<div style="FONT-SIZE:11pt;FONT-FAMILY:Calibri,sans-serif">I am currently trying to read the audio samples from a video file. I <br>tried the sample code provided in the examples section <br>decoding_encoding.c and i only changed the <br>
avcodec_find_decoder(AV_CODEC_ID_MP2) to <br>avcodec_find_decoder(pCodecCtx->codec_id), everything works fine with <br>this till i reach the avcodec_decode_audio4() where i get a negative <br>value from this function.<br>
I managed my way through video decoding sucesfully but seem to be <br>stucked here from a long time. i tried with .mts and .mp4 file and even <br>.mp3 file but all seem to return a negative value.<br><br>Thank you.</div>
