enough, you can speed up the -compression at the expense of the compression ratio. You can use -'-me zero' to speed up motion estimation, and '-intra' to disable -motion estimation completely (you have only I-frames, which means it -is about as good as JPEG compression). - -@item -To have very low audio bitrates, reduce the sampling frequency -(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3). - -@item -To have a constant quality (but a variable bitrate), use the option -'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst -quality). - -@end itemize -@c man end TIPS - -@chapter Examples -@c man begin EXAMPLES - -@section Preset files - -A preset file contains a sequence of @var{option=value} pairs, one for -each line, specifying a sequence of options which can be specified also on -the command line. Lines starting with the hash ('#') character are ignored and -are used to provide comments. Empty lines are also ignored. Check the -@file{presets} directory in the Libav source tree for examples. - -Preset files are specified with the @code{pre} option, this option takes a -preset name as input. Avconv searches for a file named @var{preset_name}.avpreset in -the directories @file{$AVCONV_DATADIR} (if set), and @file{$HOME/.avconv}, and in -the data directory defined at configuration time (usually @file{$PREFIX/share/avconv}) -in that order. For example, if the argument is @code{libx264-max}, it will -search for the file @file{libx264-max.avpreset}. - -@section Video and Audio grabbing - -If you specify the input format and device then avconv can grab video -and audio directly. - -@example -avconv -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg -@end example - -Note that you must activate the right video source and channel before -launching avconv with any TV viewer such as -@uref{http://linux.bytesex.org/xawtv/, xawtv} by Gerd Knorr. You also -have to set the audio recording levels correctly with a -standard mixer. - -@section X11 grabbing - -Grab the X11 display with avconv via - -@example -avconv -f x11grab -s cif -r 25 -i :0.0 /tmp/out.mpg -@end example - -0.0 is display.screen number of your X11 server, same as -the DISPLAY environment variable. - -@example -avconv -f x11grab -s cif -r 25 -i :0.0+10,20 /tmp/out.mpg -@end example - -0.0 is display.screen number of your X11 server, same as the DISPLAY environment -variable. 10 is the x-offset and 20 the y-offset for the grabbing. - -@section Video and Audio file format conversion - -Any supported file format and protocol can serve as input to avconv: - -Examples: -@itemize -@item -You can use YUV files as input: - -@example -avconv -i /tmp/test%d.Y /tmp/out.mpg -@end example - -It will use the files: -@example -/tmp/test0.Y, /tmp/test0.U, /tmp/test0.V, -/tmp/test1.Y, /tmp/test1.U, /tmp/test1.V, etc... -@end example - -The Y files use twice the resolution of the U and V files. They are -raw files, without header. They can be generated by all decent video -decoders. You must specify the size of the image with the @option{-s} option -if avconv cannot guess it. - -@item -You can input from a raw YUV420P file: - -@example -avconv -i /tmp/test.yuv /tmp/out.avi -@end example - -test.yuv is a file containing raw YUV planar data. Each frame is composed -of the Y plane followed by the U and V planes at half vertical and -horizontal resolution. - -@item -You can output to a raw YUV420P file: - -@example -avconv -i mydivx.avi hugefile.yuv -@end example - -@item -You can set several input files and output files: - -@example -avconv -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg -@end example - -Converts the audio file a.wav and the raw YUV video file a.yuv -to MPEG file a.mpg. - -@item -You can also do audio and video conversions at the same time: - -@example -avconv -i /tmp/a.wav -ar 22050 /tmp/a.mp2 -@end example - -Converts a.wav to MPEG audio at 22050 Hz sample rate. - -@item -You can encode to several formats at the same time and define a -mapping from input stream to output streams: - -@example -avconv -i /tmp/a.wav -map 0:a -b 64k /tmp/a.mp2 -map 0:a -b 128k /tmp/b.mp2 -@end example - -Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map -file:index' specifies which input stream is used for each output -stream, in the order of the definition of output streams. - -@item -You can transcode decrypted VOBs: - -@example -avconv -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi -@end example - -This is a typical DVD ripping example; the input is a VOB file, the -output an AVI file with MPEG-4 video and MP3 audio. Note that in this -command we use B-frames so the MPEG-4 stream is DivX5 compatible, and -GOP size is 300 which means one intra frame every 10 seconds for 29.97fps -input video. Furthermore, the audio stream is MP3-encoded so you need -to enable LAME support by passing @code{--enable-libmp3lame} to configure. -The mapping is particularly useful for DVD transcoding -to get the desired audio language. - -NOTE: To see the supported input formats, use @code{avconv -formats}. - -@item -You can extract images from a video, or create a video from many images: - -For extracting images from a video: -@example -avconv -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg -@end example - -This will extract one video frame per second from the video and will -output them in files named @file{foo-001.jpeg}, @file{foo-002.jpeg}, -etc. Images will be rescaled to fit the new WxH values. - -If you want to extract just a limited number of frames, you can use the -above command in combination with the -vframes or -t option, or in -combination with -ss to start extracting from a certain point in time. - -For creating a video from many images: -@example -avconv -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi -@end example - -The syntax @code{foo-%03d.jpeg} specifies to use a decimal number -composed of three digits padded with zeroes to express the sequence -number. It is the same syntax supported by the C printf function, but -only formats accepting a normal integer are suitable. - -@item -You can put many streams of the same type in the output: - -@example -avconv -i test1.avi -i test2.avi -map 0.3 -map 0.2 -map 0.1 -map 0.0 -c copy test12.nut -@end example - -The resulting output file @file{test12.avi} will contain first four streams from -the input file in reverse order. - -@end itemize -@c man end EXAMPLES - -@include eval.texi -@include encoders.texi -@include demuxers.texi -@include muxers.texi -@include indevs.texi -@include outdevs.texi -@include protocols.texi -@include bitstream_filters.texi -@include filters.texi -@include metadata.texi - -@ignore - -@setfilename avconv -@settitle avconv video converter - -@c man begin SEEALSO -ffplay(1), ffprobe(1), ffserver(1) and the FFmpeg HTML documentation - -@c man end - -@c man begin AUTHORS -The Libav developers -@c man end - -@end ignore - -@bye |
