Overwrite audio on video

Audio Input Noise Measurer - An audio input device noise level measurer tool. Select 2 input audio channels and compare and measure their noise level. When recording audio from analog sources and have multiple recording devices this tool can be used to choose the device that is less noisy or determine audio level of a source.

This is an alias for -codec: For full manual control see the -map option. For each subtitle, wait for the next packet in the same stream and adjust the duration of the first to avoid overlap.

This is necessary with some subtitles codecs, especially DVB subtitles, because the duration in the original packet is only a rough estimate and the end is actually marked by an empty subtitle frame.

Failing to use this option when necessary can result in exaggerated durations or muxing failures due to non-monotonic timestamps. Note that this option will delay the output of all data until the next subtitle packet is decoded: Both indices start at 0.

The first -map option on the command line specifies the source for output stream 0, the second -map option specifies the source for output stream 1, etc. Overwrite audio on video - character before the stream identifier creates a "negative" mapping.

It disables matching streams from already created mappings. Note the map will still fail if an invalid input file index is used; such as if the map refers to a non-existent input. For example, to map ALL streams from the first input file to output ffmpeg -i INPUT -map 0 output For example, if you have two audio streams in the first input file, these streams are identified by "0: You can use -map to select which streams to place in an output file.

For example, assuming INPUT is a stereo audio file, you can switch the two audio channels with the following command: It is therefore not currently possible, for example, to turn two separate mono streams into a single stereo stream. However splitting a stereo stream into two single channel mono streams is possible.

If you need this feature, a possible workaround is to use the amerge filter. For example, if you need to merge a media here input. Note that those are file indices zero-basednot filenames. A metadata specifier can have the following forms: In an input metadata specifier, the first matching stream is copied from.

In an output metadata specifier, all matching streams are copied to. If metadata specifier is omitted, it defaults to global. These default mappings are disabled by creating any mapping of the relevant type.

A negative file index can be used to create a dummy mapping that just disables automatic copying. For example to copy metadata from the first stream of the input file to global metadata of the output file: If no chapter mapping is specified, then chapters are copied from the first input file with at least one chapter.

Use a negative file index to disable any chapter copying. Shows real, system and user time used and maximum memory consumption.

Maximum memory consumption is not supported on all systems, it will usually display as 0 if not supported. Mainly used to simulate a grab device, or live input stream e. Should not be used with actual grab devices or live input streams where it can cause packet loss.

By default ffmpeg attempts to read the input s as fast as possible. This option will slow down the reading of the input s to the native frame rate of the input s. It is useful for real-time output e. This option is deprecated, use -loop.

For compatibility reasons old values can be specified as numbers. Newly added values will have to be specified as strings always. This is the default method.Has severe recording gap issues. 5 min of video not saved, and missed the important part of an incident. gps stopped working.

software has the option for firmware update, thought this might solve the problem.
