ffmpeg muxing error, no video packets muxed: cur_dts is invalid (this is harmless if it occurs once at the start per stream)

[leo.z]

Hi all

I'm using ffmpeg to recode a live mpegts stream, but no video packets muxed, the debug log keep saying: cur_dts is invalid (this is harmless if it occurs once at the start per stream).
the source file recoded using others tools: ​http://203.118.245.62/hd_spts.ts.
the ffmpeg report file: ​http://203.118.245.62/ffmpeg-20160323-065632.log

i have looked into the code, it seems there are something wrong with the AVPackets which av_read_frame returned, the dts/pts value was set to AV_NOPTS_VALUE of the every other returned AVPackets, kind of divided one frame to two AVPacket.

would you please take some time looking into it, thanks.

Feel free to reopen this ticket if you can provide the command line that allows to reproduce this issue together with the complete, uncut console output.

Please look at this iptv sample:
​https://drive.google.com/file/d/0B0laIcbq4vKRV1g0c1B4NGREZ1E/view?usp=sharing

ffplay can show the video, but ffmpeg cannot copy it using this command line:

ffmpeg -report -y -ss 5 -i iptv-raw -t 30 -c copy /tmp/a.avi

The diagnostics looks very similar to the report of the topic starter.
