Hi all,

I use gstreamer to transcode MP4 file to TS file has the following erro（At present, only this MP4 file has this problem）：

*** Error in `./gst_transcode': realloc(): invalid next size: 0x7437af60 ***

Re: Use gstreamer to transcode MP4 file to ts file erro

Hello,

can you please try with the below gstreamer pipeline.

gst-launch-1.0 filesrc location=<your mp4 file> ! qtdemux name=d ! queue ! h264parse ! mpegtsmux name=mux ! filesink location=<your output file> d. ! queue ! aacparse ! mux.

Hope this could help you.

Best regards,

Diego.
