OK, thanks. Disclaimer, I'm not that knowledgeable in DPX, I'm just applying the analysis in documents from the bugreport here: http://www.simplesystems.org/users/bfriesen/dpx/ It seems that this alignment was not known or misunderstood, cf. ffmpeg's encoder. Currently, I'm just looking if the image size is too small for alignment to disable it. But I fear that to decode all dpx correctly, one will have to resort to parsing the encoder metadata info. Also, we skip the alpha in this sequence: we have no pixel format for RGBA when the bits per component are between 9 and 15. -- Christophe _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
