Convert DAV to MP4 and OGG
I want to prepare a web page containing films from camera recorders. Each recorder transmits video files in DAV format, so each movie is converted to MP4 format per script using this syntax:
ffmpeg -y -i movie.dav -vcodec libx264 -crf 24 movie.mp4
So, I included this entry in the HTMLv5 code:
<video width="320" height="240">
<source src="movie.mp4" type="video/mp4">
</video>
It works correctly with Chrome, but not Firefox. To work correctly in FF, you need to add a link to the OGG file. Therefore, the correct HTMLv5 syntax for both browsers should look like this:
<video width="320" height="240">
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
</video>
Can anyone help me pass the correct ffmpeg syntax to generate the OGG file?

I have an answer, just try it.
Install this Nuget NReco.VideoConverter
Package Management Console
Install-Package NReco.VideoConverter -Version 1.1.2
and this method to convert
var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
ffMpeg.ConvertMedia(inputfile.dav, "output.mp4", Format.mp4);

I just had to solve the same problem and I actually found a solution even if not using ffmpeg.
I've tried this on Windows, but I think it won't make any difference if done on Linux.
To convert .dav files I used VLC like this:
1) Go to Tools -> Preferences in the VLC toolbar.
2) Then select "All" in the "Show Settings" box in the lower left corner.
3) Go to the "Demultimeters" section and switch from "Automatic" to "H264 Video Driver" and "Save". 4) Then again from the VLC toolbar go to Media -> Convert / Save ...
5) Select "Add" and select the file you want to convert.
6) Click the arrow on the "Convert / Save" button and select "Convert"
7) Then select "Destination File" in the section below by clicking the "Browse" button
8) Finally click "Start" and wait for the VLC progress bar to be full.
At this point, the file should be successfully converted.
Anyway, after step 3, you should already be playing the .dav file, to make sure it is not damaged, try playing it first.
Hope the answer is helpful to someone and I wish you all a good day :)
EDIT: This answer is of course not entirely related to the question, because I don't know if any information is useful for web pages: \ so, sorry for not staying exactly on the topic
