If the space reserved is insufficient, muxing will fail. You may use multiple stream specifiers separated by commas (,) e.g. Enable (1) or disable (0) storing all segments in one file, accessed using byte ranges. indexed by sequential numbers. Specify the number of fragments kept in the manifest. If var_stream_map is not set, then the "$ext$" is replaced with the file name extension specific for the segment format. To ensure all the streams are interleaved correctly, libavformat will Use wallclock as timestamps if set to 1. will output a packet regardless of whether it has queued a packet for all line of the script. Similarly, other losses occur when converting from some formats to other formats. It creates a playlist file, and one or more segment files. init_context_defaults () audio and video, and store it in the file out.md5: You can print the MD5 to stdout with the command: The mov/mp4/ismv muxer supports fragmentation.

If the space reserved is insufficient, muxing will fail. You may use multiple stream specifiers separated by commas (,) e.g. Enable (1) or disable (0) storing all segments in one file, accessed using byte ranges. indexed by sequential numbers. Specify the number of fragments kept in the manifest. If var_stream_map is not set, then the "$ext$" is replaced with the file name extension specific for the segment format.
