Classes
class	H264Decoder
	Template class for decoding H.264 streams to raw video frames. More...
class	H264Encoder
	Template class for capturing frames from ESP32 camera and encoding to H.264. More...
class	PSRAMAllocatorH264
	STL-compatible allocator that prefers PSRAM allocation with fallback. More...
class	RAMAllocatorH264
	STL-compatible allocator that uses internal RAM (DRAM) allocation. More...
class	RDPPacketizer
	RDPPacketizer class to packetize H.264 NAL units into RTP packets. This class takes raw H.264 NAL units (in Annex-B format) and packetizes them into RTP packets suitable for streaming over UDP. More...

H264DecoderPSRAM

using H264DecoderPSRAM = H264Decoder<PSRAMAllocatorH264<uint8_t> >

Type alias for H264Decoder using default PSRAM allocation.

Provides a simpler way to declare H264Decoder instances without specifying the allocator template parameter. Uses PSRAMAllocatorH264<uint8_t> by default.

Example usage:

H264DecoderPSRAM decoder(&udp);  // Instead of H264Decoder<PSRAMAllocatorH264<uint8_t>>

H264DecoderRAM

using H264DecoderRAM = H264Decoder<RAMAllocatorH264<uint8_t> >

Type alias for H264Decoder using internal RAM allocation.

Provides a simpler way to declare H264Decoder instances that use fast internal RAM instead of external PSRAM.

Example usage:

H264DecoderRAM decoder(&udp);   // Instead of H264Decoder<RAMAllocatorH264<uint8_t>>

H264EncoderPSRAM

using H264EncoderPSRAM = H264Encoder<PSRAMAllocatorH264<uint8_t> >

Type alias for H264Encoder using default PSRAM allocation.

Provides a simpler way to declare H264Encoder instances without specifying the allocator template parameter. Uses PSRAMAllocatorH264<uint8_t> by default.

Example usage:

H264EncoderPSRAM encoder;  // Instead of
H264Encoder<PSRAMAllocatorH264<uint8_t>>

H264EncoderRAM

using H264EncoderRAM = H264Encoder<RAMAllocatorH264<uint8_t> >

Type alias for H264Encoder using internal RAM allocation.

Provides a simpler way to declare H264Encoder instances that use fast internal RAM instead of external PSRAM.

Example usage:

H264EncoderRAM encoder;   // Instead of
H264Encoder<RAMAllocatorH264<uint8_t>>

PSVec

using PSVec = std::vector<T, PSRAMAllocatorH264<T> >

Convenience type alias for vectors using PSRAMAllocatorH264.

PSVec provides a shorter way to declare vectors that use PSRAMAllocatorH264.

Template Parameters

T	The element type of the vector

Example usage:

PSVec<uint8_t> buffer;  // Instead of std::vector<uint8_t,
PSRAMAllocatorH264<uint8_t>> buffer.resize(1024);

RAMVec

using RAMVec = std::vector<T, RAMAllocatorH264<T> >

Convenience type alias for vectors using RAMAllocatorH264.

RAMVec provides a shorter way to declare vectors that use RAMAllocatorH264.

Template Parameters

T	The element type of the vector

Example usage:

RAMVec<uint32_t> buffer;  // Instead of std::vector<uint32_t,
RAMAllocatorH264<uint32_t>> buffer.resize(256);
