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

Please provide the command line that allows to reproduce the issue together with the complete, uncut console output here on the bug tracker to make this a valid ticket: External resources may disappear.

I'm using command "ffmpeg -y -i hd_spts.ts -c copy 1.ts -report", just try to remux it.
I had uploaded the source video, report log file and the dts/pts analyze form:

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.

I believe this is a duplicate of ticket #5088.

[aalku]

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.
