Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.

FFMPEG enocde flv with alpha channel
25 octobre 2013, par treeI'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either
- find a codec that is supported
- find one that actually maintains the alpha
Does anyone know how to set that up ?
Thanks,
ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv
here is the report...

first is a warning during execution
deprecated pixel format used, make sure you did set range correctly
The second is the video do not work correctly in VLC (video is "black") but it work in wmp...Then I add an empty audio track :
ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"
After that I concat this video to others using complex filter .
When I concat my videos I have this message :[output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.
And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
perhaps it is not related
I don't know ...Here my concat command and execution log

Converting DVD image with subtitles to MKV using avconv
16 janvier 2016, par Carlos Eugenio Thompson PinzónThis is the procedure I know to convert a DVD image to another videoformat (v.g. MP4) :
- concatenate the
VTS_01_
n.VOB
files insideVIDEO_TS
folder (for n >= 0) into a single VOB file. - use
avconv
orffmpeg
in order to convert that VOB into another format.
So far so good, however now I want to convert the DVD image with the subtitles. As far as I know the MKV format supports subtitles, so it seems an obvious choice. Alternatively I might use any other format with hard subtitles (subtitles as part of the video image).
However, the subtitle encoding in the DVD image is
dvdsub
and I get the following errorOnly SUBTITLE_ASS type supported.
Subtitle encoding failedHowever, when running
avconv -codecs
I get :...
DES dvdsub DVD subtitles
...And the
-c:s copy
switch, while it prevents the command to fail, it does not seem to produce a subtitle that the player can understand.So, how can I create
ass
subtitles fromdvdsub
usingavconv
?My VOB file has eight subtitle channels and two audio channels. The Ubuntu video app does not show any subtitles, and only the first audio channel seems to be working, do the DVD image might be broken.
Another file, for a double-layer DVD, displays the Subtitle encoding error, however when using the
-c:s copy
switch it further displays :Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
av_interleaved_write_frame(): Invalid argumentThank you in advance for any ideas on how to solve these problems.
(I am using Ubuntu where
ffmpeg
is an alias foravconv
. I know it is possible to install the real ffmpeg but so far I have not done so.)
