@Ronald Yes I was hard-coding elementary things as i had problems with the segmentation faults. and buffer underflows. I am guessing this can be setup in a config file or an xml file, if i wanted to keep the inputs simple of if i had a very little need to alter the video settings.
@Michael *I had written the encode and write_to_frame functions after i got the decoded frame.* * I had commented out the avcodec_encode_video part after which i called the av_interleaved_write or av_write_frame. * seeing i had encountered the problem at this junction i omitted them from the code posted. 1. do we need to enable PST DST settings for a basic decode-encode? i have been trying to strip away the code bits of ffmpeg.c but have been unsuccessful at it. 2. What kind of formatting must be done for the output file codec context besides finding relevant codec and opening them to allow for writing the data packets onto it. 3. Also if i had to encode the video into multiple formats. would it not mean that i simply call the relevant encode and write calls in after i get the decoded frame. Am i right in assuming the decoded video data ( interleaved audio/video data) is the same for any encoder input format. Thanks. On Tue, May 10, 2011 at 11:26 PM, Ronald S.
