#227(FFmpeg:new): Extend -ss and -t to support seeking to EOF time position (and backwards)?

#227: Extend -ss and -t to support seeking to EOF time position (and backwards)? --------------------------+--------------------------------------- Reporter: burek | Owner: michael Type: enhancement | Status: new Priority: wish | Component: FFmpeg Version: git | Keywords: seeking eof time position Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 --------------------------+--------------------------------------- Maybe, it would be useful if options -ss and -t could support something like this: ffmpeg -ss EOF-00:00:10 -i input ... (meaning the start time is 10 seconds before the end of the file). This would be useful in automated use of ffmpeg, where users don't need to set time positions absolutely (manually), but rather relatively to the end of file. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/227> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#933(FFmpeg:new): A/V desynch when transcoding A/V files with timestamps non starting from 0 with -copyts

#933: A/V desynch when transcoding A/V files with timestamps non starting from 0 with -copyts -------------------------------------+------------------------------------- Reporter: saste | Owner: Type: defect | Status: new Priority: normal | Component: FFmpeg Version: git- | Keywords: timestamp master | desynch mpegts Blocked By: | Blocking: Reproduced by developer: 1 | Analyzed by developer: 0 -------------------------------------+------------------------------------- Using the command: {{{ ffmpeg -vsync 0 -copyts -i columbia-intro.ts -acodec libfaac -y columbia- intro.out.ts }}} (same without -vsync) the A/V streams in the output file result desynched, and will result in the video being unplayable. This seems due to the first audio packet timestamp information not being correctly propagated to the encoder (and to the muxer), and being set to 0, so that ffmpeg will fill the first part of the file with audio packets, and the probe will fail since ffmpeg can't detect video frames in the probed initial part of the file. Same result in case I use the -copyts with no -vsync. If the output file only contains video (e.g. if the -an switch is used) the output file seems to be correctly generated (playable and with correct timestamp information). I'm attaching a sample file and log obtained by adding debugging print in ffmpeg.c. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/933> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Also, on yet another CentOS box I am using a several-year-old version of ffmpeg that was compiled ages ago which can decode the same amr files just fine. So either the error message is completely wrong and the real problem with the files is different, or there has been some regression in that a feature that had already been implemented ages ago has been dropped. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/232> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
