ffmpeg says : "option framerate not found"
16 juillet 2013, par JasonGood afternoon.
I've been trying to use ffmpeg to split a .mpeg into a sequence of .jpeg images. Please note that this is the inverse problem of the one specified here, but the problem I'm facing is not the same as the problem the author of that thread is facing.
Specifically, I have tried all the following mpeg codecs available in my ffmpeg installation :
DEV D ffv1 FFmpeg video codec #1
DEVSD ffvhuff Huffyuv FFmpeg variant
DEVSDT mpeg1video MPEG-1 video
D V DT mpeg1video_vdpau MPEG-1 video (VDPAU acceleration)
D V D mpeg2_crystalhd MPEG-2 Video (CrystalHD acceleration)
DEVSDT mpeg2video MPEG-2 video
DEVSDT mpeg4 MPEG-4 part 2
D V D mpeg4_crystalhd MPEG-4 Part 2 (CrystalHD acceleration)
D V DT mpeg4_vdpau MPEG-4 part 2 (VDPAU)
D VSDT mpegvideo MPEG-1 video
D V DT mpegvideo_vdpau MPEG-1/2 video (VDPAU acceleration)
D VSDT mpegvideo_xvmc MPEG-1/2 video XvMC (X-Video Motion Compensation)
DEVSD msmpeg4 MPEG-4 part 2 Microsoft variant version 3
D V D msmpeg4_crystalhd MPEG-4 Part 2 Microsoft variant version 3 (CrystalHD acceleration)
D VSD msmpeg4v1 MPEG-4 part 2 Microsoft variant version 1
DEVSD msmpeg4v2 MPEG-4 part 2 Microsoft variant version 2I've tried supplying ffmpeg with all different codecs to try to split an input .mpeg video file with 2548 frames into 2548 .jpegs, by using the -vcodec option :
ffmpeg -r 2548 -i frames.mpeg frames_%06d.jpg -vcodec $codec
where
$codec
is any codec among the ones listed above, e.g.ffv1
,mpeg4
, etc. However, all my efforts result in the following error :[NULL @ 0x1948f20] Value 4707126720094797824.000000 for parameter 'probesize' out of range

Option framerate not found.Which is weird, because I've actually specified the frame rate parameter through the -r switch. I googled a bit and it appears that this error was mentioned approximately a year and a half ago on the ffmpeg bug tracker but that information makes little sense to me because it's relevant to the devs. Curiously, if I interchange the position of the parameters and put -r after -i or even after -vcodec, the error message changes to :

WebVTT Audio Descriptions for Elephants Dream
10 mars 2015, par silviaWhen I set out to improve accessibility on the Web and we started developing WebSRT – later to be renamed to WebVTT – I needed an example video to demonstrate captions / subtitles, audio descriptions, transcripts, navigation markers and sign language.
I needed a freely available video with spoken text that either already had such data available or that I could create it for. Naturally I chose “Elephants Dream” by the Orange Open Movie Project , because it was created under the Creative Commons Attribution 2.5 license.
As it turned out, the Blender Foundation had already created a collection of SRT files that would represent the English original as well as the translated languages. I was able to reuse them by merely adding a WEBVTT header.
Then there was a need for a textual audio description. I read up on the plot online and finally wrote up a time-alignd audio description. I’m hereby making that file available under the Create Commons Attribution 4.0 license. I’ve added a few lines to the medadata headers so it doesn’t confuse players. Feel free to reuse at will – I know there are others out there that have a similar need to demonstrate accessibility features.
The post WebVTT Audio Descriptions for Elephants Dream first appeared on ginger’s thoughts.

Linking FFMPEG library for Android
24 février 2016, par HARSHA HNCan you be requested to look into this issue ? I am trying to integrate our custom application into Teaonly’s Streaming application. But, this app compresses using H264 compression (which is required for our app). But, I have been unable to integrate FFMPEG into our solution.
Can somebody be requested to let us know the steps in simple terms ? (I am new to NDK Android) [Experts are requested to be kind to us]
Thanks for your time and consideration.
(By the way, the ffmpeg has been built and the following links are sounding too complicated :
