AVCodecContex returns zero for width and height in android
17 février 2023, par WhoamiNot sure what was my mistake in the below code. I m trying with ffmpeg 0.11 and SDL2.0 in android.



QUESTION :
Why Width and Height of the CodecContext gives me always zero ?..



int main(int argc, char *argv[])
{

 int flags;
 flags = SDL_INIT_VIDEO | SDL_INIT_TIMER;

 if (SDL_Init (flags)) {
 LOGD ("Could not intialize Video for SDL: %s \n", SDL_GetError());
 }
 else 
 LOGD (" SUCCESS: SDL_Init ");

 // ffmpeg Register all services..
 ffmpeg_register_all (); 


 pFrame = avcodec_alloc_frame ();
 context = avformat_alloc_context();

 err = avformat_open_input (&context, "rtsp:ip:port", NULL, NULL);
 if ( err < 0) {
 __android_log_print(ANDROID_LOG_DEBUG, "ffmpegguard", "Unable to open rtsp... ");

 return -1;
 }

 for (i = 0; i < context->nb_streams; i++)
 { 
 // Find the Decoder.
 codec = avcodec_find_decoder(context->streams[i]->codec->codec_id);
 if (codec->type == AVMEDIA_TYPE_VIDEO ) {
 __android_log_print(ANDROID_LOG_DEBUG, "ffmpegguard", "Found Video Streaming.. ");
 videoStreamIndex = i;

 }
 }

 // Play RTSP
 av_read_play(context);

 // Get Codec Context.
 pCodecCtx = context->streams[videoStreamIndex]->codec;
 if ( pCodecCtx == NULL )
 __android_log_print(ANDROID_LOG_DEBUG, "ffmpegguard", "CodecCtx is NULL>>> ");
 else
 __android_log_print(ANDROID_LOG_DEBUG, "ffmpegguard", "CodecCtx is <<<ok>>> ");


 //Find the Decoder.
 pCodec = avcodec_find_decoder (pCodecCtx->codec_id);
 avcodec_open2 (pCodecCtx, pCodec, NULL);


 int w = pCodecCtx->width; // Why me getting 0 ? 
 int h = pCodecCtx->height;

 window = SDL_CreateWindow ("Test ffmpeg",SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, w, h, SDL_WINDOW_SHOWN|SDL_WINDOW_ALLOW_HIGHDPI);
 // What this HIGHDPI Means ??

 if ( window != NULL ) 
 {
 LOGD (" WINDOW CREATED.. , create Renderer ..");
 renderer = SDL_CreateRenderer (window, -1, 0); 
 }
 else
 {
 LOGD (" Invalid SDL Window "); 
 }
__android_log_print(ANDROID_LOG_DEBUG, "ffmpegguard", "Width and Height of PCodeccCtx.. %d .. %d " , w, h); 
 return 0;
}
</ok>

If multiple channels, merge then take sample length from audio file and save it to s3
18 mai 2017, par khinesterI am using transloadit to extract the audio from a video file, which is then saved to S3.
This works great, but I wanted to know how to :-
check if the file has multiple channels and then squash it inot one as per https://transloadit.com/demos/audio-encoding/merging-multiple-audio-streams/ - do I need to check for this or do i default to use this robot ?
-
extract a small sample from the audio file - and save this as a separate file.
For example, I have a 2h audio file from which I want to take 5% of the length and save this as sample.mp3
In ffmpeg, i can cut :
ffmpeg -ss 0 -t 30 -i original.mp3 sample.mp3but I am unsure how to chain this workflow, here is what i have thus far :
const opts = {
params: {
notify_url: `${ process.env.SELF }/services/trans/${ jwToken }`,
steps: {
import: {
robot: '/s3/import',
use: ':original',
bucket: process.env.S3_INGEST,
path: ingest.key,
key: process.env.AWS_ID,
secret: process.env.AWS_SECRET,
},
encode: {
robot: '/audio/encode',
use: 'import',
ffmpeg_stack: 'v2.2.3',
preset: 'aac',
ffmpeg: {
ab: '128k',
},
},
export: {
robot: '/s3/store',
use: 'encode',
bucket: s3Export,
path: `${ prefix }/${ token }.m4a`,
headers: {
'Content-Type': 'audio/mp4',
'x-amz-server-side-encryption': 'AES256',
},
key: process.env.AWS_ID,
secret: process.env.AWS_SECRET,
},
},
},
};in the docs, https://transloadit.com/docs/conversion-robots/ i can’t see how to do this ?
any advice is much appreciated.
