For audio, it will select stream 3 from B. For subtitles, it will select stream 2 from B. For out3. The -map 1:a option will select all audio streams from the second input B. No other streams will be included in this output file. For the first two outputs, all included streams will be transcoded. The encoders chosen will be the default ones registered by each output format, which may not match the codec of the selected input streams.

For the third output, codec option for audio streams has been set to copy , so no decoding-filtering-encoding operations will occur, or can occur.

Packets of selected streams shall be conveyed from the input file and muxed within the output file. Although out1. The subtitle stream of C. However, in out2. The presence of -an disables audio stream selection for out2. The overlay filter requires exactly two video inputs, but none are specified, so the first two available video streams are used, those of A.

The output pad of the filter has no label and so is sent to the first output file out1. Due to this, automatic selection of the video stream is skipped, which would have selected the stream in B. The audio stream with most channels viz. The 2nd output file, out2. So, even though the first subtitle stream available belongs to C. The selected stream, stream 2 in B. The above command will fail, as the output pad labelled [outv] has been mapped twice. None of the output files shall be processed.

The video stream from B. Then a copy each is mapped to the first and third output files. The overlay filter, requiring two video inputs, uses the first two unused video streams. Those are the streams from A. The aresample filter is sent the first unused audio stream, that of A.

Since this filter output is also unlabelled, it too is mapped to the first output file. The presence of -an only suppresses automatic or manual stream selection of audio streams, not outputs sent from filtergraphs. Both these mapped streams shall be ordered before the mapped stream in out1. The video, audio and subtitle streams mapped to out2. Options which do not take arguments are boolean options, and set the corresponding value to true.

They can be set to false by prefixing the option name with "no". For example using "-nofoo" will set the boolean option with name "foo" to false. Some options are applied per-stream, e. Stream specifiers are used to precisely specify which stream s a given option belongs to. A stream specifier is a string generally appended to the option name and separated from it by a colon. Therefore, it would select the ac3 codec for the second audio stream.

A stream specifier can match several streams, so that the option is applied to all of them. An empty stream specifier matches all streams. For example, -codec copy or -codec: copy would copy all the streams without reencoding.

Matches the stream with this index. Stream numbering is based on the order of the streams as detected by libavformat except when a program ID is also specified. In this case it is based on the ordering of the streams in the program. Otherwise, it matches all streams of the specified type. Matches streams with the metadata tag key having the specified value.

If value is not given, matches streams that contain the given tag with any value. Matches streams with usable configuration, the codec must be defined and the essential information such as video dimension or audio sample rate must be present.

Show help. An optional parameter may be specified to print help about a specific item. If no argument is specified, only basic non advanced tool options are shown. Print complete list of options, including shared and private options for encoders, decoders, demuxers, muxers, filters, etc. Use the -decoders option to get a list of all decoders. Use the -encoders option to get a list of all encoders. Use the -formats option to get a list of all demuxers and muxers. Use the -formats option to get a list of all muxers and demuxers.

Use the -filters option to get a list of all filters. Use the -bsfs option to get a list of all bitstream filters. Use the -protocols option to get a list of all protocols. Show autodetected sources of the input device. Some devices may provide system-dependent source names that cannot be autodetected. The returned list cannot be assumed to be always complete. Show autodetected sinks of the output device. Some devices may provide system-dependent sink names that cannot be autodetected.

Indicates that repeated log output should not be compressed to the first line and the "Last message repeated n times" line will be omitted. Indicates that log output should add a [level] prefix to each message line. This can be used as an alternative to log coloring, e. Only show fatal errors which could lead the process to crash, such as an assertion failure.

This is not currently used for anything. Show all warnings and errors. Any message related to possibly incorrect or unexpected events will be shown.

Show informative messages during processing. This is in addition to warnings and errors. This is the default value. For example to enable repeated log output, add the level prefix, and set loglevel to verbose :. Another example that enables repeated log output without affecting current state of level prefix flag or loglevel :. By default the program logs to stderr. If coloring is supported by the terminal, colors are used to mark errors and warnings.

This file can be useful for bug reports. It also implies -loglevel debug. For example, to output a report to a file named ffreport. All FFmpeg tools will normally show a copyright notice, build options and library versions. This option can be used to suppress printing this information. Allows setting and clearing cpu flags. This option is intended for testing.

Override detection of CPU count. Exercise extreme caution when using this option. These options are provided directly by the libavformat, libavdevice and libavcodec libraries. To see the list of available AVOptions, use the -help option. They are separated into two categories:.

These options can be set for any container, codec or device. These options are specific to the given container, device or codec. For example to write an ID3v2. In the above example, a multichannel audio stream is mapped twice for output. The first instance is encoded with codec ac3 and bitrate k.

The second instance is downmixed to 2 channels and encoded with codec aac. A bitrate of k is specified for it using absolute index of the output stream. Force input or output file format. The format is normally auto detected for input files and guessed from the file extension for output files, so this option is not needed in most cases.

Set number of times input stream shall be looped. Loop 0 means no loop, loop -1 means infinite loop. Allow forcing a decoder of a different media type than the one detected or designated by the demuxer. Useful for decoding media data muxed as data streams. Select an encoder when used before an output file or a decoder when used before an input file for one or more streams.

When used as an input option before -i , limit the duration of data read from the input file. When used as an output option before an output url , stop writing the output after its duration reaches duration. Stop writing the output or reading the input at position. Set the file size limit, expressed in bytes. No further chunk of bytes is written after the limit is exceeded. The size of the output file is slightly more than the requested file size. When used as an input option before -i , seeks in this input file to position.

Note that in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. It works only on bit Mac OS. Be careful when you install the software and disable addons that you don't want!

Ich finde diese umgewandelte Dateie nirgendwo. Und hat er sich das umgewandeln? Was bedeutet eigentlich "Sequential encoding" oder " Multi file encoding?
