Hi @marcuslindblom ,
It seems you are trying to pipe a MP4 container into FFmpeg. A standard MP4 container has its index at the end of the file (https://msdn.microsoft.com/en-us/library/windows/desktop/ee663601(v=vs.85).aspx#media_containers), so FFmpeg try to seek into the file but fails and errors with pipe:: Invalid data found when processing input.
If you are trying to stream a file over HTTP you can use the http input (http://ffmpeg.org/ffmpeg-protocols.html#http).
if not you can use Fragmented MP4 format which is a variant of MP4 designed to be streamed. or you could extract the raw streams and pipe them into ffmpeg.
from ffmpeg.

commented on May 30, 2024
@GnaphronG Ok, I see. To use the fragmented MP4 format, do I need to convert the file in some other tool first and then stream the file to ffmpeg?
from ffmpeg.
marcuslindblom
commented on May 30, 2024
Also, why does the same MP4 file work like this? #48
from ffmpeg.
GnaphronG
commented on May 30, 2024
@marcuslindblom, could you paste the command line you use to run the container ?
you can use -movflags faststart when you generate the MP4 to set the index at the beginning of the file
from ffmpeg.
marcuslindblom
commented on May 30, 2024
@GnaphronG does -movflags faststar fix the problem with the incoming stream? I tried it but it didn't work. You can see the complete command below.
Im not sure how I can see the exact command. I'm using https://github.com/Microsoft/Docker.DotNet/ to create, start and attach the container. Docker.DotNet takes advantage of the remote docker api but I'm not sure how I can see the command. Do you know how I can debug the remote api?
This is the command, from my c# code:
var createContainerParameters = new Config
{
Image = "911fc62f478e",
ArgsEscaped = false,
AttachStderr = false,
AttachStdin = true,
AttachStdout = true,
Cmd = new string[] {
"-i", "pipe:",
"-movflags", "+faststart",
"-c", "copy",
"-loglevel", "debug",
"-f", "mjpeg",
"-c:v", "mjpeg",
"-q:v", "10",
"-frames:v", "1",
"pipe:"
},
OpenStdin = true,
StdinOnce = true
};from ffmpeg.

If I use -movflags faststart and generates a new mp4 I end up with this log even though I use -loglevel debug

According to https://github.com/Microsoft/Docker.DotNet#known-issues--todo, "HTTP Hijacking is not implemented yet, therefore "Attach to Container" operation does not exist in the library (expecting pull requests!) A workaround might be using WebSockets (/attach/ws)."
So it seems piping to a container using the .Net implementation of the Remote API is not yet possible .
from ffmpeg.
marcuslindblom
commented on May 30, 2024
Hm, maybe you are right @GnaphronG. The thing is that I use another container (ImageMagick), the same .NET api and stream image files of different types and it works fine. I'm new to the docker scene so I'm not sure but this seems like "Attach to container" operation exists and the documentation is not updated?
stream = await client.Containers.AttachContainerAsync(createContainerResponse.ID, isTTY.GetValueOrDefault(), containerAttachParameters, token);Maybe ImageMagick and ffmpeg handles stream differently?
I used the the http api before and is seems to work with all different types of video files?

@marcuslindblom could you share the mp4 file that is causing problem ?
from ffmpeg.

commented on May 30, 2024
@GnaphronG Sure, here is one of the files I have problem with. Actually I haven't got any luck streaming any file at all. https://cl.ly/lUJf

Thank you @marcuslindblom, with this file i was able to reproduce your issue using: cat A001_C009.mp4 | docker run -i jrottenberg/ffmpeg:3.3-alpine -loglevel debug -i pipe: -c copy -f mjpeg -c:v mjpeg -q:v 10 -frames:v 1 pipe: | cat > test.jpg
if you can change the encoding parameter of the source file to move the idx atom at the front it solves the problem: ffmpeg -i A001_C009.mp4 -c:v copy -c:a copy -movflags faststart A001_C009-faststart.mp4 then you can pipe it to ffmpeg to extract frames of play it.
cat A001_C009-faststart.mp4 | docker run -i jrottenberg/ffmpeg:3.3-alpine -i pipe: -c copy -f mjpeg -c:v mjpeg -q:v 10 -frames:v 1 pipe: | cat > test.jpg

or you can create a buffer file from which ffmpeg will read. Since ffmpeg need the full file to be able to work, it will stream the entire file. cat A001_C009.mp4 | docker run -i --entrypoint /bin/sh jrottenberg/ffmpeg:3.3-alpine -c "cat > /tmp/buffer && ffmpeg -i /tmp/buffer -c copy -f mjpeg -c:v mjpeg -q:v 10 -frames:v 1 pipe: ; rm -f /tmp/buffer" | cat > test.jpg

@GnaphronG I finally got some time to test this out and it seems to work if I create a temp buffer. I'm trying to develop a pretty generic solution for handling pretty much all video formats that ffmpeg supports. Do you see any disadvantages with this approach vs using the http input?
Btw, big thanks for helping me

@marcuslindblom, you're welcome
The temp buffer will make the processing faster since the entire file is available locally but it takes some time to download the data, especially if the file is huge. It can also result in filling your local storage.
The HTTP approach is more flexible, since in theory it download only the part necessary to the processing. I've seen some error with certain HTTP servers when trying to access specific bytes into the file.
I'm looking at Docker Storage solution such as Flocker, or Infinit to access the data from inside a container as if it was local.

I use ffmpeg to create a "film strip" by selecting 50 frames from the video. Todo that I need to know how many frames the video have. My approach so far is to download the file locally, stream the file to the container using the ffprobe entry point. Then I use the result and the same buffer to start a second container with the ffmpeg entry point. If I want to use the http protocol the both containers need to download the same file so that would be a lot slower.

If you have access to the file locally you could mount it as volume :
docker run -i -v $PWD:/tmp/ jrottenberg/ffmpeg:3.3-alpine -i A001_C009.mp4 -c copy -f mjpeg -c:v mjpeg -q:v 10 -frames:v 1 frame.jpeg
This will mount the current folder as /tmp and export the frame into the current folder without copying anything.

Yes, that is one option but I think downloading the file without writing it to disk would be the fastest way, don't you think? I'm thinking dusk writes and reads are unnecessary
