[mythtv-users] Nuvexport, ffmpeg and x264 .mp4 fc10 issue - libx264 non monotone timestamps

[Giacomo Shimmings]

A small update...


Another similar problem has reared up here, using ffserver and streaming:


http://www.nabble.com/non-monotone-timestamp-error-to24250498.html#a24250498


And more internet searching has brought this up:


http://cekirdek.pardus.org.tr/~ismail/ffmpeg-docs/structAVCodecParserContext.html#9d513dbc8c575da415f73a7e57db250a


Which shows that with my negative dts timestamps I should expect an issue:




Presentation delay of current frame in units of AVCodecContext.time_base. 




Set to INT_MIN when dts_sync_point unused. Otherwise, it must contain
valid non-negative timestamp delta (presentation time of a frame must
not lie in the past).



This delay represents the difference between decoding and presentation time of the frame.



For example, this corresponds to H.264 dpb_output_delay. 



Definition at line 3375 of file avcodec.h.




Referenced by av_parser_init(), compute_pkt_fields(), and h264_parse().
