根据视频都桢计算，framesxframe rate/sample rate


​Hi Powerpan,




That only works for some codecs: those having fixed frame size. Codecs with no fixed frame size ​can't be handled in this way, right?

解多少桢就插多少桢


​Thanks powerpan,




I think I need to know how many samples this packet contains to insert same number of silent samples, but number of samples is in decoded_frame, when decode fails, the fields in decoded_frame have no meaning.

Hi there,




When running my program with an audio-broken file, at some point avcodec_decode_audio4 returns < 0 which mean decode failure.


It's okay for me to add silence to makeup the decode failure but how can I know how many silent samples to insert?


Thanks
