Bugfix

Added missing dependency for Qt5

v1.1.4

[v1.1.4]
2026.04.06

🚀 Improvements

• Added new Fronthead for Sender using FGFmpeg
• Added Multicast Support in player

v1.1.2stable

v1.1.2stable

2026_03_21

🚀 Improvements

• Audio delay display changed from samples to milliseconds (ms) for better readability
• Reduced FFmpeg RTP packet size from default 1472 bytes to 736 bytes

⚡ Latency

• Sender latency: ~3.9 ms
• Network latency:
  • ~0.5 ms (LAN)
  • ~2.5 ms (WLAN)
• Receiver latency:
  • ~2.5 ms (USB audio)

👉 Total latency: < 7 ms (when using USB audio output)

🔊 Audio Output Notes

• USB audio devices provide the lowest latency (~2.5 ms)
• 3.5 mm jack: ~30 ms latency
• HDMI: typically ~20–50 ms depending on the display

👉 For best performance, USB audio is recommended

v1.1.0

v1.1.0
2026_03_17

Realtime UDP Audio Improvements:
Removed buffer duplication for direct packet processing.
Switched to poll-based waiting for cleaner and more efficient socket handling.
On USB audio devices, ALSA buffer times below 2.5 ms are now achievable.

v1.0.14

Bugfix: Audio device detection stability

Due to dynamically changing audio device addresses during system boot or when using USB audio devices, device ordering could vary between restarts.
This could lead to incorrect or inconsistent audio device assignments.
The device detection logic has been improved:
Hardware addresses are now verified during device enumeration
Mismatches are automatically corrected when necessary
Ensures consistent and reliable audio device mapping across reboots

v1.0.12+1

v1.0.12+1
Changes

Updated README
Renamed sender script to ffmpeg_transmitter
Moved IP address and port to constants in the sender script for easier configuration

v1.0.12

v1.0.12 – Network Audio Receiver (UDP) for Raspberry Pi

🆕 New

• Installation now clean via .deb package with automatic capabilities set (cap_net_raw,cap_sys_nice+ep)
• Configuration file is created on first start at /var/lib/udp_player/

📦 Installation

• Install .deb package:

sudo dpkg -i udp_player_1.0.12.deb

- No sudo needed for running the player; capabilities are automatically set
- Uninstall removes binary, menu entry, and config folder completely

v1.0.11

[1.0.11] – 2025-12-22

Improved

• Display of the audio output device status even when no audio stream is connected.

v1.0.10

[1.0.10] – 2025-12-21

Added

• New low-CPU VU meter implementation.
• GUI now shows whether a stream is connected.
• GUI now indicates whether the audio output is ready.
• GUI displays the number of buffer duplications (not audible).

Improved

• Audio thread priority increased to 40 for better real-time performance.
• Buffer duplication during underruns optimized to further reduce audible artifacts.

v1.0.9

[1.0.9] – 2025-12-14
Removed
Removed silence handling for resynchronisation – no longer required.

Added
In the unlikely case of a missing audio block, the last valid block is repeated up to five times to prevent audible dropouts.
