record video and audio on android

[ares89]

Happy new Year!Happy 2014!

I want record video from rtsp which transforms H264.

so I add the function "Add new API to libvlc to record the current media to either an application-specified file or a file " from https://patches.videolan.org/patch/606/

it works, but the function seems missing the audio while the video has been recorded.

I don't know what to do the record the audio with video.

helps! thank you!

Maybe you don't have the audio encoder necessary for it. Check the logs.

thanks. The log is as below, i cannot find the bug...

this logs start from the start of recording,stop at when the file is saved.

thank you!

[Jean-Baptiste Kempf]

you are missing a lot of muxers.

[ares89]

you are missing a lot of muxers.

I am sorry to hear that... and I am happy for your answering.
what muxer i am missing? and how can i add it ?

[jason_lee]

hi,friend, I am also doing the same thing. I just want to record the video. I added this function followed the https://patches.videolan.org/patch/606/, but it seems don't work. Could you tell me what to do after following the https://patches.videolan.org/patch/606/?
Thanks in advance!

[ares89]

you are missing a lot of muxers.

I find the reason g726 cannot be record is that Muxer cannot add the G726 stream.
the vlc uses avi muxer defautly, and in the file avi.c, the avi muxer not deal with VLC_CODEC_ADPCM_G726.
so i add below in avi.c, my G726 is 32bit.

Code: Select all

case VLC_CODEC_ADPCM_G726: p_wf->wFormatTag = WAVE_FORMAT_G726; p_wf->wBitsPerSample = 4; p_wf->nAvgBytesPerSec = (p_wf->wBitsPerSample/8) * p_wf->nSamplesPerSec * p_wf->nChannels; break;

so the stream can be record now. but the avi file recorded cannot be play.
the vlc player gives the error below:

Code: Select all

now the problem is vlc don't have g726 decoder, what can i do now? thanks for your help!

[Jean-Baptiste Kempf]

code a decoder or link to one.
