Reverts commit b10b81fefbe529be7db14ca65ec4b4a293782d39.
The nameref approach did not work as intended; reverting to restore
correct behaviour.
chore: update revision date2026-02-25T19:23:52ZDennis Fink2026-02-25T19:23:52Zurn:sha1:71ee4e8b74e8c9eeeb5529ce17f922418f800b38fix(skip): join codec keys before passing to verbose()2026-02-25T19:21:08ZDennis Fink2026-02-25T19:21:08Zurn:sha1:f3efff4ecf5ee68c4c8b00197e7706b3c91b6c9b
Joining into a single string ensures the entire list renders uniformly.
feat(core): add warn() and downgrade --saving-file diagnostic to warning2026-02-25T19:20:48ZDennis Fink2026-02-25T19:18:32Zurn:sha1:c5726497460845f55b74e19d9a40d5f949656499
The --saving-file without --saving condition is non-fatal, so using
error() was misleading. Introduce warn() (yellow output, respects
--quiet) and use it for this diagnostic instead.
feat(core): add batch progress counter to processing output2026-02-25T08:17:57ZDennis Fink2026-02-25T08:17:57Zurn:sha1:c7b0c8790709186811ba44bda04ebcc8c81f8256
encode_one now receives the current index and total file count and
includes them in the "Processing" message (e.g. "Processing [2/7]:
file.mkv"). Both the CLI and encode-file paths pre-collect their file
lists into arrays so the total is known before encoding begins.
Also fix a typo in the encode_one step comment ("preserverse" ->
"preserves") and add a note on the filename variable explaining the
single-extension stripping behaviour for multi-dot filenames.
refactor(core): combine ffprobe calls and simplify pixel format selection2026-02-25T08:17:24ZDennis Fink2026-02-25T08:17:24Zurn:sha1:6061504cdc9216c085ef334726bbf7ed3af4ea3f
Merge the two separate ffprobe invocations for codec and pixel format
into one, halving the per-file probe overhead on large batches. Both
error messages now include the filename for easier diagnosis in batch
runs.
Replace the three-way nested if/elif/else for pixel format selection
with two independent case statements — one for chroma subsampling, one
for bit depth — that compose the output format string from two parts.
This eliminates the repetition across the three subsampling branches
and makes adding a new bit depth or subsampling variant a single-line
change. Also add a verbose fallback warning for exotic formats that
don't match any known subsampling pattern.
refactor(preset): return ffargs via nameref instead of global variable2026-02-25T08:16:23ZDennis Fink2026-02-25T08:16:23Zurn:sha1:b10b81fefbe529be7db14ca65ec4b4a293782d39
load_preset now accepts the name of the caller's array as a second
argument and populates it via a nameref (local -n), replacing the
previous implicit global ffargs. The preset is sourced into a local
ffargs contained within load_preset's scope and copied to the caller
on return.
encode_one declares its own local ffargs=() and passes its name to
load_preset, making the data flow explicit and eliminating the implicit
coupling through the global. The nameref variable is prefixed with an
underscore to avoid accidental aliasing of any same-named local in the
calling scope.
fix(cli): improve output consistency and verbose diagnostics2026-02-25T08:14:53ZDennis Fink2026-02-25T08:14:53Zurn:sha1:48e3265ea845437bce4c4895275470e8a1776073
Replace the full help page on no-args with a short usage hint to stderr,
reserving the full help for explicit -h/--help invocations.
Print the active codec skip list at startup under --verbose so
unexpected skips can be diagnosed without resorting to DEBUG mode.
Include the resolved ffmpeg command in dry-run --verbose output, which
is useful for preset authors verifying their ffargs expansion.
Fix the only-if-smaller message to follow the "label: value" convention
used throughout the script.
fix(cli): validate empty option values and improve --saving-file handling2026-02-25T08:13:36ZDennis Fink2026-02-25T08:13:36Zurn:sha1:fa3530b214b63701dda5fd8b53aefeb0f0d776c3
Reject empty values for --encodefile, --saving-file, and --preset in
both the space-separated and equals forms (e.g. --preset= now exits
with a clear error instead of failing later with a confusing message
from the allowlist check).
Track whether --saving-file was set explicitly via SAVING_FILE_EXPLICIT.
Warn when --saving-file is used without --saving, but do not exit, to
allow the combination in aliases and wrapper scripts.
Change the savings log format from space-separated to TSV and write a
header line on first creation, making the file easier to parse both by
eye and programmatically.
