Kwikflix UDP send

sendts

Features

• Sending ts file(s) as a ts udp stream

• If there is no files to send, it sends null packets

• Works with real-time process/threads priorities to provide stability of the stream

• Works with FIFO files

• Reading files to a cache buffer with an accumulation part to provide stability of the stream

Tested environments

• Debian Jessy

• Ubuntu 14.04 LTS with lowlatency kernel (sudo apt-get install linux-lowlatency and restart system). It provides really stable TS stream.

Build

Just run make in the project directory

Command-line options

• -i <address> - ip address to send packets

• -p <port> - port to send packets

• -b <bitrate> - bitrate of stream

• -d <path to directory> - send all files from a directory, sorted my modified time, the directory is scanned in real-time, you can add files on fly

• -f <path to file> - send one file, you have to select either a file or a directory

• -s <number> - common cache size, you can use K to set the size in kilobytes and M in megabytes

• -a <number> - size of filled cache part, you can use K to set the size in kilobytes and M in megabytes

• -t <number> - set ttl

• -P <number> - set the process/thread priority

• -u <number> - the number of ts packets in one udp packet

• -c - don't stop file reading if it read zero bytes, use it for FIFO files

• -m - print debugging messages on the screen

• -l <file name> - save debugging messages to a file

• -D <seconds> - print the state of buffer in some delays (in seconds)

• -F <file size> - set a minimal file size that we're waiting for, you can use K for kilobytes and M for megabytes

• -M - set a minimal file size, based on accumulation buffer size (accumuluation size + 25% of it)

• -v[0-3] - verbosity level

###Verbosity

• -v0 - prints nothing

• -v1 - prints minimal information about processing

• -v2 - prints information about buffer state with one second delay

• -v3 - prints debugging messages

###Examples

####Read files from a directory

sudo /opt/sendts/bin/sendts -d /ts -i 239.0.0.10 -p 1234 -l ./log --ts_in_cache 40000 --accumul_ts 20000 -b 2000320

####Read and stream file, generated by ffmpeg

sudo /opt/sendts/bin/sendts -f /ts/channel1.ts -i 239.0.0.10 -p 1234 -l ./log --ts_in_cache 40000 --accumul_ts 20000 -b 2000320 -c -F 9520000

Above command will read /ts/channel1.ts file and send it as UDP stream with constant bitrate of 2000320.

####Generating proper mpegts stream with ffmpeg v2.8

ffmpeg -nostdin -i rtmp://XXX.XXX.XXX.XXX/pool/channel1 -xerror -err_detect explode -copytb 0 -vsync 0 -c copy -mpegts_original_network_id 0x1122 -mpegts_transport_stream_id 0x3344 -mpegts_service_id 0x5569 -mpegts_pmt_start_pid 0x1500 -mpegts_start_pid 0x150 -metadata service_provider="My Company" -metadata service_name="Channel1" -muxrate 2000320 -bsf:v h264_mp4toannexb -f mpegts -y /ts/channel1.ts

/ts/channel1.ts can be simple file or fifo (IMPORTANT NOTE: We are not recommending using fifo until we found solution to prevent sending garbage data)

Contribution

Code must be formatted with Artistic Style Utility: http://astyle.sourceforge.net/

Astyle is command-line utility and you have to use such options to format: ./astyle sendts.c -p -c -xC110 -xe -k3 -A14

We reject contributions that aren't being formatted with astyle.
