Weird "end of file" bug ?
I was playing with tvbars.ogg It goes from 2077 to 2099 But if you load it with Theora decoder there will be extra black frame near the end! i deleted it while locking audio. If you go with default ffmpeg decoder - last frame will be black! If i render corrected theora-decoded file as v410/s32 QT - I got weird diff between audio and video! If I disable write_tcmd in qt format (muxer) option A and V finally same length and video plays to 2099 framecount (on screen) But audio still few frames short! Anyone can replicate such strangeness?
I would like to try to replicate this. Andrew, could you send just me the exact file you are using or is it already on your website that I can download it easily? I do not see this problem with the tvbars I have yet. On Tue, Dec 23, 2025 at 12:19 AM Andrew Randrianasulu < [email protected]> wrote:

Are you testing 64-bit cingg? I tested on 32bit as usual, but strange decoding of theora video happens for me on aarch64/termux with dynamic ffmpeg 8.0.1 too. But I can't see misaligned render there .. only initial decoding bug. tvbars should be exactly same you send me: === sha256sum /home/ftp/incoming/tvbars.ogg f9bdf8471cc7c122348e5d6da8071d499511b1fae6280826f5d2646ddf05e7b5 /home/ftp/incoming/tvbars.ogg ====
