This is now done. New bnhf/ah4c:latest incorporates all of the WebUI and Closed Captions work done by @mackid1993. Congratulations to him for an impressive update to ah4c!
Please consider the :appletv tag now deprecated, with :latest now a unified project. Be sure to use the latest Docker Compose going forward:

- PYATV=${PYATV:-false} # Set to TRUE to run docker-start-pyatv.sh at container start for Apple TV tuners via pyatv, instead of the default docker-start.sh used for adb-based tuners. Case-insensitive; anything else runs the default.
- CHANNELSIP=${CHANNELSIP} # Hostname or IP address of the Channels DVR server itself
- ALERT_SMTP_SERVER=${ALERT_SMTP_SERVER} # The domainname:port of the SMTP server you'll be using like smtp.gmail.com:587. This is for sending ah4c alerts if tuning fails.
- ALERT_AUTH_SERVER=${ALERT_AUTH_SERVER} # The auth server for the e-mail you'll be using like smtp.gmail.com
- ALERT_EMAIL_FROM=${ALERT_EMAIL_FROM} # The e-mail address you'd like your ah4c failure alert e-mails to show as being from.
- ALERT_EMAIL_PASS=${ALERT_EMAIL_PASS} # Gmail and Yahoo both support the creation of app-specific e-mail passwords, and this is the way to go! It's NOT recommended to use your everyday e-mail password.
- ALERT_EMAIL_TO=${ALERT_EMAIL_TO} # The e-mail address you'd like your alert e-mails sent to.
- ALERT_WEBHOOK_URL=${ALERT_WEBHOOK_URL} # URL to GET when an alert fires (same failures that trigger the e-mail); put $reason in the URL and it's replaced with the URL-encoded message. Blank disables it.
- LIVETV_ATTEMPTS=${LIVETV_ATTEMPTS} # For FireTV Live Guide tuning only, set maximum number of attempts at finding the desired channel
- CREATE_M3US=${CREATE_M3US:-false} # Set to true to create device-specific M3Us for use with Amazon Prime Premium channels -- requires a FireTV device
- UPDATE_SCRIPTS=${UPDATE_SCRIPTS:-true} # Set to true if you'd like the sample scripts and STREAMER_APP scripts updated whether they exist or not
- UPDATE_M3US=${UPDATE_M3US:-true} # Set to true if you'd like the sample m3us updated whether they exist or not
- TZ=${TZ} # Your local timezone in Linux "tz" format
- SPEED_MODE=${SPEED_MODE:-false} # Set to false if you'd like the target streaming app to be closed after each tuning cycle (limited script support).
- KEEP_WATCHING=${KEEP_WATCHING} # In supported scripts, set the delay before resending a tuning deeplink to prevent "Are you still watching?" type messages. Examples: Use 4h for 4 hours or 240m for 240 minutes.
- AUTOCROP_CHANNELS=${AUTOCROP_CHANNELS} # Space separated list of channels (by number) with black borders on 4 sides to autocrop while maintaining aspect ratio. Requires LinkPi Encoder!
- LINKPI_HOSTNAME=${LINKPI_HOSTNAME} # Hostname or IP of the LinkPi Encoder's web API. Required for AUTOCROP_CHANNELS.
- LINKPI_USERNAME=${LINKPI_USERNAME} # Username for the LinkPi Encoder's web API. Required for AUTOCROP_CHANNELS.
- LINKPI_PASSWORD=${LINKPI_PASSWORD} # Password for the LinkPi Encoder's web API. Required for AUTOCROP_CHANNELS; not currently read by the bundled scripts, which log in with the LinkPi default password instead.
- USER_SCRIPT=${USER_SCRIPT} # Path to a custom script to run alongside ah4c at container startup. Blank runs nothing extra.
- NULL_FRAME_INSERTION=${NULL_FRAME_INSERTION:-false} # Set to TRUE to fill encoder stalls with MPEG-TS NULL packets (PID 0x1FFF) so the DVR never sees a zero-byte gap mid-recording. Case-insensitive (true/True/TRUE all work); anything else, including 1/yes, leaves the feature off.
- PLAYBACK_DETECTION=${PLAYBACK_DETECTION:-false} # Set to TRUE to hold the stream until the device reports media audio playing and the picture is actually moving, then start on a keyframe, so a recording begins on the program rather than on the app's loading screen. Requires adb access to the tuner; network tuners only. Case-insensitive (true/True/TRUE all work); anything else, including 1/yes, leaves the feature off.
- PLAYBACK_DELAY=${PLAYBACK_DELAY} # Set to a whole number of seconds to skip the start of each tune, so a recording begins on the program rather than on the app's loading screen. Piped through the bundled ffmpeg with -ss and stream copy; no re-encoding, and the skip starts on the next keyframe so it can run slightly past the configured value. The value is the total tune time, scripts included. Supported range is 2 to 30, since the DVR allows a tune about 30 seconds; values outside the range are clamped and logged. Ignored when PLAYBACK_DETECTION is TRUE; network tuners only. 0 or unset leaves the feature off.
- PLAYBACK_STATIC_TIMEOUT=${PLAYBACK_STATIC_TIMEOUT} # Only used with PLAYBACK_DETECTION=TRUE. How many seconds the box may keep the exact player and media session it already had before the check stops watching adb and gates on motion alone. The default is 2, which suits Ospreys; apps that hold one player across channel changes, like the DirecTV app, need more. 0 or unset uses the default.
- HEARTBEAT_INTERVAL=${HEARTBEAT_INTERVAL:-0} # In supported scripts (currently osprey), seconds between keepalive keyevents sent during playback to stop the app's UI inactivity timer from resetting the stream. Set to 0 to disable.
- NVIDIA_VISIBLE_DEVICES=${NVIDIA_VISIBLE_DEVICES} # Closed captions only. Set to all alongside DOCKER_RUNTIME=nvidia to expose an NVIDIA GPU. Empty means no GPU and is the default
- NVIDIA_DRIVER_CAPABILITIES=${NVIDIA_DRIVER_CAPABILITIES} # Closed captions only. Set to compute,utility when using an NVIDIA GPU, so the driver the CUDA engine build needs is passed in
volumes:
- ${HOST_DIR}/ah4c/scripts:/opt/scripts # pre/stop/bmitune.sh scripts will be stored in this bound host directory under streamer/app
- ${HOST_DIR}/ah4c/m3u:/opt/m3u # m3u files will be stored here and hosted at http://<hostname or ip>:7654/m3u for use in Channels DVR - Custom Channels settings
- ${HOST_DIR}/ah4c/adb:/root/.android # Persistent data directory for adb keys
- ${HOST_DIR}/ah4c/captions:/opt/captions # Closed caption settings, and the speech model, engine and any GPU driver downloaded from the Closed Captions page. Stays empty unless you turn captions on
