| * This is a proof-of-concept for using ffmpeg as a HTTP video stream proxy | |
| * that can reduce ad volume. | |
| * | |
| * It only works on streams containing SCTE35 data packets. | |
| * You can check a stream using: | |
| * | |
| * ffmpeg -hide_banner -i <SOURCE_URL> 2>&1 | grep scte_35 | |
| * | |
| * Start the demo: |
Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:
| # filter by request host header | |
| varnishlog -q 'ReqHeader ~ "Host: example.com"' | |
| # filter by request url | |
| varnishlog -q 'ReqURL ~ "^/some/path/"' | |
| # filter by client ip (behind reverse proxy) | |
| varnishlog -q 'ReqHeader ~ "X-Real-IP: .*123.123.123.123"' | |
| # filter by request host header and show request url and referrer header |
| ffprobe -of compact -select_streams v -show_packets [VIDEO_FILE OR STREAM_URL] | grep K$ | awk 'BEGIN{FS="|";last=-1}{split($5,a,"="); if(last != -1) {print "Keframe pos: " a[2] ", Interval: " a[2]-last " seconds"} else {print "Keyframe: " a[2]}; last=a[2]}' |
