Docker postprocessing script

[aTF6i]

OK, yes so it was a combination of trying different folders. (it isn't /app/data/scripts (there is a file that says it is)), case sensitivity, script errors, cancelling early etc

For future use:

The folder to use is /config/scripts/
As stated above, cancelling a recording triggers PostCancel.sh. (You will want this one for testing) (NOTE CASE ON FILE - ALSO CHMOD +X)
Completed recordings trigger PostProcessing.sh (NOTE CASE ON FILE - ALSO CHMOD +X)

Here is my script to process differently based on resolution

Code:

#!/bin/bash RECORDING_PATH="$1" OUTPUT_PATH="$(dirname "$RECORDING_PATH")" LOG() { logLoc=/config/scripts/script.log echo "$(date '+%d-%m-%Y %H:%M:%S') - $1" >> $logLoc } LOG "Post-processing started for file: $RECORDING_PATH" # Get video resolution width WIDTH=$(ffprobe -v error -select_streams v:0 -show_entries stream=width -of csv=p=0 "$RECORDING_PATH" | head -n 1) LOG "Resolution width: $WIDTH" # Define output file path OUTPUT_FILE="$OUTPUT_PATH/$(basename "${RECORDING_PATH%.*}").mkv" LOG "OUTPUT FILE: $OUTPUT_FILE" # Remove commercials comskip "$RECORDING_PATH" # Check resolution width and apply different processing if [[ "$WIDTH" -eq 1920 ]]; then LOG "Processing HD video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset veryfast -crf 26 -c:a copy "$OUTPUT_FILE" elif [[ "$WIDTH" -eq 1280 ]]; then LOG "Processing 720p video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset fast -crf 25 -c:a copy "$OUTPUT_FILE" else LOG "Processing SD video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset medium -crf 24 -c:a copy "$OUTPUT_FILE" fi # Check if transcoding was successful if [[ $? -eq 0 && -f "$OUTPUT_FILE" ]]; then LOG "Transcoding successful, removing original file" rm "$RECORDING_PATH" else LOG "Transcoding failed, keeping original file" fi # Send notification LOG "Recording processed: $(basename "$RECORDING_PATH")"

I have yet to test comskip - Any input appreciated on that
I will monitor transcode times/quality and adjust as needed

Your input is apprecated as always, Martin

updated script if anyone wants it

It seems to be working well

Code:

#!/bin/bash RECORDING_PATH="$1" OUTPUT_PATH="$(dirname "$RECORDING_PATH")" LOG() { logLoc=/config/scripts/script.log echo "$(date '+%d-%m-%Y %H:%M:%S') - $1" echo "$(date '+%d-%m-%Y %H:%M:%S') - $1" >> $logLoc } # Function to convert duration to seconds duration_to_seconds() { local DURATION=$1 local HOURS=$(echo $DURATION | cut -d':' -f1) local MINUTES=$(echo $DURATION | cut -d':' -f2) local SECONDS=$(echo $DURATION | cut -d':' -f3 | cut -d'.' -f1) local MILLISECONDS=$(echo $DURATION | cut -d':' -f3 | cut -d'.' -f2) echo $((10#$HOURS * 3600 + 10#$MINUTES * 60 + 10#$SECONDS)) } # Function to calculate absolute difference abs_diff() { local DIFF=$(( $1 - $2 )) if (( DIFF < 0 )); then DIFF=$(( -DIFF )) fi echo $DIFF } LOG "Post-processing started for file: $RECORDING_PATH" # Get video resolution width WIDTH=$(ffprobe -v error -select_streams v:0 -show_entries stream=width -of csv=p=0 "$RECORDING_PATH" | head -n 1) LOG "Resolution width: $WIDTH" # Define output file path OUTPUT_FILE="$OUTPUT_PATH/$(basename "${RECORDING_PATH%.*}").mkv" LOG "OUTPUT FILE: $OUTPUT_FILE" START_TIME=$(date +%s) # Check resolution width and apply different processing if [[ "$WIDTH" -eq 1920 ]]; then LOG "Processing HD video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset veryfast -crf 26 -c:a copy -sn -y "$OUTPUT_FILE" elif [[ "$WIDTH" -eq 1280 ]]; then LOG "Processing 720p video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset fast -crf 25 -c:a copy -sn -y "$OUTPUT_FILE" else LOG "Processing SD video" ffmpeg -i "$RECORDING_PATH" -c:v libx264 -preset medium -crf 24 -c:a copy -sn -y "$OUTPUT_FILE" fi END_TIME=$(date +%s) # Calculate and log the transcode time TRANSCODE_TIME=$((END_TIME - START_TIME)) LOG "Transcoding time: $TRANSCODE_TIME seconds" # Check if transcoding was successful if [[ -f "$OUTPUT_FILE" ]]; then LOG "Transcoded file present" else LOG "Transcoding - File check failed, keeping original file" exit fi # Verify the duration of the input and output files INPUT_DURATION=$(ffmpeg -i "$RECORDING_PATH" 2>&1 | grep "Duration" | awk '{print $2}' | tr -d ,) OUTPUT_DURATION=$(ffmpeg -i "$OUTPUT_FILE" 2>&1 | grep "Duration" | awk '{print $2}' | tr -d ,) INPUT_SECONDS=$(duration_to_seconds $INPUT_DURATION) OUTPUT_SECONDS=$(duration_to_seconds $OUTPUT_DURATION) TOLERANCE=15 # Allowable difference in seconds DIFF=$(abs_diff $INPUT_SECONDS $OUTPUT_SECONDS) LOG "Input duration (seconds): $INPUT_SECONDS" LOG "Transcode duration (seconds): $OUTPUT_SECONDS" LOG "Duration difference (seconds): $DIFF" if (( DIFF <= TOLERANCE )); then LOG "Transcoding successful, removing original file" rm "$RECORDING_PATH" #Remove commercials LOG "Processing comskip..." comskip --ini=/config/scripts/comskip.ini "$OUTPUT_FILE" # Send notification LOG "Recording processed: $(basename "$RECORDING_PATH")" else LOG "Transcoding - Duration check failed, keeping original file" exit fi
