# Errors
@ -59,8 +59,8 @@ RTSP feeds from certain cameras (such as TechView ones) do not
generate presentation timestamps (PTS), resulting in errors such as
the following:
* [mpegts @ 0xX] Timestamps are unset in a packet for stream 0...
* [mpegts @ 0xX] first pts value must be set
* [mpegts @ 0xX] Timestamps are unset in a packet for stream 0...
* [mpegts @ 0xX] first pts value must be set
This can be fixed with an ffmpeg video filter (specified by flag 0x0001).
Another issue is that MPEG-TS continuity counters may not be continuous.
