Only ac3dec and dcadec use it.

Those decoders have been switched to float output and so do not use
fmtconvert anymore.

Don't prefix them ffio_url, which is misleading, sounding too
much like the urlprotocol layer (like ffurl_*).

Incidentally `-y` also collides with avconv global options.

Update x11grab to match and document the option.

Many of these functions were named foo_free_context, and since
the functions no longer should free the context itself, only
allocated elements within it, the previous naming was slightly
misleading.

This is different from how it is handled in codecs/demuxers/muxers
though (where the close function isn't called if the open function
failed), but since the number of depacketizers that have an .init
function is quite limited, this is easy to change.

The main point is that if the init function failed, we shouldn't
try to use that depacketizer at all - this makes sure that the
parse function doesn't need to check for the things that were
initialized in the init function.

This makes it more consistent with depacketizers that don't have any
.free function at all, where the payload context is freed by the
surrounding framework. Always free the context in the surrounding
framework, having the individual depacketizers only free any data
they've specifically allocated themselves.

This is similar to how this works for demuxer/muxers/codecs - a
component shouldn't free the priv_data that the framework has
allocated for it.

Always use the .priv_data_size field instead.

These functions are far from performance critical, so there's no

This makes it clear that the individual parsing functions can't

They share a great deal of common structure; only a few minor
bits in the headers differ.

This also fixes an off-by-one in sending of the last fragment
of large HEVC nals (where it previously sent len+2 bytes, even
if it should have been len+RTP_HEVC_HEADERS_SIZE aka len+3).

This can reduce the amount of boilerplate in simple depacketizers.
Signed-off-by: Martin Storsjö <martin@martin.st>

This avoids implementing a full function just to set this one
field.

This allows getting rid of quite a bit of boilerplate in depacketizers.

The default value (initializing need_parsing to 0, aka
AVSTREAM_PARSE_NONE) is the same as it is initialized to by default
in AVStream.
