Could somebody explain why this code fails when FILTER_STRING is not "scale", but just "fifo" or "copy"? https://gist.github.com/1834778 The reason is that AVFrame out from filtergraph has 0x0 dimensions. The point is that pixel format conversion must take place, but i don't understand why avfilter doesn't sort it out automatically. It is surprising because when i open "buffer" video source for avfilter, i point in its params that input is in PIX_FMT_RGBA. Could / should this be "fixed", so auto-coversion took place in such cases? If so, i'd appreciate advices how to patch the libavfilter.
