#3997: Endless loop when seeking past the end of an incomplete wtf file -------------------------------------+------------------------------------- Reporter: gjdfgh | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Start an incomplete wtv file with ffplay, and click close to the right border of the screen. Since the duration is apparently stored in the file header, doing this will seek past the end of the file. It will enter an endless loop in the demuxeR: {{{ [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2455 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2470 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2478 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2500 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2513 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2480 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2519 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2552 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2588 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2505 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2505 times [wtv @ 0x7fffd8000940] encountered broken chunkKB sq= 112B f=0/0 Last message repeated 2530 times }}} Get the sample file from https://app.box.com/s/ofjnj0vnqqgkojv545xa (not my upload). -- Ticket URL: <https://trac.ffmpeg.org/ticket/3997> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

This isn't your first ticket, and I don't remember one that we could solve without a sample and without the necessary information. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3991#comment:6> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
