ffmpeg : failed to convert m3u8 to mp4

4 mars 2016, par MrSmile07

I want to convert a .m3u8 file into .mp4, for that I am using ffmpeg.
The only Thing that disturbs is, that one file work with the Command and the other not.

Here the command :

ffmpeg -i http://91.250.77.10:8134/hls-vod/jp/523.mp4.m3u8 -acodec copy -vcodec copy  -y -loglevel info -f mp4 Namezurspeicherrung.mp4

that file works, but by the other file :

ffmpeg -i http://91.250.77.10:8134/hls-vod/mk/01.mp4.m3u8 -acodec copy -vcodec         copy  -y  -loglevel info -f mp4 Namezurspeicherrung2.mp4

doesn’t work.

OK : Here the Output from file 2 :

ffmpeg -i http://91.250.77.10:8134/hls-vod/mkmp4.m3u8 -acodec copy -vcodec copy  -y -loglevel info -f mp4 Wasichsiewirklichgernefragenwuerde.mp4

getting black and white image after encoding

16 mai 2012, par user1310596

I am trying to encode image using ffmpeg library and objective c. I am using following code but I am getting black and white image as the result. Is there something to do with pixel format(PIX_FMT) ? Please help me so that I can get colored image.

av_register_all();

avcodec_init();

avcodec_register_all();

avformat_alloc_context();



AVCodec *codec;

AVCodecContext *ctx= NULL;

int out_size, size, outbuf_size;

AVFrame *picture;

uint8_t *outbuf;

unsigned char *flvdata = malloc(sizeof(unsigned char) * 30);





outbuf_size = 200000;

outbuf = malloc(outbuf_size);





printf("Video encoding\n");



codec = avcodec_find_encoder(CODEC_ID_FLV1);

if (!codec) {

        fprintf(stderr, "codec not found\n");

        exit(1);

}



ctx= avcodec_alloc_context();

picture= avcodec_alloc_frame();





ctx->width = 320;

ctx->height = 240;

ctx->pix_fmt = PIX_FMT_YUV420P;



if (avcodec_open(ctx, codec) &lt; 0) {

        fprintf(stderr, "could not open codec\n");

        exit(1);

}



outbuf_size = 100000;

outbuf = malloc(outbuf_size);

AVFrame* outpic = avcodec_alloc_frame();

uint8_t* outbuffer = (uint8_t*)av_malloc(nbytes);



fflush(stdout);

CGImageRef newCgImage = [image CGImage];



CGDataProviderRef dataProvider = CGImageGetDataProvider(newCgImage);

CFDataRef bitmapData = CGDataProviderCopyData(dataProvider);

long dataLength = CFDataGetLength(bitmapData);



uint8_t *buffer = (uint8_t *)av_malloc(dataLength);

buffer = (uint8_t *)CFDataGetBytePtr(bitmapData);



for(int i = 0; i &lt; dataLength; i++)

{

        if((i + 1) % 16 == 1 &amp;&amp; i != 1)

                printf("\n");

        printf("%X\t",buffer[i]); // getting something different than the     actual hex value of the image

}







outpic -> pts = 0;        



avpicture_fill((AVPicture*)picture, buffer, PIX_FMT_RGB8, ctx->width, ctx->height);



avpicture_fill((AVPicture*)outpic, outbuffer, PIX_FMT_YUV420P, ctx->width, ctx->height);



struct SwsContext* fooContext = sws_getContext(ctx->width, ctx->height, 

                                                       PIX_FMT_RGB8, 

                                                       ctx->width, ctx->height, 

                                                       PIX_FMT_YUV420P, 

                                                       SWS_FAST_BILINEAR, NULL, NULL, NULL);



sws_scale(fooContext, picture->data, picture->linesize, 0, ctx->height, outpic->data, outpic->linesize);



printf("abcdefghijklmnop");

out_size = avcodec_encode_video(ctx, outbuf, outbuf_size, outpic);

printf("\n\n out_size %d   outbuf_size %d",out_size,outbuf_size);

Thanks in advance

Encoding video only FLV

25 mars 2012, par NadavRub

I am trying to generate a video only FLV file, I am using :

libx264 + ffmpeg
30 fps ( fixed )
playback is done using VLC 2.0.1 and flowplayer

When playing the FLV the frame-rate seems 1 frame per sec, following is the way I cfg ffmpeg :

AVOutputFormat* fmtOutput = av_oformat_next(0);

while((0 != fmtOutput) &amp;&amp; (0 != strcmp(fmtOutput->name, "flv")))

    fmtOutput = av_oformat_next(fmtOutput);

m_pFmtCtxOutput          = avformat_alloc_context();

m_pFmtCtxOutput->oformat = fmtOutput;



AVStream* pOutVideoStream= av_new_stream(m_pFmtCtxOutput, pInVideoStream->id);

AVCodec*  videoEncoder   = avcodec_find_encoder(CODEC_ID_H264);



pOutVideoStream->codec->width    = 640;

pOutVideoStream->codec->height   = 480;

pOutVideoStream->codec->level    = 30;

pOutVideoStream->codec->pix_fmt  = PIX_FMT_YUV420P;

pOutVideoStream->codec->bit_rate = 3000000;



pOutVideoStream->cur_dts         = 0;

pOutVideoStream->first_dts       = 0;

pOutVideoStream->index           = 0;

pOutVideoStream->avg_frame_rate  = (AVRational){ 30, 1 };

pOutVideoStream->time_base       =

pOutVideoStream->codec->time_base= (AVRational){ 1, 30000 };

pOutVideoStream->codec->gop_size = 30;

%% Some specific libx264 settings %%

m_dVideoStep                     = 1000;// packet dts/pts is incremented by this amount each frame



pOutVideoStream->codec->flags   |= CODEC_FLAG_GLOBAL_HEADER;

avcodec_open(pOutVideoStream->codec, videoEncoder);

The resulting file seems OK, with the exception of the playback frame-rate.
having in mind that :

pOutVideoStream->avg_frame_rate = (AVRational) 30, 1 ;
pOutVideoStream->time_base = (AVRational) 1, 30000 ;
pOutVideoStream->codec->time_base= (AVRational) 1, 30000 ;
For each frame I increment the dts/pts by 1000

What am I doing wrong here ? why the file is playing choppy ( 1 fps ) ?

Any help will be appreciated.
