Description

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.

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.

Resolution: duplicate → fixed

Errors are different than in #5088 so i'll mark it as fixed rather than duplicated.
I think "cur_dts is invalid" is an important difference.
I started with a prepared "ffmpeg version n4.2.2" package stripped from almost all modules and got that "cur_dts is invalid" error and getting no video trying to read some input file until I recompiled enabling this two parsers when calling configure:

  --enable-parser=h264
  --enable-parser=acc

In other cases this might be the problem or else it may have been fixed in this years.

Maybe this can help someone anyway.
