[Libav-user] error while writing to abuffer

[Yamusani Vinay]

Hi All,

      I used some filters and try to decode the audio and applied the
filters to decoded frame.But for most of the mp3 songs..it is working
perfectly.But for some songs..I am getting error at below mentioned code..

static AVFilterContext *abuffer_ctx = NULL;

snprintf(strbuf, sizeof(strbuf),

  "time_base=%d/%d:sample_rate=%d:sample_fmt=%s:channel_layout=0x%"PRIx64,

  time_base.num, time_base.den, avctx->sample_rate,

  av_get_sample_fmt_name(avctx->sample_fmt),

  avctx->channel_layout);


 err = avfilter_graph_create_filter(&abuffer_ctx, abuffer, NULL,
strbuf,NULL, filter_graph);


 if (err < 0)

 {

 LOGI("error initializing abuffer filter\n");

 return err;

 }

 else

 {

 LOGE("success initializing abuffer filter\n");

 }

int err = av_buffersrc_write_frame(abuffer_ctx, frame);

  av_frame_unref(frame);

av_frame_free(&frame);

  if (err < 0)

  {

      LOGE("error writing frame to buffersrc\n");

  }


By using the above code for some mp3 songs I am getting the log message
"error writing frame to buffersrc\n".So please help me in resolving this
problem.


Thanks & Regards,

bitfield.
