GPS tag @ img.janforman.com and videos from janforman.com in the map.
EXIF header is parsed while uploading and when geo tag is found then application sends it to REST-API with DB backend.

geographic data exported to map:
a) images from img.janforman.com – based on JPEG / EXIF GPS tag.
b) video – based on DB value.

* update – fixed North/South/West/East EXIF tag (added minus sign to result wich is sended to REST service each time while frontend detect GPS tag)

Changelog:

Video streaming bandwith control (fast start and then limit bitrate)
RSS Feed for video channel fixed
Added monoscope to live broadcast (uplink not running)
Facebook login / work in progress
Flash video player remake (35KB size)

Nokia 5800 XpressMusic can accept only MPEG4 legacy format for smooth playback in 640×360 resolution.
You must have ffmpeg installed (i’am using one from SUPER encoder).
As you can see this is very easy and output video have excellent quality due to 2-pass encoding.
Picture is better than standard definition TV and is 16:9…
Deinterlace and subtitles can be included – watch remarks.
mkv x264 / ac-3 rips working just fine, enjoy ;-)

Place this code to file (example C:\WINDOWS\encode.bat) and easily type in prompt “encode.bat video.avi”… then wait and c:\final.mp4 file may appear.
Yes you can easily change this script for LINUX ;-)

x264 Features:
* CAVLC/CABAC * Multi-references * Intra: all macroblock types * Inter P: all partitions * Inter B: partitions from 16×16 down to 8×8 * Ratecontrol: constant quantizer, single or multipass ABR, optional VBV * Scene cut detection * Adaptive B-frame placement * B-frames as references / arbitrary frame order * 8×8 and 4×4 adaptive spatial transform * Lossless mode * Custom quantization matrices * Parallel encoding on multiple CPUs * Interlacing

Here is my recommended values for x264 (H.264 – MPEG4 AVC) encoder

For better visual quality and improved compression ratio I’m using
MSU Graphics & Media Lab Denoiser

MainConcept MJPEG (Motion JPEG) have great quality on 90%
(600MHz CPU is enough for 720×576, also this is good for HD)

HuffYUV for lossless compression :-) ehmm yes this produce big file.
