exacore's Issues

Graphics web interface

The blue border around the selected graphic is hard to recognize quickly. Perhaps make the selected item green, as the previewed is orange and the live red.

replay: previewing replay does not keep scroll back/forward time unless current preview is played

If you are scrolling back or forward on one input, but decide that a replay would be better from a different angle, you must either play the first clip, or re-scroll after selecting a second angle, to set the alignment point.

I feel like this is a small enough housekeeping task that I am able to pick up.

Include disk usage percentage and alarms in replay GUI

This is feedback from the WPI Football game.

When disk space runs out for recording video for replay, the GUI freezes without any indication of what has happened.

Showing the percentage of disk space used is important. Also, showing an error message when space has run out is useful too.

Any other build instructions?

Could anyone please make a more detailed installation guide? I get a good way to getting it installed but when I try and make replay/replay.so I get errors relating to the decklink.

I'm trying to build this on Debian Jessie.

Thanks

replay: save highlight clips with audio

Right now one can download a highlight clip as a .mjpg file, or as a .raw audio file, but the raw audio file contains the embedded audio from the camera, or possibly even nothing at all. Replay should probably be able to mux the file to something more useful (mxf?), and mux in audio from any available source. The existing buffer indexes should be able to help with this.

Attempting to do a clean build on Ubuntu 16.04 LTS

I attempted to build exacore on Ubuntu 16.04 LTS using a modified version of the README included in the repository.

# Install core dependencies
sudo apt-get install build-essential librsvg2-dev libcairo2-dev \
libfreetype6-dev yasm swig 
sudo apt-get install libjpeg-turbo

# Install rbenv and ruby 2.3.1
# Ruby 2.3.1 dependencies
sudo apt-get install -y libssl-dev libreadline-dev

# Install Git
sudo apt-get install git

# Install rbenv (rvm is no longer recommended)
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
# Compile rbenv dynamic bash extension
cd ~/.rbenv && src/configure && make -C src

# Ubuntu desktop instructions to update $PATH
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

# Follow instructions output by this step

# Open a new Terminal now.

I got the following error message and do not know where to put the DeckLinkAPI.h file for it to build.

replay: crash on controller unplugging

accidents happen during productions :)

replay crashes if monitor resolution is wrong

If the replay computer boots with no monitor plugged in, the resolution is not properly detected. This leads to a replay crash, because ReplayMultiviewer disregards the actual display resolution and just assumes 1920x1080.

Really two bugs:

ReplayMultiviewer ignores actual screen resolution
Screen resolution should be detected when program starts, not when machine boots

replay: selecting input with no captured frames causes program to slow drastically.

Bug noticed after "crash" where cam7, configured as a network input but not receiving data, was selected. Upon further observation, the program wasn't crashing, but instead spamming the console with "No frame for preview," which was causing a massive delay for all input from controller. Selecting a different camera did not stop the spamming, though marking did.

replay: capture audio from devices other than DeckLink

It'd be nice to be able to capture from USB audio interfaces, mixers, etc., freeing up SDI capture cards for video use.

replay: Support uploading of highlights and replays using Twitter video API

Twitter supports a direct video upload API (upload 30 second clips) and the ability to quickly upload instant replays and highlights as they happen has the potential to increase engagement (follows and retweets) with the RPI TV Twitter account.

API Documentation: https://blog.twitter.com/2015/rest-api-now-supports-native-video-upload

No audio

I managed to get replay working just fine now, managed to add for 1080i50 here in the UK too.

The icing on the cake now would be to get audio, could you possibly post a sample config with relevant places where audio needs enabling.

TIA

1080i50 input and output please.

Would it be possible to add 1080i50 input and output please.

I tried to bodge it together myself last year and it kind of worked, it played out on a monitor OK, bu the atem switches didn't like it but I'm almost 100% certain I had done my math wrong in the dirvers and other places I changed things.

Thanks.

Great to see some action in here, I really love this piece of software.

8-bit PNG RGBAs

Don't work.

replay: issues when buffer files are already present

Replay goes slow and starts dropping audio packets when the buffer files already exist. Not sure why this is happening. Perhaps the phase vocoder is consuming too much CPU.

avpinput_decklink: mix down audio channels

For single camera productions, where audio is run directly into the camera, often the two audio channels need to be mixed together to create a mono mix. This should be an option for avpinput_decklink.

replay audio map not loaded when mark button pressed

Steps to reproduce:

Set up audio mappings on cameras. Start replay application. Push mark button, then play button. No audio. Push mark button, then camera button, then play button and you get audio. Audio should happen regardless of whether a camera button is pushed or not.

Keyer: Need to properly handle transition commands while transition is already in progress

Basically, ignore additional "transition down" commands while a downward transition is in progress and ignore additional "transition up" commands while an upward transition is in progress.

replay: add ability to tag shots in web UI

This will eliminate having lots of shotNNN.mjpg files and make finding relevant shots a lot easier.

replay: automatically take down keyers when rolling out media files

Most of the time, the keyers are not desired during media file rollout. On-air mistakes can be avoided if these are automatically taken down.

replay: audio buffer handling

Precomputing phase vocoder parameters saves time, but the audio buffer files end up being of comparable size to the video buffers! Also, this makes it difficult to extract unprocessed audio later. Perhaps the phase vocoder data should be computed on playback rather than on recording. This may lead to sync issues though.
