#11584: ffprobe returns "n/a" for bitrate in opus audio file -------------------------------------+------------------------------------- Reporter: jr_clifton | Type: | enhancement Status: new | Priority: normal Component: ffprobe | Version: 6.1.1 Keywords: ffprobe | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I try to query the bitrate of the opus encoded audio file and it gives me N/A for the bitrate. $ ffprobe -v error -show_format -show_streams cath.webm (see the putput bellow) I understand that this is probably due to the fact that this info is not written in the header.

The biCompression field is zero, which corresponds to BI_RGB (uncompressed RGB). This AVI file does not play and may cause some players to crash. How to reproduce: {{{ % ffmpeg -f lavfi -i testsrc -t 30 -pix_fmt yuv420p -c:v libx265 output.avi }}} ffmpeg version 2025-04-23-git-25b0a8e295-full_build-www.gyan.dev Copyright (c) 2000-2025 the FFmpeg developers Yes I understand that saving HEVC video to AVI file is a bad idea. But FFmpeg does not write any warnings or errors for this case. The error can be fixed by adding the "-vtag HEVC" parameter, but I think it should have happened automatically, as it does for the libx264 encoder. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11556> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#11492(ffmpeg:new): Support for QuickTime skin file

#11492: Support for QuickTime skin file --------------------------------+--------------------------------------- Reporter: spixi | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------+--------------------------------------- Summary of the bug: Early versions of QuickTime player allowed videos with “skins”. The “skins” themselves where contained directly in the video stream. The skinned videos came with a special XML file, but with the .MOV extension. This file refers to the actual video file, a window mask (contentregion, black = visible, white = transparent) and a drag mask (dragregion, black = draggable [that means the mouse becomes a drag cursor if you move over this area], white = not draggable). Allowed file formats for this masks are gif, tif and png. contentregion and dragregion can refer to the same file. An example file could look like this: {{{ <?xml version="1.0"?> <?quicktime type="application/x-qtskin"?> <skin> <movie src="actual_movie.mov"/> <contentregion src="contentregion.png"/> <dragregion src="dragregion.png"/> </skin> }}} Currently, such a file is not supported. FFMpeg should at least open the referred actual_movie.mov when you load such a file. It would also be nice to have, when the contentregion is applied to the video as a simple alpha mask. The dragregion can be ignored. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11492> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
