Hi,
I am facing error while building libraries.
I have NOT applied any of my customizations in Android_configuration.mk and proceeded for build with "mm" command.

BUILD:
executed the command "mm" in folder ffmpeg-android.

ERROR:
The source files are built for libraries , but finally i am facing the below error -

ffmpeg for android ...usage in android command line

venkatesh babu — Mon, 26 Oct 2015 06:59:52 -0000

Hi,

I am able to sucessfully build ffmpeg for android in my android source root dir/external.

I want to know how to install the generated ffmpeg executables on any android phone and use it in the command line.

Example in command line as

ffmpeg -version
or
ffmpeg -thread_queue_size 512 -analyzeduration 0 -probesize 32 -f v4l2 -s 640x480 -r 30 -i /dev/video0 -thread_queue_size 512 -f alsa -ac 2 -i hw:1 -fflags nobuffer -g 0 http://localhost:8091/feed1.ffm

ffmpeg http live streaming support -- how to use the api in segment.c

derekzhuo — Wed, 17 Jun 2015 06:11:53 -0000

yes, i get it work now, but here is another problem, in the latest version of ffmpeg4android, the support for hls are limited, i can only see 4 options:
static const AVOption options[] = {
{"start_number", "set first number in the sequence", OFFSET(sequence),AV_OPT_TYPE_INT64, {.i64 = 0}, 0, INT64_MAX, E},
{"hls_time", "set segment length in seconds", OFFSET(time), AV_OPT_TYPE_FLOAT, {.dbl = 2}, 0, FLT_MAX, E},
{"hls_list_size", "set maximum number of playlist entries", OFFSET(size), AV_OPT_TYPE_INT, {.i64 = 5}, 0, INT_MAX, E},
{"hls_wrap", "set number after which the index wraps", OFFSET(wrap), AV_OPT_TYPE_INT, {.i64 = 0}, 0, INT_MAX, E},
{ NULL },
};

which means i can not delete old ts file.

do you have any higher version of ffmpeg4android?

thanks!

thanks, i notice that the cmd line tool could used to segment stream, but i need to implement one as a .so by myself, which could be invoked by application in java. so i need to figure out how exactly the muxer is initilized and get invoked.

FFmpeg contains HLS muxer, it may be easily used from command line. It will cut Your file into segments of the specified length, and make M3U8 playlists for VOD or live streaming (e.g. from live source, like camera). For muxer names and available options check the source code avformat/hlsenc.*

If You are just trying to remux some stream, and do not try to calculate PTS/DTS values, then probably stream contains values which FFmpeg consider as invalid.

Guys, I am working on a hls segmenter on android which doesn't contain the tool, so i have to finish one by myself, i tried m3u8-segmenter of johnf on github, but it does not work fine, and then i saw there is a segment.c in ffmpeg project, but it does not contain something like segment.h, i just do not know how to kick off, could some one tell me how to use the APIs in file segment.c.

Thanks.

Thanks, but it doesn't always happen, some input stream work fine, while some not, is there any chance that the input stream carry problems?

I guess You are setting invalid values to the PTS fields of frames You want to mux. Find proper muxing example (I believe there is one in FFmpeg folder doc), and check how it is done. You need to take care of time base, and use it to calculate proper PTS values from Your frame rate, in a given time base (for TS it is always 1/90000).
