#5514(avcodec:new): Interlaced HEVC Steam not Decoded Properly

#5514: Interlaced HEVC Steam not Decoded Properly -------------------------------------+------------------------------------- Reporter: jlsantiago0 | Type: defect Status: new | Priority: normal Component: avcodec | Version: git- Keywords: | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: I have a 480i interlaced HEVC elementary stream. The HM reference decoder decodes the stream and generates 720x480 interlaced frames. FFMPEG/FFPLAY decodes the stream and 720x240 progressive frames and FFPLAY plays them at half the frame rate with the first/second field/frames bouncing up and down a line because these are actually 2 different fields of the same frame.

#5748(ffmpeg:new): M3U8 playback broken after seek in Safari OSX/iOS

#5748: M3U8 playback broken after seek in Safari OSX/iOS -------------------------------------+------------------------------------- Reporter: bmurphy1976 | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: Keywords: m3u8 | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- I recently tried upgrading to ffmpeg 3.1 and a number of videos that previously worked without issue in Safari on OSX and iOS are now broken when remuxed into M3U8 format. The specific behavior is that the video starts playing without any issues and if you watch from beginning to end there won't be any problem. However, if at any point you try to seek (sometimes it might take two or three attempts) the video stream will crash. Playback will either stop entirely, or the video stream will crash but audio stream will continue playing.

#6260(ffmpeg:new): NVENC H.264 encoding causes aliasing / stair-stepping colors, worse on interlaced than progressive

#6260: NVENC H.264 encoding causes aliasing / stair-stepping colors, worse on interlaced than progressive -------------------------------------+------------------------------------- Reporter: alexpigment | Type: defect Status: new | Priority: important Component: ffmpeg | Version: Keywords: NVENC, | unspecified aliasing, interlaced, | Blocked By: progressive, chroma | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When encoding to H.264 with the NVENC encoder, I'm seeing a pronounced aliasing or stair-stepping effect that happens on the colors (chroma- only?) during motion. This occurs on progressive encodes, but is worse on interlaced encodes. I have verified this behavior on both an Nvidia 1060 and an Nvidia 750 while using the newest static Win64 build from Zeranoe as well as a build from January. To rule out a problem with the GPU, driver, or NVENC itself, I used Staxrip x264 1.4.0.0 to encode with NVENC H.264 on 2 samples and saw no issues. Therefore, this issue appears to be specific to the FFMPEG implementation of NVENC. FFMPEG x264 does not suffer from this issue either. How to reproduce: % ffmpeg -i interlacedsample.mp4 -c:v h264_nvenc -b:v 20000000 -flags +ilme+ildct interlacedoutput.mp4 View the file in a player that supports deinterlacing (I'm using WMP 12 for consistency). Notice that the colors of the rings have massive stair- stepping around the curves, particularly in the lower right where the red and green intersect. As mentioned above, this also occurs on progressive, albeit to a lesser but still very problematic degree. % ffmpeg -i progressivesample.mp4 -c:v h264_nvenc -b:v 20000000 progressiveoutput.mp4 The same problem occurs here, most notably at hte top of the blue right and at the intersection of the green and red rings at the bottom left. ffmpeg version N-84348-gdb7a05d built on 2017-03-21 -- Ticket URL: <https://trac.ffmpeg.org/ticket/6260> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
