VLC/FFMPEG implementation expertise

CC 608/708 closed caption extraction + SCTE-35 (Ad insertion marker) Background: (RTP/RTSP Source MPEG-TS) -> TX-Server (Produce m3u8, *.ts, *.vtt) -> HLS capable Player Specifications: 608/708 : [login to view URL] HLS : [login to view URL] SCTE-35 : [login to view URL] Goal: Create module/codec for VLC or FFMPEG for extracting Closed captions and create SCTE - 35 trigger for ad-insertion marker Test setup (We will provide sample input files) VLC : Source from file : cvlc <sample> vlc://quit --intf=dummy --sout='#transcode:rtp{dst=localhost, port=5005, mux=ts}' TX-Server: vlc -vvv rtp://@:5005 vlc://quit --intf=dummy --sout-transcode-audio-sync --sout='#transcode{vcodec=h264, fps=30, venc=x264{ profile=baseline, keyint=120, b-adapt=1}, scale=1, width=1280, acodec=mp4a, ab=48, channels=2, samplerate=22050}:duplicate{dst=std{mux=ts,dst=-,access=livehttp{seglen=10,delsegs=false, numsegs=5, index=/vol1/www/stream/[login to view URL],index-url=livetv#.ts},mux=ts{use-key-frames},dst=/vol1/www/stream/livetv#.ts}}' FFMPEG: ffmpeg -i rtp://@:5005 -r 30 -g 120 \ -c:a libfaac -ac 2 -ar 48000 -ab 48K \ -s 1920x1080 \ -c:v libx264 -r 24 -tune film -preset slow \ -pix_fmt yuv420p -bsf:v h264_mp4toannexb \ -hls_list_size 5 -hls_time 10 /vol1/www/stream/[login to view URL] Deliverables: • Working code that compiles (including build system) with current git version of VLC or FFMPEG and generate compliant HLS segments. • Documentation - How it works and what is done • Complete source code + docs • Email/Chat support (If significant will be compensated) Note: We will provide sample content.
