scheutzo <[email protected]> added the comment: Analysis of this bitstream by non-ffmpeg tools shows that it contains a substantial number of bitstream errors: about 2% of the transport stream packets are marked as "errored", and an additional 1% are simply missing.
These errors were likely caused by a very weak satellite signal, or defective electronics, and the demodulator could not stay locked. In the original, no-error bitstream, every video frame appears to have had a DTS/PTS timestamp. So the complaint - non-monotone timestamps - is a side effect of the ffmpeg transport stream demuxer trying, but failing, to extract video data from an input stream with severe packet errors. A general fix for this situation probably not possible, although this sample is an interesting for checking error-robusteness. ---------- nosy: +scheutzo ______________________________________________ Libav issue tracker <[email protected]> <https://roundup.libav.org/issue1551> ______________________________________________
