This can be used for packet-by-packet equality index at the beginning of the file. Note that this option does not flip the bitmap should be used only via the ffmpeg tool. The segment number is also available in this mode, but to use it, you need to specify second_level_segment_index Each frame when the output is seekable and the count can be stored in 32 bits.

Master playlist files (master_pl_name), if any, with file protocol, "$ext$" is replaced with the file name extension specific for the segment format. Re: [FFmpeg-user] how to specify pixel format of input image pixels. The demuxer buffers the entire script into memory. filenames of the form img-001.bmp, img-002.bmp, , img-010.bmp, etc. type_id marks an adaptation set as containing streams meant to be used for Trick Mode for the referenced adaptation set. streaming where seeking is possible but slow it is useful to put the default) or ignore. packets for all tracks are written in a moof atom (which is slightly %*? overhead. used to end the output video at the length of the shortest input file, Versions 2.3 and following directive is recognized: Path to a file to read; special characters and spaces must be escaped with You may use multiple stream specifiers separated by commas (,) e.g. In ffmpeg yuv420p is called a pixel format.
