ogg

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I am using ffmpeg to convert audio and video on my website. Ffmpeg is properly converting to other formats like mp3, mp4, etc. but not converting properly to ogg. Although ffmpeg is creating the ogg file but the newly created ogg file is corrupted and too much bigger in size than the original one. I am using the following PHP code to convert to ogg. exec("/usr/bin/ffmpeg -i ".$_FILES['thefile1']['tmp_name']." .

I know one difference between ogg video and mp4 video is that ogg video doesn't have metadata describing the file size, so when an ogg video is loaded, the controls can't show the time remaining until the file has fully loaded. This can be a problem if the ogg video is more than a few minutes long. Is there a way to get this filesize when the page is requested? (Client-side developer, asking a question that I think has a server-side answer. I welcome suggested edits to this question, if you can think of a way to ask it more specifically.) Well although not the most direct, you could try this.

Just to start off, this question does seem very similar to another post Add the DLL (lame_enc.dll) reference to my project , but I haven't been able to successfully apply that answer. I am pretty new to VB.NET so it is very possible I'm simply missing something obvious. I am trying to link a DLL to a VB.NET 2010 project to allow my VB app to play *.ogg files. I followed some other advice here on the forums and downloaded FMOD's FMOD Ex Programmers API . I am trying to now reference that functionality. These appear to be the files I need to somehow reference. C:\Program Files (x86)\FMOD

I was doing some audio analysis stuff with Jupyter and tried to play .ogg files with IPython.display.Audio . Since PyCharm often failed to open big .ipynb files, I mostly used web browser to view my Notebook files at localhost:8888 . This picture is what I get with Chrome. As you can see, FailToDisplay.ogg is taken from my work, the audio play bar is not activated. File-ACDC_-_Back_In_Black-sample.ogg and song sample.mp3 are all downloaded from Internet. The integrity of 3 files are all validated, i.e., they can all be played correctly with audio players. I also tested it with Microsoft Edge

So, I'm building a website on which users can upload an watch videos. I'm using the standard HTML5 video player ( <video...> <src>... ) Currently, I use multiple sources: MP4, OGG and WEBM, for cross-browser compatibility Due to the fact that maintaining three formats is both CPU intensive (converting) as well as eating away precious disk space, I started searching the need to find out whether it's really needed to support this three formats According to the chart I found on Wikipedia ( http://en.wikipedia.org/wiki/HTML5_video ), OGG and MP4 should be sufficient, as all browsers seem to be

I need to convert a continuous stream of PCM, or encoded audio (ADPCM, uLaw, Opus), into MP3/OGG format so that it can be streamed to a browser (using html's audio tag). I have the "stream-mp3/ogg-using-audio-tag" part working, now I need to develop the conversion layer. I have two questions: How can I convert PCM into MP3/OGG using NAudio and/or some other C# library/framework? I assume there is a code snippet or two in the NAudio demo app that may be doing this, but I haven't been able to find it. Do I have to convert the encoded data (ADPCM, uLaw, OPUS) into PCM (which I can) before I
