Hello, I have some problems to encode a file from a dpx 16bit sequence to ffv1 and create a proper framemd5 checksum. The problem is like this, that the checksum from the file is different to the checksum of the dpx frames. My video has only 1 sec of the same pictures.
First I create the ffv1 like this: ffmpeg -f image2 -framerate 24 -i \\ExaSan\dpx\Testbild_16bit\testbild_%06d.dpx -vcodec ffv1 -level 3 -g 1 -slices 16 -slicecrc 1 -context 1 d:\videos\testbild_16bit.mkv The checksum from the mkv is create as follows ffmpeg -i d:\videos\testbild_16bit.mkv -vsync drop -f framemd5 d:\Videos\\testbild_16bit_mkv_framemd5 The checksum from the Image sequence is create as follows ffmpeg -f image2 -framerate 24 -i \\ExaSan\dpx\Testbild_16bit\testbild_%06d.dpx -vsync drop -f framemd5 d:\Videos\testbild_16bit_dpx_framemd5 The result of the frammd5 is as follows: For the mkv file #format: frame checksums #version: 2 #hash: MD5 #software: Lavf58.62.100 #tb 0: 1/24 #media_type 0: video #codec_id 0: rawvideo #dimensions 0: 2048x1536 #sar 0: 1/1 #stream#, dts, pts, duration, size, hash 0, 0, 0, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 1, 1, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 2, 2, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 3, 3, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 4, 4, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 5, 5, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 6, 6, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 7, 7, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 8, 8, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 9, 9, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 10, 10, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 11, 11, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 12, 12, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 13, 13, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 14, 14, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 15, 15, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 16, 16, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 17, 17, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 18, 18, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 19, 19, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 20, 20, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 21, 21, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 22, 22, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e 0, 23, 23, 1, 18874368, 1433afb7948e09dab21fde3b3d734c7e And for the dpx file: #format: frame checksums #version: 2 #hash: MD5 #software: Lavf58.62.100 #tb 0: 1/24 #media_type 0: video #codec_id 0: rawvideo #dimensions 0: 2048x1536 #sar 0: 0/1 #stream#, dts, pts, duration, size, hash 0, 0, 0, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 1, 1, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 2, 2, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 3, 3, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 4, 4, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 5, 5, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 6, 6, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 7, 7, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 8, 8, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 9, 9, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 10, 10, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 11, 11, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 12, 12, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 13, 13, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 14, 14, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 15, 15, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 16, 16, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 17, 17, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 18, 18, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 19, 19, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 20, 20, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 21, 21, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 22, 22, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 0, 23, 23, 1, 18874368, 5c591bbd7f656cdae0e0495ae34cf830 -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
