Re: ffmpeg usb microphone choppy/stuttering.

After looking around, I solved my own problem. And even removed some of the high pitches of the USB microphone. Here's the command: rec -d -t wav - pitch -300 band 1.2k 1.5k | ffmpeg \ -re -i http://192.168.13.2/0.flv \ -thread_queue_size 50 \ -ac 1 -i - -acodec aac -ar 44100 -ab 128k -strict experi...

Re: Skipping raw h264 frames with gst-launch gst-launch-1.0

It's too hard for me, unfortunately. I decided to buy an external hdmi encoder from aliexpress, and connect it to a usb ethernet port on the rpi3. rpi3 will pick up the flv stream from the encoder and broadcast it directly to youtube. This way each device is doing it's job and I won't be hitting any...

ffmpeg usb microphone choppy/stuttering.

I use ffmpeg to broadcast a stream from an external encoder to youtube. I do not reencode the video (I use -vcodec copy), but I inject the audio from a USB microphone attached to the rpi3: ffmpeg -re -i http://192.168.13.11/0.flv \ -thread_queue_size 50 \ -f alsa -ac 1 -i hw:1 -acodec aac -ar 44100 ...

Re: Skipping raw h264 frames with gst-launch gst-launch-1.0

bcm2835-v4l2 is still using the firmware, the same as raspivid. Support will not be forthcoming on the HDMI capture board via the firmware. And the simple answer is that no you can't skip H264 frames as they will be used as reference frames for subsequent frames. There is an option within MMAL/IL t...

Skipping raw h264 frames with gst-launch gst-launch-1.0

I have a v4l2 /dev/video0 which outputs a h264 video stream. Since I'm using a Auvidea B101, the output h264 stream has weird fps - somewhere around 48. 2 questions: 1. Is is possible to limit the stream to 25 fps with gst-launch-1.0 without reencoding? 2. Is it possible to drop the fps twice with g...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

Firstly, as stated so many times, using raspivid with the B101 is unsupported. Thank you for this. I have managed to get an almost perfect 25fps live stream to youtube from Auvidea b101 on my raspberry pi 3. Here is the command: modprobe bcm2835-v4l2 ffmpeg -f video4linux2 -framerate 25 -video_size...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

raspivid (and v4l2-ctl if using bcm2835-v4l2) will be saving an H264 elementary stream. Elementary streams have no timestamp or frame rate information within the stream. The application you are using to convert it into a container is therefore having to make an assumption, and that is normally 25fp...

Re: AuVidea HDMI-In boards

Hello!

I'm interested in the B101. How fast can you ship to Thailand?

Password issues

Hello all people, I just got used a raspberry pi 2 model b, and it does not let me change the password! But if you type mount -rw -o remount / before typing passwd pi , it will let you change your password. Should work easily :D :) ;) If the mount gives you an error (can't find PARTUUID), do: mount...
