#5083: Conversion from yuv410p to rgb24 looks wrong ---------------------------------+-------------------------------------- Reporter: khali | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+-------------------------------------- Summary of the bug: When generating still pictures from a yuv410p video stream in PNG or BMP format, the output looks incorrect. The same still pictures written as TIFF or JPEG pictures look right. Given that TIFF and JPEG store the data in YUV color space while PNG and BMP use the RGB color space, this makes me suspect that the conversion from yuv410p to rgb24 is broken. How to reproduce: {{{ % ffmpeg -f lavfi -i "color=color=white:size=16x16" -frames:v 1 -vf "format=yuv410p,drawbox=color=red:x=4:y=4:w=8:h=8" -f image2 410p.png ffmpeg version N-77180-g45938f0 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.8 (SUSE Linux) configuration: --prefix=/opt/ffmpeg --enable-shared --enable-libmp3lame --enable-libxvid --enable-postproc --enable-gpl --enable-x11grab --enable- avfilter --enable-version3 --enable-libx264 --enable-pthreads --enable- libvorbis --enable-libtheora --enable-fontconfig --cpu=corei7 --enable- libfaac --enable-nonfree libavutil 55. 10.100 / 55. 10.100 libavcodec 57. 17.100 / 57. 17.100 libavformat 57. 19.100 / 57. 19.100 libavdevice 57. 0.100 / 57. 0.100 libavfilter 6. 20.100 / 6. 20.100 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.101 / 2. 0.101 libpostproc 54. 0.100 / 54. 0.100 Input #0, lavfi, from 'color=color=white:size=16x16': Duration: N/A, start: 0.000000, bitrate: N/A Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 16x16 [SAR 1:1 DAR 1:1], 25 tbr, 25 tbn, 25 tbc Output #0, image2, to '410p.png': Metadata: encoder : Lavf57.19.100 Stream #0:0: Video: png, rgb24, 16x16 [SAR 1:1 DAR 1:1], q=2-31, 200 kb/s, 25 fps, 25 tbn, 25 tbc Metadata: encoder : Lavc57.17.100 png Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> png (native)) Press [q] to stop, [?] for help [swscaler @ 0x1b9f4c0] Warning: data is not aligned!

While the generated pattern is fully symmetric, the output image is not. Same problem with 410p.bmp as the output. However both 410p.jpg and 410p.tiff look right. Also note that format=yuv420p and format=yuv411p both work properly. So this is not a generic problem with the YUV to RGB color space conversion, rather this seems to be specifically related to yuv410p. Converting from yuv410p to yuv420p seems to also be broken, but differently. See how {{{ % ffmpeg -f lavfi -i "color=color=white:size=16x16" -frames:v 1 -vf "format=yuv410p,drawbox=color=red:x=4:y=4:w=8:h=8,format=yuv420p" -f image2 410p_to_420p.tiff }}} manages to create green pixels from a picture that originally only had white and red. -- Ticket URL: <https://trac.ffmpeg.org/ticket/5083> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

These files are common in some Electronic Arts games, like Harry Potter and the Chamber of Secrets and Brother Bear. The format is similar to adpcm_ea_r1, but the file is always mono, there is no channels header. ADPCM history is always initialized to [0, 0]. File size is always a multiple of 15, there is no raw sample mode (0xEE). Sample rate is 22050Hz by default. Files can be encoded into this format using sx.exe: {{{ > sx -raw -eaxa_blk sample.wav -=sample.XA }} I attached a test case, a XA file and the corresponding decoded raw file. This is decoder code in C# (I release it under CC0): {{{ using System; using System.IO; using System.Text; namespace KoopsAudioDecoder { class Program { static int coeff1, coeff2, shift, adpcmHistory1 = 0, adpcmHistory2 = 0; static readonly int[] EA_XA_TABLE = new int[] { 0, 0, 240, 0, 460, -208, 392, -220, }; static void DecodeSingleFrame(BinaryReader stream, BinaryWriter outbuf) { int frameInfo = stream.ReadByte(); coeff1 = EA_XA_TABLE[((frameInfo >> 4) & 15) << 1]; coeff2 = EA_XA_TABLE[(((frameInfo >> 4) & 15) << 1) + 1]; shift = (frameInfo & 15) + 8; for (int i = 0; i < 14; i++) { int sample_byte = stream.ReadByte(); int[] nibbles = { sample_byte >> 4, sample_byte & 15 }; foreach (int nibble in nibbles) { int sample = GetSample(nibble); outbuf.Write(Clamp16(sample)); } } } private static int GetSample(int nibble) { int sample = (nibble << 28 >> shift) + (coeff1 * adpcmHistory1) + (coeff2 * adpcmHistory2) >> 8; adpcmHistory2 = adpcmHistory1; adpcmHistory1 = sample; return sample; } static private short Clamp16(int sample) { if (sample > 32767) { return 32767; } else if (sample < -32768) { return -32768; } else { return (short) sample; } } static int Main(string[] args) { if (args.Length != 1) { Console.WriteLine("This program takes only one argument, input file"); return 1; } string inputFileName = args[0], outputFileName = Path.ChangeExtension(inputFileName, "raw"); Stream inputFile = File.OpenRead(inputFileName), outputFile = File.OpenWrite(outputFileName); BinaryReader inputFileReader = new BinaryReader(inputFile); BinaryWriter outputFileWriter = new BinaryWriter(outputFile); while (inputFile.Length - inputFile.Position >= 15) { DecodeSingleFrame(inputFileReader, outputFileWriter); } if (inputFile.Length - inputFile.Position > 0) { Console.WriteLine("File has {0} spare bytes.", inputFile.Length - inputFile.Position); } return 0; } } } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/6690> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
