Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.

Fragmented mp4 file is not played by MSE
19 mai 2020, par DanielI created a fragmented mp4 file with ffmpeg (from h264), and removed the first 6 moof and mdat pairs.



So now it still has the correct order of boxes : ftyp, moov, moof, mdat, moof, mdat, ..., but the first moof packet has the sequenceNumber of 7.



VLC can play it fine, 'Movies & TV' can also play, but the first some seconds are black.



If I drag the file into the browser, it can also play it fine.



It is however not being displayed at all in the browser (Chrome) if I feed it via MSE.



No error messages are printed, and in the media-internals' log it can be seen that the videoplayer starts playing in the first second and suspends it only in the 18th second :

How should I add a transparent watermark.png over my RTMP h264 stream with ffmpeg ?
16 juin 2013, par RoelandPI have a Raspberry Pi with the new camera module hooked up to (in this case) Bambuser. You can see the stream here, it's from a windmill in The Netherlands (camera position will be better within a few weeks).
I succesfully have the stream running, but now I want to add an image (alpha transparent png) on top of the input-stream which is piped to ffmpeg to be streamed to Bambuser.
I currently use the following command (user specific details wiped out) to succesfully stream the input from the Raspberry Camera module (it's great, HD & all, hardware rendering) to Bambuser, following the great tutorial by Slickstreamer :
raspivid -t 999999999 -w 960 -h 540 -fps 25 -b 500000 -o - | ffmpeg -i - -vcodec copy -an -metadata title="STREAM NAME" -f flv rtmp://USER_X.fme.bambuser.com/b-fme/USER_STREAM_KEY_XI followed the docs about ffmpeg and it seems to me I should use the '-vf'-command to apply the 'movies :' filter, like so :
raspivid -t 999999999 -w 960 -h 540 -fps 25 -b 500000 -o - | ffmpeg -i - -vf "movie='/home/USER/watermark.png' [logo]; [in][logo] overlay=main_w-overlay_w-10:10 [out]" -vcodec copy -an -metadata title="STREAM NAME" -f flv rtmp://USER_X.fme.bambuser.com/b-fme/USER_STREAM_KEY_Xand various other -vf commands, like '-vf vflip' or '-vf mandelbrot'. But it doesn't seem to work, as the stream just shows the direct input from the Raspberry Camera.
This is the output when started with the following -vf command :
raspivid -t 999999999 -w 960 -h 540 -fps 25 -b 500000 -o - | ffmpeg -i - -vcodec copy -vf 'movie=0:png:/home/USER/watermark.png [watermark];[in] [watermark]overlay=0:0:1[out]' -an -metadata title="STREAM NAME" -f flv rtmp://USER_X.fme.bambuser.com/b-fme/USER_STREAM_KEY_Xffmpeg version N-54036-g6c4516d Copyright (c) 2000-2013 the FFmpeg developers built on Jun 15 2013 XX:XX with gcc 4.6 (Debian 4.6.3-14+rpi1) configuration : libavutil 52. 35.101 / 52. 35.101 libavcodec 55. 16.100 / 55. 16.100 libavformat 55. 8.102 / 55. 8.102 libavdevice 55. 2.100 / 55. 2.100 libavfilter 3. 77.101 / 3. 77.101 libswscale 2. 3.100 / 2. 3.100 libswresample 0. 17.102 / 0. 17.102 [h264 @ 0x1917cc0] max_analyze_duration 5000000 reached at 5000000 microseconds Input #0, h264, from 'pipe :' : Duration : N/A, bitrate : N/A Stream #0:0 : Video : h264 (High), yuv420p, 960x540, 25 fps, 25 tbr, 1200k tbn, 50 tbc Output #0, flv, to 'rtmp ://USER_X.fme.bambuser.com/b-fme/USER_STREAM_KEY_X' : Metadata : title : STREAM NAME encoder : Lavf55.8.102 Stream #0:0 : Video : h264 ([7][0][0][0] / 0x0007), yuv420p, 960x540, q=2-31, 25 fps, 1k tbn, 1200k tbc Stream mapping : Stream #0:0 -> #0:0 (copy) frame= 2344 fps= 27 q=-1.0 size= 4827kB time=00:01:33.72 bitrate= 421.9kbits/sAs mentioned above, other -vf filters also don't seem to apply on the output stream on Bambuser, I think I fundamentally do something wrong here.
- Should I map the Raspivid-stream and map the image 'watermark.png' on top of that ? Would that be the solution ? Anyone experience with this ?
Thank you very much for your thoughts in advance.

Package is installed inside docker but actual command provide exception
1er juin 2022, par user1765862I'm trying to use ffmpeg core package inside .net 6 dockerized project. I install ffmpeg core inside Dockerfile, reference actual package FFMpegCore inside solution but when I try to apply any of the commands from the ffmpeg core lib I'm getting error




An error occurred trying to start process './ffmpeg' with working
directory '/var/task'. No such file or directory




Docker build is done with no error.


Dockerfile


FROM public.ecr.aws/lambda/dotnet:6 AS base
....
RUN apt-get install -y ffmpeg
....
FROM base AS final
WORKDIR /var/task
COPY --from=publish /app/publish .


As per ffmpeg core docs in order to use ffmpeg I need to set its binary folder, so I add ffmpeg.config.json


{
 "BinaryFolder": "/var/task",
 "TemporaryFilesFolder": "/tmp"
}


Actual error is being thrown when I try to execute following command




An error occurred trying to start process './ffmpeg' with working
directory '/var/task'. No such file or directory




This is the place where error gets triggered


using FFMpegCore;
 ...
 public class MyController : ControllerBase
 {
 public async Task<string> Get()
 { 
 await FFMpegArguments
 .FromPipeInput(new StreamPipeSource(myfile))
 .OutputToPipe(new StreamPipeSink(outputStream), options => options
 .WithVideoCodec("vp9")
 .ForceFormat("webm"))
 .ProcessAsynchronously();
 ...
 } 
 }
</string>

Update :
After changing
BinaryFolderlocation to/usr/binI'm getting following error

An error occurred trying to start process '/usr/bin/ffmpeg' with working directory '/var/task'. No such file or directory
