∟SWF Files for Video and Audio Streams

This chapter provides tutorial notes and example codes on SWF files for video and audio streams. Topics include SWF file structure for video and/or audio streams; installing FFmpeg to manipulate video/audio streams; 'ffprobe' to view video/audio stream properties; 'ffplay' to play stream SWF files; 'ffmpeg' to convert other stream format to SWF, break long streams into parts, concatenate short streams, split/merge streams, reduce resolution and frame rate.

Conclusions:

Video and audio data can be streamed in SWF files.
FFmpeg is an excellent tool to manipulate video and audio streams stored in SWF format and many other formats.
"ffmpeg" command can convert video and audio streams in SWF file from or to other file formats.
"ffprobe" command can print out video and audio stream properties.
"ffplay" command can play video and audio stream SWF files
"ffmpeg ... -ss ... -to ..." command can break a long stream into shorter parts.
"ffmpeg ... -filter_complex ... concat ..." command can concatenate short streams into a longer stream.
"ffmpeg ... -map ..." command can split a video or audio stream into a separate file, or merge them back.
"ffmpeg ... -s ..." command can reduce video frame resolution.
"ffmpeg ... -r ..." command can reduce video frame rate.
