This useful, because by ffprobe's very nature, you use it to probe a file and find out what it is. Requiring every format private option to be known to the demuxer forces one to run ffprobe twice, if one wants to use ffprobe in a generic way. For example, say one wants to probe all user-uploaded files, while also ignoring edit lists for any MP4s that are uploaded. Currently, you'd have to run ffprobe twice: once to identify the format, and once again to actually probe the metadata you want. After this patch, you could set -ignore_editlist 1 on every call and only probe once. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
