#7631: Segmentation fault with HLS var_stream_map -------------------------------------+------------------------------------- Reporter: pero | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hello, I have one video in 4 different resolution. They are ismv mp4 files. I'd like to convert them to hls with var_stream_map. At the end of the conversation FFmpeg dies with segmentation fault. All files are generated successfully, only the master playlist file has zero content.

#7631: Segmentation fault with HLS var_stream_map -------------------------------------+------------------------------------- Reporter: pero | Owner: Type: defect | Status: new Priority: normal | Component: Version: git-master | undetermined Keywords: | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Comment (by JEEB): Please re-build your FFmpeg with "--disable-stripping" set during configure, or if you still have the ffmpeg_g binary around, try running it under gdb. Crash course: 1. "gdb path/to/ffmpeg(_g)" 2. Wait until you see "symbols loaded" (if symbols cannot be found, exit with ctrl+D and re-build with disable-stripping) 3. "run -your -parameters -here" 4. Wait for crash. 5. "bt full" After this you can post the result of "bt full" here. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7631#comment:1> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
