Video Processing via Bluetooth
16 juillet 2012, par kerim yucelThe application I am currently developing processes each frames using a native code and it should record the video as well. I tried SDK for this purpose but certain restrictions didn't allow me to do so, so I switched to NDK for a video recording code piece.
Apparently, my algorithm seriously uses CPU, upto %70 percent in the worst case. Before I actually start working on a video recorder, I wanted to try the following approach.
I will process the preview frames using an android phone and send it to another phone (which uses same application and same model) for recording. My questions are :
1.Should I try WiFi instead of Bluetooth ? I am developing the application for API 8 so I don't have WiFi-Direct, therefore I should do some socket programming, which would possibly complicate things a bit for me since Bluetooth can easily be set up using SDK.
2- Will I be available to record the frames as a video at the receiving end ? I will receive each frame with certain metadata embedded to it and should record them using the other phone. I doubt I will be able to do it using SDK, so NDK along with ffmpeg seems to be the best choice ? Any suggestions related to this question will be more than welcome.
3-Here comes the best part. I am recording the video with the lowest resolution that,after compressed, takes no more than 14mb space for a 10 minute long video. I have to reach the raw frames to send it to other end, encode and compress it. Any ideas related to possible flooding of Bluetooth/Wi-Fi because of big-sized raw frames ?
Any other approaches and answers will be much appreciated. Thanks.

converting a UYVY FFmpeg
19 février 2013, par EngineI want to read and show a video using opencv. I've recorded with Direct-show, the Video has UYVY (4:2:2) codec, since opencv can't read that format, I want to convert the codec to an RGB color model, I readed about ffmpeg and I want to know if it's possible to get this done with it ? if not if you a suggestion I'll be thankful.
