Add --video-stream and [encoding].video_stream so users can choose which
input video stream is probed for preset helper variables.
Use the selected stream for codec, pixel format, frame rate, output
pixel format, and GOP size metadata while leaving preset stream mapping
unchanged.
Validate CLI stream selectors strictly and ignore invalid config values
with a warning so bad configuration falls back to the default v:0
stream.
Document the new option in the README and man page, add verbose dry-run
output, and provide bash completion for common video stream selectors.
Closes #6.

Keep CLI sentinel variables and bash completion options ordered
consistently so related skip-codec settings stay grouped together.
Align the --backup-dir help text spacing with neighboring options for
cleaner terminal output.

Add --ffmpeg-loglevel so users can choose which ffmpeg messages are
shown during encoding instead of always using the built-in default.
Load the same setting from [output].ffmpeg_loglevel when it is
configured and no CLI value was provided.
Document the new option in the README and man page, and add shell
completion for supported ffmpeg log levels.

|
Add --skip-codec-override so users can ignore configured skip codecs for
a single run and use only codecs provided through --skip-codec.
Defer CLI skip-codec parsing until after config loading so the final
skip list can be resolved independently of option order.
Document the new override behavior in the README and man page, and add
shell completion for the new flag.

Add --backup-dir support so successful encodes can copy the original
file to an existing backup directory before replacing it.
Preserve each source file's absolute path below the backup directory and
avoid overwriting existing backups by appending numeric suffixes when
needed.
Document the new CLI and config option, and add directory completion for
the backup path.

Rename the old savings log feature to size report across the CLI,
configuration, documentation, man page, and bash completion. The new
`--size-report` option keeps the existing `-s` shorthand, while
`--saving`, `--saving-file`, and the `[saving]` config section are
replaced by `--size-report`, `--size-report-file`, and `[size_report]`.
Extend reporting beyond successful encodes. The TSV log now gains a
leading `status` column and records encoded files, codec skips,
only-if-larger skips, and failed inputs. Size-report output also prints
per-file feedback for encoded and skipped-larger files, including
human-readable original/new sizes, bytes saved, and saved percentage.
Track batch-level report counters and print an end-of-run summary for
multi-file runs with encoded/skipped/failed counts, total bytes saved,
and the overall weighted saving percentage across successful encodes.
Document the new TSV schema in the README and man page, update examples
and config snippets, and adjust bash completion for the renamed options.
BREAKING CHANGE: `--saving` is now `--size-report`. `--saving-file` is
now `--size-report-file`. `[saving]` in config.toml is now
`[size_report]`. The TSV log gains a leading `status` column and may
contain skipped and failed rows in addition to successful encodes.

Print all *.sh files found in $PRESET_DIR, one per line, with a one-line
description extracted from the first line of each file if it matches a
`# description: …` comment. Presets without such a comment are listed
without a description.
Symlinks pointing to another preset inside $PRESET_DIR are shown as
"<name> - Symlinked to <target>" rather than duplicating the
description. Symlinks pointing outside $PRESET_DIR are followed and
treated as regular preset files.
Column width for preset names is calculated from the longest name in the
directory so descriptions align with minimal padding.
Also extracts the repeated readlink/realpath idiom into a dedicated
resolve_path() helper and adds a doc comment to filesize().
Exits immediately after printing (same pattern as --version/--help).
Honours --quiet/NO_COLOR via the existing msg() and color
infrastructure.

Add --hwaccel [METHOD] / --no-hwaccel flags to control whether -hwaccel
is passed to ffmpeg before the input file. The METHOD argument is
optional and defaults to "auto", letting ffmpeg select the best
available hardware decoder with automatic software fallback.
Hardware acceleration is enabled by default (method: auto). Users on
hosts where hwaccel causes compatibility or stability issues can opt out
with --no-hwaccel or config.toml [encoding] hwaccel = false.
The config key accepts false (disable), true (auto), or a method string
such as "vaapi" or "cuda". CLI flags take precedence as usual.
Bash completion is extended with a hwaccel_methods word list (auto,
cuda, vaapi, dxva2, d3d11va, videotoolbox, qsv) for both the space form
(--hwaccel <TAB>) and the equals form (--hwaccel=<TAB>).
The completion script is also reformatted from 4-space to 2-space
indentation for consistency with transcode.sh itself.

After ffmpeg exits successfully, run ffprobe against the temporary
output file to confirm it is a valid, playable media file before
replacing the original. If the probe fails the temporary file is removed
and the encode is treated as a runtime failure, leaving the original
untouched.
This guards against cases where ffmpeg exits 0 but has written a
truncated or corrupt container (e.g. due to a disk-full condition
mid-write, a codec bug, or a preset producing an unreadable stream).
The check is enabled by default and can be disabled via
--no-verify-output or [encoding] verify_output = false in config.toml
for large batch jobs on trusted encoders where the extra ffprobe
round-trip is undesirable.
The --continue flag is honoured: a failed integrity check counts as a
runtime failure for the purposes of deciding whether to proceed to the
next file.
Docs, man page, bash completion, and README updated accordingly.

The contact address dennis.fink@c3l.lu has been replaced with
me+coding@dennisfink.me across all files where it appeared:
SPDX-FileCopyrightText, AUTHOR constant, --version output,
README footer, LICENSE file, and the man page AUTHOR section.
SPDX licence headers were also added to transcode.sh.1 and
transcode.sh.bash-completion to bring all files into full
REUSE compliance.

Add a structured config file so common defaults can live in one place
instead of being repeated in aliases or shell wrappers. CLI flags keep
precedence, which keeps one-off overrides predictable.
Use tomlq only when a config file is present, and fail early on missing
dependencies or invalid TOML so configuration mistakes do not silently
change encode behavior.
Move the persistent skip-codec list from the legacy skip.conf file to
[skip] codecs in config.toml. Config codecs are merged with --skip-codec
so global defaults and per-run skips can be combined.
Document the new format in the README and man page, update dependency
notes, and extend bash completion for config-file paths and the new
negative boolean flags.
BREAKING CHANGE: skip.conf is no longer read for codec skips. Migrate
its entries to [skip] codecs in config.toml and remove the old file.
BREAKING CHANGE: --encodefile and --encodefile= are replaced by
--encode-file and --encode-file=. Update scripts, aliases, and
completion usage to use the hyphenated option name.
