Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...

Pas question de marché, de cloud etc...
10 avril 2011Le vocabulaire utilisé sur ce site essaie d’éviter toute référence à la mode qui fleurit allègrement

Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

The ffmpeg webm_dash_manifest demuxer fails with webvtt subtitles
30 janvier 2020, par HyldreanI am trying to create a DASH manifest using ffmpeg and I encounter some difficulties with the subtitles. I get the error
[webm_dash_manifest @ 0x55e19db48180] EBML header parsing failed
[webm_dash_manifest @ 0x55e19db48180] Failed to read file headers
subtitles.vtt: Operation not permittedThe subtitles are encoded in the plain text webvtt format. I first assume that the EBML header are missing because the subtitles were not contained in a webm container. I then tried to create a webm file containing only the subtitles. It appears impossible.
I think the problem comes from the webm_dash_manifest demuxer. It seeks metadata in a file with no metadata. However neither Google nor Stack Overflow give me an answer.
The command I used :
ffmpeg \
-f webm_dash_manifest -i video.webm \
-f webm_dash_manifest -i audio.webm \
-f webm_dash_manifest -i subtitles.vtt \
-map 0 -map 1 -map 2 \
-c copy \
-f webm_dash_manifest \
-adaptation_sets "id=0,streams=0 id=1,streams=1 id=2,stream=2" \
minimal.mpdand the ffmpeg output :

is harmless according to this post.The subtitles have been extracted with ffmpeg :
ffmpeg -i "Cloud Atlas.mkv" -map 0:6 -t 00:05:00 -c:s webvtt -dash 1 subtitles.vtt
Thank you for reading my long post, I have no idea what to do next.
EDIT : The WebM Project website says : ’Initial WebM release does not support subtitles’. Has someone heard of a new release ? Or a convenient way to create DASH manifest with subtitles ?

CRF/CQP is incompatible with 2pass. FFmpeg error
22 juillet 2020, par user12129980This is my command :



..\ffmpeg -y -i "D:\FFMPEG\ffmpeg-20200129-de1b2aa-win64-static\bin\test\aa_start_with_BAGAN.mp4" -c:v libx264 -preset ultrafast -maxrate 3000k -bufsize 6000k -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 -an -pass 1 -f mp4 NUL && ..\ffmpeg -i "D:\FFMPEG\ffmpeg-20200129-de1b2aa-win64-static\bin\test\aa_start_with_BAGAN.mp4" -c:v libx264 -s 1280x720 -preset ultrafast -maxrate 500k -bufsize 1000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 -an -pass 2 aa_start_with_BAGAN.mp4_ultrafast_500.mp4




in the output I get
CRF/CQP is incompatible with 2pass
, but I didnt use the cfr/-q option in the command at all, why do I get this error ?
Add the full metadata of FFMpeg maybe someone can help me with this ?
(-g 50 because the default fps is 25 base on the documentation)

Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (NUL) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
