[FFmpeg-user] metadata from concat list not working
Hi.
I am trying to create a video from my music files, creating audio
visualization with showfreqs and displaying current filename with drawtext.
Here is my command:
ffmpeg -f concat -safe 0 -i files.txt -filter_complex
"[0:a]showfreqs=cmode=separate:colors=cyan|orange,drawtext=text='%{metadata\:title\:blah}':font=verdana:fontsize=56:fontcolor=white:x=(main_w/2-text_w/2):y=20[outv]"
-map [outv] -map 0:a -c:v h264_nvenc -c:a copy -pix_fmt yuv420p -shortest
video.mkv
And this is my files.txt:
file 'Alarm01.wav'
file_packet_metadata title=Alarm01
file 'Alarm02.wav'
file_packet_metadata title=Alarm02
Somehow this is not working for me and I don't understand why. My video
displays text "blah", which tells me that ffmpeg can't find the metadata...
I was also reading this: https://rensa.co/projects/ccrc-weather-station/
and they have done pretty much the same, only with pictures. And it worked
for them. I tried to reproduce what they have done - with pictures - but I
again don't get the metadata drawn...
Any help would be appreciated.
Kind regards.
Goran

Re: [FFmpeg-user] metadata from concat list not working
Hi Nicolas, I am trying to understand what you meant, but unfortunately I don't get it. I am still a beginner with video filters of ffmpeg and what I read in the documentation for stream metadata and packet metadata didn't help me to see what I was confusing. What I would like to understand is why does it work for the weather station (the link in my first email) and why is the same logic accepted here: https://superuser.com/questions/1336844/is-it-possible-to-burn-a-filename-watermark-in-the-corner-of-a-concatenated-imag as an answer. When I try to reproduce what the weather station has or what this second link describes, I don't get the text in the video. The weather station even posted its video and there you can clearly see that the metadata from custom-list.txt is displayed on bottom-left of the video <https://www.youtube.com/watch?v=nq4ZGtLOw6Q>. If it worked for them, why doesn't it work when I try to reproduce it? Best regards.

Re: [FFmpeg-user] metadata from concat list not working
Hi everyone, I apologize for spamming... I just saw that it is in fact working for me when I do it with pictures, I was just using such examples that the text was not visible. Sorry. So, yes, it seems I don't understand what is different when I create video from a bunch of pictures and when I use filter_complex to create video from audio files and try to write text over it... I assume that the "picture way" is then packet and the "audio visualization filter way" is then a stream. So I think my question should be: Can I inject metadata to a stream? Best regards.

Re: [FFmpeg-user] metadata from concat list not working
OK, thanks to everyone who answered. I couldn't figure it out any other way, so I am just sending you my solution in case anyone is interested. Step 1 (use for loop to create videos (mkv) from all audio files - in my case wav, change that to what you need): for %i in (*wav) do ffmpeg -i %i -filter_complex "[0:a]showfreqs=cmode=separate:colors=cyan|orange,drawtext=text='%~ni':font=verdana:fontsize=56:fontcolor=white:x=(main_w/2-text_w/2):y=20[outv]" -map [outv] -map 0:a -c:v h264_nvenc -c:a copy -pix_fmt yuv420p -shortest %~ni.mkv Step 2 (use for loop to create a list of all created videos): for %i in (*mkv) do echo file '%i'>>video.txt Step 3 (concatenate all videos into one): ffmpeg -f concat -safe 0 -i video.txt -c copy finale.mkv If anyone has any more suggestions how to bring this into one step, that would be awesome, if not, this is how to do it if you need/want it.

Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Hi. If you are only changing the container and don't want to transcode the contents, be sure to add -c copy in the ffmpeg line of the example (haven't tested it but it seems fine), so it looks like this: ffmpeg -i %IN% -y -c copy %OUT% Br.

Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Michael, you could use this: %~ni <- this means the filename without the extension, so instead of renaming, just use: ffmpeg -i %1 -y %~n1 or ffmpeg -i %1 -y -c copy %~n1 On Mon, Oct 21, 2019 at 10:28 AM Michael Koch wrote: > > > > > set OUT=%IN:mkv=mp4% > > please note that this renaming will give unexpected results if "mkv" is > also part of the filename, for example > aamkv.mkv will be renamed to > aamp4.mp4 > > If someone knows a solution to this problem, please let us know. > > Michael > ___ > 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 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".

Re: [FFmpeg-user] Can ffmpeg convert these mp4 to that mp4?
mp4 is just a container, we need to know what is inside this container. What video, what audio! Use ffprobe on those files and send us the results.
