Hi all,

I am facing some issues in muxing H264 stream with FLV format from a

TEST INPUT  DETAILS (CodecH264.264 ) :

Display Aspect ratio : 2.35
Frame rate : 12.500 fps
Chroma : 4:2:0
Interlacement : Progressive

gst-launch -v filesrc location=/home/CodecH264.264 ! h264parse ! ffmux_asf !
filesink location=/home/FLV/Test1.flv

test2.flv is generated  but when played in Flash player, video played with
blank screen ( with seeking, no video)

gst-launch videotestsrc ! x264enc ! ffmux_flv ! filesink
But when I tried with videotestsrc its muxing to FLV and will be able to

Pls help me out in solving this issue. Thanks in advance.

Re: Pipeline error


If you are having issues muxing H264 stream with FLV format from a filesource, here are some possible solutions you can try:

Check the video stream: Ensure that the H264 video stream you are trying to mux is valid and has all the necessary headers. You can use a tool like FFmpeg to check the stream for errors and to add missing headers if necessary.

Check the FLV file format: Ensure that the FLV file format you are using is compatible with the H264 stream. You can try using a different FLV file format or a different muxing tool to see if the issue persists.
