>> You have declared function as:
>> AVRational av_guess_sample_aspect_ratio(AVFormatContext *format,
>> AVStream *stream, AVFrame *frame)
>> This makes it hard to use the function if there is no AVFrame. (ie

> You can use NULL in that case for AVFrame. The function handles it.
Yes, but it handles it by not using any codec parameters.
stream->codec->sample_aspect_ratio would be better to use in that
