avformat/mxfdec : disallow generic seek search
26 août 2024, par Marton Balintavformat/mxfdec : disallow generic seek search
If the demuxer does not provide per-stream indexes, the generic seek search can
attempt to read the whole media file from the beginning when seeking. For large
MXF files this can cause huge lockups for a seek after the last timestamp,
which will eventually fail. So let's disable the generic seek for mxf, the
demuxer's own seek code should handle seeking just fine.Signed-off-by : Marton Balint <cus@passwd.hu>

How to make ffmpeg segment filename have the time created
14 novembre 2014, par user1500191Im using ffmpeg to segment a video stream and i would like ffmpeg to name the segment files with a created date/timestamp.
Is this possible ?
Currently, ffmpeg overwrites the file’s created-time with it’s modified time.
Lets say i have segments of 30sec video each :
0000.flv, 0001.flv, 0002.flv etc
When i do ffprobe of each video segment i "correctly get" 30 seconds ! this is nice
HOWEVER
Each file has a "last modified time"/"created time" that i can read—
WHen i subract 0001.flv (modified time) - 0000.flv (modified time) i get a result of 29seconds.
The video duration is 30seconds, but the time between either date created or last modified is 29 seconds !
This is a huge problem— can someone please help.
NOTE : This problem is not present when segmenting to mp4 — it is only present when segmenting to FLV
I actually have same ffmpeg commandline parameters, just changing the format from mp4 to flv and the flv has segmentation has the behavior described above.
Please help.
Thanks
