You need to convert the codec used to encode the video to something that the players you are trying to use support. MPlayer supports a wider range of codecs than many players. To allow you to view the video in other players you need to transcode the video using an application like ffmpeg. The command below will provide the conversion you need: ffmpeg -i ...

You should just be able to place it in a MP4 ffmpeg -i foo.264 -c copy foo.mp4 Maybe if they don't detect the format, then ffmpeg -f h264 -i foo.264 -c copy foo.mp4

The information realted to input files seems perfectly fine. Can you share the file or file link here. I will experiment with it and update you about the results.

Why don't you stream to YouTube? That's free. Make your stream/"event" private. Then it's ready instantly once the "event" ends because there is no waiting period. Then serve that embedded player on your website. This is very flexible and free (less camera and computer expense). No reason to build your own sever ... Maybe eventually, but the YouTube service ...

As mentioned by @Mulvya, I think the issue is the "slow" preset. One option is encoding a compressed stream that is also lossless. For example, the x264 encoder can do this using "-preset ultrafast -qp 0". This will probably result in failing your 3rd requirement (compatibility), but since it's lossless, you can transcode later onto cheap spinning disks. ...

Short answer is No. Longer answer is, it depends. If you're encoding a file, then generally the output is the duration of the input, unless there's speed change or trim filters or -ss, -to, -t options applied. For a live input, FFmpeg will stop the encode when it encounters EOF on the input, so unless you know that, you won't know the output duration. For ...

Definitely, it will degrade the video quality after many times of converting. I advise you to convert the file to the one with original settings. The best choice is to use a video editor which allows you to edit and convert files to desired ones.

What are the limitations of AAC-HE codec while doing 5.1 audio ? HE-AAC v2 can only encode stereo from my experience with Nero AAC and the article in Wikipedia about Parametric Stereo. Why is AC3 preferred when compared to AAC-HE ? Which case are you actually talking about? Are you sure it's HE-AAC not AAC-LC? Dolby Digital / A/52 / ...

All codecs, unless they are truly lossless, suffer from concatenation errors. Every time you encode with a codec, decode, and re-encode with the same or a different codec you will degrade the quality of the video. It isn't as precise to figure out just how bad it will be as when you could count the generational loss of re-recording to tape as the source and ...

Yes. By definition, any time you save an audio or video file using a LOSSY compression scheme, you will lose something (by definition). Now, modern codecs have been getting better at minimizing perceptible losses. But it is always preferable to avoid ANY extra compression steps. Until the project is completely finished and ready for distribution, it is ...

If the codec is not lossless, such as Quicktime Animation Codec; true lossless, then yes. But if you are using a good encoder, I would gather even after 100 generations of degredation would you be able to even visually see the difference if you continually re-encoded the file outputs using MP4 at a high bitrate- say 30mbps for 1080p. Lower bitrates, ...

MP4 isn't an ideal format for intermediate saves. If you know you'll be re-opening the file, save it as losslessly as practicable, and use MP4 only for the final output. That said, depending on the encoder and settings you probably don't lose much if anything on subsequent saves. MP4 and similar codecs work by decimating the higher frequencies (details, ...

Yes. Every time you "save" video in video-editor, you will re-render it with codec. Most codecs lose some video information for compression. So, every time you will lose some more information.
