[AG-TECH] VPC Screen h261AS converting.

[Andrew Rowley]

Hi,

I am in the process of writing software that will allow conversion of H261AS streams and other AG streams to other formats.  H261AS is a simple modification of the H261 format that allows Any or Arbitrary Size i.e. it is not restricted to 352x288 video.  The best documentation on the format is to look in the codecs e.g. the vic source code.  There is no ffmpeg support for this and h261 support in ffmpeg itself is limited in that it doesn't support the RTP packetization or depacketization of h261.

If you are willing to wait, the ViCoVRE project (http://www.rcs.manchester.ac.uk/research/ViCoVRE) should be complete by March next year, and will support both conversions to and from other common media formats such as avi.  

Andrew :)

I'm trying to find more information out about the h261as codec.

I'm trying to work it so that i can convert a h261as stream recorded in AGVCR and convert in to another format eg. avi.

I can't seem to locate much information on the codec if there is ffmpeg support for etc..

Anyone able to point in the right direction.
