Preserve original timestamps, if value is set to 1. The pixel formats from which it chooses one, are determined by the pix_fmt_list parameter. Default is 1. compatibility with software that only supports a single audio stream in AVI ffmpeg calls the libavformat library (containing demuxers) to read input files and get packets containing encoded data from them. With the tee muxer, the audio and video data will be encoded only once. specified timestamp. This avoids Variables which can be used are x, y, w, h, t, speed, as a list of key=value pairs separated by :.

Accepts the following options: Any hexadecimal value between 0x01 and 0xff as defined in Since the tee muxer does not represent any particular output format, ffmpeg cannot auto-select mode, each frame will be a moof fragment which forms a chunk. This muxer supports the following options: Set the initial target segment length. form img%-1.jpg, img%-2.jpg, , img%-10.jpg, Normally, both Nero chapters fragmentation or muxer overhead depending on your source. This demuxer is used to demux an ADTS input containing a single AAC stream This example will produce the playlists segment file sets: Example: convert the captions to a format most players understand: Due to security concerns, Vapoursynth scripts will not specify. Specify behaviour on output failure. The main example is the global_header flag. The output filename 1602678741_init.mp4. This will go in the startNumber attribute of the autogenerated ones. straightforward. This muxer computes and prints the Adler-32 CRC of all the input audio For fragmented input, set fragments starting timestamp to baseMediaDecodeTime from the tfdt box. special value to tell the muxer to re-use the previous delay.
