18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

The Video, Audio and Subtitle work perfectly If I try to open this stream in VLC n Ubuntu.
so far, so good

Unsupported codec with id 94215 for input stream 10




So I decide to use FFMPEG to stream to UDP, and filter out unwanted SUB's



Here is FFMPEG cmd



ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2048 \
 -i "http://192.168.1.44:8001/1:0:1:1F8:1B:2C0:E080000:0:0:0:" \
 -map 0:0 -vcodec copy \
 -map 0:1 -acodec copy \
 -map 0:2 -map 0:6 -scodec copy \
 -f mpegts udp://239.0.10.3:40000?pkt_size=1316




And the output is :



Output #0, mpegts, to 'udp://239.0.10.3:40000?pkt_size=1316':
 Metadata:
 encoder : Lavf57.63.100
 Stream #0:0: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, top first), 720x576 [SAR 64:45 DAR 16:9], q=2-31, 25 fps, 25 tbr, 90k tbn, 90k tbc
 Stream #0:1: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 256 kb/s
 Stream #0:2(srp): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)
 Stream #0:3(hun): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)
Stream mapping:
 Stream #0:0 -> #0:0 (copy)
 Stream #0:1 -> #0:1 (copy)
 Stream #0:2 -> #0:2 (copy)
 Stream #0:6 -> #0:3 (copy)




And the resulting stream is DISASTER ... audio is choppy, video fall apart etc etc



If I try same thing WITHOUT sub's (map 2 and 6) the video and audio is crystal clear and stream work well



But I need this two sub's.



To narrow down the problem, if I try to capture incoming stream into file :



ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2048 \
-i "http://192.168.1.44:8001/1:0:1:1F8:1B:2C0:E080000:0:0:0:" \
-map 0:0 -map 0:1 -map 0:2 -map 0:6 \
-codec copy \
-y -f mpegts /tmp/tst.ts




The resulting file is playable, sound OK, video OK, subtitles OK.



Looks like problem is with OUTPUT to UDP ???



Any solution for this ?

How to handle differing .mp4 file types from different sources ?
10 octobre 2017, par Dave502619If I take a .mp4 recorded on my mobile (Samsung S5) and pass it through FFmpeg with the below command, the output file (
fileX.avi
) is a greyscale bitmap uncompressed video file.-
The offset values in
fileX.avi
(output from FFmpeg) to allow me to locate the video frame data are always 5680 bytes for the file header. -
And 62 bytes for the inter frame header.
-
The data is uncompressed RGB24 so i can easily calculate the size of a video frame from height x width x 3.
So my C# application can access the video frames in
fileX.avi
always at these above offsets.
(This works great).My FFmpeg Command is :
ffmpeg.exe -i source.mp4 -b 1150 -r 20.97 -g 120 -an -vf format=gray -f rawvideo -pixfmt gray -s 384x216 -vcodec rawvideo -y fileX.avi
However... I recently took an .mp4 file from a different source (produced by Power Director 14 instead of direct from my mobile phone) and used this as the input
source.mp4
. But now the structure offileX.avi
differs as the offset values of 5680 + 62 bytes from the start infileX.avi
do not land me at the start of the video data frames.There seems to be different file formats for .mp4 - and obviously if there are my crude offset approach will not work for them all. I suspected at the time I wrote the code my method was all too easy a solution !
So can anyone advise on the approach I should take now ? Should I check the original .mp4 or the output file (
fileX.avi
) to determine a "file type" to which I can determine the different offsets ?At the very least I need to be able to identify the "type" of .mp4 file that works so I can declare the type that will work with my software.
