Video length missing in FLV converted by ffmpeg-php
19 janvier 2013, par AndrewI'm converting MP4 videos to FLV using ffmpeg-php on my CentOS server (without intervention from flvtool2 because it's not installed).
The FLV videos are created, but no player is capable of retrieving the video duration, this creates serious issues when trying to seek the video. I'm using the player created by Moyea's Flash Video MX Pro, but the problem also happens with other FLV players as well, so I'm sure that ffmpeg-php is not createing the FLV with the proper length data.
My MP4 videos are compatible because ffmpeg-php CAN get the video length properly from then, yet it does not apply that length information into the FLV file. I assume flvtool2 is ONLY to retrieve meta-data and has nothing to do with the output FLV video length, let me know if this is correct.
This command I use for conversion :
$command = "ffmpeg -i myvideo.mp4 -ar 22050 -ab 64k -f flv -s 320x240 -y myvideo.flv";
$result = @shell_exec($command);This is my ffmpeg-php version :

FFMPEG Segmenting skips when m3u8 changes file
25 septembre 2012, par user792164I am attempting to segment a large video file in to segments. When streamed (even locally) by opening the m3u8 file it will jump forward in time by some period of time less than 1 second.
The following commands are executed :
First mp4 —> ts :
ffmpeg -i input_file.mp4 -bsf:v h264_mp4toannexb -acodec libfaac -vcodec libx264 -f mpegts -threads 0 output.ts
Then I split using :
ffmpeg -i output.ts -vcodec copy -acodec copy -map 0 -f segment -segment_time 30 -segment_list output.m3u8 -segment_list_type m3u8 -segment_format mpegts output%03d.ts
Note : Changing segment time has no effect on issue.

Is it possible to remove this jump, if so, what encoding parameters or incorrect assumptions have I made ? Thanks.

Evolution #2881 (Fermé) : Table spip_meta et plugin champs extra
3 mai 2013, par cedric -je pense que le bug concerne le plugin Champs extra qui devrait gérer ça, soit avec une table meta dédiée, soit en modifiant la taille des champs SQL. Mais il faut avoir conscience que charger toutes ces données à chaque hit dans les meta est dispendieux, alors qu’on en a besoin que lors du calcul/compilation d’une page, et dans l’espace privé.
Cela plaide donc pour une table meta dédiée au plugin.
Je ferme car étendre les champs SQL de spip_meta par defaut conduira a augmenter le volume de données stockées dans spip_meta et poser des pb de perf (données chargées à chaque hit). Il ne faut donc pas faire de stockage lourd dans spip_meta.
