Can I set rotation field for a video stream with FFmpeg ?
19 février 2016, par Alexander KulyakhtinI have a video file. I open it with MediaInfo utility and I can see a video stream in this file having attribute Rotation 90 (along with other attributes such as CodecID, bitrate etc).
Now I have another video file which does not have that attribute Rotation 90, it does not have the Rotation attribute at all.
Can I use ffmpeg.exe so that it produces output file with Rotation 90 attribute added and with no other changes ? I don’t really want to do any transform, just want to set the Rotation attribute.
I’ve tried the
-metadata
option to no avail. -
lavu/stereo3d : change the horizontal FOV field to a rational
23 juin 2024, par Lynnelavu/stereo3d : change the horizontal FOV field to a rational
This avoids hardcoding any implementation-specific limitiations as
part of the API, and allows for future expandability.This also allows API users to more conveniently convert the
values into floats without hardcoding specific conversion constants.The API was committed a few days ago, so changing this field now
is within the realms of acceptable.- [DH] fftools/ffprobe.c

lavc : use a separate field for exporting audio encoder padding
23 août 2014, par Anton Khirnovlavc : use a separate field for exporting audio encoder padding
Currently, the amount of padding inserted at the beginning by some audio
encoders, is exported through AVCodecContext.delay. Howeverthe term ’delay’ is heavily overloaded and can have multiple different
meanings even in the case of audio encoding.this field has entirely different meanings, depending on whether the
codec context is used for encoding or decoding (and has yet another
different meaning for video), preventing generic handling of the codec
context.Therefore, add a new field — AVCodecContext.initial_padding. It could
conceivably be used for decoding as well at a later point.- [DBH] doc/APIchanges
