![]() #Mplayer dvbt software#Many PC based software packages are able to capture these streams via a digital turner card into TS files. This system transmits video, audio and other data in MPEG-2 transport streams (TS streams). Mplayer output.ac3 -channels 6 -srate 48000 -af hrtfĭigital Video Broadcasting - Terrestrial (DVB-T) is the broadcasting standard used in Australia (and other parts of the world, mainly Europe) for high definition digital television. Or using the audio filter, Head-Related Transfer Function (HRFT) for 6 channel playback on headphones: Playback of 6 channel audio can be via the mplayer command on compatible systems: Mplayer input.VOB -ss 30 -endpos 140 -aid 129 -dumpaudio -dumpfile output.ac3įfmpeg -i input.VOB -ss 30 -t 170 -vn -acodec copy -map 0.8:0.0 output.ac3 Mencoder input.VOB -ss 30 -endpos 140 -aid 129 -oac copy -of rawaudio -ovc frameno -o output.ac3 ![]() #Mplayer dvbt full#You can also extract the full Digital Dolby AC3 stream for playback on a system with 5.1 compatibility with mencoder or mplayer: You can also use the FFmpeg command, mapping the correct audio stream as above via the -map option ( mencoder and FFmpeg handle stream options differently):įfmpeg -i input.VOB -ss 30 -t 170 -vn -acodec pcm_s16le -map 0.8:0.0 -ar 44100 -ac 2 output.wav Mplayer input.VOB -ss 30 -endpos 140 -aid 129 -ao pcm:file=output.wav -srate 44100 -channels 2 -vc dummy -vo null In order to extract a PCM/WAV stereo stream suitable for an audio CD (signed 16 bit little endian at 44,100 Hz), use mplayer with audio output to PCM and no video: In this case ID 129 (or second audio stream). In most cases, VOB files contain multiple AC3 streams, hence the need to select the desired output audio via the -aid option.

I commented out first troublesome HDTV stream, and run mplayer with:Īnd used h and k keys to change channels.One common task is to extract audio from DVD and AVI files.
