[mpegts @ 0xb739d2e0] Application provided invalid, non monotonically increasing dts to muxer in stream 1: 5263997382 >= 5263993782

[derekzhuo]

does anyone know how these happen, and how to solve this?

which is caused by the api: av_interleaved_write_frame()

many thanks.

I guess You are setting invalid values to the PTS fields of frames You want to mux. Find proper muxing example (I believe there is one in FFmpeg folder doc), and check how it is done. You need to take care of time base, and use it to calculate proper PTS values from Your frame rate, in a given time base (for TS it is always 1/90000).

Thanks, but it doesn't always happen, some input stream work fine, while some not, is there any chance that the input stream carry problems?

[Obucina]

If You are just trying to remux some stream, and do not try to calculate PTS/DTS values, then probably stream contains values which FFmpeg consider as invalid.
