Change file format from flv to anything android will play
19 octobre 2011, par BilthonI need to take this file which encoded is in h264 but in a flv container and just put it in a mp4, 3gp or whatever file format the android MediaPlayer will understand.
I want to do this natively. As I will not be decoding nor encoding anything I think I will not be wasting a lot of power (am I wrong?)
I followed the instructions from here http://www.roman10.net/?p=394 and could sucessfully compile and use ffmpeg and use it with mp4 and 3gp files.
But when it comes to flv files it fails. I understand there is no format definition for flv files in that specific port of ffmpeg for android.
There is no libavformat/flv.h header file for instance.
Maybe that's why this works:
extern AVInputFormat ff_mov_demuxer;
av_register_input_format(&ff_mov_demuxer);While this fails:
extern AVInputFormat ff_flv_demuxer; av_register_input_format(&ff_flv_demuxer);Question is, is there a light at the end of the tunnel? has someone done something similar? is it useful? I mean, I can always just throw the flv media file into a flash player and voila.. the thing is that this would be a parcial solution, as it will not work for all those folks running slower devices that can't yet run Flash.

PS. Just in case. Here's some info about the file I'm talking about:

PHP exec not working properly
18 octobre 2011, par asdI'm trying to run ffmpeg in my WAMP server with the exec command. Though I have set in the .htaccess file "php_value safe_mode off" and apache allow the override, the exec is still not working properly. if I try to execute
<? php exec("mkdir aaa"); ?>it works, but when I do something like
exec("ffmpeg.exe -y -i D:\Documents\Video.wmv -f mp4 D:\Documents\Video.mp4 -y");it doesn't do nothing. This works fine is prompted in the command line, but for some reason it doesn't when I try to execute it from the server. Do you have any ideas?

How to encode and segment at the same time ?
18 octobre 2011, par lvreinyI want to implement HTTP streaming server, which is similar to this (http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/) But, instead of segment the video file after it is completely converted by ffmpeg, I want to do encoding and segmenting at the same time (something like if the output stream from the encoder is sent to the segmenter immediately).
Thanks

Dumping and playing h264 bytestream from RTSP webcam
18 octobre 2011, par thekMy goal is to connect (rtsp) to camera, get h264 stream from rtp packages, save it as a bytestream to file and be able to play it (with ffplay or vlc). The only problem is that my result stream gives me errors (and a nice gray rectangle, sometimes with something moving - like only P frames are decoded) while playing.
Here is my DESCRIBE response from rtsp server (ip replaced with ):
10:04:18.387 [New I/O client worker #1-1] INFO rtsp.WebcamClientResponseHandler - Sending DESCRIBE request: DESCRIBE rtsp://: /channel1 RTSP/1.0 -------status--------- 200 OK -------headers--------- CSeq : 2 Date : Wed, Jan 07 2009 19:05:09 GMT Content-Base : rtsp:// /channel1/ Content-Type : application/sdp Content-Length : 433 -------content--------- v=0 o=- 515949295799 1 IN IP4 s=Session streamed by stream i=1 t=0 0 a=tool:LIVE555 Streaming Media v2009.01.26 a=type:broadcast a=control:* a=range:npt=0- a=x-qt-text-nam:Session streamed by stream a=x-qt-text-inf:1 m=video 0 RTP/AVP 96 c=IN IP4 0.0.0.0 b=AS:128 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1;profile-level-id=420028;sprop-parameter-sets=Z0IAKOkCg/I=,aM44gA== a=control:tracks And server sends me RTP packages with non IDR frames and fragmented (type=28) IDR frames. First ones are written to file, fragmented are unpacked. The result byte stream is:

NAL FRAMEN where NAL is (hex) 00 00 01 and SPS is (decoded Z0IAKOkCg/I= from sprop-parameter-sets): 67 42 00 28 e9 02 83 f2 and PPS is (decoded aM44gA==): 68 ce 38 80I found similar topic with same steps taken: how-to-process-raw-udp-packets-so-that-they-can-be-decoded-by-a-decoder-filter-i but I can't see what am I missing.
Could anyone give me some clue what may be wrong ?
This is a link to generated h264 file: a.h264
Below I'm attaching some more information from playing my stream.
Playing my video with ffplay -f h264 a.h264 gives me following output (and a gray rectangle):
