Hi, We have a distributed system for delivering and displaying video in which the encoding is done on one node and the decoding is done on another. The video data consists of two separate streams - encoded elementary stream MPEG-2, and MJPEG, both of which are on a proprietary transport. We observe the same problem on both streams. The system is fielded and has been in operation for several years on various 32-bit OS (CentOS and Fedora). We are working on introducing a mixed version consisting of 32-bit and 64-bit platforms. Our current initial test case consists of a decoding machine running a 32-bit version of RHEL 5.3 and an encoding machine running a 64-bit version of RHEL 5.3. We've built the FFMPEG libraries that are on the 64-bit machine using the same source that was used to build the libraries on the 32-bit machine. We're having trouble, apparently, in decoding, as the decoder doesn't return a completed frame (the "got picture" flag is always 0 on return from avcode_dec ode_video). The MPEG-2 header data appears to be correct. We've spent some time debugging this on our side and all looks good there. While we may still find this problem is due to something in our applications, we would like to rule out a codec issue. We are using FFMPEG 0.4.9. What has been the experience with a mix of OS? Can it be done successfully and will it work with our current configuration - for example, is a different version of FFMPEG required for 64/32-bit compatibility?
