To show all the entries in the section "format", but only the codec type in the section "stream", specify the argument:

format : stream=codec_type

FFMPEG ffprobe Documentation 3 Options 3.3 AVOptions

All codec AVOptions are per-stream, and thus a stream specifier should be attached to them:

ffmpeg -i multichannel.mxf -map 0:v:0 -map 0:a:0 -map 0:a:0 -c:a:0 ac3 -b:a:0 640k -ac:a:1 2 -c:a:1 aac -b:2 128k out.mp4

FFMPEG ffprobe Documentation 15 Demuxers 15.8 flv, live_flv, kux

This demuxer is used to demux FLV files and RTMP network streams. In case of live network streams, if you force format, you may use live_flv option instead of flv to survive timestamp discontinuities. KUX is a flv variant used on the Youku platform.

ffmpeg -f flv -i myfile.flv ...
ffmpeg -f live_flv -i rtmp://<any.server>/anything/key ....

FFMPEG ffprobe Documentation 18 Protocols 18.14 http

If set to 1 enables experimental HTTP server. This can be used to send data when used as an output option, or read data from a client with HTTP POST when used as an input option. If set to 2 enables experimental multi-client HTTP server. This is not yet implemented in ffmpeg.c and thus must not be used as a command line option.

# Server side (sending):
ffmpeg -i somefile.ogg -c copy -listen 1 -f ogg http://server:port

# Client side (receiving):
ffmpeg -i http://server:port -c copy somefile.ogg

# Client can also be done with wget:
wget http://server:port -O somefile.ogg

# Server side (receiving):
ffmpeg -listen 1 -i http://server:port -c copy somefile.ogg

# Client side (sending):
ffmpeg -i somefile.ogg -chunked_post 0 -c copy -f ogg http://server:port

# Client can also be done with wget:
wget --post-file=somefile.ogg http://server:port
