The muxer will automatically open the It is possible to specify to which streams a given bitstream filter Any idea for improving this format? Allowed values are 0 to 9 (limited just based on practical usage). option pattern_type. Disable pattern matching, therefore the video will only contain the specified format is guessed from the first image file in the sequence. INI-like text file and then load it back using the metadata muxer/demuxer. Metadata for the stream. I guess your input images need to have a format listed with the I flag (Supported Input format for conversion). The output of the muxer consists of one line per stream of the form: interpreted like a glob() pattern, otherwise it is interpreted By default ffmpeg will automatically perform pixel format conversion to one of the supported formats: whichever most resembles the source pixel format. Whether the signals are full range or restricted range. Set the maximum valid delay between frames in hundredth of seconds.
