De l’upload à la vidéo finale [version standalone]
31 janvier 2010, parLe chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.

Using FFMPEG : How to do a Scene Change Detection ? with timecode ?
30 mai, par MozartBased on this article it seems that it is possible to use FFMPEG to detect scene change in videos :
http://www.luckydinosaur.com/u/ffmpeg-scene-change-detector



Now I have a video that displays a book text and when the text (word or sentence) is spoken it gets highlighted. 
Something like this audio book : https://youtu.be/lA7L6ZNVKjc



I need to know the timestamp when the text gets highlighted (hence scene change), this will allow me to add timestamp tags on my youtube video, so it becomes easier for listeners to navigate through the audiobook.



What is the magic command line that would do this ?



Thank you very much !

avutil/mips : refactor msa load and store macros.
17 juillet 2019, par Shiyou Yinavutil/mips : refactor msa load and store macros.
Replace STnxm_UB and LDnxm_SH with new macros ST_H/W/D1/2/4/8.
The old macros are difficult to use because they don't follow the same parameter passing rules.
Changing details as following :
1. remove LD4x4_SH.
2. replace ST2x4_UB with ST_H4.
3. replace ST4x2_UB with ST_W2.
4. replace ST4x4_UB with ST_W4.
5. replace ST4x8_UB with ST_W8.
6. replace ST6x4_UB with ST_W2 and ST_H2.
7. replace ST8x1_UB with ST_D1.
8. replace ST8x2_UB with ST_D2.
9. replace ST8x4_UB with ST_D4.
10. replace ST8x8_UB with ST_D8.
11. replace ST12x4_UB with ST_D4 and ST_W4.Examples of new macro : ST_H4(in, idx0, idx1, idx2, idx3, pdst, stride)
ST_H4 store four half-word elements in vector 'in' to pdst with stride.
About the macro name :
1) 'ST' means store operation.
2) 'H/W/D' means type of vector element is 'half-word/word/double-word'.
3) Number '1/2/4/8' means how many elements will be stored.
About the macro parameter :
1) 'in0, in1...' 128-bits vector.
2) 'idx0, idx1...' elements index.
3) 'pdst' destination pointer to store to
4) 'stride' stride of each store operation.Signed-off-by : Michael Niedermayer <michael@niedermayer.cc>
