MXF XAVC UHD video stream modified while using the -copy option
by Ronan Ricou 09 Feb '18

09 Feb '18

Hello, I'm trying to remux a MXF XAVC file with the exact same video but only 2 out of the 4 audio tracks. For that I use this command: ffmpeg -i INPUT_FILE -c copy -map 0:v -map 0:a:0 -map 0:a:1 OUTPUT_FILE The thing is, some video data are lost during the remux as my file is smaller than it should be. If I check with MediaInfo, the video stream bit rate, bits/(pixel*frame) value and stream size are smaller. Here is the output of the original file: Video ID : 2 Format : AVC Format/Info : Advanced Video Codec Format profile : High 4:2:2 Intra(a)L5.1<mailto:Intra@L5.1> Format settings, CABAC : No Format settings, GOP : N=1 Format settings, wrapping mode : Frame Codec ID : 0D01030102106001-0401020201323001 Duration : 4 min 30 s Bit rate : 506 Mb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate : 50.000 FPS Standard : Component Color space : YUV Chroma subsampling : 4:2:2 Bit depth : 10 bits Scan type : Progressive Bits/(Pixel*Frame) : 1.219 Stream size : 15.9 GiB (99%) Color range : Limited Color primaries : BT.2020 Transfer characteristics : HLG Matrix coefficients : BT.2020 non-constant And of the remuxed file: Video ID : 2 Format : AVC Format/Info : Advanced Video Codec Format profile : High 4:2:2 Intra(a)L5.1<mailto:Intra@L5.1> Format settings, CABAC : No Format settings, GOP : N=1 Format settings, wrapping mode : Frame Codec ID : 0D01030102106001-0401020201323001 Duration : 4 min 30 s Bit rate : 500 Mb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate : 50.000 FPS Standard : Component Color space : YUV Chroma subsampling : 4:2:2 Bit depth : 10 bits Scan type : Progressive Bits/(Pixel*Frame) : 1.207 Stream size : 15.7 GiB (100%) Color range : Limited Color primaries : BT.2020 Transfer characteristics : HLG Matrix coefficients : BT.2020 non-constant Using current release 3.4.1 and latest nightly (N-89956-gcaa4bd7a9f) does the exact same thing. Any idea what's happening and how I can prevent this loss? Many thanks in advance for your help, Ronan

./configure --enable-libvmaf fails to validate vmaf version
by Chris Davis 09 Feb '18

09 Feb '18

All, I have been having difficulty getting libvmaf enabled. I have been getting null results out of older version so I am attempting to rebuild from the latest versions from git. As far as I can tell. pkg-config is recognizing the vmaf package, it is just not validating the version number for libvmaf. Is anyone else seeing this issue? I have tried this both on Mac OS and Windows/MinGW from the latest versions on git. ./configure --enable-libvmaf libvmaf is version3 and --enable-version3 is not specified. If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user(a)ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem. Thank you, Chris Davis

ADPCM block size for XAudio
by Martin Wahnschaffe 09 Feb '18

09 Feb '18

Dear ffmpeg team & users, I'm using the MonoGame framework for development. It uses ffmpeg to ADPCM encode wave files. Playback is done using xaudio. Problem is that ffmpeg always uses a blocksize auf 1024. xaudio only supports block sizes of up to 512. It would be good to make the blocksize configurable to make it compatible. Someone else from the MonoGame community already created an issue for this: https://trac.ffmpeg.org/ticket/6585 Do you think someone will build a fix for this in the near future? Any suggestions for a workarround? Best, Martin

Hi, I want to sequentially parse a set of input videos and output all their keyframes in monotonic unbroken order... so videos a,b,c,d with 10 frames each should produce 0-50.jpg If thye videos where concatable and the concat process lossless I could do ffmpeg -f concat -i vids.txt concat.vid and then ffmpeg vsync -skip_frame nokey -i concat.vid %06d.jpg But they arent, and it isnt... tips?

video slows down in the middle
by Henry Lau 08 Feb '18

08 Feb '18

Hello, I tried to convert a Webm file to MP4. The output MP4 file is fine, plays normally at the start. But for some reason, in the middle it goes into "slow-motion". It then speeds back up to normal speed at the end. The screenshot below is when I view the output MP4 in QuickTime. At the bottom, you can see a "frame bar" (not sure what it's officially called). The middle part is the part where it slows down. [image: Inline image 1] Command I used to convert: ./ffmpeg -i inputWebm out.mp4 The input video is here <https://drive.google.com/file/d/13zvEciv1Rq6aI-5LSt-9Fg-p2XC2rMOQ/view?usp=…>. The output is here <https://t.yesware.com/ta/fcc4dc28c3803f84e9fb06bb6730ebb57f2ea738/6c27f7a69…> . Does anyone know why the output video slows down in the middle? Because when I view the input file, the "slow down in middle" issue does not happen. Thanks! Henry

Create a video with a sequence of drawtext filters with different effects
by Gianluca F. 08 Feb '18

08 Feb '18

Hi all, I'm figure out how to add as many text as I want to a video ( an existing video OR a video built from an image or a list of images ); my problem is that I cannot simply concatenate drawtext filter, because I need, for each text, to add some kind of filter ( scrolling from left to right, right to left, top to bottom, fade, etc ... ) and I need to work with the timing of each drawtext as it would start from t=0. What i suppose to do, is to create a sort of transparent initial canvas , split that and , for each of splitted canvas, adding text with drawtext and effect. Finally, I could concatenate all the effects with the video input to get the final video with all texts messages. Do you think is a good approach to my problem? can you help me to create the ffmpeg command? Thanks in advance! Gianluca

Is it possible to add a 'keyw' atom to a MP4
by Jason Player 07 Feb '18

07 Feb '18

Is there anyway to add a keyw¹ atom via ffmpeg I¹ve done it via Atomic Parsley in the past and would like do it via FFMPEG. It¹s the only part of my workflow I haven¹t been able to replicate (subtitles- check, all other metadata fields- check). The funny thing is, ffprobe and ffmpeg will display the keyword metadata on my older files, just not set it. I¹ve tried using metadata options, setting metadata from a text file, tried using user-defined key (which I later found out ffmpeg ignores for MP4s). Is there some way I¹m missing or will I just have to bastardize another metadata field to get it done (like lyrics)? Thanks! -Jason

MXF container tags modified when replacing audio
by Frédéric Busnel-Joncour 07 Feb '18

07 Feb '18

Hi, I use ffmpeg to replace audio streams in MXF containers, with -c:v option to leave video stream unchanged. I thought that all MXF metadata and tags would be unchanged, but that's not the case and everything's is changed in the header. Most of time it's not an issue, but in a particular case, the player can't read properly the file as the "Video Line Map" tag value is not what expected. Is there a way to keep all MXF's header value unchanged ? Best, Fred
