Re: BOM Raspberry Pi 2

Thanks for replying! You was right, the problem wasn't what I thought. I found a partial schematics for the RPi B+ that includes the circuit for the "PWR" LED. I think the circuit for the "ACT" LED must be the same, so it shouldn't affect the Rpi performance. https://www.raspberrypi.org/documentatio...

BOM Raspberry Pi 2

Hi! I haven't found the BOM (Bill Of Materials) for the Raspberry Pi 2. I read somewhere you haven't released it and I need that information, or at least, the manufacturer part number of 2 components. I accidentally broke the "Q6" component (I think it's a transistor) and the "ACT" LED, and now my R...

Re: Convert video h264 to mp4

How can I compensate with raspivid or ffmpeg commands? man avconv -r[:stream_specifier] fps (input/output,per-stream) Set frame rate (Hz value, fraction or abbreviation), (default = 25). So in theory something like: avconv -i input.h264 -vcodec copy -r 252/100 output.mp4 should work, but I don't ha...

I am working with a RP model B.

When I record a 20 seconds video, the duration of the final video (mp4) is 20.24 seconds.

Re: Convert video h264 to mp4

(This is where I start hating the manufacturers of the camera board) The sensor is programmed on the basis that it is fed with a 24.8MHz clock as that was the original design, with that coming direct from the Pi down the ribbon cable. When the module went for EMC testing, that configuration failed,...

Convert video h264 to mp4

Hi, I have some problems when converting a video from h264 to mp4. Can you help me? First, I record a video with the next options: with picamera.PiCamera() as camera: camera.resolution = (640,480) camera.framerate = 25 camera.start_preview() camera.start_recording('video.h264', intra_period=25) star...
