ensure URL is not empty
see also f4f54fda - adding -f to curl caused URL to be empty if release
was not found (was to be created) - the GH REST API returns 404 with
a valid body without -f but fails with empty. Since `-o pipefail` is not
used, the curl error was not used because last command of pipeline is jq.
The REST API returned 4xx on unknown object but valid JSON body. As
written originally, valid JSON was assumed (result queried on null).
So revert back the original curl calls where acquiring JSON.
- '|| true' no longer needded
- CFLAGS also doesn't seem to be required
- remove --disable-shared - when possible, linkling dynamic library may
be rather preferred than the contrary
Co not continue if SDK_NONFREE_PATH is set but deltacast
SDK not present there. At this time, this will fail later in
.github/scripts/install-common-deps.sh, anyways. Also the DELTACAST
SDK remains the last non-free SDK so it doesn't make sense to define
SDK_NONFREE_PATH GH variable while not having that SDK.
GPUJPEG commit 06f18868b message:
````
gpujpeg_reader spiff: directory read fix+updates
- FIXED: skipping content the dir entries other than EOD (+ early returns)
- pass the complete length, not -2 (it is misleading)
- length check - increase from 6 (4+2) to 8 - T.84 says ELEN should be at
least 8 (seems that EDATA should be at least 2 bytes)
```
Improves the commint 4682cf65 (2024-08-19) allowing also the capture
filter to be specified both before and after the vcap (if only one
used), eg. `-F flip -t testcard -F mirror`.
Set the bitrate only if >0. Do not set if neither set explicitly nor by
the codec preset - eg. for APV avg_bpp is intentionally set to 0. The
libopenapv uses CQP by default and setting the bitrate explicitly
disables that.
Note that this setting doesn't do anything important - setting the
AVCodecContext::bitrate to 0 does nothing. This change is avoid displaying
"Setting bitrate to 0.0 bps." message.
setparam callback is free to alter the copy, which is then used for the
actual setting.
blacklist_opts is therefore no longer needed - the formerly blacklisted
option can now be erased from the lavc_opts copy directly.
