Dependencies
| Tool |
Needed |
Why |
ffmpeg |
required |
scenario execution, encode/transcode, and mux packaging |
ffprobe |
required |
criteria probing and stream/metadata inspection |
E2E Verification
This profile is considered e2e-verified when its mapped suites pass in CI.
| Suite |
What it proves |
Toolchain version report |
tests/e2e/run_profile_actions_e2e.sh |
action-level output behavior, guardrails, and subtitle-intent pathways |
tests/e2e/.reports/latest/run_profile_actions_e2e_toolchain_versions.md |
tests/e2e/run_device_conformance_e2e.sh |
conservative device-target conformance for stock targets |
tests/e2e/.reports/latest/run_device_conformance_e2e_toolchain_versions.md |
| Field |
Value |
| Codec |
hevc |
| Bit depth |
any |
| Color space |
bt709 |
| Min resolution |
352x240 |
| Max resolution |
3840x2160 |
Scenario Map
| Scenario |
Command |
CODEC_JUST_RIGHT RES_JUST_RIGHT |
ffmpeg -nostdin -i $vfo_input -c copy -map 0 -movflags faststart -strict -2 $vfo_output |
RES_TOO_HIGH |
transcode_hevc_4k_profile.sh $vfo_input $vfo_output |
ELSE |
transcode_hevc_4k_profile.sh $vfo_input $vfo_output |
Runtime Behavior
- Scenario
CODEC_JUST_RIGHT RES_JUST_RIGHT uses direct ffmpeg command execution.
- Scenario
RES_TOO_HIGH uses action script transcode_hevc_4k_profile.sh.
- Scenario
ELSE uses action script transcode_hevc_4k_profile.sh.
| Aspect |
What this profile expects / does |
| Starting containers |
mkv, mp4, mov, mxf (anything ffmpeg can demux) |
| Required codec envelope |
hevc / any-bit / bt709 |
| Required resolution range |
352x240 to 3840x2160 |
| If criteria do not match |
candidate is routed to another profile or skipped |
| If criteria match |
scenario order is evaluated and first match executes |
| Output intent |
output container and streams are defined directly by the ffmpeg command |
