[FFmpeg-user] Issue when retrieving stream metadata with ffprobe
Hello All, ffprobe does not seem to be able to retrieve all the metadata entries within a container. I am using ffmpeg version 4.1 for MS Windows (build 20181017). My purpose was to give names to the 2 subtitle streams (mov_text) of my movie. Therefore, I did it like this : ffmpeg -i INPUT.mp4 \ -c copy \ -map 0:v:0 -map 0:a:0 -map 0:s:0 -map 0:s:1 \ -metadata:s:s:0 "title=Short version" \ -metadata:s:s:1 "title=Full version" \ OUTPUT.mp4 Then, I issued the following command to check the result of the previous one : ffprobe -show_streams OUTPUT.mp4 The ffprobe command did NOT retrieve the titles of the subpictures. I tried several other ffprobe options but none of them retrieved the titles. However, I am sure that this metadata is stored somewhere because VLC Software from Videolan do DISPLAY it correctly in its Subtitles menu. How can I retrieve this data using ffprobe ?

Your questions made me check the source in more detail =) I picked a random test video from FFMPEG test cases to run through processing. The audio duration is longer than the video duration.

> I am not sure what you mean? I thought I was doing a simple encoding: > > - One input video only, one output for video. > - One audio input plus a finalized video input for the audio output. Yes, but you have separate (raw) input sources. I think by alignment you are referring to the segment durations varying from each variant to another which could be a simple fix (at least I think?) > Map is used to end up with a video only stream and an audio only stream. by using the variant map for the hls muxer. But then when you play the result, are the video and audio going to be in sync is what I’m wondering, since they come from separate sources, and processed on separate tasks. > I am only including the copied video because I was under the impression > that it was required to properly segment the audio file. The audio stream doesn’t even have to be ts, you could have separate aac files for each segment. If you mean properly wrt synchronization, that’s what I’m wondering, since you have separate audio and video sources, is that even going to make any difference? i.e. if you simply multiplex the input and output, are the video and audio in sync? If so, using that file and variant map would make things a lot simpler. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

I am not sure what you mean? I thought I was doing a simple encoding: - One input video only, one output for video. - One audio input plus a finalized video input for the audio output. Map is used to end up with a video only stream and an audio only stream. I am only including the copied video because I was under the impression that it was required to properly segment the audio file.

Re: [FFmpeg-user] why are my streams not aligned?
The target duration randomly being changed to 7 is weird, but why are you doing this at all? Can’t you just do a simple encoding to a ts file for the video first with the right gop settings then have that be the reference for creating the hls playlist?

Re: [FFmpeg-user] ffmpeg cuvid not transcoding properly
I just noticed this but it some examples it seems you are specifying h264 decoder for an input that (apparently) is mpeg? I’m not sure which is which, but I think cuvid and nvdec differ in the way they map or copy to graphics memory thought maybe that might be the difference between the logs (hw decoder into gpu you probably need to specify format, especially when its input is http, I don’t know if in ffmpeg the protocol takes mime type into account.)

Re: [FFmpeg-user] Piping raw video from ffmpeg
Thanks Carl Eugen, that worked. I will have a look at the pix_fmt option. I now have to find how to pipe correctly to gstreamer, as it does not like what I'm feeding him with. WARNING: erroneous pipeline: could not link fdsrc0 to mpph264enc0, mpph264enc0 can't handle caps video/x-raw, format=(string)nv12, width=(int)1920, height=(int)1080, framerate=(fraction)30/1 Bruno On Mon, Nov 18, 2019 at 12:09 PM Carl Eugen Hoyos wrote: > > > > > Am 15.11.2019 um 18:29 schrieb Verachten Bruno : > > > > So far, I have tried ffmpeg -f v4l2 -pix_fmt nv12 -s 1920x1080 -r 30 > > -i /dev/video0 -c:v rawvideo -f yuv - >/dev/null > > The name of the rawvideo format is not “yuv” (as the console output told you) > but “rawvideo”. > You may also want to use the pix_fmt option. > > Carl Eugen > ___ > ffmpeg-user mailing list > ffmpeg-user@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-user > > To unsubscribe, visit link above, or email > ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe". -- Bruno Verachten ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-user] why are my streams not aligned?
Why are the segments for my stream not aligned? The first command outputs video segment. The second command outputs an audio segment with the previous video output copied in.
