v0.18.0
f71b7d8

New major features

  • General: support H264 streams with dynamic SPS / PTS, i.e. streams with a resolution that changes over time. This is particularly useful when dealing with IP cameras, whose resolution can be changed into their settings page
  • RTSP server/source: parse all incoming RTP/RTCP packets. This allowed to solve a series of long-standing issues that required a deeper understanding on what exactly is routed by the server, including:
    • remove padding from outgoing RTP packets, saving bandwidth
    • generate RTCP sender reports automatically; stop routing RTCP packets from publishers to readers
    • automatically remux oversized RTP/H264 packets into smaller packets; remove parameter readBufferSize since it is not necessary anymore
    • fix computation of RTCP sender report timestamps, RTCP receiver report timestamps and timestamp of the RTP-Info header, in case of H264 streams with B-frames. This prevents timing issues with FFmpeg and a lot of other software (#622)

Fixes and improvements

  • General: fix panic that happened when integer keys are used in config maps (#865)
  • General: (breaking change) remove runOnPublish; it is replaced by the more generic runOnReady
  • General: add upper limit on H264 NALU size and AAC AU size in order to prevent RAM exhaustion
  • RTSP server: set timeout in Session header only when client is playing
  • RTSP server: remove Session header from ANNOUNCE responses, supporting some additional clients (#840)
  • RTSP server: set multicast TTL to 16 (#873)
  • RTSP source: skip tracks with an invalid clock rate (#832)
  • RTSP source: support servers that sends UDP packets with a different IP
  • RTSP source: support IOI trk-101 (bluenviron/gortsplib#116)
  • HLS muxer: fix blank screen on iOS / Android in case of video-only streams (#816)
  • HLS muxer: fix format of EXT-X-PROGRAM-DATE-TIME
  • HLS muxer: fix computation of last PTS of segments
  • HLS muxer: fix (again) DTS computation
  • HLS source: support segments with relative URLs
  • HLS source: fix freeze that happened during a video decoding error
  • HLS source: ignore Annex-B decode errors
  • RTMP server: always send H264 configuration before IDR frames
