Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Using ffmpeg To Convert wav file to g729 file
30 novembre 2023, par UserProgI am using
ffmpeg
in my Windows laptop to convert.wav
to.g729
format. I have spent some times on the documentation, tutorials, and some threads with no success till now.


Below is my
ffmpeg
version details :


ffmpeg version N-89674-g57d0c24132 Copyright (c) 2000-2018 the FFmpeg developers

libpostproc 55. 0.100 / 55. 0.100



I have tried
ffmpeg -i testA.wav -c:a libavformat -f g.729 output.g729
and ended up with error saying[NULL @ 0000022aa639dd80] Requested output format 'g.729' is not a suitable output format
output.g729: Invalid argument
.


I did try some different format names with no success still.



Appreciate some guidance on this. Thanks.

How to get rid of errors "jitter buffer full" in ffmpeg ?
31 janvier 2021, par jidckiiHow to get rid of errors
jitter buffer full
?

I use ffmpeg from one of the latest snapshots.

ffmpeg version N-90078-gf611fef Copyright (c) 2000-2018 the FFmpeg developers



The problem is that from the camera on rtsp there is such a stream :

http://ibb.co/fmckCc

It is not possible to fix this from the camera side.


I accept it like this :



ffmpeg \
-strict experimental \
-fflags + genpts \
-fflags + latm \
-seek2any 1 \
-avoid_negative_ts + make_zero \
-max_delay 5000000 \
-rtsp_transport udp \
-i rtsp: // admin: @ 192.168.87.21: 554/0? .sdp \
-map 0 \
-r 15 \
-c: v copy \
-an \
-f mpegts udp: //239.0.0.1: 1234? ttl = 1? pkt_size = 1316




I later start to get errors from time to time



[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 2 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 4 packets




because of this the picture crumbles.



I increased the udp buffer in the linux kernel settings :



net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.udp_mem = 8388608 12582912 16777216
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 65536 8388608




It did not solve my problem.

Tell me, how can you deal with such errors ?

Discard data stream from container using ffmpeg
10 décembre 2020, par A.BeI am trying to get rid of a data (subtitle) stream within a Mp4 container, using ffmpeg.



Here's the screenshot from ffprobe :

I tried :



ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4




Data track still there, just moved from stream 0 to stream 2



I tried also :



ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4




Same result, track still there, just jumped to stream 0:2 no luck.



Any hint ?
Thanks in advance
