There is a little chance that user specified contradicted options
like -streaming 0 -ldash 1, however, it's more likely that user
didn't know or forgot to enable streaming for ldash. So enabling
streaming automatically to make the feature easier to use, similar
like enable FF_MOV_FLAG_FRAGMENT/EMPT
Try to make the feature easier to use, especially since the user
have enabled -strict experimental manually. The user shouldn't
be surprised that hls_playlist is enabled for lhls automatically,
so change the log level from warning to info for that.

It's not being used. For backward compatibility, AV_OPT_TYPE_RATIONAL
cannot be changed to use it.

All known encoders, etc. expect RPUs in this format, to my knowledge.
(There is no spec for parsing the RPUs, even privately, and not a single
piece of software that would benefit from that - and it is a legal minefield
which I am not going to touch.)

There are notes in each inividual patch.

Hi. I'm investigating in custom IO for HLS playing, and got errors while
calling segments.
I've compiled libav with `--disable-network` configure and tried custom IO by
overriding `io_open` and `io_close` for `AVFormatContext`. Everything goes well
until open segments urls.

The standard TS packet syntax and semantics are followed, noting the following
constraint:
- adaptation_field_control only the values "01" and "10
If original packet is corrupted, then parsed packet is probably corrupted too.
Let the application decide what to do.

to read/write JPEG XL image files.
