How to reproduce: ffmpeg -y -i big_buck_bunny_1080p_h264.mov \ -b:v 3000k -vcodec h264 -t 30 -acodec aac -strict experimental -ab 128k \ -vf "movie='sample-128.png' [wm]; [in] [wm] overlay=W-w-10:H-h-10 [out]" \ "outtest.mp4" I was able to reproduce this with: FFmpeg 2.4 FFmpeg 2.4.1 ffmpeg version N-40926-g303fc9b The exact same command works when replacing the PNG file with a JPEG file. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3977> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

This channel will become the channel for true mono 1.0 channel sets. FC will become the channel to be used for all other channel sets.

#2591: Feature Request: Add ability to use Quick Sync to transcode video files -------------------------------------+----------------------------------- Reporter: zjacobs | Owner: Type: enhancement | Status: open Priority: wish | Component: avcodec Version: git-master | Resolution: Keywords: h264 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+----------------------------------- Comment (by Mjb2000): Apologies for posting a question here, but you guys seem pretty smart so you'll probably know the answer straight away. I'm trying to compile a version of ffmpeg with quicksync support for use in a Windows environment. I've used the pre-compiled binary from the drocon11 fork, but unfortunately I need a few other libraries included in the binary (so this is why I figured I need to build this myself?). I'm just a little confused with the exact environment and tools I should be building with. I've tried to follow the various instructions within some of the dependencies but for instance I couldn't even work out if I should be doing this in a "msys" on Windows, or within Linux. If somebody could outline with a bit more detail how I should go about building the drocon11/ffmpeg-qsv project I'd really appreciate it. Particularly if you could mention the OS, tools and any installation guidelines I should follow that would be great. If it helps, the background to this is that I have a low power j1900 cpu running media browser 3 as a media server, but the cpu struggles why real- time transcoding, however the j1900 supports quicksync and I can get some pretty good performance using quicksync. Unfortunately, the way in which media browser uses ffmpeg seems to require some additional libraries which are bit included in the drocon11 build.

#4006(avutil:new): FFmpeg not parsing Center channel in mov as Center.

#4006: FFmpeg not parsing Center channel in mov as Center. --------------------------------+--------------------------------------- Reporter: billys | Type: defect Status: new | Priority: normal Component: avutil | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------+--------------------------------------- I am trying to extract the audio channel assignments from a MOV. The channel assignments where done using Quicktime Pro 7. The file has 6 mono audio streams which make up a 5.1 channel set. I am expecting to see FL, FR, FC, LFE, BL, BR across the streams. The issue is that I am seeing 'mono' instead of FC. I believe this is an issue with avutil, where that it cannot distinguish between a true mono 1.0 channel and a Center channel that is a part of a surround sound channel set. I will attach the file I have used to this post. Please find the full uncut console output below.
