pub const AVFMT_NOFILE: i32 = 0x0001;Expand description
AVFMT_NOFILE — AVOutputFormat flag indicating the muxer manages its own
I/O and has no AVIOContext (pb) opened by the caller.
Set for muxers such as image2 (image sequences), hls, dash, and similar
segment/directory formats. When set, the caller must not avio_open a pb,
and the owned OutputFormatContext must not
close one on drop.
