keepalive type and frequency in ffmpeg [on hold]
19 novembre 2013, par Jack SimthMy company has a bunch of IP cameras that we distribute - specifically Grandstream - and the manufacturer has changed their firmware. The normal keepalive that ffmpeg uses for the rtsp streams ( either ff_rtsp_send_cmd_async(s, "GET_PARAMETER", rt->control_uri, NULL) ; or ff_rtsp_send_cmd_async(s, "OPTIONS", "*", NULL) ; both in in libavformat/rtspdec.c) is no longer working, for two reasons :
1) The new Grandstream firmware is now checking for a receiver report to determine whether or not the program reading the stream is live, not just anything.
2) The new Grandstream firmware requires that the receiver report to keep the connection alive happen at least once every 25 seconds, and on the audio stream it is currently only happening about every 30 seconds or so (video is getting it every 7 seconds or so).
So after about a minute with ffmpeg connected, the camera stops sending the audio stream, the audio stream on ffmpeg reads end-of-file, and then ffmpeg shuts everything down.
As I can't change the firmware, I'm trying to dig through the ffmpeg code to make it send the appropriate receiver report for the keep alive... but I am getting nowhere. I've added a little snippet of code into the receiver reports so I know when they're running when I call ffmpeg on debug, but... well, it's not going well.
Test command :
ffmpeg -loglevel debug -i rtsp ://admin:admin@192.168.4.3:554/0 -acodec libmp3lame -ar 22050 -vcodec copy -y -f flv /dev/null &> test.txtTest output :

Unable to transcode video using ffmpeg transcoder
28 octobre 2014, par user1843970This question may be asked in different forums but still answer is not discovered yet.
I am trying to play *.flv using Video Module and FFMPEG Converter.
Whenever I upload any flv Video , I get the following message :-PHPVideoToolkit error : Execute error. It was not possible to encode "C :\xampp\htdocs\Resonance\sites\default\files\videos\original\barsandtone_3.flv" as FFmpeg returned an error. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".
Installed Modules are :-
Video - 7.x-2.9
Video.js - 7.x-2.3 - Version : 4.0.3
Video transcoder : FFmpeg / avconv : git : c2dd5a1
JW Player
All above are installed correctly.
Configuration of Video Module :-
Inside Player Tab of Video(admin/config/media/video/players), following has been configured :-
A New FLV Preset has been created and added under Preset Tab of Video(admin/config/media/video/presets). Details are as Follows :-
Preset name :- FLV Preset
Video output extension :- FLV Flash Video
Video codec :- H 263/H263-1996,H263+/H0-º1998/H263 Version 2(Not sure about Video Codec)
FFmpeg video preset :- None
Video quality :-None
Video speed :- None
Dimensions :- 640 X 360
Aspect mode :- Preserve Aspect Ratio
When I am uploading the video from content type then it extract the thumbnail as follows :-
After saving the video it shows the following Mesage :-
My gut feeling is that I am setting up wrong preset but I am not able to solve this problem out. Please help me as I am very close to my completion of project which would have been waste without solving the problem.
Updated :-
The Console message is as follows :-

Re-creating/matching ffmpeg settings
8 novembre 2013, par Pete HelgrenI have an MP4 file that plays pretty much on every browser using either HTML5 or flash fallback (using mediaelement.js). I also have a series of additional video files that I would like to have "match" the one file that does play consistently but I haven't been able to match the ffmpeg settings so it produces a like file. I used ffprobe and got the following results on the file that plays successfully :

[libx264 @ 0000000000358160] kb/s:300.33The one problem with the incantation above is that on iPad's and iPhones and some Android tablets all you hear is the audio with no video. But the file listed above (contents of the ffprobe) does not have that problem, it WILL play on an iPad, iPhone, Android tablet. I researched causes for "audio, no video" and the recommendations were all over the deck. But, the file listed in the ffprobe DOES play, so if I can match those settings described by the ffprobe for all of the other videos, they should play consistently as well. My challenge is to match the ffprobe settings using ffmpeg and there doesn't seem to be a 1 to 1 match between what I see in ffprobe and the corresponding settings in ffmpeg (a nice utility would be to have ffprobe output the ffmpeg settings that could be used to create a file of similar format).
I walked through the ffprobe documentation but couldn't find anything that would produce a format that could be used as input to ffmpeg. Suggestions ?
