Additionally, what I understand is that the packetisation is of 3 types, main header, tile part header and codestream packets. However, if I understand it correctly, the rtp encoder provides an encoded j2k codestream. To get the codestream packets from this, the codestream will have to be decoded. Any suggestions on how to solve this? It does not make sense to decode a codestream for this purpose. Can the tile part packets be dumped from the encoder itself? -- ------------- Gautam | _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
