We are using camera2 API to get preview and encode video simultaneously, using mediacodec. We know when we should rotate the camera by querying 'CameraCharacteristics.SENSOR_ORIENTATION' but there ...

I want to write an encoder with ffmpeg which can put iFrames (keyframes) at positions I want. Where can I found tutorials or reference material for it? P.S Is it possible to do this with mencode...

Is it possible to create an MP4 video on a browser through JavaScript? (I know it is now possible in Flash with FlashyWrappers) Ideally, I will be feeding it with image frames (raw, PNG or an...

I want to concatinate 4 different videos of 4 different resolution and type into 1 video which can be played in android. I am using ffmpeg ported on android using https://github.com/guardianp...

I'm working on a project that need to record and playback with Opus Codec, I search a lot but I can't find any demo/example using that solution. I find a demo having encoder but can't find the deco...

I've been rendering video through the MediaCodec directly to a Surface that was taken from a SurfaceView in my UI. This works great. I am now attempting to use MediaCodec as an encoder. As a test,...

Preambule: This may sound like a very specific question, but this is actually a go / no go to build an API 16+ Android application using MediaCodec that is compatible with most phone. I have an ap...

I am using a custom Texas Instruments OMAP-L138 based board that basically consists of an ARM9 based SoC and a DSP processor. It is connected to a camera lens. What I'm trying to do is to capture l...

I'm trying to use MediaCodec to encode frames (either by camera or decoder) into a video. When processing the encoder output by dequeueOutputBuffer(), I expect to receive the return index = MediaCo...

I have written a H264 Stream Encoder using the MediaCodec API of Android. I tested it on about ten different devices with different processors and it worked on all of them, except on Snapdragon 800...

I need to create video from images, I have seen jcodec and I think it is what I need: http://jcodec.org/ How do I add jcodec to my project? I have seen there is a version for android. Correct me i...

Ideally I'd like to accomplish two goals: Pass the Camera preview data to a MediaCodec encoder via a Surface. I can create the Surface using MediaCodec.createInputSurface() but the Camera.setPrev...

So far I am able to setup a MediaCodec to encode a video stream. The aim is to save my user generated artwork into a video file. I use android Bitmap objects of the user artwork to push frames int...

Could you tell me if there is a better way to write a priority encoder in VHDL than just using if-else statements? I mean, I have got this code and it works, but could it be written shorter? Switch...

Does anyone knows of any implementation of the hierarchical JPEG mode (ITU T.81) ? I am not talking about progressive mode (or sequential), I really mean the hierarchical mode.

I am trying to convert an image to an icon. My function is: private Icon GenerateIcon(int width, int height) { using (Bitmap icon = _backingImage.GetThumbnailImage(width, height, () => false, ...

I'm having trouble getting a rotary encoder to work properly with AVR micro controllers. The encoder is a mechanical ALPS encoder, and I'm using Atmega168. Clarification I have tried using an Ext...
