Which decoder does ffmpeg actually use ? [closed]
8 décembre 2024, par LTRHow can I get ffmpeg to show exactly which decoder it uses ?


Example 1


In this example, I request Intel QuickSync decoding. However, QuickSync is not available because it's running on an AMD CPU. ffmpeg seems to fall back to CPU decoding, but doesn't say anything about that :


> ffmpeg -hwaccel qsv -i "file.mp4" -f null -
...
(nothing in the output refers to choice of decoder)


Example 2


In this example, we request "auto" hardware acceleration.


> ffmpeg -hwaccel auto -i "file.mp4" -f null -
...
[h264 @ 000001ed37d7a040] Using auto hwaccel type dxva2 with new default device.


Ffmpeg says that it uses the DXVA2 API with the default device. This is better than nothing, but it would be helpful if it said the name of the device chosen.


How can I instruct ffmpeg to always output this information ? I tried "-v verbose" but did not find anything in the output regarding the choice of decoder.

ismindex : Use the individual stream duration instead of the global one
3 octobre 2013, par Martin Storsjöismindex : Use the individual stream duration instead of the global one
The stream duration is used for calculating the duration of the
last fragment easily without manually parsing anything else than
the mfra/tfra atoms. When the global file duration was used
previously, the duration of the last fragment could end up wrong
if the streams weren’t equally long.Signed-off-by : Martin Storsjö <martin@martin.st>
