#9346: failed with error info "partial file" when input a mp4 file via unix socket -------------------------------------+------------------------------------- Reporter: ku7iex2E | Owner: (none) Type: defect | Status: new Priority: normal | Component: | undetermined Version: unspecified | Resolution: Keywords: unix-socket | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Comment (by dank074): I have also encountered this bug using `Ffmpeg version 6.1.1-3ubuntu5` It seems that there is loss of data when using a Unix Domain Socket as input. A chunk of initial bytes are lost. I created sample script to reproduce the bug here: https://github.com/dank074/ffmpeg-unix-socket-bug In my sample code I generated two outputs: one using the sample file as input directly, and the other using a Unix Domain Socket as input which contains the same file. The resulting output from the Unix Domain Socket input is missing 65536 bytes of data when compared to the same ffmpeg command that uses the original file as input. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9346#comment:2> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
