Re: [PD-announce] PiDiP 0.8.2 [ EARLY STREAMING ]

hi, again,

i'm also posting the ffserver configuration file i've used for testing with Windows Media Player, it might help.

cheers,

hi,

i've released a new version of PiDiP that includes the new pdp_ffmpeg~ object that lets you stream video and audio to an ffmpeg server.

well, in fact, i do not recommend to stream the audio using this object because PDP is somewhat asynchronous and you cannot guarantee the audio will be streamed steadily.

so, better stick to the former solution and use mp3cast~ to stream audio.

0.8.2 added pdp_ffmpeg~ : stream to a ffmpeg server with possibly several formats ( mpeg, asf, ... ) NOTE : although there is an experimental audio streaming possibility, there are BIG synchronization issues and it's recommended to use mp3cast~ for audio streaming. added a ratio action in pdp_ascii added a planes number action in pdp_quark and pdp_nervous ( plays on speed of switching ) fixed index bug in pdp_ctrack, pdp_cmap

enjoy !!

PS : the installation of PiDiP is now getting rather tricky, you need : imlib2 aalib ffmeg : the sources

# You must use 'ffmpeg' to send a live feed to ffserver. In this # example, you can type: # # ffmpeg http://localhost:8090/feed1.ffm

# ffserver can also do time shifting. It means that it can stream any # previously recorded live stream.

# Number of audio channels : 1 = mono, 2 = stereo #AudioChannels 1
