Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

FFmpeg concatenate video and add watermark
18 avril 2020, par user7356972I have command to overlay two video one on other.



ffmpeg -i input.mp4 -vf "movie= overlay.mov [a]; [1][a]scale2ref[2nd][ref];[2nd][ref]overlay=0:0 [c]" output.mp4 




Now I want to add water watermark and concatenate a new video
append.mov
in above command. I have found a command to add watermark.


ffmpeg -i output.mp4 -i watermark.png -filter_complex "overlay=10:10" outputwatermark.mp4




But I want to merge both the command and also need to concatenate
append.mov
tooutput.mp4
.


Also above overlay two video command takes too long time to process if video size is large. Any suggestion on that(should not affect quality of video) ?



I tried following command to concatenate video.



ffmpeg -i abc.mp4 -i ../input/overlay2.mov append.mp4




The video was not concatenate, below is the output.

FFMPEG restream m3u8 to Youtube keeps returning "Failed to update header with correct duration & filesize" after 1st segment
12 septembre 2020, par user3263433I'm trying to retream a m3u8 live feed toYouTube but I keep running into errors.


When watching the feed in a webplayer it works fine.


The headers of the m3u8 file are as follow :


#EXTM3U
#EXT-X-VERSION:6
#EXT-X-TARGETDURATION:8
#EXT-X-MEDIA-SEQUENCE:127629
#EXT-X-DISCONTINUITY-SEQUENCE:0
#EXT-X-PROGRAM-DATE-TIME:2020-09-12T12:57:13.280Z



Here is the ffmpeg log :


frame= 226 fps= 25 q=29.0 size= 1303kB time=00:00:07.04 bitrate=1516.2kbits/frame= 238 fps=

It seems like it loads 1 .ts file fine but fails after that.


I'm currently using :


ffmpeg -re -i (urlToM3U8) -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/(streamkey)

Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux
15 février 2020, par miguelmorinI need to run a command with a nightly build of FFMPEG to report a bug on the
concat
protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.I call this command to concatenate the files :
ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4
where
files_to_combine
is :file ./short_DSC_0013.MOV
file ./short_DSC_0014.MOV
file ./short_DSC_0015.MOV
file ./short_DSC_0016.MOV
file ./short_DSC_0017.MOV
file ./short_DSC_0018.MOV
file ./short_DSC_0019.MOVI call this command from the directory containing the video files and
files_to_combine
.On Windows with a nightly build, I get the error :
files_to_combine : Invalid data found when processing input
I changed
file ./DSC_0013.MOV
to these options, all with the same error :file 'short_DSC_0013.MOV'
file '.\short_DSC_0013.MOV'
file 'F:\short_DSC_0013.MOV'How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?
Update with log-level 48
I ran the same command with
-v 48
