After printing this error, the decoder returns an error. This is pretty bad for me, because I think this causes a slight desync. Looking at the code, I guess it simply fails with AAC_AC3_PARSE_ERROR_SYNC internally. This error also happens when seeking with libdvdread or libdvdnav (in which case seeking with libavformat is not involved at all). This means it fails with the same error in both cases. I'm not sure what to make out of it. I uploaded a sample named "dvdsample" using http://upload.ffmpeg.org/upload/, but I'm not really sure where the upload form put it. (Maybe failed?) -- Ticket URL: <https://trac.ffmpeg.org/ticket/1182#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#3751(undetermined:new): Identity Hald CLUT Introduces Color Shift

#3751: Identity Hald CLUT Introduces Color Shift -------------------------------------+------------------------------------- Reporter: aguo | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi! I'm having an issue with applying Hald CLUTs to a dpx image sequence. I am trying to use ffmpeg to convert a sequence of dpx film scans in logarithmic colorspace into two quicktime files: one with h264 encoding and one with avid dnxhd encoding. In investigating the problems I've been encountering I realized that using hald cluts with ffmpeg introduced color shifts that are external to the corrections specified by the LUT. Even applying an identity hald clut to an image changes the image despite the fact that the identity clut is meant to not change the input image at all. Our command line/build is: C:\Users\aguo>ffmpeg -i I:\studio\software\release\HaldCLUT\EA0570_bright\ea0570_bg_20140214_1.1659199.dpx -i I:\studio\software\release\HaldCLUT\Identity_level_8.HCLUT_neutral.tga -filter_complex 'haldclut' I:\studio\artists\aguo\neutralIdentityCLUTtest.jpg ffmpeg version N-63548-g6b041cb Copyright (c) 2000-2014 the FFmpeg developers built on May 28 2014 22:01:42 with gcc 4.8.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-av isynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enab le-iconv --enable-libass --enable-libbluray --enable-libcaca --enable- libfreetyp e --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable- libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable- libope njpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable- libsox r --enable-libspeex --enable-libtheora --enable-libtwolame --enable- libvidstab - -enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable- libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable- libxavs --enable-libxvid --enable-decklink --enable-zlib libavutil 52. 87.100 / 52. 87.100 libavcodec 55. 65.100 / 55. 65.100 libavformat 55. 42.100 / 55. 42.100 libavdevice 55. 13.101 / 55. 13.101 libavfilter 4. 5.100 / 4. 5.100 libswscale 2. 6.100 / 2. 6.100 libswresample 0. 19.100 / 0. 19.100 libpostproc 52. 3.100 / 52. 3.100 The same problem happens when we use a jpg as the input. This should not change the input at all but actually ends up introducing a color shift that makes the image significantly more blue. My guess is that the issue is that ffmpeg is trying to guess/assign a colorspace to the Hald CLUT and the colorspace interpretation of the Hald CLUT is changing the CLUT. As the guy who created CLUTs explains, "A HaldClut is not really an image (its only stored in an image file format for convinience), its a lookup table. A lookuptables function is to input some values, in our case a 3 dimentional value (RGB), and then output some values, again 3 values in our case. It doesnt really care where thouse values come from or what they mean they just does a conversion. Depending on what you put in the table you can make any kind of conversion. its just a numbers to numbers conversion" If that is the case, is there a way to disable ffmpeg from trying to assign the CLUT a colorspace? Or if that isn't the issue, why would applying an identity CLUT through ffmpeg change in the input image? We got the Identity CLUT straight from the developer's website here: http://www.quelsolaar.com/files/index.html Any help would be greatly appreciated.

I've been searching all over the internet for a way to say...decrypt an .wvm file as I have gotten a hold of such a file from an foreign streaming site. I never heard of an .wvm file until just a few days ago and been wondering how to play and decode such a file...but can not. After all that I have searched, I'm still have not found any way to remove the DRM nor found any way to play back such a file. Along my search I discovered this here thread when looking up if FFmpeg can play/decode an widevine .wvm file but there's no support for it at all. Indeed... What captured my eye though is how someone mention that there's an Samsung Patch for FFmpeg that might have support to play/decrypt (I think) a widevine file. It's hard guess and the original source for the Samsung FFmpeg file is gone so there's no way to find out if it's possible or not... However, just a few minutes ago, I may...of found the Samsung FFmpeg source on an random git type site and I have no idea how to use such file or if it works but I found that the FFmpeg has the "widevine.c" file in an libav folder or somesort. Anyways I hope you guys don't mind me posting this but here's the link to file in a zip format that I uploaded on both "Uppit" and "Mega". Uppit: [http://up.ht/TE02hv/] MEGA: [https://mega.co.nz/#!rA8wlCJL!gNzydQvEsWxPDxp- Yaifl_AP53ZNjuFGiL0XDwREZtE/ MEGA - Samsung FFmpeg?] If any of you guys can be kind, please give the file a look and see if it's indeed the so-called Samsung Patch, I hope i'm not wrong haha. If you want an WVM file to test well...the only WVM file is an cartoon I got from that Foreign Streaming Site so here's the link to it: Uppit: [http://up.ht/TxYhCH/ Uppit - .WVM file] MEGA: [https://mega.co.nz/#!PZdB1Z5C!Gt5X1qPEfIJtemwNeRKK0aHax4U3hYF1vOXhKFy17hs/ MEGA - .WVM file] You don't have to download the .wvm file but if you want to, here you go. Sorry if this isn't of help or you don't appreciate these links i'm posting. Still I hope it helps in the playback of Widevine protected media and maybe this can be helpful in providing Widevine support in FFmepg...in the future! =) That is all and your welcome. May it be of help to y'all! -- Ticket URL: <https://trac.ffmpeg.org/ticket/1793#comment:29> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
