Re: [FFmpeg-user] -b:v option
Sorry I would have to specify a bit more. I want to do this in order to generate a DASH content, one of the profiles sould have the original bitrate, and the other ones fixed values. As an example: ffmpeg -i bunny.mp4 -preset superfast -r 25 -vcodec libx264 -acodec aac -b:a 128k -ac 1 -ar 44100 -map v:0 -b:v:0 source -map v:0 -b:v:1 72 -map v:0 -b:v:2 36 -map 0:a? -f dash -segment_time 5000 C:\ComponentsDeployment\CSD_DATA\VCS\DashStreams\9780081d-c864-4420-9669-8a9feb53f4a6\manifest.mpd. So I would have the fist profile with the original bitrate -b:v:0 source, the second one with 720kbps and the third one with 360kbps. On the other one if not posible, what happens if I set this command? ffmpeg -i bunny.mp4 -preset superfast -r 25 -vcodec libx264 -acodec aac -b:a 128k -ac 1 -ar 44100 -map v:0 -b:v:0 108 -map v:0 -b:v:1 72 -map v:0 -b:v:2 36 -map 0:a? -f dash -segment_time 5000 C:\ComponentsDeployment\CSD_DATA\VCS\DashStreams\9780081d-c864-4420-9669-8a9feb53f4a6\manifest.mpd And bunny.mp4 has a bitrate of 795kbps, which bitrate would be displayed in first profile 1080kbps, does make sense or is posible to increase bitrate??

[FFmpeg-user] FFmpeg vsync option
Dear all, I have a video with two streams, a video stream and a metadata stream, I would like to set the vsync option to set the time stamps according to the video stream. In the documentation ffmpeg of vsync says that: -vsync parameter Video sync method. For compatibility reasons old values can be specified as numbers. Newly added values will have to be specified as strings always. With -map you can select from which stream the timestamps should be taken. You can leave either video or audio unchanged and sync the remaining stream(s) to the unchanged one. I would like to use the -map option to set the timestamps of the rest of the streams according with my video stream, but there is no example provided. How could I achieve this?

[FFmpeg-user] DASH with Thumbnails
Dear All, I am building a DASH VideoPlayer and I need the functionality of viewing thumbnails when scrolling de time bar of the video player. ¿Does FFmpeg support this functionality of adding thumbnails to .mpd? My question is the same as this one retrieved from https://stackoverflow.com/questions/60429301/ffmpeg-dash-with-tiles-of-thumbnail-images: "As of DASH-IF IOP version 4.2, section 6.2.6 defines the notion of image-based tracks in DASH: https://dashif.org/docs/DASH-IF-IOP-v4.3.pdf. This is the ability to have an adaption set made up of mime type images that themselves are a strip of low resolution thumbnails. A player will use these thumbnails when the user hovers their mouse over the video timeline and get a preview of the the frame at that approximate timecode. Theo player website has a page dedicated to this function for playback: https://www.theoplayer.com/blog/in-stream-thumbnail-support-dvr-dash-streams I need to generate a dash stream (not live) using ffmpeg that also contains these thumbnails. I already have an ffmpeg command that will generate the film strip of jpgs which outputs a thumbnail every 5 seconds of input video and joins 5 of these together in a single jpg: ffmpeg -i INPUT -q:v 20 -vf "select=not(mod(n\,125)),scale=480:270,tile=5x1" -vsync vfr output%d.jpg and the mpeg dash itself: ffmpeg -i INPUT -y -map 0 -acodec aac -ac 2 -ar 48000 -s 960x540 -vcodec libx264 -f dash -preset veryfast -b:v:2 1500k -seg_duration 2 output.mpd" But I cannot find a way in ffmpeg to include the thumbnails in the dash mpd file.

Dear all, I am trying to generate dash content with klv metadata, I tried several combinations for that, the last one it seems to have more sense to me is: ffmpeg -i videompeg -r 25 -c:v libx264 -c:a aac -b:a 128k -ac 1 -ar 44100 -b:d 2M -map v:0 -b:v:0 2M -map v:0 -b:v:1 145k -map v:0 -b:v:2 365k -map 0:a? -map 0:d? -b:d 2M -dcodec copy -f dash dash.mpd It seems that klv codec is not supported by ffmpeg that is why I am trying to do '-dcodec copy'. But for dash is not working.

Re: [FFmpeg-user] Video is not reproduced in VLC when streaming in udp with ffmpeg
The problem is not related with multicast. Multicast is for deliver a stream to several devices, and I want test the streaming in my own computer, that is why I am using 127.0.0.1 because it references to my own computer (the localhost ip). It seemed that I needed a buffer in reception. I tried with ffplay -i udp://127.0.0.1:12003?buffer_size=1, it worked.
