I am using an FFMPEG component in embarcadero C++ Builder to capture video from a Direct show video camera. The capture works fine and gives me good quality mp4 files which I can play back using VLC player or FFMPEG, but the video file is not compatible with windows media player and windows won't give the nice video image when you view a file list with windows explorer.
I have seen suggestions which say you simply need to set the capture format to YUV420P, however if I do this, FFMPEG raises an exception -5 (input / Output error) and the capture device will not open.
Is there any other setting I should be looking at to allow FFMPEG to open the camera and capture the stream so media player will accept it.

I have a video device that exposes an MJPEG stream via a URL. For windows there are utility apps that can "create" a system webcam device useable by Skype or any other application based on the URL this video device exposes.
Example: smart phone is broadcasting MJPEG URL. Windows computer can run a utility app to "create" a system webcam based off of the MJPEG stream and then that webcam be used via Skype. The video shown is what the phone is broadcasting.
I'm trying to do the same but for my Mac. I can't seem to find any utility that creates a system webcam from an MJPEG stream. Googling isn't helping either, I'm just not finding a solid solution or anything I recognize as a solution.
Thanks!
I've had success with obs-studio and its vlc and virtual camera plugins.
You can add a "Vlc Video Source" and then click "Start Virtual Camera".
If you want to use it as a web-cam I just recommend that you reduce the "Network Caching (ms)" setting in the vlc video source settings as much as possible.
The hard-coded minimal value is 100ms, you can reduce it by changing this line: https://github.com/obsproject/obs-studio/blob/7217671eb0812681a9f83858bb02065b671673e7/plugins/vlc-video/vlc-video-source.c#L1079
There is still significant delay with this method regardless, but it's better than not having it working at all.
I need to show internal subtitles with android MediaPlayer.
I am playing a .ts stream, subtitles are coming on a seperate stream with DVB sub codec.
Currently working on Android 4.2.2, DVB sub is not supported with native media player.
Any Alternative?
You can take a look at Google's open source video player https://github.com/google/ExoPlayer
They don't have DVB, but you can either add your own parser or if you already have it somewhere, then just plug it to the player.
Otherwise, if you want to do it with MediaPlayer, then you need to keep track of current playback time and display the subtitles on top in a separate view.
I want to stream an audio from server using windows phone 7
the audio extension is mp3. I have tried Mp3MediaStreamSource class but the problem was that it downloads all the audio then start playing it.
I want to know what is the best way to play audio in WP7 for platform 7.0 ( with buffering -> not waiting until the entire audio file is downloaded.

Convert the stream in H264 instead of wmv. This should work.
I am developing a media player using QTKit framework in Mac OS X (v 10.6). I have used QTMovieView control for the same but there is a problem. The issue is that mov files are played perfectly but avi files and similar formats are not playing properly by properly I mean that though I have added a document type for public.avi file type but only sound is coming and there is no visual output in the player. Been trying to play the same using Quicktime (v 10) but no avail.
Could anyone point me in the right direction?
AVI as well as MOV are just movie containers. Usually a movie file contains a video track and an audio track. When in comes to playback it depends on the particular codecs used to compress the tracks. Quicktime can read AVI files, but it needs the certain codec to play the video.
You need to find out what video codec was used in your movie. There are number of apps that can display this information. For example VLC Player.
If Quicktime does not play it with default set of codecs, most likely the codec is Divx.
After you have found out what codec is used install the certain Quicktime component.
